Samsung Galaxy S2 i9100 Jelly Bean 4.1.2 (XWLSD) Firmware

Updated: Samsung Galaxy S2 i9100 Jelly Bean 4.1.2 (XWLSJ) Firmware

The interwebs were set ablaze last month when Samsung officially launched the long-awaited Samsung Galaxy S2 Jelly Bean 4.1.2 Firmware. Galaxy S2 owners rejoiced even if their update Jelly Bean firmware wasn’t avaiable for their region or country yet. Technically speaking anyone with the international unlocked version of the Samsung Galaxy S2 i9100 can flash their devices with official firmware. In this case the Jelly Bean Firmware was from Spain.

An Updated Jelly Bean Firmware for the Samsung Galaxy S2

I have already produced a video and wrote an article on the previous XWLS8 Jelly Bean Firmware for the Samsung Galaxy S2 i9100 last month. Nonetheless, several folks were asking me on my YouTube channel whether they should flash their devices with the XWLS8 (Jan 2013), XWLSD (Feb 2013) and XWLSE (Feb 2013 – Russia). Thus, I decided to create another video and guide for you guys, this time for the XWLSD firmware.

What’s the difference between XWLS8, XWLSD and XWLSE?

The first official Android Jelly Bean 4.1.2 Firmware for the Samsung Galaxy S2 was the XWLS8 which was intended for Spain. The XWLSD was an updated version of the XWLS8 Jelly Bean 4.1.2 again intended for the Spanish market. The XWLSD included several bug fixes found on the previous XWLS8 version. On the other hand, the XWLSE which is the latest firmware version is targeted to Russian market. The only difference between Spain’s XWLSD and Russia’s the XWLSE are the build numbers. No changes or bug fixes whatsoever.

Guide: Install and Flash the Official Samsung Galaxy S2 Jelly Bean 4.1.2 XWLSD Firmware

Want to be updated with the latest XWLSD Jelly Bean Firmware build from Samsung? You can easily do so simply by following these instructions below.

Note: This won’t work on AT&T, Verizon, Sprint and T-Mobile versions of the Samsung Galaxy S2. The device has to be the international unlocked version of the Galaxy S2.

  1. Download the Spanish Firmware (I9100XWLSD) V 4.1.2 (Jelly Bean) and extract it to a folder. You would need .TAR file to flash your Samsung Galaxy S2 device.
  2. Download Odin 3.07 and run it. It’s best that you have Samsung Kies already installed as this will provide communication between your Samsung Galaxy S2 and your computer.
  3. Power Off your Samsung Galaxy S2 i9100 and set it in Download Mode by pressing Volume Down + Menu Button + Power Button for 10 seconds.
  4. Once in Download Mode, connect your Micro-USB cable to your computer and press Volume Up to activate Download Mode. A box will appear in Odin signifying a successful connection.
  5. Click PDA in Odin and find the contents of the I9100XWLSD.zip file you extracted earlier on We’re looking for the following filename “I9100XWLSD_I9100FOPLS4_I9100XXLS8_HOME.tar“. Press Start.
  6. The flashing procedure would normally last five to ten minutes. The device would automatically boot.
  7. Note: If you are coming from a Custom ROM or Kernel it would usually get stuck at the Samsung boot screen. This is normal due to platform issues. Nevertheless, remove the battery from the Samsung Galaxy S2 and disconnect all cables. Insert the battery back in and instead of turning it on, access Recovery Mode by pressing Volume Up + Menu Button + Power Button for 10 seconds. The screen would flash twice. Once in Recovery Mode, do a Wipe Data/Factory Reset and Wipe Cache Partition. Lastly, reboot your phone and everything should be in working order.

    can be used in indonesia? :o
    if firmware is asking about the pin? as some people say?
    stable and fix battery issues draining? sorry for my bad english hehe..

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      Hi Windano. Yes it can be used in Indonesia as along as it is the international unlocked version of the Galaxy S2 i9100.

      • windano eka

        thanks jose!
        this can make improvement in battery life?

        • http://www.wiredmash.com/ Jose Francisco Farrugia

          Personally, not much of an improvement. Basically, it’s the same. I suggest you upgrade since it has Project Butter which provides a smooth user experience.

          • vinr

            For me personally, the battery life has deteriorated terribly. I’m planning to either revoke or install a custom rom now as I can’t find the reason why the battery life is so bad :-(

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            I didn’t quite notice it. How bad was it? Can you give us a few more details? Perhaps your usage?

          • vinr

            I installed XWLSE on UK i9100. From the day 1 I could see problems with the batter usage. Mostly the screen showed as high usage. I finally rooted it siyah 6b4 and that didn’t change anything. yesterday used battery to delete the file and start from scratch with 100% full batter. switched off wifi, auto sync and pretty much anything that can eat data for 6 hours while I was in bed. Took a call under a minute and 3-4 text messages. 3-4 times I have checked my emails and thats it. The battery died within 16 hours. Its terrible. Do you think XWLSD will be any different? Worth trying?

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            If you came from a Custom ROM or Kernel, I suggest you give your phone a little bit of time so that it can calibrate the battery again. I suggest you try the XWLSD as the XWLSE is pretty much just like XWLSD with a few Russian files added. Give it a shot! Let me know how it goes.

            Moreover, try reconditioning your battery by discharging it fully, all the way down to 0%, and charging it when the phone is off for a few hours. This might improve battery life :)

      • visual desine

        the error your getting in odin is because of your lead, i had same issue, and i to thought my cell was bricked, but i luckly had another lead, and it worked fine, so i would say yes its your lead, if nothing else works ok

        • http://www.wiredmash.com/ Jose Francisco Farrugia

          Thanks for the added info. A few folks on YouTube had some issues where they thought they “bricked” their phone because it was not completing the flashing process.

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      You can root the XWLSD firmware by downloading and flashing the Siyah Kernel. I’ll be making a video on how to root the Samsung Galaxy S2 running on the XWLSD firmware soon. Stay tuned for that :)

  • David Loman

    Actually, it can be installed in any Galaxy S2 with code name GT I9100, leaving aside the ones from T mobile, sprint and at&t. Most of the S2′s sold outside the US are the international version. With “international” it is meant, those devices which are sold outside the US. It usually is that way. I just thought I should mention it since most people don’t flash their devices since their phones are with a carrier and think that makes their phones a “non international version”

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      Hi David. Thank you for clearing that up. I just had a few folks who had issues with their locked Samsung Galaxy S2 units when they were prompted with an Unlock PIN screen as soon as they flashed the official Jelly Bean firmware. I have directed them to install an unlock App to generate the code, however, it hasn’t worked. Any suggestions? Thanks!

  • raney

    what should i do?, its not downloading

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      What is not Downloading? The Firmware? Or is it not going to Download Mode?

      • raney

        it did go to download mode but after i press the start button in odin. then boom. it didnt download. no progress -.-

        • http://www.wiredmash.com/ Jose Francisco Farrugia

          Try doing what I suggested above. Restart the whole flashing process. :) Keep me updated.

          • raney

            what should be check in odin?

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            Is Samsung Kies installed? If you are having problems with Odin 3.07 try 1.85

          • raney

            yep. kies is installed

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            Try downgrading to V 1.85 of Odin. And do a reboot of your computer.

          • raney

            odin check pls. what should be check in here? odin v1.85

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            should the tar file have md5 at the last?

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            Yeah it should have, however, I believe the filetype is already .tar.md5

          • raney

            yeah it is.

          • http://www.wiredmash.com/ Jose Francisco Farrugia

    • raney

      here it is.. what should i do

      • http://www.wiredmash.com/ Jose Francisco Farrugia

        How long has it been like this? Give it 10 minutes or so. If it gets stuck try removing the USB and powering off the phone by removing the battery. Place the battery back in and boot it in Download Mode and repeat the same process. You are flashing an international unlocked version right?

        • raney

          its already 20 minutes dude or so. :( i dont want to lose my phone

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            i have

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            Okay. I suggest you do this on another computer. Your computer might be having some communication issues with your Samsung Galaxy S2.

          • raney

            dude, i just brick my phone

          • http://www.wiredmash.com/ Jose Francisco Farrugia

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            Okay. Here’s my suggestion. Download XWLS8 from here sammobile.com and try flashing it with that. If it still unsuccessful flash it with the original ICS – http://www.wiredmash.com/how-to-unroot-samsung-galaxy-s2-i9100/

It also says camera failed again ang again ; ( how do I fix this. I dont want to loose ky fone :( somebody help me here ? :( please..

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            That’s indeed strange. Is your phone rooted? Try reflashing the Samsung Jelly Bean Firmware. If that doesn’t work try doing a Wipe Partition (all data will be erased), wipe cache and wipe dalvik cache too.

          • Ryan Dingle

            My phone is not rooted sir. I tried 2 – 3 times wiping all.. but it doesnt work. How can I fix this sir. Please help me :(

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            I suggest you you Reset the Phone from the Settings Menu and see if the problem disappears. If still doesn’t work reflash the XWLSD Firmware Image.

          • Ryan Dingle

            Wt Du u mean by reflash sir? I update it again via odin sir ? I tried also to reset factory settings but its having the same problem. I try to flashing it again sir.

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            Yes, reflash it via Odin.

          • Ryan Dingle

            I will do it sir. I just need to recharge my phone cause its empty .
            I will reply after i reflash and having some changes. Thankyou for your consideration :)

            Ah another Pinoy :)

            That’s indeed strange Ryan in regards to your camera issue. Did you camera work fine on the UAE/Middle East firmware? If you are having problems I suggest you revert back to the official ICS UAE Firmware.

          • Ryan Dingle

            Yes sir. It works fine on the ICS UAE.

            hmm but if i revert back to it i will go back to my stock.
            i want to upgrade it.

            is the UAE/Middle east official jellybean has bean released sir?

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            Unfortunately, it hasn’t been released yet. You can check out http://www.sammobile.com for updates to the firmware ;)

    Great job for creating this very helpful page! I also saw your video tutorial on YouTube on how to flash JB 4.1.2. I followed the process but there seemed to be a problem with my netbook (or Odin?) as it could not show the bottom part of Odin 3.07 (the part where the start button is found). As a result, I called off my plan of installing the firmware with hope that the official update via Kies would come out soon. I am not sure though if I could still wait any longer. I have just bookmarked your page, and I hope that when I finally decide to flash the JB firmware on my unit (perhaps this weekend or next week), you will be here to extend your assistance. Keep up the good work WiredMash!

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      Hi Benjamin. Thank you for your kind words. :) I believe it’s an issue with your resolution on your netbook. What’s the screen size and resolution?

      • http://www.facebook.com/people/Benjamin-Torres-Santiago/100000732064185 Benjamin Torres Santiago

        I also thought so. I believe it’s the highest (1024×600) and the screen size is that of a typical netbook. (10.1). I tried googling the problem and followed some advice here on the net like adjusting the resolution, DPI etc but none worked. Actually, one worked but I had to make adjustments with the appearance of the screen like making everything in portrait mode. I was able to see the start button in Odin but controlling the pointer/cursor was another story. Is there other possible way that I could flash this firmware in my unit? A different version of Odin perhaps? Do you have any idea as to when Samsung Philippines will officially update S2 in our country? Thanks so much for your help.

        • http://www.wiredmash.com/ Jose Francisco Farrugia

          You can try Odin version 1.85 (http://ul.to/xt4607xx), perhaps the window size is a lot smaller. In regards to the official firmware being launched in the Philippines all I can say, I hope it’s soon ;)

          In regards to your resolution issue, you can try outputting your display onto an external monitor?

          • http://www.facebook.com/people/Benjamin-Torres-Santiago/100000732064185 Benjamin Torres Santiago

            Hi! Thank you for the advice. I downloaded Odin 1.85. I think I can use it as the start button is located in the middle of the page/dialogue box. I just have a question before I proceed with the flashing process. Should I remove my SIM card before I flash the firmware update? Thanks in advance.

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            You don’t really need to, however, if you wish you can. Is your i9100 from a network carrier?

          • http://www.facebook.com/people/Benjamin-Torres-Santiago/100000732064185 Benjamin Torres Santiago

            No it’s not, so I suppose I’m using an unlocked version. Lastly, once the update is done successfully, should I still do the 7th step above (access Recovery Mode by pressing Volume Up + Menu Button + Power Button for 10 seconds. The screen would flash twice. Once in Recovery Mode, do a Wipe Data/Factory Reset and Wipe Cache Partition.) (NOTE: my unit is not rooted and it will be the first time for me to update it via Odin)

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            I guess it’s not locked too. In regards to Recovery Mode, it depends. If your phone doesn’t boot up after 5 minutes (It usually takes sometime to boot up) you can boot up into Recovery Mode. However, I don’t think you’ll need to bootup since it’s basically updating your ICS Firmware.

          • http://www.facebook.com/people/Benjamin-Torres-Santiago/100000732064185 Benjamin Torres Santiago

            Thanks so much! I will keep you posted as soon as I’m done updating the firmware, but it might take some time as it takes years to download the JB file here at the office (ooops, hope my boss doesn’t read this. hehe!). I once had the file but decided to dispose of it last week due to the problem I encountered with Odin 3.07. I’ll just do the flashing of the firmware update at home. Again, many thanks and keep it up!

    I am about to download the file and will update my SII afterwards. as for my last question just to be on a safer side, is there a way to know or find out whether the unit is unlocked or locked to a carrier?

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      Hi Ben. You can try inputting this *#SIMLOCK#

  • http://www.facebook.com/people/Benjamin-Torres-Santiago/100000732064185 Benjamin Torres Santiago

    I’ve just ported the fw update in my 18-month old SII, following the steps enumerated above. I had a minor problem at first, but it was immediately resolved after I changed the USB cable. The first one was probably the reason why my three attempts were unsuccessful. Thanks to one of the posts in the threads. I probably had the same problem. Anyway, I have the JB 4.1.2 right now and it works like a charm. I didn’t have to remove my SIM prior to the update and no problem encountered during and after the process. My phone right now has a very different feel and look. I haven’t noticed any problem yet as I am still scrutinizing all new features of the phone. Thanks so much for your help!

    I just have one question. I saw some videos where the Google search showcased its Siri-like intelligence. How can I see/use that function? I’ve asked questions but the application would only direct my answers to the web.

        I saw a couple of videos where the Google Voice search engine (from SIII and other android devices) responds to questions. I believe you can even choose between a male or a female voice. I wonder if the Google Voice that I have here has that feature. I just wanted to hear my phone talk and answer my questions, that’s all. hehe!

        • http://www.wiredmash.com/ Jose Francisco Farrugia

          I guess you saw how Samsung’s version of Siri operates. Google Voice is something else though. It’s similar to Skype – Voice Calls. I believe you’re talking about Google Now. Check out Google Now on YouTube :)

          • http://www.facebook.com/people/Benjamin-Torres-Santiago/100000732064185 Benjamin Torres Santiago

            I finally figured out how it could function. I needed to open Google location services for the voice to be activated. I must say the voice (of a woman) sounds so natural than that of Siri.:)

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            It does indeed :) Great! Enjoy Jelly Bean ;)

          • http://www.facebook.com/people/Benjamin-Torres-Santiago/100000732064185 Benjamin Torres Santiago

            i wonder though if the voice could be changed to a man’s voice.

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            Why would you want a man’s voice? ;)

          • http://www.facebook.com/people/Benjamin-Torres-Santiago/100000732064185 Benjamin Torres Santiago

            Coz I’m into a man?lol! I just wanted to check which one sounds better than the other. I can’t seem to figure out how other users of android devices manage to make that function.

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            Haha! Perhaps they’re using a third party app? Try checking out the Play Store for other virtual assistants?

    I don’t know if you experience the same problem, but whenever I play a video from the internet and place it on full screen mode, the video does not go back to its original size when pressing the back button (touch key light). The only way to stop the video from playing is by pressing the home button, thus closing the internet application. I tried rebooting the device, with hope that it would do the trick but the problem is still there. In addition, whenever I receive a notification (ex.game and facebook notifications), the phone vibrates, and it still does even if I have already made changes in the settings. (JB 4.1.2 WXLSD)

      Hi Ben. I am leaning towards software issues – bug issues in particular.

    • kurtis

      i have that problem :(

      • http://www.wiredmash.com/ Jose Francisco Farrugia

        Looks like it’s indeed a bug. I’ll check it out.

    • Mazdamer

      If it’s the Galaxy S2 International model (GT-i9100). Yes, it would work.

  • syahmie7

    hai i have a problem my s2 android version is 2.3.4 so can i upgrade to this version? i already follow all your insruction but failed..hope u can help me.. tqvm

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      Yes, you can very upgrade it to this version if it’s the GT-I9100 version. What’s wrong mate?

  • kelvin

    is it ok to upate my S2 i9100 international version stock gingerbread 2.3.4 not rooted to the latest official jeally bean 4.1.2???

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      Yeah, that’s fine mate :)

  • Chathu2k4

    Hello im also from sri Lanka & using Galaxy S2 GT i9100, running 4.0.4. Below details are specs. Hope this is a T mobile (Germany – DTM ) carrier branded unlocked version & working fine with networks here.

    PDA : I9100BOLPM
    PHONE : I9100BOLP7
    CSC : I9100DTMLPF

    I want to update it to official 4.1.2 & please advice me that will this works for my phone without facing any network lock or brick? Or do i wait for their original release?
    Thank you.

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      As long as it’s a GT-i9100 it should work. However, do you have the network unlock code just in case? You can always download an application to generate a network unlock code too. You can ask at http://www.xda-developers.com

  • kelvin

    thanks dude… by the way is it ok if i dont full wife or restore
    factor system my S2 before upgrading ng phone to official jeally bean
    using your tutorial??

    and how do i know if my samsung GT I9100 is international unlocked??

    because
    when i check my phone model in the phone settings its only display
    GT-I9100. I’m new user of android phone here in my country at the
    philippines. thankyou sir!. :)

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      As long as your phone is a GT-i9100 you can flash it to the XWLSD firmware. :) And I don’t quite understand your first question.

  • kelvin

    is it ok if i used samsung USB driver rather than samsung kies??? because some people say that if kies is running in the background during updating, the might be cause of problem… thats why they said make sure that kies is not running in the background and i dont know how to check it. thanks…

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      If the program is not open then it’s not running. You can always check the Task Manager and see if Samsung Kies is running or not. Install Samsung Kies fully and exit it when you are using Odin.

      • kelvin

        ok sir, thankyou for your help and hopefully this thread will always be updated for the jeallybean firmware with the development of battery performance, notification issues and predictive text issues. thankyou sir! :)

        • http://www.wiredmash.com/ Jose Francisco Farrugia

          You’re welcome. I’ll continually update WiredMash if there are any new developments :)

  • http://www.facebook.com/anna.anderson.927980 Anna Anderson

    Just wanted to say a big thank you for the article and helpful tips. I got tired of waiting for JB in my region and went looking for a simple description of manual update, and very glad I came across your article. Downloaded and installed everything in one go, biggest problems were – waiting half hour for firmware to download from hotfile (I’m incredibly impatient) and minor scare when I realised I wiped some notes (that’s what impatient does to ya!), but it’s all backdated, so I’m a happy new resident of JB land and loving it so far.
    PS I checked for all the issues highlighted here in the comments and didn’t find any obvious problems (I used Odin 3.07 and XWLSE firmware)

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      Hi Anna. I am glad everything worked out fine with you. I got impatient too waiting for the Jelly Bean firmware update for my region (Philippines). Though the XWLSD seems to have some issues with regards to notification sounds, predictive text issues and battery performance. I am thinking of trying out a much updated firmware for the i9100 from another region.

      • http://www.facebook.com/anna.anderson.927980 Anna Anderson

        Hi Jose. Which version are you thinking of trying? In the past 12 hours I noticed a much decreased battery life myself, usually after a full charge it’d show at least a day and a half life. It was noted here earlier that device may need to recalibrate battery for the new firmware, so I let it discharge completely and charged while switched off – it’s showed only 24 hours of life. I’m hoping it’ll improve with time, since I use phone a lot through the day. Otherwise, I’ll try a newer version of firmware. Let me know which one works out for you better.

        • http://www.wiredmash.com/ Jose Francisco Farrugia

          Hi Anna. I am currently using the XWLSD version and I intend to try out your version, however, seems that both have issues with battery life. I believe there’s a newer updated version which is already available according to http://www.sammobile.com

          There’s one for Brazil (I9100VJLPD), however, I am hesitant to try it.

          • http://www.facebook.com/anna.anderson.927980 Anna Anderson

            I see, I looked through the list on sammobile, there are a lot region specific releases since XWLSD and XWLSE, guess they are just variations without any improvement.
            Out of general curiosity, why are you hesitant in trying the Brazil version?

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            There might be some differences, however, I highly doubt. Perhaps I’ll give it a go soon. I’ll still observe how the XWLSD firmware.

  • kelvin

    ok sir, thankyou for your help and hopefully this thread will always be
    updated for the jeallybean firmware with the development of battery
    performance, notification issues and predictive text issues. thankyou

      Hi There. That’s the first time I have heard of that. Have you tried checking in the Accessibility settings on your phone?

  • Mehul

    Updated with xwlsd. Works great. One problem though. Gmail account doesn’t work with Microsoft exchange active sync.
    It used to work previously before updating to jellybeans.

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      Great! Why don’t you use the Gmail App?

  • Blanaru Chris

    Hello. I have a S2 smarthphone from Romania, unlocked. With my original firmware I9100XWLP7, the phone had many restarts while accesing Wi-fi/Bluetooth. I did an upgrade to 4.1.2 from nordic countries, and even from Ukraine, but with both firmwares the phone has problems. The battery is discharging quickly, my statusbar has problems sometimes, I mean it doesn’t slide down when I want, (it repairs after restart), and after I install 5-6 applications, it starts to go slowly in menus…etc. My constantly free RAM memory is 200 MB, which is very low. I went to 4.0.4 9100BVLPH, but I don’t like ICS even though the phone works very good.
    This version of JB from Spain works good, or it has the same problems like
    the version of Jelly Bean that I wrote below? Thank you.

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      The XWLSD Firmware (Jelly Bean Firmware from Spain) works pretty good. There are a few bug, but other than that, it’s fine :)

    • nemezis93

      You got your phone from RDS? And your original firmware was I9100XWLP7? Thanks for the answer.

      • http://www.wiredmash.com/ Jose Francisco Farrugia

        What do you mean by RDS? I can’t recall what the original firmware was.

  • http://www.facebook.com/louie.macapus Louie Macapus

    i’m using a insecured kernel should i go back to secured kernel before flashing? thx

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      What do you mean by an unsecured kernel? A Custom Kernel? You can easily flash back the Official Samsung Firmware to get the Samsung Kernel back ;)

    what happen if you flash ur s2 in this OS but ur phone is not International Unlock?

  • kenmoxly

    Awesome post man ;) i just downloaded the firmware but on your video you say that it will erase all my data,so apart from google sync,is there another backup option for my unrooted s2? will the update erase all my contacts,apps,texts,etc?

  • Marina

    Hello! I didn’t want to update my phone, but without notice it I had the automatic update option on. I only have my galaxy s2 for one month, so i am a complete inexpert :D. However I had to practical problems. (1) I could not install the “Polaris office” from google play. It said it was incompatible with my device. However from Aptoie I could and now is working fine. (2) The Photo Editor from samsung I could also not install from samsung app page and also not from google play. I got the same message of incompatibility. This I could not solve, and I had to get another photo editor. Do you no if this is a temporary mistake or this apps are really incompatible with the s2? Thanks a lot!!

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      Hi Marina. Can you check the version of Android on your Samsung Galaxy S2? Settings > About Phone. Polaris Office and the Photo Editor from Samsung should be pre-installed. I find it strange that you had to download it. Perhaps, you got a custom ROM phone? Is it second hand?

  • Vishal

    I downloaded the firmware and followed every instruction above. the download always got stuck at the finishing point and was never completed. i tried to reboot my phone after that and its been stuck on the boot screen. factory reset doesnt help too. ive tried everything and nothing works. DO NOT DOWNLOAD!

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      Hi Vishal. If it didn’t work on your end it doesn’t mean it doesn’t work for anyone else ;) It might be an issue with computer. Do you have Samsung Kies installed? Try re-installing it as the drivers might have been corrupted.

      If that doesn’t work use another computer to flash the XWLSD Firmware.

      • DT

        Make sure your Not using Galaxy 3 Firmware and its From the correct Country or Zone and from the origanal vendor or phone service provider

      I dont know who uploaded this file but i think this file work properly.
      my phone is samsung galaxy s2 and I am stuck with gingerbread 2.3.6 firmware. There are some issue’s regarding about the chip that the Samsung galaxy s2 and other phone have like samsung galaxy note but not all phone have this chip. This chip only malfunction when if its triggered. like when you are flashing some firmware in your phone. the chip cant perform some of the stages of flashing new firmware higher than gingerbread. so be carefull.

      think before you click :)

        Hi Jr. As long as you have the GT-i9100 of the Samsung Galaxy S2, everything should work fine :)

    This jellybean software is a disaster. My Galaxy S2 battery now only lasts about 6 hours from fully charged. Previously it would last for 24 hours with data and wifi on and about three days with data turned off. Now, even with everything turned off it won’t last a working day. Does anyone know how i can go back to the way it was before as this situation is completely untenable?

    i cant use my phone! I have a samsung galaxy s2 and once it restarted it asks for a network sim pin that i dont know. Help!!!!

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      Looks like your phone was initially network locked. Have you tried calling your network asking for the PIN, that’s if you purchased the phone from your network carrier. If you didn’t, I suggest you root your phone and install a Galaxy S2 unlock pin App from the App Store :) http://www.wiredmash.com/how-to-root-samsung-galaxy-s2-i9100-jelly-bean-4-1-2/

      Let me know how it goes :)

    hey i need help I recently upgrade my s2, just last night. But while updating I got stuck on this screen, it shows me this:

    Android system recovery

    Volume up/down to move highlight:
    power button to select.

    reboot system now
    apply update from external storage
    wipe data/factory reset
    wipe cache partition
    apply update from cache

    I already click everything but when it turns on it still gives me the same screen. Pls. Help. thanks

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      That’s quite strange. Why don’t you flash the XWLSJ Firmware build instead of using the older XWLSD firmware ;) http://www.wiredmash.com/samsung-galaxy-s2-i9100-jelly-bean-4-1-2-xwlsj-firmware-march-2013/

      • mae

        hi thank you so much for your response… I dont understand the terms :P Im so sorry… can you give me step by step instruction.. so sorry.. But I really need help..

        • http://www.wiredmash.com/ Jose Francisco Farrugia

          Perhaps it got stuck during the updating procedure. Have you tried doing a Wipe Partition (Factory Reset) and then a Wipe Cache, after? Once it’s done, select reboot your phone. Let me know how it goes after :)

          • mae

            hi I already did all those, but after rebooting the screen was still the same… :(

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            Okay, why don’t you flash the latest XWLSJ firmware instead – http://www.wiredmash.com/samsung-galaxy-s2-i9100-jelly-bean-4-1-2-xwlsj-firmware-march-2013/

          • mae

            Are your photos stored on an external SD Card?

          • mae

            Im not sure… if my recent photos are stored in my external sd card. but i think its in my phones memory.. oh no..

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            I am a little bit surprised that none of my solutions helped you out. :( Did you root, install a custom ROM or flash one of the latest Jelly Bean firmwares via Odin?

          • mae

            No , i just dont do any of the flashing yet. coz im not sure if i can. Im just affraid that it worsen my case. But I will try.

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            Mae, try following this in-depth guide in flashing your Samsung Galaxy S2 to the latest Jelly Bean Firmware (XWLSJ) – http://www.wiredmash.com/samsung-galaxy-s2-i9100-jelly-bean-4-1-2-xwlsj-firmware-march-2013/

          • mae

            what happens when i flash? what will it do to my phone? sorry jose..

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            There’s no need for you to apologize. It’s fine :) Flashing the original Samsung Firmware (XWLSJ) will update your phone to the latest version of Android which is Jelly Bean. I am assuming you are on Ice Cream Sandwich (4.0) right now?

          • mae

            yes its ice cream sandwich… I hope I can do this..

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            I am sure you can. You just have to follow the guide step by step and all will be well. :) Is your Galaxy S2 still under warranty?

          • mae

            No. Its no longer in warranty. why?

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            If it was under warranty you could have brought it back to the Samsung Service Center and have it fixed for free ;)

          • mae

            unfortunately this was a gift :p thank you for your help. I will just try your advise and update you when my phone is ok.. :) thanks again

          • mae

            how will I know if I have enough memory for this? will the memory affects the update Im about to run again?

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            I am sure you have enough space. The update is around 500MB. Do you recall how much free space you had left?

          • mae

            hey jose, I need your help, I hope you remembered my problem, Is the program here in the Philippines compatible in may SII? I had may phone from UK i guess , because its a gift.. I badly need your response.

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            Hi Mae. What program are you talking about? XWLSD? Yes, it works flawlessly. But I suggest XWLSJ – http://www.wiredmash.com/samsung-galaxy-s2-i9100-jelly-bean-4-1-2-xwlsj-firmware-march-2013/

            The XWLSJ Build is a lot better.

          • mae

            Is flashing different from rooting? thanks..

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            Hi Mae. Flashing is the term used to “install” a ROM, a Firmware or a Kernel. Rooting can be associated with flashing as you are installing a new Kernel to ROOT your phone ;) Did that make sense? haha

          • mae

            hahaha thanks JOse. uhm, is the XWLSJ is rooting process? :)

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            XWLSJ is flashing a new firmware update. It’s like updating your Android OS to Jelly Bean. ;)

          • mae

            thank you… I had it fjxed in Samsung care center.. But I forgot to ask if they already upgraded it to jellybean.. And sadly they didn’t.

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            Are you willing to wait for the official Samsung Jelly Bean Firmware for the Philippines? Give it a couple of months. It should be here by June the latest.

      Hi Mohan. Remove the battery. Press the Volume UP + Home Button + Power Button for 10 seconds. The screen should flash twice with the logo of Samsung. Once in Recovery Mode to a Wipe Partition and Wipe Cache. And reboot :) Should work fine after.

    I Guess the best rom for the s2 with that battery And hardware is still the ICS over th jelly bean. After using 4.1.2 for a month Now… i decide to roll back for 4.0.4 CyanogenMod . It uses best the battery that 4.1.2 i Guess because there funciotions designed for phones with better cpu that the good old S2….

    This has worked a treat for the situation i have found myself in as of yesterday. I turned on my phone to find my sim card was not being recognised. For the better part of 12 hours straight i have been desperately scouring the internet trying to find someone who had the same problem and found a solution. I found myself on this page and decided to upgrade to Jelly Bean as a last ditch effort before contemplating the purchase of a new phone. To my surprise the sim card is now being recognised and as a bonus i have Jelly Bean working great guns. Thanks very much :D

      Hi there. I highly suggest you do a factory reset. Settings > Backup & Reset.

      • Deepak MS

        Thanks jose for replying..Ru sure if i do factory reset will solve the problem..

        • http://www.wiredmash.com/ Jose Francisco Farrugia

    sorry, i just wanna know. why it get stuck at that part?? =O

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      How long has it been stuck on that part? Try changing your USB Cable ;)

      • http://twitter.com/HafizIthninLOL Lol =)

        still the same. how? =(

        • http://www.wiredmash.com/ Jose Francisco Farrugia

          Have you tried reinstalling Samsung Kies? Don’t forget the drivers too.

          • http://twitter.com/HafizIthninLOL Lol =)

            need to update the samsung kies or what? drivers? got the link? need help! T-T now i couldnt turn on my phone. it keep showing logo of phone need to connect to the PC. but when do that, it keep saying “unpluged” T-T

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            Reinstall Samsung Kies on your Computer. It includes the drivers in the installation package.

            The reason why your phone is not booting up is due to the fact that the flashing procedure hasn’t completed.

          • http://twitter.com/HafizIthninLOL Lol =)

            i left it about an hour, it like freeze there. i thought there is something. so i unpluged it. =3

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            I highly suggest you use a good quality micro-usb cable. That is mostly like the case why it freezes up. You can try using another computer though.

          • http://twitter.com/HafizIthninLOL Lol =)

            i try already. but nothing happen. same, got stuck. T-T

    Ice Cream Sandwich if far way better than Jelly Bean 4.1.2., can someone help me on how to roll back to ICS 4.0?

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      Hi Sam. I beg to differ. Jelly Bean is definitely a lot smoother compared to ICS. Have you tried the latest XWLSN or XWLSS Firmware?

  • rain

    francisco :), any new update?

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      I have got the latest XWLSS Installation Guide up already. Have you seen it? :)

    Hi jose. I have updated my s2 to jb via kies the other day. It was running smoothly then i noticed that everytime i tried to turn my phone off, it turns on right away.. just like when you reset the fone. So what i did was i removed the battery then put it back again. Then it suddenly turned on even if i did not press the power button. Ive done the factory reset and wipe cache partition 4 times already. But still,same problem. And another thing.. my phone isnt recognize by my pc. Ive tried other pc as well but no luck. I hope you could help me out.

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      Which version of Android are you currently running on? It might be a hardware issue? Perhaps there’s a loose connection on the power/lock button too.

  • DT

    Hi.
    I have Galaxy s2 which is still on Android version 2.3.3. I want to go on Jelly Bean 4.1.2 XXLSD.

    My baseband version: I9100XXKDH,
    build number: GINGERBREAD .XWKDD.
    My phone is rooted (root@dell103#2).

    Is it possible to use this procedure to go directly on jelly bean XXLSD (one for UK market or so)? THX

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      HI Mamik. I suggest you try updating it via Samsung Kies first. You might have an update for your country or region. If you’re only being updated to ICS or if there’s no update, you can follow the latest XWLSS Firmware Update Guide here – http://www.wiredmash.com/samsung-galaxy-s2-jelly-bean-xwlss-firmware-may-2013/

      Hope this helps :)

      • mamik

        HI! Thx for quick reply!
        I tried with Kies but without success. I think because my S2 is not bought from some telecom operator.
        I saw that other people asked similar question, about possibility to do go directly to JB from Gingerbread with your procedure.
        OK, so you think that I can go with XWLSS firmware directly ?

        THX again

        • http://www.wiredmash.com/ Jose Francisco Farrugia

          Sure go ahead and update it to the XWLSS Firmware directly. :) Let me know how it goes. Good luck mate!

          • mamik

            thx, i will let you know…soon :)

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            Keep me in the loop mamik :) Good luck!

          • mamik

            hi. upgrading firmware from XWKDD 2.3.3 to 4.1.2 XWLSS went good, i follow the procedure and whole process last for 15 minutes. i did not do factory reset after or wipe all data from phone and everything works fine except i have to root my S2 with Siyad kernel (and that went well and quick) because of apps that are require root privileges.

            Obviously 4.1.2 JB uses more RAM than Gingerbread because i can see that now I have around 260MB free RAM with same active apps as on 2.3.3 where I had around 450MB free RAM memory.
            I am not satisfied with this RAM situation and i will investigate custom ROMs. Also, there are lots of bloatware from Samsung on phone and I had freeze them with Titanium Backup app.

            What do you suggest to do now? What custom ROM to put on S2?

            THX

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            Hi Mamik. Congratulations again! Why don’t you take a look at CM 10.1? http://www.wiredmash.com/how-to-install-a-custom-rom-on-samsung-galaxy-s2-i9100/

            Follow that guide and download the latest CM 10.1 from the link provided in the guide :) Let me know how it goes.

            Hi.

            I tried NeatROM but there are still Google and Samsungs apps. Then I tried SuperNexus 2.0 MS1 ROM which does not have Samsungs apps and it is very simple. Finally I put AllianceROM without Samsungs and google apps and I am satisfied because it is customizable.

            I am very glad that I finally decide to do upgrade on my S2.

            THANK YOU very much for your help and simple guidelines (change firmware, root, install ROMs…)!

            You are doing great stuff ;)

            I will definitely follow your site.

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            Thank you Mamik for your support. Stay tuned for more ROM Reviews for the Samsung Galaxy S2 :)

        • mamik

          Hi,

          After week of using AllianceROM on my S2 I can report that is very very buggy. freezes on lock screen, mobile turns off when video recording in camera app, lots of crashing on various apps, had to unmount external SD card to be able install some apps…
          Now I flashed back to NeatROM with Blue Ginger Plus Theme. This ROM is stable for now.

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            The AllianceROM isn’t one of my top pics. I rather go for the Vanilla RootBOX ROM ;)

  • BORIS

    THANK YOU VERY MUCH!!!! IT WORKED EXCELLENT!!!

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      Great to hear that Boris :) Glad it worked out just fine.

  • Boris

    Hi Jose. Please advise. Galaxy S2′s battery discharges very very quikly. I didn’t clean the cash. Thank you in advance.

  • aakkkiiii

    i also tried to flash my glaxy s2 with official jellybean but it olways stuck at boot.bin just at the start……….what to do???

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      Try changing your micro usb cable ;) It that doesn’t work try using a different version of Odin. Odin 1.85 or Odin 3.07 :) Let me know how it goes.

    Hi! I updated my Galaxy S2 to 4.1.2 and my camera won’t work. How can I fix the problem?

    • http://www.wiredmash.com/ Jose Francisco Farrugia

      Hi There. Have you tried doing a Factory Reset? Moreover, I suggest you flash the XWLSS Firmware instead. It’s the latest. The XWLSD Firmware Build has a battery leak issue – http://www.wiredmash.com/samsung-galaxy-s2-jelly-bean-xwlss-firmware-may-2013/

      • bbm

        Thanks! I’ll try try to flash the XWLSS Firmware. Do I have to do the backup before flashing?

        • http://www.wiredmash.com/ Jose Francisco Farrugia

          It’s always a good idea to do a backup prior to flashing ;) You never know what might happen.

          • bbm

            Thanks! One more question: where can I download the Firmware you suggested? I’m from Croatia (Europe)…

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            Check out http://www.sammobile.com/firmwares and do a search there :)

          • bbm

            I did it and it works :)!
            Thanks again!!!!!

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            Whooho! :) I still recommend you checking out SamMobile and looking for the firmware of where you bought your phone from.

          • bbm

            I checked on SamMobile and it’s the same firmware (XWLSD) I recently had and the camera didn’t work (I did the automatic update, which my network operator offers.) I hope you understand what I mean :)).
            What do you think? Should I try to install the one from SamMobile and see how it works? But I’m afraid it will be the same as last time…

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            If you haven’t any battery performance issues stick with it ;)

          • bbm

            The battery lasts for one day from the first day I bought it. So nothing has changed :). Thanks again!!!
            Is there an app for an extension of battery life that’s works well?

          • http://www.wiredmash.com/ Jose Francisco Farrugia

            There are a few battery extender Apps available, however, I always use the Power Saver option found on TouchWiz.
