Samsung Galaxy S2 i9100 Android 4.1.2 (XWLSN) Firmware – April 2013

Tensions continue to rise between North Korea and their southern neighbors for the past month, however, this hasn’t affected life at all in South Korea. Samsung have been dashing out with dozens of Android Jelly Bean Firmware updates for the Samsung Galaxy S2 GT-i9100 since January. The latest Firmware labeled, XWLSN, is intended for three regions – Nordic, Baltic and India. Nevertheless, as long as you have the international variant, specifically the Samsung Galaxy S2 GT-i9100, then you can very well flash this update.

What’s New?

I have posted several step-by-step guides in flashing previous firmware – XWLS8, XWLSD, XWLSJ and a review of one of the latest firmware XWLSJ. So what’s new with the XWLSN Firmware build? Simple. They fixed a few bugs and issues with previous builds, one being that the email notification sound is now fixed. I remember one of you guys who complained about that.

Battery Performance on XWLSN

A number of you have asked if there any battery issues with previous firmware builds and the worst I have seen was with the XWLSD build which ate my battery profusely. In regards to the latest firmware, XWLSN, battery performance seems to be fine and normal.

How-To Guide

Note: This procedure and guide is intended for the international variant of the Samsung Galaxy S2 and will not work with AT&T, Verizon, Sprint or T-Mobile variants.

  1. Download the Nordic Firmware (I9100XWLSN) 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 in the background. It’s recommended that Samsung Kies should be installed as this will install the required drivers.
  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 (for example – “COM3). Note: If it doesn’t connect, you might want to check your micro-usb cable. Most of the time this is the reason why the connection doesn’t establish.
  5. Click PDA in Odin and find the contents of the I9100XWLSN_I9100OXXLS8_NEE.zip file you extracted earlier on. We’re looking for the following filename “I9100XWLSN_I9100XXMS2_I9100OXXLS8_HOME.tar“. Give it a few seconds to check the md5 for any corrupt data. Click 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.

Here’s a quick tip – I highly suggest doing a Factory Reset once you’re done updating your firmware even if you’re coming from a previous firmware version for performance sake.

  • sean from Philippines

    wow! hmmm a bit nervous, should i update now or wait for the other..

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

      Hey Sean. Why don’t you give this update a try? :)

  • http://twitter.com/rye_ong15 Rye Ong

    When do we use the Samsung Kies software? It was only mentioned that we need to have it installed, but the steps do not include actually using it. Thanks!

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

      Hi There. Samsung Kies should just be installed as it will provide driver support (communication software between your computer and the Galaxy S2). You don’t need to use it :)

  • http://www.facebook.com/ihatedc Lyndon Faderagao

    yeaahhhh…mine i recve from OTA…hehe…my battery is doing good..

    • Alfred

      Yep agreed. Battery performance is doing good for me too! Or maybe is it me. It seems little better :)

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

        It’s definitely better than the dreadful XWLSD Firmware ;)

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

      Hi Lyndon! Nice to see you dude! What was your previous firmware version prior to updating it via Kies? And yes, battery life is surely better on the XWLSN Firmware :)

      • http://www.facebook.com/ihatedc Lyndon Faderagao

        im from xwlsj…and last week i recve ota updte…i bcame xwlsn…

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

          You’re one of the lucky few ;)

  • Kurosaki

    hello Wiredmash. please help me, i can’t connect to kies on my computer after ive install this rom,,, please help, i need to restore my file back from the backup file,,, :(

    • Kurosaki

      btw it says (samsung kies) that “this device is not supported by kies 2.0. make sure that your device is supported and try again.” what now,,,,,?

      • Kurosaki

        still no reply,,,,, :(

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

          Hi Kurosaki. I apologize for the late reply. Have you tried enabling USB Debugging Mode on your Samsung Galaxy S2? :)

          • Kurosaki

            well its alright man, dont worry. ^_^ well,,,,, i already did what you told me,,, but it doesnt work too,,, :(( what now? should and can i flash the same rom again~?

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

            It might be an issue with your Galaxy S2′s hardware not being associated with the recent update as it’s not the exact firmware for your i9100. Where are you based? You can try checking out http://www.sammobile.com regularly to see if there’s an update for your region :)

          • Kurosaki

            Well Sad To Say,,, We Don’t Have Any Official Update From Samsung Here In Brunei,,,,, That Why I’m Manually Updated It Via Odin,,,, Well Just To Let You Know That I Have NO Problem At All With The Previous Update(XWLSJ) So Can I Install That Rom Again When I Already Install This Rom?(XWLSN) Really NEED Your Feedback, Thank You.

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

            Hi Kurosaki. Sure you can install the XWLSJ Firmware again. Just flash it via Odin :)

          • Kurosaki

            THANK YOU Man, Really Appreciate It ^_^ But I’m Curious, Can I Install This Rom One More Time??

          • Kurosaki

            Jose?

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

            Yes, you can very well install the firmware one more time :)

          • Kurosaki

            Hee Okay, THANKS Again Jose ;)

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

            Anytime Kurosaki :)

  • Mir

    Hi Jose. Just 1 question, does it make any difference if I am on XWLSJ or XWLSN but ultimately I want to install a custom ROM…will it have any performance or any difference ?

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

      Hi Mir. Nice to see you again. Well, the XWLSN Firmware is the latest firmware version so I do recommend updating to it. In regards to Custom ROMs, you need to root your Galaxy S2 first. Here’s a guide flashing the Siyah Kernel to root your phone – http://www.wiredmash.com/how-to-root-samsung-galaxy-s2-i9100-jelly-bean-4-1-2/

      • Mir

        My question actually was that lets say I am on XWLSJ and I’ll be installing a Custom Rom. So, what I am asking it will it make any performance difference if I first update to XWLSN & then install a Custom Rom ?

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

          Regardless of which firmware you currently have installed, the Custom ROM would be installed as a new operating system on your Galaxy S2 i9100, thus, you would need to do a Wipe Partition and a Wipe Cache after. Check this guide and video of me installing Cyanogenmod 10.1 on the Galaxy S2. You’ll get a better understanding of how it works – http://www.wiredmash.com/how-to-install-a-custom-rom-on-samsung-galaxy-s2-i9100/

          Hope this helps :)

  • rbrt

    Help…im stucked on almost an hour to this process what should i do?

    • rbrt

      okay…so i figured out why im stucked on to that…wrong .tar file has been set to pda..anyways i already clicked the right one but still i have the same error as the screenshot above..also should i use the original cable as the samsung provided to me?..cause im using a different cable..and the box in the upper left did not prompt indicating that the update is already taking in place.. thanks! :)

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

        Hi rbrt. I suggest you change your micro-USB Cable. It usually is the cause for the flashing process to fail. :) Let me know how it goes.

        • rbrt

          And im done flashing..it works fine and also the battery! Thanks again..til the next update ( hope it will be 4.2 ) :) btw replacing the cable is the solution to this even if it is not a samsung cable. Salamat :)

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

            Great! You’re welcome mate :)

  • Aaron

    hey wiredmash, i noticed something when i upgraded from XWLSJ to XWLSN. the RAM decreased from 800+ to 782mb. can you verify this? thanks so much!

    • Alfred

      Did you flash Siyah’s Kernel? I only know that my ram dropped if the kernel was flashed. It’s a problem that Siyah trying to resolve. Didn’t notice any changes to my ram since I switch from J to N.

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

        Hi Alfred and Aaron. It most likely is the kernel who has used the additional RAM. Perhaps it has something to do with CWM and SuperSU?

  • John Sip

    Hey… does the latest version from taiwan ZSLSJ have the same performance like the XWLSN .. like having good battery performance as well.. ?? I’m from taiwan and wants one with chinese.. that why.. any idea??

    • John Sip

      I’m currently on ZSLPQ which is 4.0.4 for taiwan and its telling me there is an update to ZSLSJ 4.1.2 ..but i heard of many issues of ppl on 4.1.2 and having battery draining… i want to ask if i upgrade to ZSLSJ ..will the battery performance be good..?

      • John Sip

        Or.. another question .. does XWLSN support traditional chinese … the second language on the screenshot..

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

          Ni Hao John. I suggest you update it via Samsung Kies as it’s the right firmware for your Galaxy S2 :) In regards to battery performance issues, I believe that was on the XWLSD ;)

          • John Sip

            So will the battery performance will be bad?? Becaz i want to update it.. but don’t want thebattery draining issue.. do you think i should update it?

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

            There are no battery drain issues with the latest Samsung firmware builds except for the XWLSD build. I believe the ZSLSJ build is clear from that battery issue ;)

          • John Sip

            Ok jose.. i already flashed ZSLSJ on my s2.. and it seems to be going fine so far.. battery looking almost like XWLSN .. and plus the XWLSN is working well although i only used it for a day..

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

            That’s great John! :) Glad everything worked out fine for you.

          • John Sip

            Yeah.. I notice the ZSLSJ is released on mar 23 and XWLSN is released on mar 19

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

            I believe the ZSLSJ Build is basically the same as XWLSN except for a few additions such as the Chinese language.

          • John Sip

            Yup.. i guess its so too.. except the firmware for ZSLSJ is larger than the XWLSN..

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

            I guess it has something to do with the language pack ;)

          • John Sip

            do you use whatsapp..do you mind me adding your phone number..?

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

            Unfortunately, I don’t have WhatsApp. You can contact me on Facebook though – http://www.facebook.com/wiredmash

          • John Sip

            That’s the battery life for now.. i think you should have a little idea of what its saying right..;)

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

            Looks pretty good! :) Thank you for sharing.

          • John Sip

            Jose.. i got another better one here for today..

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

            That’s pretty good. You’re up early ;)

          • John Sip

            Yah.. because the released date for ZSLSJ and XWLSN are released on the same date..so i’m wondering if it has the same performance. .i already flashed XWLSN on my s2.. it went well.. battery performance not too bad.. but there is no traditional chinese supported.. i am wondering if i should flash it to ZSLSJ.. u don’t need to tell me how to flash.. i kno how to flash any firmware on my s2.. so.. do you think i should flash it toZSLSJ ? just that i hope it will be the will have same battery performance??

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

            Go ahead and flash the ZSLSJ Firmware as just like you said it includes the Chinese language. Anyway, they’re both similar. Give it a shot.

  • ANIRVAN

    Hey wired mash. .. which one is better. .. XWLSK OR XWLSN? WHAT IS THE DIFFERENCE BETWEEN TWO?

      Hi Sanjay. You can very well update it by following the guide above :)

      • sanjay

        hi jose, i have updated from ics to XWLSN .thnx a lot for you r guides. but im little disappointing for it doestn show the battery percentage and not working vibrate when i touch the back key and home key. any ideas?

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

          Hi Sanjay. You can enable the battery percentage by going into Settings > Display and tick “Display Battery Percentage”. And in regards to the capacitive touch buttons, you can enable hepatic touch in the Settings too :)

          • sanjay

            Hi jose I couldnt find the hepatic touch option in the settings.

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

            Check out Power Saving Settings ;) It should be there.

    Hi Jose. I have installed XWLSN and now it did connect to Kies. But it is not restoring my Calendar..!!! After 50% it asks which events to restore I selected “All events” then after reaching 97% it give an error saying “Stopped Loading Schedule”..!!! what can I do ?

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

      Hi Mir! Try uninstalling and installing Samsung Kies. If that doesn’t work try using a new micro-USB cable. Let me know how it goes.

      • Mir

        but I successfully restored Memo..!! So it shouldn’t be a USB cable problem..!! right !!

            That’s strange. Have you tried rebooting your phone? I am not quite an expert in this area as I store all my calender events with my Google Account.

          • Mir

            Kies successfully restored the Calendar…but the events are not there in my S2 S Planner …I just cant see any events restored on the device..!!!

    hi sir, i already flash this rom, and its all good but i got one problem when i try to take a pictures on camera in the dark place, the screen has black lines like an old tv screen going up and down,, i already wipe the data and cache but it still there,,, but when i was in a gingerbread rom it has no black lines in camera in dark place,

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

      Hi Kelvin. That’s quite strange. It might be an incompatibility issue with your camera. I suggest you reflash the Firmware (XWLSN). If it still like that I suggest you flash the XWLSJ Firmware instead. http://www.wiredmash.com/samsung-galaxy-s2-i9100-jelly-bean-4-1-2-xwlsj-firmware-march-2013/

      • kelvin

        thank you sir! i guess I’ll wait in future release of jelly bean. actually it shows the black lines clearly in the dark place and when you capture the image no blacklines and the image is ok, only in the screen display the black lines like a old tv screen going up and down, but in the light place my camera screen is ok…and when i was on gingerbread no lines in my camera screen. thank you sir!

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

          Hi Kelvin. That might be a hardware issue. It looks like your display is about to give up. Have you tried having it checked up at the closest Samsung Service Center?

    Hi Jose, I’ve been having a problem.. my phone got stuck on the black screen with the words “Samsung Galaxy s2″ and the yellow triangle on it. I tried flashing this rom using odin, but it says “FAIL” on odin. I don’t understand why :S Help would be greatly appreciated :)

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

      Hi Michael :) Do you have Samsung Kies installed? And try using a different micro-USB cable? It usually is the case ;)

      • Michael P

        I installed kies and changed the usb cable.. I live in australia, and i tried using the autralian rom, but it got stuck on the ‘NAND write start’. I looked it up and people say i have to use PIT or something.. i don’t know what’s wrong :/

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

          Try downloading all the different versions of Odin. PIT is a last resort according to my research. Which version of Odin are you currently using?

          • Michael P

            I’m running the latest version 3.07.. yea same here, but nothing else seems to be working.. would using an older version of odin possibly work?

      • jenni

        im afraid. what if it fail? what is the worst?

        • jenni

          oh and also i want to ask you . when you update how much does it consume your battery? as my battery is draining really fast. i sure will charge it full but just to make sure, i wanna know your battery level reduction. thx so much jose:))

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

            Hi Jenni. It consumes a lot of battery when updating a firmware as a number of processes are on-going. Nevertheless, if your firmware update fails via Odin, you can always try flashing again. Failure usually happens due to a bad micro-usb cable. :) Is your phone still under warranty?

          • jenni

            unfortunately no :( what if the battery die when flashing? can the phone just pretend like nothing happened and i can just turn it on again ? haha..

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

            Haha. I found that funny :p Well, I suggest you fully charge it to 100% just to be sure prior to flashing then you’ll be safe and sound.

    By installing through Odin the latest firmware, what languages do i get? Does it have all the European languages? Thank u in advance.

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

      Hi Theo. It will depend on which version of the firmware you are flashing. For instance if you flash the Nordic XWLSN Firmware I believe most European languages are there. Which one are you particularly looking at?

      • Theo

        Greek

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

          I believe there’s Greek. I can recognize a few Greek characters in the language options ;)

      Hi Haitham. You can very well update it, however, you’ll lose NFC capabilities. There’s a Jelly Bean 4.1.2 Update for your GT-i9100G. Check out http://www.sammobile.com/firmwares and do a search for i9100G :) Hope this helps.

  • ecnarfi

    Thanks very much for this guide. I’d been unsure whether to upgrade mine and am very glad I did. XWLSN seems so much smoother and more stable that ICS was :)

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

      Great ecnarfi! It definitely is a lot smoother compared to ICS :)

    has it been launched for India?….I am thinking of upgrading it again, just been on this for a few days you know

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

      Hi Shahid. Yes, it’s been launched in India already specifically the XWLSN Firmware. Did you buy your Galaxy S2 from India? Nevertheless, head over to http://www.sammobile.com/firmwares and search for i9100 and look for the XWLSN for India :D Hope this helps.

  • http://www.facebook.com/shahidmukadam Shahid Mukadam

    Isnt the India update the XWLSK not for India. I have anyways tried to install it lets see

  • Niraj Shah

    Hi, I have S2 GT I9100 – with Jelly bean4.1.2 XWLSK which i loaded few days ago. The problem is that this update has screwed the battery life royally. I wanted to know will the update as per your instructions improve the battery life? and is this safe??

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

      Hi Niraj. The XWLSN has pretty much solved the battery life issue :) You can give it a go if I were you :)

  • Mervin

    Does it have multiwindow feature??

    SMART STAY IS NOT WORKING IN XWLSN…. WHAT TO DO?

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

      Hi again. How’s it not working exactly?

      • ANIRVAN BANERJEE

        THOUGH I AM LOOKING AT THE SCREEN, ITS GETTING TURNED OFF. NO USE OF SMART STAY…!!! WHAT IS UR EXPERIENCE?

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

          Are you in a brightly lit environment? Personally, I have turned off motion. It drains the battery slightly plus I don’t have much use of it. :)

  • ANIRVAN BANERJEE

    FOR INDIA IT IS XWLSK.. NOT XWLSN…

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

      I might have been mistaken. Nevertheless, does Smartstay work with the XWLSK build?

      • ANIRVAN BANERJEE

        NOPS… SMART STAY IS USELESS….

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

          I agree with you. Time to disable it ;)

  • grant h

    Hi jose. Thanks for the awesome guide. I have abit of a problem though.I had another jb firmware on my handset.But decided to try this xwlsn to fix the battery draining issues.Even though I flashed the firmware successfully, it indicates in my settings menu that I am running baseband xxls8 and build number xxms1. Im pretty sure its the exact same firmware I had before. Please help

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

      Hi Grant. You’re welcome. :) Check out the build number. It should read as XWLSN. Actually, the XWLS8, XWLSD, XWLSJ and XWLSN share a few things. If you don’t feel satisfied you can always try reflashing the XWLSN again. You can do a factory reset too :)

  • Eman

    nice article. btw my screen didn’t get stuck at the samsung logo, but rather, it continuse to upgrade (optimizing apps 1 of 121). do i still need to do wipe cache?

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

      Hi Eman. Glad you liked my guide :) Nevertheless, does it always optimize the apps after every reboot? You can try doing a factory reset if the problem continues to persist. :)

      • Eman

        it seems fine, wi fi’s connecting, no problem with the camera and the gallery.. the only problem i’m having is that it freezes whenever i connect my phone to my computer, and also, i’m having a hard time sorting my playlist. it won’t detect files located in my SD card. and it won’t let me move files/folders using the built-in files manager for sII. :(

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

          Hi Eman. I suggest you make a backup of your files and do a factory reset. I think it will solve most issues :)

          • Eman

            once i reset it to factory settings, do i need to do all of these steps again?

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

            Nope, you will just have to re download your Apps and setup your phone again. You can backup the list of Apps you downloaded by synchronizing it with your Google Account too so that it will automatically download when you setup your phone again :)

          • Eman

            once i do the reset, do i need to do all of these steps again? or do i need to update it first to ice cream then to jellybean?

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

            If it’s on Jelly Bean, doing a factory reset won’t downgrade your phone :)

  • arya

    is factory reset needed when upgrading from gingerbread 2.3.4 to jellybean. how to do factory reset?
    and does ZSLSE have multiwindow?
    i have galaxy s2 i9100 variant bought in indonesia. does it mean i have the international one and can flash via odin? just wanna make sure before upgrade. thank you:))

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

      Hi Arya. Firstly, yes you got a GT-i9100 which is the international variant :) You can make sure by going to Settings > About Phone. And no you don’t need to do a factory reset if you’re upgrading from Gingerbread or ICS to Jelly Bean as you are just simply updating your operating system. :)

      Unfortunately, none of Samsung’s Official Firmware builds have multi-window support. They don’t plan on putting it. However, you can root your Samsung Galaxy S2 and install the NeatROM Lite which has multi-window support :)

      • arya

        oh i see! thanks!
        if i use this xwlsn version. can i see other language characters in my phone?
        i want english as my phone language but i want it shows chinese, korean, japanese, russian, etc characters . now in my gbread languange settings, it only contains english and korean, but i can see japanese chinese russian and other language characters.

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

          You’re welcome Arya. Yes, most likely :)

  • Eman

    once i do factory reset to fix problems, do i need to do all of these steps again?

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

      What steps are talking about?

      • Eman

        these steps to get to 4.1.2.. the procedures mentioned in this article

        • Eman

          btw, regarding the playlist for my musicplayer (default one for S2), mp3s needs to be in the phone’s memory, not the SD’s.. i don’t know if it’s just for my phone, but if the files where in my SD, music player can’t locate it.

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

            I believe a factory reset would solve everything :)

          • Eman

            actually it didn’t. after i reset my phone to it’s original settings same problem shows up for my gallery. it won’t load the files, it’s showing the folders but without an image, just blank, gray boxes.. when i tried to open my pictures using file manager (default one) still, it won’t open up. i’ll try removing the SD then putting it back later, let’s see if that helps. do you think i need to do wipe cache?

          • Eman

            it’s not working, that’s the only problem i’m having, it seems that whatever app i’m tryin’ to use to open images, it won’t load. i can’t upload pictures to facebook, can’t upload to instagram.. what’s the resolve? i use my phone mostly for taking/uploading pictures. help me man. thanks

          • Eman

            back up files on a computer/laptop, format SD card via laptop, put back files in card. that should do the trick. thanks anyway

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

            And you read my mind ;)

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

            Hi Eman. Why don’t you backup all your stuff on the SD Card and format it? There might be an issue with the file structure of the SD Card.

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

          No ;) I mentioned it in my earlier replies to you.

  • Eman

    it freezes most of the time.. what do i need to do? i think it’s much slower now after the upgrade from ICS.. pictures in my gallery takes time to load, when i open application manager it takes time to load, whenever i open task manager it still takes time to load.. idk if it’s a good choice to switch to this OS.. it’s just way too slow..

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

      Do a factory reset. I must have said it half a dozen times already ;)

  • vaness

    hi jose i read the comments bellow .. which factory reset do you mean once we finished installed this jb? from settings – privacy? or the one you mentioned above (from recovery mode)? what is wipe partition? :o thx.

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

      Hi Vaness. Either of the options you mentioned ;) I prefer the one in Recovery Mode though ;)

      • vaness

        are you using this xwlsn version ?

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

          At the moment I am using the NeatROM Lite which is based on the XWLSN Firmware :)

          • Jay-Ar Ochoa Abad

            if i do factory reset in recovery,mwwla po ung root?

  • kelvin

    hi good pm sir, is it a bug when i put my vibrate level into zero and unchecked all vibrate settings including the haptic feedback but when I drag any application into homescreen it still vibrating even i turn off my phone it also vibrating, is it a bug or what??? thankyou ang looking forward to your thread… :)

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

      Hi Kelvin. I am not quite sure if that’s a bug. Try asking someone to call you? Does it vibrate too?

      • kelvin

        how about you sir is it vibrating too when you drag any application into homescreen and vibrate also when turn it off your phone? even though you set all vibrate settings into zero and unchecked the haptic feedback

        –>> i guess is normal sir because a friend of mine has S3 and i tried to set all vibrate into zero and unchecked haptic feedback and when i test to drag any application it still vibrate too,,, ehhe :)

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

          Hey Kelvin. I never noticed that ;) I guess it didn’t quite bother me. Nevertheless, it sounds like a bug for the Galaxy S3 and the Galaxy S2 even if one turns off all vibration settings.

  • james tan

    Thanks Pare! I followed your instructions and updated using XWLSN to JB! It went without a hitch. Thank you thank you!

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

      Hi James. Awesome! :) You’re welcome.

      • james tan

        hi Jose,
        after the upgrade, I noticed that swype doesn’t work too well at times. sometimes, Swype do not automatically insert spaces between words. at other times, it’s fine. Have youencounteredthis? (like this) Thanks.

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

          Hi James. Yes, I have encountered issues when it comes to Spaces and Predictive Text. I suggest you download the Jelly Bean Keyboard from the Play Store :)

          • james tan

            ok thanks.

            I just realized, my phone could no longer “see” flash drives plugged in using a usb adapter. also, everytime the phone is turned off and restsrted, the pictures in the picture frame are lost and I need to reassign pictures all over again.

            Which version of Windows are you running? Have you tried reinstalling Samsung Kies on your computer?

    I just wanted to say thanks! I upgraded my friend’s 9100 successffully using your guides: 2.3.3 (Stock) to XWLSN (Stock), then rooted with Siyah Kernel, then flashed with Neat Rom. Salamat!

      Hi Erwin. You’re welcome pare. :)

      • http://www.facebook.com/erwin.dominguez Erwin Dominguez

        Bro, I’ve been playing around with NeatRom. Have you noticed any bugs with: 1. WIFI and 2. Lock Screen Settings?

        1. WIFI, once I turn off the WIFI and turn it back on, it gets stuck. I eventually have to reboot the phone. Sometimes, it turns on but cannot detect the WIFI router.

        2. Settings>Lockscreen doesn’t have an option to change lockscreen shortcuts.

        I did a factory reset, but the problem still exists. Do you know if these bugs are only on NeatRom or are also in the XWLSN firmware?

        Thanks.

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

          Hey Erwin!

          1. I have yet to experience any WiFi Issues.
          2. Really? Can you send a screenshot of the Lock Screen settings page

          It might be bugs on either NeatROM or XWLSN. However, I didn’t notice any bugs on the XWLSN.

          By the way, there’s a new firmware from Samsung – XWLSS. Check it out at http://www.sammobile.com/firmwares

          • http://www.facebook.com/erwin.dominguez Erwin Dominguez

            Thanks for the reply bro. I resolved the issue with the Lock Screen, but still no luck with the WIFI issue. I tried Stock XWLSN, Neat Rom, Slim Bean Rom and still have the same problem. I’m giving up on JB for now, and plan on downgrading back to stock GB.

            Btw, will I have problems downgrading from Jellybean to Gingerbread via ODIN? I’ve been digging around and I’ve read somewhere that it is important that I have the .PIT file? Any help or info would be appreciate!

            Thanks!

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

            Hi Erwin. Have you tried accessing other WIFI Networks?

            Anyway, you don’t quite need the .PIT file from what I understand. If I were you, downgrade to at least ICS and not Gingerbread :)

  • Thom

    Sir, does it have philippines langugage?..

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

          Hi there. I suggest you root your phone (http://www.wiredmash.com/how-to-root-samsung-galaxy-s2-i9100-jelly-bean-4-1-2/), I am assuming it’s on Jelly Bean already and install Galaxy Sim Unlock from the Play Store.

            Hey there. ;) Don’t call me Sir, I have yet to be knighted by the Queen ;)

            The difference between the Lite and the Full is that the Full includes Samsung’s Apps.

            In regards to your battery life have you tried fully discharging your battery (until your phone shuts down) and charging your phone while it’s off?

      • yey

    Hi~

    My phone keep get stuck at the Samsung boot screen after I flash this rom. I had tried a Wipe Data (Factory Reset) and Wipe Cache Partition, but still same. Can you help me? Thanks~

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

      Hi Chua Yong Kian. What’s the exact model of your phone? Have you tried reflashing the Firmware? Let me know :)

      • Chua Yong Kian

        My phone model is GT-i9100, i already tried reflashing the Firmware but still same….

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

          Reflashing the firmware should have sorted out the problem immediately. Which firmware were you trying to flash? Have you tried the XWLSS? http://www.sammobile.com/firmwares

          • Chua Yong Kian

            Not yet, I will try later~ Thanks~

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

    Hi Jose,
    after upgrading, there seems to be a software update available when I do “check for updates” on settings. should I proceed? have you seen it? thanks.

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

      I believe that’s for the XWLSS Firmware :) You can give it a go :) Let me know how it goes with it.

      • james tan

        I updated this morning. I don’t know… didn’t notice any differences.

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

          Thanks for the update James. Perhaps a few bug fixes were part of the update :)

  • shifee

    Can I install this on my rooted phone without unrooting?

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

      Hi Shifee. Once you flash Samsung’s Official Firmware you will automatically unroot your phone ;)

    are there another download link from any link just not hotfile
    thank you

    i made a lot of misstakes my i-9100 has an oficial orange romania software 2. something :( so i ruted with CF Root File the instal some neeat rro 4.8.1 dont wanna start it is stack at the begining the i ruted with Siyah Kernel S2-v6.0beta5 TAR file and reinstal still no work. how i start from the begining to erase all and instal again ? can i ? i distroy my phone ?

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

      If it was Android 2.3 both the CF File and the Siyah Kernel will not work as they are intended for other versions. Don’t worry. I suggest you download the 4.1.2 Firmware here -http://www.hotfile.com/dl/224259632/83d4361/I9100XWLSU_I9100OROLS5_ORO.zip.html

      Flash it via Odin in the PDA field. Once you’re done flashing it, flash the Siyah Kernel ;)

  • Arthur Souza

    congratulations for the post, and I want to know if that rom of XWLSN with battery manager apps would have any difference… And does battery manager apps make any difference on the performance of the cel phone…

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

      Battery Manager Apps don’t make much of a difference. Just use the Power Saving options on the Samsung Galaxy S2 ;)

      • Arthur Souza

        right. another thing that I want to ask is about for a new update of my XWLSN. 7.73 MB it. I updated, and went to XWLSS. Do you think XWLSS is better than XWLSN or they are the same? Because when I used the cell phone for a day after the update, the battery went a little bit more faster.

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

          The newer update should be able to resolve a few bug fixes. XWLSS is pretty decent. ;) Give it a few days for the battery to “adjust” to the new firmware.

  • shiro

    hi jose i want to which the better firmware xwlsj or xwlsn ?plus what the difference between it
