The Samsung Galaxy S2 has been around for two years already and it has been updated from Gingerbread to Ice Cream Sandwich early 2012. A few months after, Google released their latest sweet, Jelly Bean. Samsung later promised that the Galaxy S2 will be updated to Jelly Bean without giving an exact date on the release. There was a leaked build of Jelly Bean firmware floating around, however, a number of bugs accompanied with it.
A week ago, Samsung officially released the Jelly Bean (4.1.2) Firmware for the Galaxy S2 i9100 (International Version) to two selected countries, Spain and China. Both firmwares are compatible to most i9100 devices, thus, if you purchased an unlocked Galaxy S2 i9100 from another country it would work flawlessly with Spain’s Jelly Bean firmware.
- Updated TouchWiz User Interface – Similar to Galaxy S3 and Note 2 (Smoother Transitions – Project Butter)
- Added Battery Percentage at Notifications Bar
- Added Smart Stay
- Improved Lock Screen – Custom Apps, Weather and News Stream
- New Galaxy S3 and Note 2 Widgets
- Added Notification Settings Shortcut Drawer
Prior to using the Official Firmware from Samsung, I was using several custom ROMs and Kernels including Cyanogenmod 10 and SuperNexus. The battrey life on some ROMs were horrific only lasting a few hours, however, with the official firmware I seem to have noticed better battery life especially when I am using it over WiFi and Cellular Data.
I’ll be using the Official Samsung Jelly Bean Firmware for the next couple of weeks and if I am satisfied with it, I’ll continue using it as my daily driver. I’ll wait for my region’s firmware to come out and that’s when I’ll flash my Galaxy S2 again.
How-to Guide: Update to Jelly Bean 4.12 Firmware on Samsung Galaxy S2 i9100
So you’ve got an aging Samsung Galaxy S2 with Ice Cream Sandwich installed and you can’t wait for the official firmware for your region and country? Here’s a quick guide in obtaining the officially Jelly Bean 4.1.2 Firmware for the Samsung Galaxy S2:
Note: This won’t work on AT&T, T-Mobile, Verizon and Sprint versions of the Samsung Galaxy S2. This works only on the international version.
- Download the Spanish Firmware (I9100XWLS8) V 4.1.2 (Jelly Bean) and extract to a folder.
- Download Odin and run it. It’s best that you have Samsung Kies already installed as this will provide communication between your Galaxy S2 and your computer.
- Power Off your Galaxy S2 i9100 and set it in Download Mode by pressing Volume Down + Menu Button + Power Button for 10 seconds.
- Once in Download Mode, connect your Micro-USB cable to your computer and press Volume Up to activate Download Mode. A yellow box will appear in Odin signifying a successful connection.
- Click PDA in Odin and find the contents of the I9100XWLS8 zip file you extracted before. We’re looking for the following filename “I9100XWLS8_I9100XXLS8_I9100FOPLS3_HOME.tar“. Press Start.
- 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 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.
