Samsung Galaxy S2 Android Jelly Bean Update Done In 9 Moves!

Samsung Galaxy S2 i9100 owners can get the Jelly Bean 4.1.2 update that’s come out in China, Taiwan and Hong Kong. This update is called Android ZSLSE, and it comes without branding, but with Chinese language packs.

It’s not custom firmware, so there’s no changes, and no ClockworkMod.

This update gives Galaxy S2 owners Project Butter, as well as a new TouchWiz UI. There’s also S Cloud, a customisable lock screen, Pop-Up Play and Smart Stay. The update also offers 50GB of Dropbox storage, Google Now improvements, a few new home screens and an improved notification bar. This update is just for the i9100 international Samsung Galaxy S2, though.

You need to back up your Samsung Galaxy S2 before installing the update, and you also need to make sure that USB drivers are installed on your PC.

Head to Settings > Developer Options. Make sure that USB debugging is activated and that you have at least 80% battery. You also need an unlocked phone.
Remember, you’ll have to re-root your handset after the update, and that the update is undertaken entirely at your own risk.

Follow these steps to bump up to Android 4.1.2 Jelly Bean.

Step One: Download the ZSLSE official firmware for the Galaxy S2 and extract the zip file.

Step Two: Download ODIN v1.85, which you’ll need in order to install the XSLSE JB update.

Step Three: Turn your handset off and reboot it in Download Mode. To do this, press and hold Volume Down and Home, the tap the Power button until you see the Android robot with a triangle. Hit the Power button again to go into Download Mode.

Step Four: Launch ODIN on your PC and connect your phone to it while it’s still in Download Mode.

Step Five: When your phone is connected properly, you’ll see one of the ID:COM boxes turn yellow with the corresponding port number. This step might take a while.

Step Six: Choose the files that you want to flash or install; these can be found among the files you extracted in Step One.

Check the ‘PDA’ checkbox and select the ‘.tar’ or ‘.md5’ file.

Select the ‘Phone’ checkbox then choose the ‘MODEM’ file. If you don’t see such a file, skip this step.

Choose the ‘CSC’ checkbox and select the ‘CSC’ file. Again, ignore this step if you don’t see this file.

Click the ‘PIT’ checkbox and select the ‘.pit’ file. Skip this step if you don’t see this file.

Step Seven: In ODIN, enable the Auto Reboot and F. Reset Time options. If there’s also a Re-Partition choice, choose it if, and only if, you chose a ‘.pit’ file in Step Six.

Step Eight: Hit ODIN’s start button and you’ll start the installation. It should take a few minutes.

Step Nine: Once installation is done, your Galaxy S2 should reboot. When your home screen appears, disconnect the Samsung Galaxy S2 from your PC, and start using your new Jelly Bean 4.1 update!
