How to Manually Update Galaxy S2 GT I9100G to Official Android 4.1.2 Jelly Bean XWLSR OS
First on your computer you have to download the update file and Odin.
We will use Odin for flashing the update on your phone.
The download link for the update file is here.
Download Odin from here.
Extract the update file on your computer and then install Odin.
On the PC open Odin.
Turn off the handset.
Reboot it into download mode.
The download mode can be reached by pressing and holding the Volume Down, Center and Power buttons together.
While the device is in download mode, connect the same with the computer by using its USB cable.
Now, on Odin the ID:COM section should be yellow and the “added” message should be there.
If different, download Samsung KIES and install the proper drivers for your S2 and then repeat the procedure from above.
Up next, click on “PDA” and select the update file (the .tar one).
Click on “start” and in the end you should see the “pass” message displayed.
Unplug the USB cable as you are done.
If by using Odin you can’t complete the update, unplug the USB cord and turn off the phone. Then remove the battery and re-insert it. After 5 seconds turn it on again and try to re-do the steps from the beginning; everything should be working fine now. Also, if after using Odin you will get a boot loop, try to do the following:
Boot into recovery mode (press on Volume Up, Home and Power buttons).
From there wipe the system.
You can make a wipe by selecting “wipe data factory reset” and “wipe cache partition”.
Then, choose “+++go back+++” and “reboot system now”.
The first boot might take longer than usual; don’t panic there is nothing wrong with your S2.
Well, that’s all for now. You have updated your Samsung Galaxy S2 with the official Android 4.1.2 Jelly Bean XWLSR OS. Test the firmware and share your impressions with us and with other users who might want to apply this tutorial. Also, stay close as we will bring more guides suitable with your S2 in the coming days.
