Few days back we posted that the Jelly Bean 4.1.2 firmware for Galaxy S3 would be coming out soon, the update was expected to rollout through an OTA update in the first week of December. The firmware has been already leaked out, you can download and install the same on your device using the tutorial that we’re going to write today. One of the highlight of the Android 4.1.2 firmware is that it brings the Multi-Window feature to the device.
The Jelly Bean rollout for India has been already terminated due to bugs in the software, though I still don’t recommend anyone to update their devices with the unofficial firmware. The firmware build is I9300XXELK4 .
Features of the I9300XXELK4 Firmware
- Android 4.1.2 – JZO54K
- Multi-View (Multi Windows Multitasking, same as in Note II)
- Page Buddy
- Notification Panel (Notification Panel can now be customized)
- Smart Rotation (Screen Display adjusts to your angle of sightings)
- Continues Input in Samsung Keyboard (Like Swipe or Android 4.2 Keyboard)
- Paper Artist App (Same as in Note 2)
- New Gallery App (Same as in Note 2 –)
Backup everything that is stored on your device before proceeding with this tutorial. You can use our ADB Backup Guide or Nandroid Backup Guide (Root users) to back up everything that is stored on your device. Disable Kies, Antivirus Software, and Firewall as they can clutter in between the upgrading process.
Warning and Disclaimer
This is all development stuff and in this tutorial we’ll be flashing the file in order to make it work on your device, rooting and flashing stuff voids the warranty of the mobile phone but the warranty can be always retained by flashing the Stock ROM.
The SamMobile folks posted on their website that this is an odin flashable firmware that has been repackaged by them using the dump files, and if you flash this file on your device then it would increase the binary flash counter. The firmware will also change your device status to modified.
