How to Flash I9300XXELK4 on Galaxy S3 (Android JZO54K)
WARNING: This is a pre-released, leaked firmware that may have bugs and issues. It will change your device status to “Modified”. It’s been tested to work well though, but there are no guarantees. So, continue at your own risk.
Step 1: Download the flashable zip file: I9300XXELK4_I9300OJKELK5_ILO.zip
Step 2: Extract the downloaded zip file.
Step 3: Launch Odin 3.04 which is included in the download package.
Step 4: Now put your Galaxy S3 in download mode. To do this:
- Switch your phone off
- Press & hold Power + Home + Volume down buttons till you see a triangle and Android robot.
- Now press the Power button to confirm entering the download mode.
Step 5: Once your device is in download mode, connect it to the computer. (Odin should already be running, as per step 3)
You will now notice that one of the ID:COM boxes in Odin will turn yellow when you connect the phone. It may take some time, so be patient and do not proceed to next step till you see it (the box getting yellow).
Step 6: In Odin, click on “PDA” then browse and select I9300XXELK4_I9300OJKELK5_HOME.tar.md5 file. This file should be where you extracted the zip file in step 2 above.
Step 7: Now click on “Start” button to begin the process. Before this: In Odin options, you need to make sure that “re-partition” option is not selected while “Auto Reboot” and “F . Reset Time” options are selected.
Now sit back and wait as the ROM is flashed on your device. Your phone will reboot after the process is complete. Once you see the start screen, you can unplug it from the PC and start using it.
To confirm that the firmware has been installed, navigate to Settings > About to check the firmware version. Enjoy!
