Before you proceed with the installation, do note that this is a leaked internal testing build, and not the final release. Therefore, it might contain some quirks that have yet to be ironed out. That said, if you just can’t wait till the final release is out (we can’t), here’s how to get it up and running on your Galaxy S III.

Disclaimer: Please follow this guide at your own risk. AddictiveTips will not be liable if your device gets damaged or bricked during the process.


  • International GSM Galaxy S III I9300. Do NOT attempt to flash it to any other variant of the S III.
  • Samsung USB drivers
  • (https://hotfile.com/dl/223564134/4017cbe/I9300XXUFME3_I9300OJKFME1_ILO.zip.html) Leaked Android 4.2.2 XXUFME3 ROM for Galaxy S III
  • Odin 3.04 (included in the above file)


  1. Take a backup of any data that you might need in case you later need to do a factory reset. This includes any data you might have on your internal SD card.
  2. Download the ROM’s package and extract the contents of the downloaded zip file to your computer.
  3. Download and install Samsung’s USB drivers, if they aren’t already installed.
  4. Power your phone off and boot it into download mode by holding Home and Volume-down buttons while powering it back on.
  5. Launch Odin on your computer and connect your phone to it via USB. You should get a blue indicator sign on Odin.
  6. Click ‘PDA’ in Odin and select the I9300XXUFME3_I9300OJKFME1_HOME.tar.md5 file.
  7. Leave everything as it is, and especially make sure that Re-Partition is unchecked.
  8. Click ‘Start’ to begin flashing, and wait for the process to finish.

You should now have the latest leaked Android 4.2.2 Jelly Bean firmware up and running on your S III.

In case there are any issues like bootloops or force-closes when you reboot your phone after flashing the firmware, reboot your phone into recovery by powering it off and then powering it back on while keeping the Home and Volume-up keys pressed, perform a wipe data/factory reset, and reboot the phone. This WILL delete all your apps, data and internal SD card contents, but your phone should boot and work fine after that. For this reason, taking a backup before flashing anything like this is extremely important.

  1. In other sad news, the AT&T S3 is still stuck on 4.1.1 while every other carrier has already received the 4.1.2 with premium update…

    • Smart Stay isn’t mentioned in the above list; it’s Smart Switch that’s there. =) Regarding driving mode, it was listed in the new and improved features at the source (the SamMobile link provided above). Likely improved/updated from the previous version.
