Do you have the BELL variant of Galaxy S III SGH-I747M, and find yourself jealous of owners of all the other variants who have been getting leaked Jelly Bean builds for their SGSIII devices? Your wait is over, as a leaked Jelly Bean build has appeared for the device.
The I747MVLALI2c build is based on Android 4.1.1, and is an internal Samsung leak for the BMC Region. It was posted to the forums by Senior Member AdamLange. Being a Samsung-created build, it’s running TouchWiz. Note that it’s in the form of an incremental update, and thus you need to have Samsung’s official latest I747MVLALH1 build already running on your device to be able to flash it.
More details can be found at the forum thread. XDA Senior Member mixxy has also provided us with a step-by-step tutorial for getting it up and running—including instructions on getting back to the latest stock ICS build if you are currently on a custom ROM._________
