[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] designgears:
WARNING: <- read this for real

This will wipe your internal sdcard. This does contain bootloaders, flash at your own risk! This is for the I747 only! No one but you can be held responsible for your actions.

How to Root:

Flash CWM or TWRP with odin, boot into recovery and flash a SuperUser zip.

Other info:

This is considered beta software until it is officially pushed out by AT&T/Samsung. Leaks do NOT come with changelogs, so don't ask, no one knows. I won't be providing any other versions of this leak, use the oneclick exe or wait for someone else to build a cwm/twrp flashable.

FLAMING or TROLLING:

The thread will be closed and links deleted.
