http://forum.xda-developers.com – Hey, I flashed I9300 rom on my T999 and after it turned off, it never turned back on again. It won't turn on/ download mod/ recovery mode or vibrate. If I take the battery out and plug it in the PC, it LED turns red for a short period of time only. I did a little research and it was no help. Will a usb jig work? (HowTos)
