    I have a Tmobile Samsung Galaxy s3 T999. I heard you can root the phone to 4.2.2 so I tried to do that, but it failed and now my phone is stuck saying firmware upgrade encountered an issue. Please select recovery mode in Kies & try again. but I dont see this phone on Kies and my phone doesn't have a s/n number on the back to look up the firmware. Can someone help me. I tried doing hold the volume up, home, and power button, but it just goes back to that message.
