AT&T rom on T-Mobile S3?

[vince2398]

I have an unlocked S3 for T-Mobile and want to use it on AT&T HSPA+ but when I do the phone is always running warm and battery drains. Is the fix for this to install an AT&T stock rom on it? Is that possible? Any help is appreciated. Thanks in advance.

You should continue to flash tmo ROMs only. The phone heating up should be an entirely different problem..

What ROM/kernel are you running? Are you over clocked? have you messed with voltage?

Just need a bit more info before we can help you. =)

I am running everything stock from TMobile, and the latest OTA update. I haven't tweaked anything yet. What is a good starting point to fixing this? Thanks again.
