I'm comfortable flashing from odin or recovery.
Thanks in advance guys.
A friend has been having issues with reception on his GS3. He is on BMB1 while I am on BLK3 but I am on a 4.4 ROM and he's still using 4.1.2. Is there something he can safely upgrade to from BMB1? Is it limited by running JB or KK? I was reading somewhere about the GS3 modems file signature and that you can brick your phone if you flash the wrong one. We are both rooted running custom ROM's.
