I need to take my AT&T Galaxy S4 I337 to my AT&T store to switch it for a new one because the volume buttons are sticky and don't click properly. I flashed back to stock I337UCUAMDB with ODIN using the files from this thread:
I was running the GOLDENEYE 10 ROM which uses the international Samsung ROM running Android 4.3 and is modded to work on the I337. I put the phone into download mode and successfully flashed the phone but the phone does not get past the AT&T boot screen. I successfully flashed the phone again and I got the same result. I am suspecting that there might be an issue flashing the stock AT&T firmware while running an international ROM. I would like to know how I can flash back to any of the stock AT&T firmwares so that I can return my phone without voiding my warranty.
Also, I would like to know if it is possible to use the Triangle Away app on the I337 to reset the flash counter. The XDA thread for this app says that you must unlock the bootloader to use this app for the I337. I am not familiar with how to unlock the bootloader for this device. Any help with resetting the flash counter would be much appreciated.
