why there are Roms if it can't be installed on s4 i337 AT&T because of its bootloader issues. I am confused please tell me about it. I'm a complete newbie.
There are other versions of the s4 (sgh-i337m) that use the same hardware as the AT&T s4 that do not have a locked boot loader.
Some sgh-i337 phones have not been updated beyond 4.2.2 so they will not have a locked boot loader.
