Hi, I bought a galaxy s3 off ebay so I can swith to t mobile but I want to get it set up and working how I want before I actually make the switch. So I've been loading roms for 2 days and trying them out. I cant seem to delete files from the sd card when I use any rom but the stock rom. I tried KitKat, CM11, CM 10.2 CM 10.1 and custom stock (I think that's what its called). also when I use es file explorer, only some of the photos I have on the card are viewable and some appear as broken and cant be opened. But then when I go to the stock rom, they all work fine. Id really love to have a custom rom but I need to fix this problem first. Any ideas?
