Hi everyone. I've had my nice unlocked iPhone working . I had SummerBoard installed, and I've applied a theme. Also, I had patched SpringBoard and used a custom carrier logo. Then I've deinstalled SummerBoard (I haven't changed theme to default before that). Also, I've removed a custom carrier logo, chosen the stock AT&T one with Customize porgramm, then deleted patched SpringBoard file from springboard.app and uploaded the original one. After all that I've rebooted iPhone, but it was stuck at Apple logo. It comes again and again. My iPhone doesn't boot. Although, iTunes and iBrckr both see it normally. How I can solve this problem?
