"3GS stuck on apple logo after GPS/WiFi replacement"에 답변I had this problem and overcame it. My 3gs wouldn't boot past the apple logo after I installed a new wifi/gps antenna. Tried DFU a couple times, but still wouldn't boot for me. I opened the phone back up, detached the 7 ribbons from the motherboard, inspected them to make sure they weren't damaged, and carefully, and securely, reattached them. Put the little guy back together real quick, and was able to boot normally and do a restore.
