My iPhone 2G with 3.1.3 started acting up on me a couple of days ago and would get locked/ unjailbroken everytime i would hard reset it or turn the iPhone off. I would simply restore it to 3.1.3 firmware then jailbreak with redsn0w. But yesterday it would not let me restore the phone. I tried literally every firmware from 1.xx to 3.1.3 and would not restore. Now i get "Error (28)". Ive also tried restoring it on different computers/USB ports/ USB cables/different iTunes versions but nothing seems to work. Ive also tried using Ireb, Redsn0w, Blackra1n, Recboot, Spirit, iRecovery, winpwn, quickpwn, but I can't get out of this Error (28). Someone mentioned that if i got it into DFU mode then maybe i could clean the firmware from any corrupter restore and could get it back up. Does anyone know how to get into DFU mode from recovery mode, or better yet how to fix this Error (28)?? ANY help will be GREATLY appreciated....like seriously
