i have a iPhone 3g that had 3.1.3 running jailbroken(redsn0w) and fully unlocked. I recently decided to upgrade the software to 4.2.1, I believe when i upgraded it also changed my baseband it one that cannot be unlocked by ultrasn0w. So I decided to try using PwnageTool to create a custom .ipsw to upgrade the baseband to 06.15.00 via this guide: http://www.ihackintosh.com/2010/11/...band-06-15-00-with-pwnagetool-unlock-edition/
Once I did this the iPhone stopped booting. It was stuck in recovery mode, I tried rejailbreaking, not jailbreaking, old ipsw's. I tried using Irecovery but kept saying image not found, same the reb00t. Please Help, I really need my phone back!
