  • Why can't I restore my jailbroken iPhone 4? I jailbroke my iphone 4 using redsn0w 0.9.10.b6. This was a semi tethered jailbreak and i have turned my phone on and off. I now want to completely remove the jailbreak by restoring my iphone. But iTunes brings up an error- 'firmware not compatible'. I was wondering how i can get past this? (by the way i'm trying to remove it because it no longer works when i download the jailbreak tool- as i deleted it ages ago)

  • What can I do to restore my Unlocked & Jailbroken iPhone 3g? I recently got the phone. I tried to erase everything on the phone while it was near death, and I think it died while doing so. It then went into recovery mode. I tried to put it into iTunes to restore it, but that keeps failing too. The phone has a custom firmware, and I have no idea where or how to get the firmware to properly restore the phone to. Any ideas?
