Hi MacRumors! I'm having an issue with my jailbroken iPhone: I was trying to restore (Unjailbreak) it, but iTunes gave me error 1015. I have tried tinyumbrella and Tinyumbrella (fix recovery) on Mac, but have had no luck. I also tried to downgrade to 4.3.4. and 4.3.3 to see if I could get it out of 1015. Naturally, I changed the Hosts file to allow this to work, but it still wouldn't boot. At the moment, I'm willing to try anything to get it to boot, jailbroken or not. If you need any more information from me, just say. Thanks!
