I have a jailbroken/unlocked iphone 3GS running ios 4.2.1 using redsn0w 0.9.6b5 and baseband 06.15. I did a reset to delete all the old data that my wife had on it. I am trying to restore it using itunes but it fails giving error code 1015. I looked at the log and found the errors below. I want to restore the phone to 4.2.1 and can then jailbreak it later. What can i do? I am really concerned that by doing the reset after the unlock I might have frozen the device and would not be able to restore it. I would appreciate any/all advice.
