Hi, I did a search of other threads but couldn't find an answer. I was given a 16gig iphone 3g with a broken digitizer. I had it fixed but the phone had been jailbroken and unlocked using redsnow. It was on a 4.2.1 firmware. I wanted to restore it so that it was locked to original settings and I could use it to replace my 8g model. I connected it to my itunes and hit restore. I got stuck in the loop and was told there was a 1015 error. I followed this tutorial (http://www.youtube.com/watch?v=BVhx8XjXqz0&feature=BFa&list=FL__6HUYbpYWI&index=6) using Tiny Umbrella and installing a 4.1 (8B117) firmware. It worked, although there still seemed to be some traces from the jailbreak. When I tried to use the update in itunes the next time I plugged in, it got stuck in that 1015 error loop again. So, I'd like to be able to restore it cleanly so that the phone can be regularly updated ensuring apps continue to work. Does anyone know if I can do this or is this phone destined to only be good if I never update it in itunes? Thanks!
