I purchased an ATT Iphone 4 (with 5.1.1) off craigslist a few weeks ago and apparently it was tether jailbroken with GreenPoison. I proceeded to jailbreak it (untethered) with Redsnow 0.9.12b2 and it worked fine. Now I am in the process of trying to get it restored via Itunes to it's factory settings. I am using Redsnow to force it into DFU mode. When I restore using Itunes it hangs up on "restoring iphone software" - the bar stops after getting about half way. On the Iphone the apple logo and process bar freeze also. I have tried the following: 1. Using Tinyumbrella 2. Erased host file entries containing "gs.apple" 3. Edited host files using "#" 4. Used Mac and PC 5. Used 3 different USB cables 6. Restarted comps several times 7. Ensured Itunes was up to date 8. Delete .ipsw and re-downloaded via Itunes. I am getting error "14" every once in a while. Any help getting this phone to restore would be much appreciated!
