Hi, sorry if it's been asked or covered but after quite a lot of searching, trial and error I'm a but stuck. I'm not very familiar with jailbreaking and I'm learning as I'm going.. I'm trying to totally reset/unjailbreak an iphone 3G. Trying to just restore it in itunes gaves the 1015 error. When I got it, it was in showing the connect to itunes graphic on the screen so I didn't have any idea of previous settings etc but after some trial and error I've been able to restore it using redsn0w 0.9.6rc16, "iPhone1,2_4.2.1_8C148_Restore" and "iPhone3G_4.2.1_8C148_Custom.[iPhoneRock.Com]". That basically leaves it from what I can tell working better but still jailbroken and with Cydia installed. It's picked up by itunes and I then set it up as a new phone. If I then try to do a standard restore though in itunes it just goes back to error 1015, repeating the redsnow process gets it working again but with Cydia as above. In that state I can see: Model MB489B, Modem Firmware 06.15.00 I tried to use the redsn0w process and then at the restore stage use what appears to be a standard firmware instead of the 'custom' one but that didn't work either. Thanks for any help you can offer.
