I want to completely restore a jailbroken and unlocked iPhone 3G. I get the 1015 error. I have tried multiple programs and button patterns, but still get the error at the end of restoring When I first got it I automatically tried the iTunes restores without putting it into any "mode" which I believe messed it up. I can't get past the iTunes USB screen. Tiny Umbrella said Invalid, under device model. I don't care about restoring firmware from jailbreaks and such. TU only allows me to "exit recovery mode" but as of now my iPhone is inoperable.
