Crystal, u seem like the guy to ask. I have the same problem as this and have followed the steps but i was on official 5.0.1 with no signal and have used the official 4.1 to downgrade, i didn't get the 1015 error code and i've tried to jailbreak and deactivate with redsn0w but its not deactivating, i'm just getting the plug into itunes screen, any ideas??
Are you getting the plug into Itunes screen with slide to unlock at the bottom?
