If you are on a Jailbroken/unlocked iPhone, and have tried to upgrade your firmware to 2.0 or 2.0.1 or to any of 2.x versions, you might have faced DFU errors like 1604, 1602, 1601 or error 6, 1, 2 few times. So many users who have upgraded to 2.x by mistake have just got stuck with iPhone in recovery mode. Here are few fixes which has been shared by BigBoss.

• Problem: I cant restore my custom firmware. I just get error 6, 1, 2, (something low).
  Solution: This has multiple causes. Generally, you are not in DFU mode. See DFU guide. Winpwn solution after ruling out the above: Delete the device file (x12220000_4_Recovery.ipsw) in your iTunes folder. (Search for the file). This can also be caused by using the incorrect firmware image (a 3g on a 2g for example).
