    Hi all

    i recently replaced the screen on my iphone 4.

    It all turned on fine and i was using it untill i let the battery run down and it died.

    then it started a load up loop. going to the apple logo then off again.

    so i plugged it into the computer and did a restore.

    in the restore i get error 21 :/

    sounds like you have to change your source from Cydia to Apple

    was it jailbroken?
