So my buddy has a 32gb 3GS and it was previously jailbroken on 5.1.1 absinthe.
Recently his phone has been loosing battery very very fast and also running hot. Then he found his phone loosing power even when it was plugged in. He then bought a replacement batter online and installed it. Didn't seem to work so he then restored it to factory settings. Now when trying to restore using iTunes he's getting the errors 1600 and 21. His phone won't turn on unless it's plugged into his PC and then it will light up showing the picture saying it needs to be plugged into iTunes.
Can any help? Is there any change of him being able to fix this?
