My Problem

Went to apple and they told me my motherboard was wrecked. I think it was Error 21.

My Fix

Replaced the battery and now works like new.

Apple Sucks. Thanks for nothing "Genius". They tried to sell me a new contract instead for fixing a very usable device for $25!

My Advice

DONT GOT THE APPLE STORE....DONT BUY APPLE if you are not rich or dont feel confident opening a phone for repair.

THANKS IFIXIT!
