can't restore iPhone, stuck on apple logo...
I have a iPhone 4 and was working fine until today, it suddenly switched itself off and I can't turn on unless plugged in to a computer or charger.
It will stay stuck on the apple logo no matter what, and switch itself off after a few seconds.
It is currently in DFU mode and I have tried restoring my iPhone on itunes, when it gets to "Preparing iPhone for restoring" the iPhone switches off instantly and I get the error "the iphone could not be restored...(2001)"
I've tried this 4 times and it always happens.
The iPhone switches off immediately when un plugged....
What should I do, what could be the problem? Should I take to repair??
iPhone 4, iOS 7.1.2
