Help please, Reboot, restore loop.

Hi everyone, and thank you for reading my post, here is the problem:

One day i left my Ipad 2 CMDA A1397 without battery charge for 2 days, when I try to charge it, it starts on the restore scren (Itunes logo and USB Cable), i cant go from that screen even if I just turn off the ipad, it doesnt go anywhere, so i connect it to my Laptop, and try to restore it,

when the software is done extracting, the iPad restarts and then it goes into an apple logo with a gray bar below(everything normal), when its restoring, it just shuts down and an unknown error (9) appears on itunes, and after some time it goes again to restore screen, so i cant never fully restore my ipad.

I know error 9 its because a connection lost between ipad and itunes, and this is because the ipad restarts himself.

I've tried using other USB ports, in my windows 7 machine and in a XP virtual machine in the same computer, later i'll try in another computer.
I've also tried restoring from DFU mode, its the same in the middle of the restore process it just restarts and goes do DFU again.

What should i do about this problem, i dont have warranty anymore and i really need this iPad,


Thank You

 

I forgot to mention that I have done that, I chafed my iPad overnight, I don't think it's restarting because of the battery charge.

Thank you
