iPad stuck in boot loop, unable to recover

[Heitor]

My iPad is stuck in a boot loop. I've tried DFU and recovery mode with no success. I get different errors: 1601, 1611, 2001, and still other ones. Apple's site recommends me to check the connection. But my iPod Touch is syncing normally, and I've been trying two cables. And I've been trying on a PC and on a MacBook.

When I google my problem, most of the links are about jailbroken iPads, but mine is not.

Any suggestion before resorting to service?

I have exactly the same problem. iPad appears to be dead and have spoken to Apple with no success. Very interested if anyone can help.
