I'm still a little lost as to what you are trying to do. So please answer these questions specifically:
1) Right now, In normal mode (not DFU) does your iPad work fine when you have it disconnected from iTunes?
2) Again, not in DFU mode, when plugged in to iTunes, does your iPad sync fine and can you do "transfer purchases" and backups?
3) if no to either question, please tell what error codes you are getting. Again, this is in normal mode, not in DFU.
