really could use some help here! 1) I downloaded 4.3.3 and updated my ipad 1G 3.2.2 (it was already jailbroken before). I did an update with tinyumbrella TSS server running in the BG. Installed fine, then after reboot screen went black and got stuck in DFU mode. 2) I installed iReb and attempted to hit fix recovery in tinyumbrella just produced some code and went back to DFU mode. 3) So I tried RECboot and that did not work either. 4)Then I re-jailbroke my ipad with redsn0w and after injection of code on reboot ipad went back into DFU mode. 5) Lastly, I tried sn0wbreeze custom ipsw, again injected code and on reboot went back into DFU mode. I'm at a lost right now, I was hoping someone could give some more suggestions before I do a complete restore to 4.3.5 and lose my JB. Please help! Question is it even possible to update unsigned code (ex. 4.3.3 or lower) without having SHSH files? Thanks for helping me!
