lazy as i am i did a very "smart" thing : updated my ipad from 4.3.5 to 5.01 directly with redsn0w.
did not work well :-(
I am stuck with the logo in loop,
I did get manage to DFU with tinyumbrella but when i restore i get error 100x, 200x (i did follow somehow the tutorial TUTORIAL - Failsafe method to restore the current version of IOS )
i tried to jailbreak again with 4.3.5 or 5.01, the jailbreak starts but does not go very far (stop either at the pinneapple or at the bootscript).
Tried sn0wbreeze also without much result.
Any helpful idea ?
