I bought a used ipad jailbroken on 3.2
since i want to have multitasking and can wait to have the jailbreak solution running properly, i decided to restore to factory setting and upgrade it.
BUT: when i select from the menu setting erase data and contents
the ipad is now for the past 3 hours loading on the apple logo whatever...
i tried to press and hold for 10 sec the 2 buttons to reboot it.
it does reboot but come back to the same screen...
when plugg to the macbook with itunes, the ipad do not appear...
Every few minute it reboots by itself...ending up on the apple logo loading.
