Yesterday I turned on my iPad and got the connect to itunes logo…I was a little freaked, but plugged her in to my workstation. I got a message that the ios 4.2 beta was expired and I need to update (yes, I AM a member of the Apple Developer Program).
I download the latest ios sdk, and tried to update via iTunes 10 using the iPad1,1_4.2_8C5101c ipsw . The update failed and I went into restore mode. Forgetting that downgrades are not supported, I tried to the default restore (3.2. something). Now I got an error 1015 on update… So next I restored the same ispw using iTunes again. Next I got an activation error stating the device was not registered in the developer program and to register the deviceid via the developers provision portal. I tried to go back to restore/DFU mode using the normal means (home & sleep button,etc), but it would not re-enter restore mode….it would go straight to the connect to iTunes screen. Once I connected back to iTunes, I got the same activation error again, with no way to get my deviceid from iTunes!
