Just wondering if this problem was resolved, and if so how it was done?
I have the same problem essentially. I think I scrambled my Ipad 2 (not 3) when trying to use it to tether to my laptop using tetherMe app from cydia, and pulled the plug out mid-sync
Downloaded Tiny Umbrella and followed all the steps, however the box that your supposed to un-check was blocked out and already unchecked anyway.
I've updated my iTunes and iPad firmware to the latest (6.0.1) and went to restore and I forgot to put it in DFU mode. Now whenever I attempt to re-install it looks like it is about to be completed and then I get the Error - 1 message.
Have tried to re-do all steps, (and also tried to boot it out of recovery via tiny umbrella - which fails) I think the key issue from following the steps is that now I can't seem to access DFU mode either.
Have also tried to restore via a different laptop which also lead to the same problem so it must be related to the ipad, and not the settings on the computer?
Any help would be greatly appreciated.
(sorry if this is in the wrong thread, didn't want to re-post when this is very very similar to my circumstances (looks like we both went wrong when not puting in DFU mode)
The below is very worrying!!
