My ipad 2 is running 5.1.1. I have a custom IPSW and I would like to put it into PWNED DFU, but redsn0w says that the iPad 2 is not supported for that feature yet. How can I put my ipad into PWNED DFU mode? I would like to restore (I stitched my 5.1.1 blobs with the 5.1.1 firmware). When I try to restore without doing this PWNED DFU I get error 11 in iTunes. Thank you very much!
