I am trying to install/restore 4.3.3 on an iPad 2, which used to run 4.3.1. The SHSH blobs are saved with TU. Steps I have done: -download correct 4.3.3 firmware from the apple server -open the host file and remove gs.apple.com, then restart the computer -open TU 5.xx, (the newest), tick Set hosts to Cydia, then restart TU, after that start TSS server -open iTunes (10.3.1), set the iPad into DFU mode and do a Shift+Restore at some point itunes throws an error 20 (on Win7 x64), or an error 1013 (on XP 32 bit). From what I read, the 1013 error is to be expected, but I can't find a way to exit the recovery loop. The fixrecovery43 from the TU website doesn't help, as on Win7 it crashes immidiately and on XP it closes midway through the recovery process (after it has discovered the iPad in DFU mode) and TU's fix recovery tool doesn't help either. Are there any other steps to be taken? At the moment, I have given up and am now installing 4.3.4, so that the iPad 2 can at least be used. I realize that there are lot's of threads regarding this topic and I have read most of them, but to no avail.
