I recently updated to 5.0.1 after using a very successful ios4 jailbreak for months. I am now trying to jailbreak 5.0.1 using redsn0w 0.9.9b8, but having serious issues. After jailbreaking using this method cydia is blank and will not launch. I have tried jailbreaking multiple times to no avail. I have tried to restore and get the "device is not elligible for the requested build" error. I tried to fix this by deleting/reinstalling itunes and restart as well as fixing my host file by adding '220.127.116.11 gs.apple.com' and itunes itself will not restore to 5.0.1, as I get the same error message. Any ideas? Is there a way to completely wipe the phone and work from scratch without restoring?
