First off, you cannot restore that 3G iPad to anything but 5.0.1 because it's a 3G version and you can no longer downgrade to any 4.x version, even with saved SHSH blobs.
Second, if you'd read through the posts on this forum, you'd have realized that, and learned that you should never attempt to restore a JB'd iPad the way you tried.
Lastly, if you had bothered to read the rules, along with the various threads in this forum, you would have seen that this forum does NOT support or condone piracy or those that do piracy by installing apps that enable piracy. In other words, it serves you right that you had troubles. Piracy is not only against forum policy, it is illegal! Don't be a pirate!
