Here’s the storyline.
You jailbreak your iPad.
Then, you find an app called Wi-Fi sync, where you can sync your iPad over Wi-Fi with your computer. This includes both an app from Cydia on your iPad AND it requires an app on your PC/Mac.
Then, you want to undo the jailbreak.
So you go into iTunes and click the Restore button.
It restores for the most part, but then, it hangs at the very end.
Now your iPad is in recovery mode, and you can’t restore it.
Well, as you might have thought, you need to uninstall Wi-Fi Sync!
Just download the file HERE (mac only) and run the uninstaller. After you uninstall, the restore should go perfectly.
