Hi sorin229,
It sounds like you're seeing an error when trying to restore your iPad. When you see an error during the restore process, it's best to start by trying these suggestions:
"1. Update your Mac or PC
Update your Mac. Or if you have a PC, get updates from Microsoft. If you're using iTunes, make sure that you have the latest version of iTunes.
2. Plug your device directly into your computer
Plug your iPhone, iPad, or iPod directly into your computer's USB port (not into an attached keyboard or USB hub). Make sure that the cable is in good condition.
Make sure that your device is unlocked. If prompted, trust your device.
If you still see an error alert, try a different Apple USB cable or switch to a different USB port on your computer.
3. Restart your computer and your device
Turn off your computer, then turn it on again. Next, restart your device.
Learn how to restart your iPhone, restart your iPad, or restart your iPod touch.
4. Check your computer’s security software
You might need to update, change, or uninstall software that could be interfering with your computer's connection with iTunes.
5. Use a different computer
Update or restore your device on another computer that uses a different network."

Cheers!
