6. iTunes has detected iPad in recovery mode. You must restore this iPad before it can be used with iTunes.

7. Select "Restore iPad"...

Note:

1. Data will be lost if you do not have backup

2. You must follow step 1 to step 4 VERY CLOSELY.

3. Repeat the process if necessary.

If you restore with a computer that was never synced with the device, you will be able to unlock the device for use and remove the passcode, but your data will be lost.

You may have to force iPad into Recovery Mode.
