To fix this issue, you must put your i pad into DFU Mode
Basically DFU (Device Firmware Upgrade) mode is not a restore mode or recovery mode. But it bypasses the current OS installed in your device and allows you to upgrade or downgrade your current I OS.
To fix iTunes error 21, you must put your iPhone into DFU mode using the following instructions:
Firstly you have to plug the "i Pad " to the computer and open the " iTunes".
Now put your i Pad device into "DFU" mode so that you will restore the device .
For putting the device into DFU mode by just follow the steps:
Turn "OFF" your "i Pad" and "HOLD" down power button for 3 sec.
After enter into "DFU" mode your "i Pad" screen goes blank and get pop up message in iTunes apps “Device in Recovery Mode".
After all these your iPhone device will start to restore back to the i OS firmware.
This process will take latest 10 minute for processing so never disturb or do any thing with device.
