There is a way though so make sure you follow these instructions carefully:
1. Hold the home and power buttons down together
2. The Apple logo should disappear from your screen
3. After a couple of minutes it should reappear – when it does, release the buttons
4. Quickly hold them both down again until your device goes off
5. Plug the USB cable into your computer (not to your device yet)
6. Hold the Home button down and plug the cable to your device
7. When you see the Connect to iTunes screen, release the button
8. iTunes will open and the Device in Recovery message will appear
Click on Restore
