Unable to restore iPhone 5 after it dropped I have dropped my iPhone 5 last night and since then its either been flashing the apple logo on and off or just stuck in recovery mode. I have tried restoring it, but I just get error 21 or error 2002. I have tried using reboots, holding the home button and the on/off button and nothing seem to work.

How can I restore the iPhone?
Error 21 indicates issues with the power source/battery, error 2002 usually is a connection problem. Given the fall your phone did, it's a safe guess that something broke or got disconnected on the inside.

It's probably best to go to your nearest Apple Retail Store (if this is an option), your vendor or a local iPhone repair shop. If you are used to fixing electronic devices yourself, you may also find instructions on ifixit.com (search for the error number).
