HELP!! My iphone has officially died.

[cakerbaker]

So, my iphone died the other day. What happened was it went dead while I was at work and when I went to plug it up at home, the charging symbol did not come on. All I got was a blank screen I went to my brothers house to restore it and nothing but a white screen for a few seconds and then right back to black... itunes didnt even recognize my phone and I got the error 21 after trying for 2 hours to restore it. I need some help soon, thanks!!

Have you tried holding menu button and power button at the same time?

Yes, with no luck though. I have had that happen in the past and it came right back on after I held those buttons down but didnt work this time.

A quick google of iPhone error codes:

21 usually means security software on the computer is interfering with the restore. Instructions from Apple are linked.

Also, try plugging into the wall charger for 2-4 hours, overnight if you can.
