If it does not get restored/resolved, it is a hardware failure.

New Error is 21 😠

Check Hosts file of computer. Is it redirecting iTunes away from Apple servers ?

I know this won't be re-assuring at all but I thought I'd add the extra info..... My 4s died back on the evening of Tuesday, July 9 and was giving the same error. So today is Friday and I was going to take a drive to the Apple store and have them look at it. I plugged it in to give it some charge and was having breakfast when I heard the familiar chirp announcing missed calls and messages. Somehow it seemed to rise from the dead and is still acting ok now, maybe three hours later. I didn't do anything special other than trying to hook it up to Itunes and confirm I could get to the restore optionby holding down the home button, which I did accomplish. I'll update this link if I learn anythng more.

I have the exact same problem.

The only differance is that when I plug in my phone to my computer, it won't pop up on itunes at all and it does not show up in my finder menu. I just want to try resoring it, but I can't even do that.

So frustrated at the moment.

Did you end up fixing your phone?

After my reply of July 12, I did hook up to my computer and do a backup, which I realized had been done when I last plugged my phone in prior to the crash. The phone has been ok since except for two instances. In both cases, I had set up to take a photo and then the phone spontaneously rebooted. After the reboots it was ok so I'm trying to hang on with this until I decide to do a replacement. We're eligible with our carrier now so we're strategizing about when. Wish I could offer more hope but that's all the info I have right now.

hey i read all comments on the nand error... i find a way to solution to my problem which was very hard to figure out.... i decide to test and clean all components on it doesnt work to me.... But i start connecting my connecters one by each day and i figure the problem.... it was the power connecter
