itunes error 9, 21...what are my options?

I am very sorry about the extremely long description but I wanted to give the full story.

About two months ago I happened upon 2 broken iPhone 3G' had a cracked screen and broken LCD and the other kept giving error 23 when restoring so was completely useless. See this thread on hackint0sh (

I took the display assembly out of the iphone with the restoring issue and installed it in the other iPhone. Everything seemed to work perfectly. However after a few days it spontaneously entered a reboot loop...often just ending up on a whit screen. When I repeatedly rebooted it, it eventually booted up normally. So I restored a few more times (it gave me many errors but I persisted (21 was common I think)) and eventually these issues stopped...until about two weeks ago.

Every once in a while it decided to go on a reboot loop but until today I had no problem just holding home and sleep a few times to eventually get it back to normal.

Today it entered a very familiar reboot loop and I just cant get it out. Errors 9 and 21 are very common when restoring. There are few others which I will edit this with. I have tried dfu and regular restore mode countless times.

So basically I have still got the carcass of the other broken iphone mentioned above.

Is there any way I could use the parts which are still useful to bring this phone back to life.

Again sorry for the extreme length of the question. I would really sincerely appreciate any help.

Thanks in advance,


edit: I can post itunes restore logs if that would help

Thank you vey much for your help...I will try a few things with error 9/ 21 in mind and post back here.

Please do let me know about the error 23 repair. I live in Ireland so it would be very possible for me to send it there.


Follow my original link - most of your error codes are for USB... Take good lookat both cable ends and your dock. Then look at computer software/security/iTunes. It's a really good guide
