Error 4005 Wont boot up but shows up in Itunes (DFU)
My Wife's iPhone 4 up and quit a few weeks ago. No signs of life on the charger or in iTunes. The dock connector was pretty corroded so I replaced that and the battery with no results. If I put it in DFU mode , it will show up in iTunes but gives me an error 4005 when trying to restore. I metered the charging fuses on the logic board and they seem OK. I'm guessing that would leave the charging IC ? Or am I looking at something else on the Logic Board as the cause?
Brian, I am not yet convinced that this is a hardware error. This could be caused by your iPhone iCloud back up settings being turned on. It would be great if you could try with your iCloud back up turned off. You could also try this:
If iTunes is open, exit iTunes
Disconnect iPhone from computer USB
Click Start menu on desktop
Go to Control Panel
Go to Programs
Go to Programs and Features
Select Apple Mobile Device Support and click repair
Connect iPhone to computer USB (device should install automatically)
When prompted, click restore iPhone
OS should install now and restore factory settings
and see if it works. From here. Hope this helps, good luck.
