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?
