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?

"Try googling ""host file iphone"" had exact same error, and changing the host file fixed it for me.

But does sound like charging port."

I had my Iphone 5 screen apple logo blinking when It was connected to charger, I tried to restore using I Tunes, then it said error 4005.... what I did is simply I removed and changed batteries. I bought it on e bay with 6 dollars. and it worked. It is very easy to replace... so if you have the same problem just change the battery

"Dear Brian,

any luck finding an solution? I started with an error 21, replaced the battery and now getting the same error 4005. Also only getting into DFU mode and nothing else.

Thanks for any suggestions. Bye."

Never had any luck. Wound up selling phone for parts.
