Not restoring after replacement

So I had a iPhone 6 come in absolutely ebliterated no screen and damage to battery etc. I have replaced the carcus and added a front screen I understand that the Touch ID will never work again. There was no physical damage to the motherboard it wasn't bent or anything like that. I replaced the whole phone basically and it was looping, so I put it in recovery mode to restore it thinking that would work but kept getting error 4005. Now I can't get it out of recovery mode and it won't restore any one experienced this before and if so what was the solution? Thanks in advance
