Error 4013 after changing Logic Board (tried everything)
I have a working Iphone 5s with locked icloud and a bad iphone 5s that wont charge.
So I decided to take the logic board from the bad iphone 5s and put in the working iphone with the locked icloud. I cant restore it!
If I take the icloud locked logic board and put in either phones, phone turns on and works but if I take the other logic board and put in either phones, Itunes wont restore it. I get error 4013 with redscreen.
I tried DFU mode
I tried even having no screen on, ( all cables removed)
tried having face camera cable off only
tried having proximity and flex cable off only
What to do?
