Hi everyone. I am really desperate. I have two iphone 5, the first one is broken of screen, camera and power button. Second one is useless because logic board is damaged. I decided merge the functional parts (hardware) of each one and to make an iphone completely functional. I use the logic board of first one into aluminum case of second one, this is because the second one has a quasi-new case. I put very carefully the parts, i did a good job!! Iphone started, i could access photo albums, camera was functional, power button ok, i felt completely happy. But iphone doesnt activate. So... I tried it by restoring iphone. After restoring nothing changed. I have an iphone turned on, but with problems to activating. After this i tried restoring by using itunes. Itunes downloaded file, etc... But at the end itunes shown an error: unkown error restoring iphone (1) ¡ I tried to restore again but always is the same error, itunes is not showing to me the serial number of iphone, instead there is: n/a I think that because itunes cannot detect the serial of iphone this couldnt be restored. I tried too by using a mac directly and result is the same. Is there any with the same problem? Any suggestion? Thanks a lot.
