I was wondering if the board from the iPhone 4S would be compatible with my iPhone 4. I’m not completely sure, so I’m coming to the amazing community for help!
No , every Smartphone has its own BIOS system , its own connectors and its own architecture. To answer your question it’s No , and if you do it , your phone won’t boot as it won’t recognize the boot sequence of the new logic board.
No it will not work, won’t fit at all.
I’m not sure but the screws wont match up.
