I have a logic board of iPhone 4s 16gb and I have an iPhone 4 8gb. So I want swap the logic board of iPhone 4 with logic board of iPhone 4s. So is it possible do it or thee will some problems..
No, not possible. The ribbon connectors connect differently.
No , every Smartphone has his own BIOS system , his own connectors and his own architecture. Well to answer your question it’s No , and if you do it , your phone won’t boot as he won’t recognize the boot sequence of the new logic board
If you put the iphone 4s battery with the iphone 4s motherboard will it work? theres juts the iphone 4 screen and charging port
