if I have a 5S but I have a screen for a 5c can I swap the flex cables to make them work with that 5S mother board and be able to put fit it back on the 5s with the 5c screen but the 5S cables?
No, the LCD on the 5C and the 5S are not compatable. The flex cable is different.
No not only is the flex different and u cant really change it without very expensive equipment but also the screen frames are different to fit their respective phones.
