This will not work, as with all iPhones, each gen is different, in regards to all the plugs, clips and connectors. The housing and screen, all connect differently to the board, from gen to gen. Try it, you will learn from it, as long as it's not done without any fraudulent intent.
Hi Tharindu There are LEDs that backlight the screen. The one circuit of LEDs appear not to be illuminating. This could be due to a number of different reasons? Have you checked your screens connector cable on the board? It may not be in correctly and power is not getting to those LEDs? Have you tested the screen ? Sometimes the screens backlights are faulty? Check the integrity of the screen connector cable. There may be a tear in the cable thereby breaking the flow of current to the LEDs?
