After fixing all the screen, for some reason the LCD was turning on but it showed black and i dont know if is because im missing a screw or because the LCD doesnt work?
lol this is likely because you ruined the lcd. this tutorial forgot to mention that it is essential to apply heat, as the midframe is adhered on to the inner component.
Just need to get a idea on this phone, the silver backing thats usually stuck to the mid frame, when pulling out the old lcd this also came with it.
My question is whether or not that needs to replaced?
Also it changes screens all on its on.
