Why iphone 5S display blue screen after reinstall motherboard?
Maybe the screws on motherboard were installed with longer one, so that broke the screw.
How to repair?
You will need microscope, Special enameled wires, heat gun, blade, thinner, tweezers, etc. Special enameled wires are taken from ear speaker or loud speakers.
Step 1: remove all broken lines remainder from the position, with microscope, blade.
Step 2: add enameled wires to the position where set screw, with microscope, heat gun, tweezers; the straight lines are “blew” one by one, even much smaller than hair, just can see clearly by microscope.
Step 3: clean. Done!
Kindly reminder: Do not exchange these screws, otherwise will cause troubles!
Thank you so much :)
