Now we need to remove the touch module on the original screen and solder it onto the new replacement screen.
Remove the earpiece speaker and sensor flex cable on the original screen. Then put a piece of paper under the touch flex cable. Heat with Hot Air Gun and pry up the touch module on the original screen.
Then apply low-temp solder paste to the touch module. Heat with Soldering Iron at 365℃ to clean residual solder paste and black adhesive. Clean thoroughly with Solder Wick afterwards. Then clean with PCB Cleaner.
Continue to get the touch module reballed.
