Hi Richard, it's been a while since I did this guide. From what I can tell in the pictures you will still need to use heat to remove the old screen.
Hello. To the best of my knowledge, modern touch screens do not require calibration due to the way a digitizer is designed to work. It sounds like your replacement is faulty or perhaps a cable is not completely secured. Check your ribbon cables and if those are good contact the vendor you got the screen from.
Did you hold volume down and power button at the same time to reset?
