Read these instructions, work methodically and make sure you carefully watch where you put your screws (I Blu-Tacked them to my bench) and you will succeed in this repair. The only tense moment for me was removing the home button. I highly recommend heat from a hair drier to soften the adhesive. Also, getting the button back in the new print panel assembly correctly without creasing any of the membrane is difficult - if you grip th button with your thumb and forefinger through the home button opening it can help. But yeah - all functionality including Touch ID has been preserved for me.
