Be careful when re-installing screws on reassembly. I mistakenly put the longer screw from the battery connector in the outboard hole, and wound up twisting off the lug that is only lightly soldered to the metal below. Still have 2 screws and system seems to work fine.
Good guide, expensive replacement parts.
First time around, completed assembly only to notice that a small piece of blue film which had covered a bit of adhesive tape for the home button, had been left behind and was clinging to the inside of the glass near the bottom. Tried to quickly pry up the corner before adhesive had fully set, and wound up cracking the new screen. Went looking for a cheaper second replacement and found one for less than half the price (iFixit shipping was 12 bucks vs. 5 for the other guy).
Second screen got here through the polar vortex of late Jan 2019 with no delay. (Way to go USPS!) Second time around went much quicker, though I broke loose one of the 3 lugs for a screw holding down the LCD screen connector (step 36). All good and works perfectly. Thanks, iFixit!
