    • Remove the two 2.1 mm Phillips #00 Phillips screws securing the home button control board to the home button mounting bracket.

    I have just replaced the adhesive on an iPad 4 and did not need to remove and replace the home button. There seemed no reason to remove the button because the adhesive strips did not encroach on the button mount. Removing adhesive is aided by rubbing it with iso propyl alcohol (rubbing alcohol) after striping back the plastic film that covers it. It would be nice if the adhesive would come away with the plastic film but this does not happen even with gentle heat. If you use shart instruments to remove the adhesive its very easy to damage the underlying paint.

    • Use a pair of tweezers to peel the clear backing up off the adhesive strip directly underneath the home button ribbon cable.

    • Lay the home button ribbon cable down on the adhesive strip and smooth the cable down from the center out, taking care to not trap any air bubbles between the strip and the front panel.

    • Do not peel the clear backing off the strips just yet.

    • Use a dry microfiber cloth to clean the LCD and inside of the front panel glass. You may want to use canned air or an air compressor to blow away and dust.

    • Use a pair of tweezers to peel the clear backing up off each adhesive strip.

    • Close the front panel down onto the iPad, careful to place it within the plastic bezel, and careful not to get any dirt or fingerprints between the glass and LCD.

    • To ensure a good seal, place the iPad face down on a padded envelope or cloth and pile a couple of books above it to weigh the screen down. Leave it like this for a few hours before using.

    Just anted to remind everyone to connect all your cables BEFORE sticking the screen down!!

    …before attaching the LCD, in fact.

    To go a step further in caution, leave the backing on the adhesive strips, attach all the cables (and replace the tape over them if you like), making sure all of the motherboard screws are in place. Then lay the LCD on top (without screwing it down), lay the glass on top of that, and TEST. Make sure you have full LCD and digitizer function. If not, do a hard reset and test again. If still not, dismantle everything and re-check the cables—they should be fully inserted (usually the white line should not show at all), with their latches down and no sharp crimps. It’s surprising how small a change in digitizer insertion can make a black screen suddenly function just fine.
