Readme before task:

Before separating the glass… make note of exactly how the front aligns(overhangs) the frame, there's nothing to guide it back except your own steady hand.

Also: when prying the front glass, it will shatter and pelt you with shards and dust. Put tape over it before starting.

It's not clear in the article… the LCD sits in the frame and isn't attached to the digitizer/front glass. This means to replace glass, no need to buy LCD, or remove motherboard or battery.

I reassembled the outer case without using tape, it seems pretty secure and snapped into place satisfyingly.
