Rather than remove the midframe, I just propped it up a bit more than 90 degrees from the phone onto a box, just so there’d be one less of these fumbly connectors to redo during reassembly.

I used a heat gun instead of the headed bag thing. Took my time and slowly got the adhesive soft enough to get a suction cup to start raising the screen off. I went very, very slowly about all of this and was lucky enough to keep the screen fully intact and functional. There’s an awful lot of adhesive, and I’ll repeat others in saying not to let the screen fool you. The actual piece of screen extends lower than the visible area, which could get you in trouble.
