This was my first phone repair and it was successful! I do have a lot of experience working on laptops, and this is much more fiddley, if otherwise familiar. I definitely recommend reading through all of the comments first before starting. Took me closer to 4 hours, but I was carefully re-reading and double checking each step, since phone repair is new territory for me.

The advice for re-attaching press connectors for re-assembly given in step 15 should be repeated here, since the reader will be moving from the bottom when re-assembling.

It wasn't clear to me from the picture, but don't try to pry the midframe piece up from the back cover. Pry the vertical edge of the back cover just a little out from the edge of the midframe. This releases the clip rather than fighting the clip, and the midframe will pop up from the back cover.
