How do I glue the phone back together when I am done? Do I need to add more glue? Do I just heat it with the heat gun again and squeeze it together?

I agree, this is unclear.

The "Parts" section at the top includes "Precut adhesive card", but when you click on that item, it gives a whole bunch of different size options for rolls of tape (8mm, 5mm, 1mm, etc.) and it's unclear which size to get. Does anyone have details of this?

Battery good so far, instructions clear enough! I turned the phone on immediately after replacing the battery to make sure everything worked. This was to avoid putting the phone back together only to find it wouldn't turn on, and then having to dismantle it again.

One thing you may want to pay attention to is not to separate the screen (front) layer from the phone, rather than the back side, which is what I did on my first try.

I opted not to get adhesive strips and I simply applied thinly cut electrical tape around the phone's edges, on the outside, to keep it together after fixing. Not terribly aesthetic but does the job well enough, especially if you use a book-style phone case like me.

Pretty doable fix for a first-timer, especially when using the fixit tools (picks, spudgers etc). Happy with the results. Thank you for the guide!

Additional tips (1/2):

1. When buying tools, consider buying a suction handle. This was useful to use on the heated back cover to open up a gap to insert the opening picks into.

2. Consider removing the SIM tray before heating the back cover.

3. When heating the glass back cover, consider wearing some resistant gloves when heating the glass back cover. The glass can get a little got and I was only using a hair dryer on the highest setting, rather than a heat gun.

4. When you have managed to wedge your first opening pick underneath the back cover, take another pick and drag it along the nearest part of the gap to open up the gap further before setting that pick into position. Repeat as you go around the entire edge of the phone. However, BE CAREFUL to not push the opening pick too deep, especially around where the volume buttons are, as the fingerprint sensor cable is located close the edge of the phone.
