On my phone, the white sticker was in the bottom right corner, rather than the middle right side. However, the screw types were all the same as listed in the step above, so proceeding to remove the sticker and screws worked fine.

Re-using the existing adhesive worked OK, but not perfect. There’s a little gap near the volume buttons where the back separates from the inner lining. I’m using a phone case, so I don’t mind - it’s good enough that the back won’t come off while the phone is in the case.
