Torx 2 also works :)

Tried pentalobe drivers but had to get a Torx 2 in the end, possibly some variation across regional models.

Really helpful guide. Only hiccup was that on my handset the screws holding the casing together (Step 2) were Torx 2 rather than pentalobe, possibly a regional variation. I opted not to remove the loudspeaker (Step 10) as the ribbon cable was firmly stuck down and I worried it would break. This meant I could only cleanly remove the adhesive pad in line with the charging port. I was able to prise out the battery using spudger and screwdriver to scrape the other pad from the phone body. All now reassembled and working properly!
