  • If the screen is cracked you might want to use some tape to protect your eyes from glass shreds and get a better grip to open the phone.

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!

Overall a very helpful guide . I also had torx screws in mine . The torx screws are tiny , so make sure you have the right screwdriver before starting . We didn’t bother removing the loudspeader assembly either (Step 10) . You can just prise up the ribbon cable (carefully) . Add heat if necessary . Now to the biggest problem . Removing the old battery from the phone . What a nightmare ! It’s really stuck down .We took our time using a hairdryer (no heat gun) , and a flat head screwdriver , and went from one end to the other prising it off gently . It still took about 20 minutes . Saying that . Don’t rush it , as it’s the final stage . Also . If you do use a flat head screwdriver then don’t twist it , as you might damage the casing . Just slide it underneath it applying heat . Total time to remove the old battery was 90 minutes , but about 50 of those were spent just getting the first 2 screws out . 20 minutes to put the new battery in and reassemble . Make sure all flex connectors are properly reseated .
