The tear down pictures are great, but in my Charge 3 I needed a T-1 and a T-2 driver

Julien Baldwin - crwdns2934203:0crwdne2934203:0

Same, my ifixit pro kit only had a driver for the external screws and did not come with a small enough driver to remove the screws inside the charge 3 unit. I'll need to get the smaller bit from a different kit.

Brian Hall -

Which step in the teardown guide needed the T1 driver?

ShellingRook27 -

Great job on this tear-down. Thank you, it really helped in my screen replacement.

AndyZ - crwdns2934203:0crwdne2934203:0

This tear down was very easy to follow. The heart rate monitor was also sealed in with some adhesive for me too but a little heat gun took it right off. I had suspected water leaked in and that in fact was the culprit after inspecting the connection. corrosion all around the HR monitor.
