It's better to use bluetooth fake location app to unlock ALL functions.
For the details, see the comments below, like https://gist.github.com/imReker/fba069c6cae7407509863b0ed78da2a7?permalink_comment_id=5889305#gistcomment-5889305
After a lot of testing by the people in the comments, it looks like only ECG will work.
So just replace the first three files:
com.apple.HeartRate.notifications.plist
com.apple.HeartRate.plist
com.apple.private.health.feature-availability.plist
@imReker working on iOS 18.6.2 and watchOS 10.6.1, following the @lucidyan steps (replace parameters instead of entire files).
ECG has the "no available on your watch" message but it is working OK on the watch.
Irregular, Cardio Fitness and High & Low HR seems to be OK.
Apnea and Oxygen has the "no available on your watch" message, but I'm receiving an S9 soon to verify if it's due to the lack of sensors in S5.
AFib History "no available in your region".
Anyone with the .plist files for trying to enable AFib history?
