Hello,
Since last night, my Fenix 8 has been rebooting continuously, and none of the procedures i found mentioned in the forum worked for me.
I finally managed to resolve the problem using the Unprompted Reset procedure, with a little twist that I'm sharing.
Here's the procedure I followed; it may be useful to others:
1) I turned off the watch completely by pressing and holding the Light button.
I checked that the watch didn't reboot automatically by waiting 30 seconds.
If the watch reboots automatically a few seconds after turning it off, you need to press and hold the Light button again until it turns off completely.
2) Once the watch was off, I held down the START/STOP and BACK/LAP buttons simultaneously and briefly pressed the LIGHT button to start the watch and initiate the reset procedure.
I waited about ten seconds, and as nothing happened (no sound, no vibration), I released both buttons and pressed them again.
Once again, nothing happened, so I released them again and pressed them again.
I felt a first vibration and released the START/STOP button, then a few seconds later, a second vibration and I released the BACK/LAP button.
The watch then displayed a cogwheel and a progress indicator and finally restarted by resetting itself.
Hope it will help !
Regards
Stéphane
