Fenix 3HR reboot loop when loosing connection

Sorry to post in the Fenix 5 forum but I can’t find one specific for the 3.

As the topic header says, I’m having problems with a consistent reboot loop. Each time I go out of range of my phone I get the usual disconnect alert and then the Fenix reboots. Upon restarting it shows connected and then instantly reboots. This will carry on indefinitely.

The only workaround I have found is to frantically press the up or down button. This sometimes works in stopping the reboot but gets frustrating especially if I’m unable to do it at the time.

Does anyone know of a solution or can help me?

firmware version 5.60

Cheers
