After a failed GPS update two weeks ago, my Garmin is stuck in a sort of boot loop. When I power it on or connect it to a charger, the "GARMIN" logo appears, it beeps, shuts off, and repeats this cycle indefinitely. I found some old forum threads discussing this issue, but they are closed now and none of their solutions work for me.
I've tried resetting the device by pressing the lap and resume buttons while powering on, as well as pressing the lap button while powering on to enter mass storage mode, but neither method works.
Does anyone have any idea how to fix this?
The battery seems fine since it takes a long time for the device to stop booting on and off until the battery is dead (and the battery was "good enough" before this issue started).
I can turn it off using the reset trick (lap + resume), but when I power it on or connect it to a PC, it starts the same booting and resetting cycle again.
