Help! My 520 keeps rebooting every 3 secs

Former Member over 7 years ago

Help! My 520 since yesterday went into a reboot loop. It shows the Garmin logo at the start and then it reboots again and again and again. Anyone encountered same issue? How do i hard reset this bugger?

Try

Prompted non-vol clear –

Turn device off
Hold the Down key while powering on the device
Continue holding the down key until the “Factory Reset” prompt appears
Select OK to clear

Non-prompted Non-Vol Clear - Clears NV and deletes all FIT files including Activities, Courses, Workouts.

Turn device off
Hold Lap/Reset and Start/Stop
Press and release the power button
Continue to hold only Lap/Reset and Start/Stop
Release Lap/Reset and Start/Stop when the Garmin Logo is cleared
The unit will restart and clear non-vol

Problem here is i cant turn off the device. It just goes into a reboot loop until the battery has died and it switches off. Once i plug in the power, it goes into the reboot loop again.

Try holding the power button down for 10 seconds.

You may also be able to intercept one of the start-ups if you time it correctly and hold the buttons as it restarts.
