Bootloop after update

1295754 over 3 years ago

Hi there!

My girlfriend loves her garmin vivoactive 3, she has it now for more that 3 years.

Warranty of course is over.

Last week she was complaining the watch doesn´t work anymore after software update: bootlop.

It will restart and restart again vibrating.

Garmin Express Software says everything is fine, connecting.

Windows does connect, mass storage available, diagnostic screen on the watch is available

but I can not convince the watch start working.

What can I do?

Diagnostic Screen says: SW 7.80

alsomore stuff but no error

The error will come after restart.

Regards

Ralf

You can try to hard or factory reset it, or perhaps flash a beta image to the watch to see if it reboots and then updates itself. It could be a bad flash or corrupted files. Perhaps better to ask Garmin support for suggestions.

1) hard factory reset: how? On/off 20s did not work

2) where to download an image for this watch? I´m able to do this but missing file and instruction

Thanks in advance

Ralf

https://forums.garmin.com/sports-fitness/healthandwellness/f/vivoactive-3-3-music/263519/vivoactive-3-software-version-7-72-beta The download link is still active. You can flash 7.70 or 7.72, instructions in the zip file:

If you need to backdate software to 7.70, rename GUPDATE_770.GCD to GUPDATE.GCD and place the file in the GARMIN directory.

So, unzip the file and extract GUPDATE.GCD and use the PC to store it in the \Garmin directory. Restart the device and it should start flashing. First have a look at my last post though, perhaps the 'Master Reset' works for you.

Look at this post :

Had the same situation after trying to install a watch face, took it to the Garmin service centre in Hong Kong, I was prepared that they would just give me a new one, yet immediately they told me that there is a "master reset"! And it worked! The guy was even kind enough to print me th reset instruction, so here it is guys and girls, give it a go.

Press to turn on with Logo -> Release then press and hold (quickly!)
Release when it vibrates 2 times, wait for 3rd vibration then press and hold until the 4th vibration

-----

EDIT:: THE button trick worked. But to add to it, after the 4th vibration, you need to release. Then there will be a 5th vibration and the unit rebooted fine. I did the updates again and everything is working fine now.
