Unstable connection with HRM Run

I could install the 4.29 with your instructions, thanks heaps! Even though I switched the automatic update function off, the 245M managed to download the 4.40 data (probably through Garmin Express, Connect or Connect App) and installed it over night...

Will try to repeat the whole thing and do a test run to see if it works. However, we are still facing this problem. If result of the test run will be positive, I will follow up on this with the Garmin Support team. Hoping they will make their US colleagues fix the code with the next update.

Hi, 
Garmin pushes update as soon as you use Garmin Express or if you connect thru Wifi.

You can avoid update :

* Removing the GUPDATE.GCD file, in /GARMIN, as soon as the device asks for an update.

or

* You can patch the file GarminDevice.XML and change GUPDATE.GCD to something like GUPDATE.GCX
This would avoid the update request message (and action)

Warning: the xml file is very complex, so backup it before.

Oh, dear, mine was updated to 4.40 even though I’ve switched Auto Update off.

Such a bad UX on Garmin’s part. Will it really help if I won’t update via Garmin Express and remove any wifi connection on the watch? Cc Former Member

What about downgrade to stable 4.20? Personally I never faced the issue with that version (it started once I upgraded from 4.20 to 4.40).

See in the instructions above. Package with 4.29 contains stable 4.20 as well.

Can you confirm, that the watch shows v4.29?

Yes, it was 4.29. I downgraded to 4.20 now and will try that too. When I deleted the GUPDATE.GCD it poped up again after I started Garmin Express. Probably won't be able to use Garmin Express anymore. Will the 4.40 update not show up if you do that XML thing (even if you open Express later on)? Not being able to rename files in the Android File Transfer with a Mac also..

My fault guys.. didn't put the RemoteSW file into the folder on the watch. Installed the 4.20 -now- including the RemoteSW downgrade file. Hope this will make a change.
