Zip file firmware 17.xx or 18.xx

2267414 13 days ago

does anyone has older firmware for 955 Solar? i'm getting frustrated fixing this OHR and ABC Sensor on 20.32 and 21.19 firmware, still not getting fixed.

I was wondering if i could fix this by downgrading the firmware.

yes i've tried everything such as reset total from settings, the reinstall software by clicking light button 8 times, plugging my watch to garmin express and connect, nothing happened.

please if anyone has the 17.xx or 18.xx firmware, let me know

You can download past firmwares here, unzip to the Garmin folder on your watch. I'd recommend 15.19 for the best working OHR

15.19 - https://drive.google.com/file/d/18Je6tnk2rudV4cVtPwsTagPP-21iYg5R…

Just unzip into the Garmin folder on your watch. Then unplug the cable and install on the watch. Backdating software will revert your watch to default settings.

page 1 of this topic. Actually the first answer has the link to a lot of earlier firmwares.

I didn't pay attention, initially there were links to other firmware. As I understand it, it is necessary to downgrade the firmware using the new functionality for reinstalling the firmware? Is there a detailed instruction on downgrading the firmware?

The new reinstall feature will only reinstall the actual firmware version on your watch.

Here is a link to a topic on how to do it.

For downgrading, use the 2 files from the .zip you downloaded, connect your watch to your PC and copy them to your GARMIN folder on the watch.
Once you disconnect your watch from the PC, it will automatically ask you if you want to install the older version.
Watch will be reseted, so make a backup upfront.

Additionally here is a more detailed instruction. Its for the Fenix, but steps are the same as long as you have the firmeware for the forerunner.
