Zip file firmware 17.xx or 18.xx

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

    I will need more time to see if this was indeed the stable version.

    However, over the past 12-14 month on my activities that I looked through, seems to be the latest okay FW.

    I can make a few observations already:

    - my RHR went back to my 'normal' state of 48-49 beats, instead of 51-52. However, maybe I just slept well (finally?).

    - some periods changed their status from 'maintaining' to 'unproductive' for some reason in Connect app.

    - overall - be ready for a few glitches when downgrading, make full reset and hard reset once it is done. Watch will have surprising behavior, I guess due to change from the new 'ways' to the old onces.

    - I could not install my favorite watchface, I mean it did install but for some reason if I reboot the watch it would disappear. Another thing - many of the apps now are too new to install, 16.17 is outdated, it seems.

    Overall I will have to test it extrnsively. I will have at least 1 indoor track, 1 outside long run and 1 treadmill test this week if things will go as planned. After this, I will update this thread and report back to the community.

    For those who have downgraded, it would be very interesting to know which versions of WHR, BMX and Sensor Hub Controller belong to them.
    These are the 3 components that are responsible for most of the unreliable, incorrect and missing health data?!

    Thank you very much. Is it possible that the sensors are up to date?

    Are you not afraid of installing software from unreliable sources?

  • 0 13 days ago in reply to 1860424

    But then these sub components does not downgrade with a software downgrade? For example sensor hub 32.24 was introduced in software 21.16...

    I really estimate the chance of someone modifying a proprietary software to steal/corrupt my runs as quite small. I don't use my credit card for payment in any case. ))
