How to downgrade version 21 on Fenix 6 Pro Solar

Firmware Version 21.0 BREAKS the STRENGTH TRAINING functionality and usability. For reference, check here https://forums.garmin.com/outdoor-recreation/outdoor-recreation/f/fenix-6-series/294427/software-version-21-0-and-strength-functionality or here https://forums.garmin.com/outdoor-recreation/outdoor-recreation/f/epix-2/294098/strength-workout-bug-with-8-18. 

SO...how do we downgrade to the prior firmware version?

Hi,

It's fixed in the latest Alpha 21.71, you can upgrade, validated the fix and give your feedback

Question was how to downgrade - not upgrade to be involved in testing program. Not everyone want's to be part of buggy not ready releases

Another bike ride and this time without navigation

Todays's ride  without navigation drained 10%

Moving time : 17:23:00
Total Time: 1:51:30 (Coffee Stop)
By the mistake i did not return to bike mode and continued my journey - silly me.
Battery Consumption 100% down to 90% - this is crap.

Conclusion with Speed / Cadence sensor. In previous 2 rides Cadence sensor was connected but Bike Activity did not use it. I tried in multiple ocasion to connect to it - re-synch bike sensor - and when not in bike mode - Cadence sensor was connected. In Bike mode bike sensor was connected - but no data showed. This bug is since version 21.


BUG in version 21. Cadence & Speed sensor in Bike activity not recording data - but it is connected.
I also replaced battery to new one - and same story, Connected but not collecting data.

Based on my observation seems like watch on version 21 has problems with BT connection for multiple devices.

I don't have problem when i use BT heart rate and Cadence/Speed Sensor on ANT+
but when using both in BT - only 1 is working - and Cadence & Speed is down then.

I have Bluetooth issues too but it shows mainly due to the fact I can't connect to my airpods without restarting the phone first. This might be related to the HRM pro strap as connecting without wearing the strap works fine

I got another ride.

List in total :

Bike Ride 1
Moving Time : 5:39:56,
Total Time :  7:36:05,
Battery Consumption 100% to 4%
Navigation On
(Cadence & Speed sensor not connecting properly - issue with BT connection caused by Version 21) <- but on Garmin Connect Web - i can see some data for that Crappy but still - on watch i had no Cadence visible.

Bike Ride 2
Moving Time : 1:48:33,
Total Time :  5:04:05 (Coffee stop - so clicked Pause > Restore later)
Navigation On
Battery Consumption 50% to 3%
(Cadence & Speed sensor not connecting properly - issue with BT connection caused by Version 21)

Bike Ride 3
Moving time : 17:23:00
Total Time: 1:51:30 (Coffee Stop - i paused activity > Restore Later. )
Navigation Off
By the mistake i did not return to bike mode and continued my journey - silly me.
Battery Consumption 100% down to 90% - this is crap.


Bike Ride 4
Moving Time : 21:19
Total Time : 52:51
Navigation Off
Removed BT Speed & Cadence Sensor from Sensors & Connected to Same Speed & Cadence Sensor but over ANT+ and it worked.
Battery Consumption 100% down to 91% - this is crap.

Is there any particular version you want to downgrade to?

I have backdate files for almost all versions.

BTW you can't downgrade subsystem software such as GPS or Sensor hub. Just main firmware. (it might still be possible to downgrade to ANT/BT/BLE 5.xx)

You can downgrade to 20.50 by using the backdate file from the 20.8x Beta. You can find the beta and instructions to downgrade here:
