Garmin Fenix 6 Firmware 20.50 – Updated 14.02.22

Garmin released a new firmware release version 20.60 in April 2022. This software update follows up on the firmware version 20.50 You can read more about the firmware version 20.60 on this page. If you wish to continue with firmware 20.50, please read the instructions below.

Garmin released a new public release version of the firmware for Fenix devices. The latest public release version is 20.50. This firmware update should be considered as the main firmware or stable release after the Fenix firmware 20.30. Firmware 20.30 was released for the first time on 13th January.

Garmin Fenix firmware 20.50 started getting rolled out on 14th February 2022. It is being rolled out to the eligible devices in a phased manner, and you could wait for the firmware update to hit your device in normal chronological order or sequence. However, if you so desire, you can push the firmware update to your Garmin Fenix manually. The process of manually updating the firmware on the Garmin Fenix devices remains unchanged across multiple firmware version updates. We list the details of the firmware update process for 20.50 below.

Do bear in mind, the firmware update 20.50 for Garmin Fenix devices should not be manually downloaded or applied on the devices that are registered in the APAC region. APAC based users of the Fenix devices should wait for the update to be made available through update notifications on the Garmin Express or Garmin Connect.

We look at the process of manual updates of the firmware on Fenix 6 devices. But, before doing so, we look at the things that have changed between firmware 20.30 to 20.50 on the Garmin Fenix 6 devices.

Update – 21st March 2022:

Stalled Fenix 6 watch after firmware update to 20.50

Some early adopters of Garmin Fenix 6 firmware version 20.50 seem to be experiencing issues with the watch post update. The watch behaves strangely. In some cases, it may print random numbers on the watch screen. For others, it may print battery backup days in all the fields on the screen. Upon restarting the watch, it comes back with the same screen. You lose the watch screen and it appears that the Fenix 6 device seems to be unable to boot up completely.

Some users believe that this is on account of memory corruption on the Fenix 6 after the firmware update to version 20.50. It is early days though. Garmin support is looking into the issue. At this point, we are aware of at least 3 users who have shared their experiences of a stalled Fenix 6 watch after an update to version 20.50. Unfortunately, some users are out of warranty on the Fenix 6 devices.

Hopefully, Garmin should be able to address the issue and send in replacements to the users who have been affected by a (likely) firmware-related issue. We will post an update once Garmin shares feedback on these incidents.


What has changed between firmware 20.30 and 20.50 on Garmin Fenix 6 devices?

Garmin has listed incremental improvements of firmware 20.50 over the January month’s 20.30 firmware update. Some of these changes are bug fixes from the firmware 20.30, and others are feature updates on the Fenix 6 devices.

The following bugs have been resolved in the firmware 20.50 for Garmin Fenix 6 devices:

  • Fixed an issue on non-music devices that could cause a disruption of various metrics after being plugged into a computer.
  • Fixed an intermittent issue where the device would freeze when starting a round of golf.
  • Fixed issue that could cause altitude graph to flatline.
  • Fixed issue that would cause device shutdown when editing HIIT data fields.
  • Fixed issue where the device would create empty golf scorecards.
  • Fixed issue where the activity timer could be enabled on the Map-App.

The following improvements have been made to Fenix 6 devices:

  • The update process of the firmware on Fenix 6 devices has changed. The user can defer the installation of Fenix 6 firmware update, rather than being forced an automatic firmware update upon download of the firmware files..
  • Altitude calibration on the Fenix 6 devices has been having a fair share of problems since the last few firmware updates. The nightly altitude calibration on the Fenix 6 devices has been improved. It may premature to call it a permanent fix. It would be preferable to wait for the feedback about altitude calibration from the Fenix 6 device owners.

What are the essential characteristics of the Garmin Fenix 6 firmware 20.50?

Upon firmware update on Garmin Fenix 6 to version 20.50, your Fenix 6 device should run:

  • GPS: 5.30
  • Sensor Hub: 11.01
  • ANT/BLE/BT (Pro models): 6.11
  • ANT/BLE (non-Pro models): 3.00
  • Wi-Fi (Pro models only): 2.60

There has been some confusion around the ANT version 6.11 and version 6.15 on Fenix 6 Pro model smartwatches. ANT was updated to version 6.15 in the beta firmware 20.42. However, the public release firmware update 20.50, keeps the ANT/BLE/BT version at 6.11. If you had already updated the firmware to 20.42, you can choose to keep the ANT at 6.15. If you are updating directly from firmware 20.30 to 20.50, you will continue to remain at ANT/BLE/BT version 6.11.
