How to update the Garmin watch manually (Alpha 22.73). Step by step.

Hello, today I will tell you how to update Garmin watch to new alpha software (22.73 version). This article won’t be long, but since I’ve noticed people asking how to do this, I’ll try to keep it as short as possible.

You need to download the appropriate files for your watch from the Garmin forum and upload them to the watch. Alpha Version 22.76 update is in the Alpha stage, so you will need to do it manually to upload this update to watch via USB cable.

To do this, you need to download the necessary file, connect the watch to the computer and upload the downloaded file. I will show you how to do it below. And I will add a video of how I did it.


Remember, this is not an official update so it may contain some bugs. I haven’t noticed them yet, but versions like this usually have them. Therefore, I would not hesitate to update the watch if serious competition is expected soon. I am also not responsible for a failed update; everything is your responsibility.

Step 1. Download right files

  • I have Garmin Fenix 6x PRO, so I downloaded update files from the Garmin forum for Fenix 6X. If you have a different watch, choose files suitable for your watch.

Step 2. Unzip

  • Once you have downloaded the file, unzip the file, which is in the SystemUpdate_2273 folder. You need to unzip a file named GUPDATE.GCD on the screen or somewhere else (there is only one file in the folder)

Step 3. Connect your watch to your PC

  • Open your watch folder. It should be like My computer->fenix 6X Pro-> Primary->Garmin. And you need to transfer the GUPDATE.GCD file to the Garmin folder.

Step 4. Update your Garmin Watch

  • Disconnect the watch from the computer and a message about a possible watch update should appear automatically.

When updating your watch, don’t panic if it takes more than 2 minutes to update. It took me about 5, and the loading bar looked frozen at some point.

You don’t need to do anything else, everything should update automatically, and the previous information will remain on your watch.

What’s new with Alpha Version 22.76 update?

  • Fixed a potential shutdown on the sensors about page.
  • Fixed a potential issue where the Daily Floors Climbed Goal alert would not alert.
  • Fixed a potential issue where Battery Saver mode would randomly turn on after an activity or accessing a menu.
