How can I downgrade to a firmware I have stored as sof-file on my smartphone? Suunto app doesn’t open it because of the message that it is damaged or an unknown file type.
I want to downgrade two versions before the actual firmware, the pkg is not stored in the service menu of the Vertical.
Look at your sof file name and create an hyperlink formatted like in this thread

Send it to yourself and open it with SA, it should download and install if no error in the name.Suunto Spartan Ultra (since 2016) FW: 2.8.24 (retired)
Suunto Vertical all black
Wife : S9PP
SA: Always the latest beta :)

https://firmware.geo.movescount.com/production/Rostock-fw_2.39.20.20609-O-26950e90.sof
but I don’t know how to create a hyperlink of this URL and how to open it with Suunto app.
If you have a more detailled description I would be very happy and thankful …
Edit: Solved with the gentle help of @sebchastang

The update lost my Stryd and HRM Bluetoothed paired connections, requiring me to set them back up. However, I’m now only sporadically getting my Polar H10 connected when I start a run. When I go into Settings -> Connectivity -> Paired Devices, I see a lot of “- -” entries that cannot be removed. See this video.
On top of that, the watch seems to lose connectivity with the Stryd pod dropping power like the old Abit3 days. Here is a screenshot of my run this morning. Note the power drops to zero.

@atoponce I had the same issue. – sensors are then impossible to remove
-
@atoponce I had the same problem (https://forum.suunto.com/post/175724).
To remove them, I try to reboot the watch (12 second on upper button), then downgrade to previous firmware but it doesn’t work. The “–” are still here. The only solution was a hard reset… Great… I’m really happy to set again profiles !! -
@fondueaufromage thats the biggest bad thing that suunto isnt working at that! Its so hard that we could safe all things in the App? Custom sport modes e. G. I didnt understand this
-
@brechtvb So I just tried it. When no sensor is paired, searching for new sensors finds both. But once I pair one of them, the other no longer shows up in the search at all. On both sensors, after pairing, speed/cadence lights up, which makes no sense, and on both you can set the wheel circumference
. And no option for auto calculating the value…
It’s sad that such basic things don’t work with Suunto. It makes me think about going back to Garmin despite their other flaws… -
Anyone else still having issues with the “off route” alert not working when going off course? Hoping this can be solved quickly as it’s pretty critical when trail running/hiking! Thanks!

@Krista.B Today I was running in the forest. I had navigation on my watch. I unexpectedly got off the route and the watch didn’t warn me.

Hi everyone!
My Suunto Race has stopped syncing with the app since the latest update. It shows “Syncing activity” and then flashes “Watch update needed” for about half a second, followed by “Not connected” for about a second — and then it just repeats this cycle over and over.
Has anyone experienced something like this? What should I do?
-
@Eliseev-PA I’m experiencing same behavior with latest App release on iPhone 17 Pro Max. Before switching phones everything was working perfectly fine on iPhone 14 Pro.
What phone are you using?
-
@Danny-poleg My Vertical still apparently keeps a constant connection (and constantly disconnects/connects when I walk from room to room) to paired bluetooth devices (HRM, Stryd) all the time, even when activity is not running.
So no, this helps nothing.
-
Today during a hiking activity after 6.5 km the SV1 stopped displaying the HR from my H10 and hence ZoneSense stopped working. No oHR readings either. The H10 strap is nearly new and the battery of the sensor is at 90%. This thing never ever happened before. Meanwhile the H10 was connected to my other watch and as expected, no issues at all.
Was that just a glitch or a bug that I got after installing the latest hot fix? -
@Highlands I had this happen with a Suunto Smart Sensor last week, so prior to this hotfix. Same thing, though - lost connection midway though activity and never re-connected eventhough there was plenty of battery life. I was able to reconnect the sensor after completing the activity and to other devices, so I don’t think it was an issue with the external HR.
Like others, I was also experiencing random vibrations on the watch (both during and outside of recording an activity) which I think had to do with the external HR dropping and reconnecting bluetooth. I haven’t had the issue in a few days after performing a soft reset. Not sure if it’s all connected, but it seems like there are still a few issues with the new bluetooth setup.
Edit: Another issue this presents is that once you lose the connection with an external HR (whether due to a bug or a dead battery, etc.), you no longer have any HR reading. I think the expected behavior would be to have it fall back to the watch’s optical HR so you at least have something. I believe this is how it works with most other companies.

I did a walking activity today that is not uploading even though the watch seems to be syncing fine. It’s saved on the watch logbook. Never happened before this update. A running activity from yesterday (after new firmware as well) synced fine.
-
My Race S updated tonight. I woke up as it was updating and got a really bright screen. Okay, just let the watch do its thing. It rebooted and presented me a “Your watch has been updated” screen, waiting for my “OK” press. After this it has gone back to DND mode and I continued sleeping.
As expected sleep tracking for the night is just trash. Even more: heart rate tracking stopped with the update and started again 07:10 in the morning. Way after I pressed “OK”.Could we have the Garmin way of doing updates? Watch is telling there is an update waiting and wether it should be done now. Even with an estimated update time. So you can do the update whenever it fits in your life.

@duffman19 Thank you very much for taking the time to answer. I’ve been experiencing everything you described.
Of course, I’d love to test for Suunto but I’d rather they sent me a test device for that purpose. My SV1 is my daily driver and I strongly prefer it to run a stable software.
Couldn’t agree more with you that when the external HR disappears the watch should default back to oHR.
Edit: As always, after installing the latest software update, I rebooted my Suunto watches twice by holding the upper button for 12 seconds or so. -

Is there any practical difference between rebooting the watch 3 times, versus just once?
-
@Squirrel Thanks for making me think about this.
Here’s what I found:Rebooting (often referred to as a “soft reset”) is typically recommended as a single action to resolve minor glitches, such as temporary unresponsiveness or software hangs, by pressing and holding the upper right button for about 12 seconds until the watch vibrates and restarts. This clears temporary memory issues without erasing data.
Official Suunto advice emphasizes that repeated resets should be avoided unless directed by support, as they indicate deeper problems like hardware faults, and may require warranty service instead. If your watch is experiencing issues, sync data first, then try a single reboot; if it persists, contact Suunto support for model-specific guidance.
