Force firmware downgrade on an Ambit3
-
Hello
I just purchased a used Ambit3 to use while kitesurfing after my Amazfit died after many sessions in the water
While it’s not completely necessary, I am looking for a way to downgrade or hack the software since I’ve learned that איק Ambit lost the ability to display RTL languages in notifications in one of the firmware updates along the way (if true, go figure).
Do you think it’s doable?
Thanks

Any idea anyone?

Thank you. Any info on what was the latest version to support RTL languages?

No idea.
I have not Ambit since looooong time.
You can first find all FW files you can, and downgrade gradually and see.
Most difficult is to find FWs.
We have seen here links for Spartans or S series, but for Ambit, no memories in my mind. -
@Tom-Z , are you sure it happened after watch firmware update and it’s not related to MC app version or moving to Suunto App?
Latest FW is 2.4.17, released on 2017-06-26, one before was 2.4.1, released on 2016-12-01 . I wouldn’t be so sure if anything older than those two would even work with latest MC app or current SA, even stepping down to 2.4.1 might introduce some issues with mobile apps (though it does work with Suuntolink, tested). And downgrading to anything older would also mean loosing of quite a few features - https://moveslink.static.movescount.com/release_notes/SuuntoAmbit3_ReleaseNotes.html
But technically there’s no problem forcing a FW downgrade itself. Just be ready for update notifications in Suuntolink & Moveslink2 and possibly in mobile apps as well.
Here’s a generic URL for A3P FW files:
https://uiservices.movescount.com/devices/Emu/69.4.17414/<rev>/binary?appkey=<appkey>Replace <rev> with one from release notes (“2.4.17”,“2.4.1”, “2.2.16”, …) , you also need to provide required <appkey> yourself. If you are using Suuntolink on Windows, you’ll find it in %appdata%\Suuntolink\suuntoapp.log . Or look for production.json at Suuntolink installation folder.
Suuntolink uses a certain naming convention for FW files when it downloads those (e.g. uiservices.movescount.com-Emu-69.4.17414-2.4.17.sfi ), but it doesn’t seem to really matter. Once you have the file you just drag-n-drop it onto drop area somewhere in lower portion of Suuntolink window, you’ll notice when you’ve found it. And as always, use it at your own risk, yada yada yada …
