FW downgrade

You need the old fw file, than drag and drop it in suuntolink … BUT …
Downgrading can be problematic as maybe some changes couldn’t be reverted.

@sartoric Isn’t downgrading the watch a supported action?

@surfboomerang
I’m not that sure, maybe yes.
I would reflash the new one instead of downgrading.
No one ever experienced unsolvable pair issues afair

I have downgraded quite sometimes my SSU, and it seems to flash deeper the watch than just updating or resetting. After downgrade, the watch is in the exact state of new watch (welcome screens, etc…).

Ok, so I want to try to reflash with SUUNTOLINK, but it gives me that the watch is up to date, how to force it to update and how I can get the old FW file to try to downgrade ?

@mff73 How you got the old FW binaries ? I can’t find them on the website, I want to try to downgrade to see if it would help or not
