Fenix 5 plus problem after V19.10

Fenix 5 plus. got it updated to v19.10. After this, i can't pair watch with the phone, and seems to not be able to get gps signal.

Additionally it works extremely slow, watch doesn't hold time, and freeze. When connected to Express it shows version 19.10, and no updates.

I have tried soft and hard reset. Online i was able to find v17.71 and tried to manually downgrade software, and it worked, watch shows v17.71, but it has same problem. Express still shows v19.10.

I removed all maps manually, and it works just a little bit faster, but nowhere near usable.

Is there someplace to download even older versions, to try that?

Is there newer version?

Is some software from other 5's compatible with 5plus to test out?

Any other suggestions?

It is useless to change firmware (even not recommended) 19.10 introduced the CiQ 5 system and works much better than before.
The problem you encountered is probably due to the battery that has reached the end of its cycle (low voltage)

I don't see how battery has anything to do with it? Li-Ion battery changes voltage all the time, depending on the state of charge. It has diminished capacity, but at full charge, normal functions should work. I was planing to replace battery, before all of this

I think I am also facing this issue. Did you get any proper solution?

I ended up contacting support, and sent it to service. I had no warranty so i paid for the service. They didn't fix the problem so i got new watch with new warranty.
