Watch not updating gps and bluetooth

Hi all,

I have a Fenix 6s pro, when I did update to 16.70 using Garmin Express (from PC) the watch got stuck on update.

After a force restart it showed me GPS version: 0.00 and ANT/BLE/BT: 0.00. Gps and bluetooth are not working.

Every time I put a new file in RemoteSW, the watch gets stuck on update, no matter the file (006B310701.GCD or GUP3293.GCD) or the version (GPS_v450 or GPSUpdate_530 or ANT_BLE_BT_v360 or ANT_BLE_BT_v606 etc).

Garmin express update gives the same behavior.

What I've tried:

- hard reset - same problem

- update to 18.80 - it worked fine for main software but not for GPS & ANT/BLE/BT

- cleaned RemoteSW and restarted

- tried with one file only, with both files - same problem

- leave the watch in update for hours - battery drained to 0

I have full access to the watch and the files via PC.

Any suggestion is welcome.

Thanks,

Stefan
