Looking for previous 26.xx firmware for my Fenix 6 due to altimeter issue with FW27.00

Hi all.

Is there anyone who got a copy of the firmware 26.xx for Fenix 6 ?

Is there anyone tested a firmware regression ?

Got FW27.00 and lost elevation value (altimeter is now displaying wrong value and Garmin told me to it need service for 200 $).
It was working on 26.xx version, so I would like to revert back to FW26.xx.

Any help, idea would be appreciated.


Regards,
