+1/+1PM upgrades seems to finish, but didnt upgrade

[Littlericket]

Hi all,

i have 2 out of 10 shelly 1 plus at my home which are not correctly upgrading. I dont know if they both were in the same double-package and have some common differences with the other ones in this home.

When applying the upgrade, the process runs successfully, but after rebooting the shelly is still running the previous version, even if the logs tell me that everything went fine.

Tried downgrading, upgrading (from 2.11.2 to 2.12.1) , reverting to stock. The shelly always comes back with the previous version 2.11.2.

Below the log entries when starting the upgrade.
