@nicolati Hi,

I confirm the occurrence of the same error. I have three EAP653(EU) v1.0 units currently running on beta version 1.3.50 Build 20250819 Rel. 57463.

The attempt to update to official version 1.3.7 ends in failure. The controller throws an error and adds the devices to the "List of corrupted devices" (Lista uszkodzonych urządzeń) in the update menu.

What's strange is that the automatic update feature sees the new version, but when I manually check by clicking the "green arrow" (check for updates), it shows that the latest version is already installed. It looks like moving from this specific beta to the newer official software is blocked or contains a file verification error.

Has anyone managed to solve this problem, e.g., by uploading some intermediate version?

Best regards!
