Probleme mit Lasermodul Snapmaker 350

Yes 3D works CNC i never used.
I received a message on the display right from the start (even though the firmware was up to date) that the housing and the laser module needed an update. I wrote to Snapmaker and they gave me a file to update both units, after which the laser module no longer worked.

Snapmaker: " Please follow the steps below to update the firmware via USB.
To update the firmware:
Here is the download link to the latest firmware:
