Hello BenAir,
These firmware versions are not compatible.
If you attempt to upload the wrong firmware, you will receive the following error message:
“Wrong Lead-In”
Note: During the upload process, the camera automatically verifies whether the firmware matches the device model. If it does not, the upload will be rejected. After this message, the correct firmware can be uploaded without any issue.

MX-System Release 8.0.1.42-r6

We will clarify this detail at our Download Page!
Thanks for the question , Jörg
