I am trying to roll my firmware back from 1.57 to 1.52 using Z-Wave JS. I went and downloaded the firmware from https://files.inovelli.com/firmware/LZW31/Beta/1.52/
I also tried downloading the firmware from github https://github.com/InovelliUSA/Firmware/tree/main/Black-Series/Z-Wave/LZW31-Dimmer-Switch/Production/1.52 by downloading the whole repo as a zip, unblocking the zip, then extracting.
I end up with a 276 KB otz file.
When I attempt to update the firmware using Z-Wave JS with the otz file on firmware target 0 I get an upload failed message. Looking at the home assistant logs I see this message:
zwave_js_server.exceptions.FailedCommand: unknown_error: Error: invalid zip data
Is there something wrong with the firmware files in github and on the firmware download site or am i trying to flash it incorrectly?
