Heya,
Did you ever get this resolved?
I am trying to understand how to flash the original firmware back to a Shelly Dimmer 2, but the files I can download from here (or http://archive.shelly-tools.de/) contain a bunch of bin files and a a manifest file that seems to map the files to different ROM locations:

So not sure a normal flashing tool (like esptool) would work to upload the binaries correctly.
Can anyone from Shelly help here?
