Flashing Shelly 2.5 to Mongoose OS via USB-COM (Currently HAA Installed)

[genius23pl]

Hi everyone,

I need help with flashing my Shelly 2.5 to Mongoose OS using a USB-to-Serial (USB-COM) adapter. Currently, my device is running HAA firmware, and I don't have the original Shelly firmware to revert to.

What's the question?
Cabling?
If you want to flash just use mos-tool with the downloadable zip files.

I was just getting to that, but I did it differently - I had one shelly 2.5 with the original shelly software - I made a backup of it, uploaded this backup to all the shelly 2.5 drivers , and then did the upgrade to mongoose-os via OTA.
