Reverting a Shelly 1 back to original software

I have several Shelly 1 devices that I flashed with ESPhome. I’d like to revert these back to the original Shelly software. I can’t find a download on the Shelly site for the original software or instructions on how to do this. Does anyone know if it can be done, and if so, how?

i haven’t done any shelly flahsing, so this is just an idea. Is there a way to “backup” the original before flashing… the you just need to get your hand on a new one and back that up and re flash the others?

See if this is useful

Thanks!

I think I can change the Shelly from ESPhome to Tasmota via a serial connection then use the Tasmota OTA Web Server update option with that link you shared to put the Shelly software back on. I’ll report back if that works.

any luck finding the shelly software?
