Where to find original Shelly 1 firmware?

Hi,

I have been looking around the support website, but I can't find the original firmware for the Shelly 1. Could someone point me to the right file?

Thanks a lot for your help

Hello

Many thanks for your response; however, I forgot to mention that the Shelly device had been flashed with Tasmota. I want to revert it back to Shelly firmware. I tried the link that you suggested, but I get an error.

Any hint?

Best

You saved my life (or at least, my Shelly's) Many thanks and happy new year
