Shelly 1PM back to original firmware

    Hello,

    I did install tasmota on my Shelly 1PM , but something not working as expected. However, because I not sure is the problem into the firmware or it is hardware problem - is it possible to back my shelly with original fimware and how ?

    I would be very interested in how to do this too. I bricked one of my Shelly1 PMs and I would like to flash the firmware back on it. I have the firmware to restore it but what is the best way to flash it on to it? Can I use some type of flasher and connect to the GPIO ports with a serial adapter to flash it?

    To reflash OTA from tasmota to shelly (mongoose) follow this procedure:

    If the device is bricked In order to flash using the gpio pins you need the correct bin file, a ttl to usb adapter and use a program like Tasmotizer or Tasmota py to upload the file
