Shelly 2.5 will not downgrade from 1.9.3 to 1.8.3

  • Hi,


    I am using the Shelly Firmware Archive to try to downgrade one of my Shelly 2.5 to firmware version 1.8.3.


    I have tried it 3 times now, even after factory restoring the device as well and every time, the Shelly reboots with firmware version 1.9.3.

  • I have problem downgrade from 1.9.4 to back 1.77 because this one is working with homebridge (homekit) without problems.
