firmware.bin doesn't work

[EdnEddy]

Hi, thanks for your great script 👍 It seems to work fine on my Raspi 3B / Raspian Buster / virtualenv

List of available devices (v1.7.x) is downloaded, 2MB firmware.bin are generated, but they don't work. Tested for Shelly 1, 1PM and I3 on orig. Shelly and Wemos D1 - no AP @ 192.168.33.1

(I'd need a Shelly I3 backup image.)

Any help appreciated :)

Also would love to see it working. Need it for the Shelly button1 device.

The binary produced for me is also not working. I tried both 1.9.2 and 1.7.0 for Shelly1 (v3) SHSW-1. I also tried it on both an OSX host and an Ubuntu host with the same result. The image seems to be created OK and loads onto the target OK. However upon reboot I never see the shelly1 sending beacons. I even tried the factory reset sequence with shorting the SW pin to ground several times, but I never hear the relay clicking. Also including the binary it produced for 1.7.0 as SHSW-1_1.7.0.bin.zip. SHSW-1_1.7.0.bin.zip

My output is below with the "-v" option.

Here you can find some recovery fws, I think they were sent from Allterco to users who needed to recover their devices... https://www.shelly-support.eu/filebase/index.php?filebase/49-auslieferungs-fw/ Don't know if they works, there is also the fw for an i3. BTW, seems like recovery fw uses hwinfo_struct_defaults.json instead of hwinfo_struct.json.
