Convert to Tasmota failed from 1.4.4 - Shelly Pro 4 PM

[cDev1987]

Hi, today i received my Shelly Pro 4 PM and i tried to flash Tasmota fw to the Shelly, but after update it came back to my Wifi Network and i still see the Shelly GUI. I read the thread where many users reported to have a bricked device after update from 1.4.2
From 1.4.4 it seems that the update is not possible, but device is not bricked.

20241011-114451/1.4.4-g6d2a586 tried mgos32-to-tasmota32-Pro4PM from latest release 3 weeks ago

I saw there is pro 4pm v1 and v2 - is there a difference wrt flashing Tasmota?

Device name: Shelly Pro 4PM V2 Device model: SPSW-104PE16EU

"data": "shelly_update.cpp:421 FW signatures: want 07 got 00", The log shows everything okay. We don't have signed firmware. The message is always there when using the convert script The log after this message is the interesting part

Hi @Jason2866 thanks for your feedback. Anything else i could check or i can try? Or is there a way to get more debug data from Shelly device?

Without the device idk how to find the reason for.
