Shelly Plug Plus S v2 Stuck in Safeboot

[sroebert]

Two weeks ago successfully migrated several Shelly Plus 1PM and Shelly Plus RGBW PM modules to Tasmota without any problem.

Last weekend (feeling confident about the process) I tried the same with two Shelly Plus Plug S devices (V2 specifically). After performing the safeboot migration the device was not accessible through the web interface anymore, even though it was still connected over wifi.

I left this for about 15 minutes. After rebooting the device by unplugging it, I could access the web interface again. It turned out to be booted in safe mode. It was not possible to get out of this. I tried updating the device, restarting, resetting flash, nothing helped. It seemed to be the same issue as: arendst/Tasmota#19414

If it was one time and I would not have converted any other devices, I would think it would be a random mistake, but it happened for two devices in a row. Is there anyone who has any suggestions on what could have caused this or how to prevent/resolve it?
