Description
Do I need to do something special to flash the original firmware back?
I have a device powered by an TYWE1S, did the full tuya-convert process successfully and got tasmota running on it. But tasmota was not understanding the second MCU device is not supported so I wanted to flash the original dump back.
I hooked up an RPI and flashed it back.. it is outputting stuff on serial so something is working but I'm not able to start the pairing by pressing the button for 5+5sec, led is not even flashing.
Unfortunatly I did not dump it via the serial before I started..

Research direction
Start with the VTRUST-FLASH output in the issue and the reported serial behavior, then review the restore and pairing flow used by the project. Done means determining whether the original firmware can be restored on the TYWE1S device and whether the button and LED pairing behavior returns.
