I wrote an article about how to flash any tuya YX-WS01 (amysen, esicoo, others)
Tuya-convert doesn’t work anymore for this devices, so I had to open it up, trace the circuit and solder cables to flash. I didn’t see any guide for these devices online, it may help someone.
This is my first contribution, please let me know if I made a mistake posting here
Is there any update on this process? I received 4 if these plugs as a gift, but when looking at your link some of the links don’t go anywhere (such as the ones under tuya convert update). In case I got lucky with old firmware I’ll try the tuya convert process though.
