Option, no need to disolder the module

I've been programing the modules without disordering.
Just remove from the LCD board from the power module, connect the programing pins, gnd and 3.3V, ensure a good power supply able to supply 200mA or more, and that is enough.
With the lcd module floating on the air the tuya mcu is usually stuck in reset so it does not interfere with the programming.

See the photo i updated above. It works for me :)
BTW: On your photo there seems to be a solder link between TX and RX?
