I am having trouble writing openbk OTA and through serial.

OTA using cloud cutter I get an exploit didn’t work error. Tuya shows the module on firmware version 1.3.5

Serial I get a write error

Added after 6 [minutes]:

Just realized looking at my screenshot I have the wrong firmware selected for write. If you use the UART it should work.
