For firmware EMS TP.HV320.PB801 there are points for connecting RT809H ?

If you find the points but still failing to read or write. Disconnect the Clock resistor that links the Nand Chip & the CPU. Connect the (White) clock wire towards the EMMC chip (Nand). I have managed to read & write a lot this way.

Sorry, we don't have. Or you can take apart the EMMC, and you will find the points.

He applied one 3.3v power to UD5, writes 016:  VCCIO: 3.3V
017:  Read timeout.
Do I need another 1.8v  ?

The 3.3V Supply should be enough or use original PSU
