Hello

Unfortunately, EMMC in ISP mode is not supported for this device. It means that we haven't tried yet to do something with this device.

Also, please, send us photo of how did you solder(please, show us phone and box connection).

In case, you sure that this pinout is right, you can try to connect pull-up resistors 150 Ohm from VCC to DATA0 and from VCC to CMD.

On the other side, if it is not correct, you should find proper pinout.

ATTENTIVE!!! it is prohibited to turn on device with this resistor!!! This resistor is only for connection.

Before you turn on device, unsolder this resistors!!!
