Bro, Check your connection first and do not forget to post screen short not logs like this.

You need to solder the required pinout as shown in GPG EMMC Box.

Then, Connect USB cable to the device

Press the Power button of the device

Now, you start the operation that you want to do.



Note: color, doesn't matter. You will find the level on each wire. For example:

Red:--------->TRST
BROWN------->TDO
YELLOW------>TDI
Blue---------->SYSTAR
GREEN-------->TCK
Light White---->GND
Orange-------->TMS
