Hi,
Easy Jtag box eMMC pinout you can find in software tab:
https://gyazo.com/8208ddb0ddd7d58e652061f70e461d11
You can use eMMC adapter like this:

or external power supply for 2.8V and 1.8V
Best Regards

Hi.
As vikboston said best is to have an eMMC adaptor.
If u wanna try without Vcc and Vccq just solder GND, CMD, CLK, D0 and power on phone with the battery or connect charger then eMMC should have necessary power supplies.
