Hello.

Have You soldered the wires to PCB (ISP connection)? Or You have removed eMMC from PCB and soldered the wires directly to eMMC contacts or use proper eMMC adapter?

Please check soldering of all wires, make each of them as short as possible and try to connect again. Try to set higher Voltage level (2.0-2.4V), try to set different Bus speed values and connect the device. Post here the result.

Also the problem may be with eMMC chip.
