CMD timeout error -

1) Bad connection CMD/CLK lines, bad voltage, you need check connection and voltage
2) eMMC card fully dead, need replace

At ISP mode:
1) Try to reduce CLK Rate, select correct IO voltage as PBC, adapter
2) Try to add 200 Ohm resistors to adapter for old box as at Z3x pinout pictures note
