Many times, suddenly dead board is caused by bad NAND; even when no SSD short detected.

Is the machine recognized into DFU?

"i have remove the 2 nand"
Just removed, or replaced?

SSD must start to work before the board fully boots.

i have just removed, not replaced
i test again with replaced tomorrow, but i thought that without the rams I could see 19V return instead of 5V

M1 requires previously communication with SSD...
