You must flash the chip with correct file...
Did you connect the 1.8V adapter correctly?
Post some pictures of your programmer and SPI chip connected.

Images attached below
Image 1 = everything attached and connected
Image 2 = Just disconnected the adapter and the blackboard on the position it was connected
Image 3 = The DOT on the IC is pointing to the DOT on the blackboard
did it exactly as we talked before

Seems that you've connected 1.8V green adapter in reverse way into CH341 programmer.
CH341 usually has marked the positions for 24X (EEPROM) and 25X (SPI) chips.

I probably didn't sleep enough; just checked my programmer now and saw your connection is correct.
Check continuity between SPI chip and 1V8 adapter socket.
Checked betwen SPI chip and that big IC on the adapter and all of the pin beeped continuity
I also checked again and there is 1.8v on pin 8
Whats else?
Try another programmer...
DFU restore...
Try revive first, if you still want to recover data; not always possible.

After ALL of this time and procedures
I did DFU restore with the BRAND new BIOS flashed with the DUMP you gave me
And we are back to the same behavior
The only thing I think is different is that now I can click on internet recovery mode and it starts to load but then it crashs and its in a LOOP

Do you think is bad SSD? Do you think does it have grey pads below it not allowing the NAND to function properly? Would you remove the NAND and reball it?
Or give back to customer as NO SOLUTION?

This looks like wasted time.
SSD works at least partially.
You can test it in target disk mode eventually.
