A2141 stuck in recovery mode.

Hello.
I have a customers Macbook Pro A2141 that appears dead, no fans or display but trackpad does click.
Customer reported that it worked fine last use, and that it hasn't been dropped.
I removed the back cover, and, apart from dust, no other sign of any liquid ingress or other issues.
It reports 20v on all 4 USBC ports, in both orientations.

When connected to another mac (A1708 running Ventura 13.6.5), Apple configurator (2.16) shows the MBP to be in recovery mode.
I selected "Advanced-revive device", but it fails with the following message:
"The system cannot be restored on this device amrestoredomain error 6.

I tried the revive three times, with the same error each time.

I put the unit into DFU mode, after some difficulty, and retried the revive again, three times, but it also fails with the same error.

I've tried with a couple of different USBC cables just in case.

The customer would like the data of course.

Any suggestions would be greatly appreciated, once again.

Thanks once again 2informaticos.

It doesn't look good.
PP2V5_NAND_SSD0 appears shorted to ground.
Measured in diode mode, red to ground:

L7330 0.038

LA850 0.040
LA860 0.032
LA870 0.032

LA950 0.023

LA710 0.01
LA720 0.01
LA730 0.01
LA740 0.01

I guess I'll try injecting a low voltage and hope something other than the NANDs heat up.
