What if you initialise the donor's NAND after the patient's ROM is installed? Will the NAND be reinitialised with the patient's adaptives? Hopefully you won't have two dead drives.

I dont undertand how to do

If the PCB then works on the patient, perhaps it would be prudent to initialise the NAND again on the patient HDA???

I have made it also. >O I giving error on terminal if try this command with nonworking drive.
Also tried when drive working with foreign ROM. I dont remember well what was the log. But could be normal log as I remember

Does that mean that all the donor's adaptives (CAP, RAP, SAP) are backed up in NAND? Does it also mean that a bad ROM can simply be substituted by any donor ROM?

Tried same version 3 another different Rom.
All of them working. Accessing to drive and data.
Strange discovery.
But I cannot accessed customers data yet.

I would not call it a backup, it is the primary working copy there...
