Western Digital wd50ndzw BIOS Chip transfer

[KristoJebus]

I purchase an unlocked donor PCB board online (2060-810067-000) which is the exact same model number as my damaged board. I used a hot air station to transfer the original BIOS chip to the donor board that I purchased. After reattaching the PCB to the and connecting it to my PC I only see "WDUnlock" in the folder.

Wondering if anyone could advise as to what I should try next.

AIUI, these unlocked PCBs allow access to the System Area (SA) where the firmware modules are located. After the necessary firmware repairs have been completed, the original PCB is needed to decrypt the user data.

What is the problem with the patient PCB?
