Story is WD WD10PURZ came with no BIOS chip, so trying to reconstruct from donor.
PCB 2060-800006-001
Using MRT
- Found donor, same PCB, same main controller, 2 weeks apart
- Backup donor ROM and resources
- Transfered donor ROM to patient
- Patient gets ready, recognizes right family, obviously no SA access
- Tried to load donor loaders to RAM (gives me 1B, 411, 5C, 10, 11 choices when i choose folder)
- Loading each loader with "Persistent cover" method works (allways loading 11 last)
- Loading with "write to RAM" method gives error "Err(Write Data Fail)"
- Head test says heads are OK
- Can´t get module list and cant find module 0x129 by trying to search for it
- Sometimes i can get loader 0x1B to "write to RAM", but only 0x1B
Any tips i could try?
I don´t think this PCB model is locked, right?

Why not just use the donor PCB?


If it is locked, then should you start and work with the donor PCB?
