I think that a knowledge of ASM would be useful in data recovery. In my case, I learned Motorola 6800 assembler at university. For my second data recovery case in the 1980s, I wrote a tiny routine in Data General machine code to scan a Control Data HDD for directory sectors. These days some of my Fr...

Would you indulge my curiosity by uploading your LIM2 ROM and some other ROM? ISTR there are a couple of ROM segments at the end of the ROM which are modified during normal operation. Perhaps you could clear those segments?

I can see a few LIM1 and LIM2 versions of ST1000LM014 ...

Are you looking for the PCB or firmware? Are you sure your ROM is OK?
