ST6000DM003 Rom Corrupted

[apuliarecovery]

Hi, I have a Seagate ST6000DM003 with PCB 100870247, the PCB is faulty and the disk doesn't start.
After various tests I came to the conclusion that Roma is corrupt. Do you know if there is a way to rebuild it?
I attach the file saved after desoldering it.
help me

The ROM has a digital signature which is matched to a key in the MCU. If you transfer the ROM to a donor PCB, the donor will complain of a mismatch in the digital signature. Is that what is happening?

Can you upload the donor ROM?

What do you see in the terminal log on patient and donor?

yes,
here rom donor

By placing the patient ROM on the donor PCB, neither the disk nor the registers are activated.
While with the donor pcb and its rom the disk starts, you read the registers but click.

Your donor also has a digital signature. Try importing your patient's adaptives into the donor ROM and then write this hybrid ROM to your donor PCB.

If you then encounter a mismatch between the donor's ROM code and the patient's SA overlays, I could import the donor's signature into your patient ROM. That would be the better option, anyway.

If you don't have the tools to do this, let me know.

BTW, is your patient PCB faulty? What was the original problem with the drive? In some cases it may be easier to repair the PCB.

The disk would not turn on, I found some faulty components, which I replaced without success.
I attach the photos to you
If you have the opportunity to try to rebuild the rom, then I write it with the programmer.

bad components

Try these.

First try "Rom_ST6000DM003_creative_orig2_donor_sig_goodCRC.7z". This is my attempt to import the donor's signature into the patient ROM.

The other is my attempt to import the patient's RAP, SAP and CAP into the donor ROM. I don't know if the IAP needs to be transferred as well.

Ok, thanks, everything is ok

Ok, thanks, everything is ok

What did you do? Which one of my ROM edits worked, if any?

Unfortunately the customer decided not to do the recovery anymore and withdrew the disk.
I didn't even have the opportunity to verify the changes you made (: ...
thank you very much for your availability.
