Rosewood family rom corrupted

[Abdur Rahim Sopon]

Hello dear members,

We received an A5 2TB HDD with corrupted ROM data. The HDD was sent to us by another data recovery company, and they provided us with this ROM backup.

Is it possible to rebuild or repair the ROM data from this backup?

Any advice or suggestions would be greatly appreciated.

 

[compos mentis]

I have had a quick look at the ROM and I cannot find any obvious problems. Do you have a terminal log?

That happens when you transfer the ROM to another PCB, or when you write
an unlocked ROM to the original PCB.

Also, I now notice that the CAP module is empty.

[Abdur Rahim Sopon]

yes we see this message when we swap pcb and unlock rom write back in new hdd MF after 2020.

But this HDD MF is from 2018.

I think this HDD issue stems from a ROM issue.

Does the SAP S/N (WDZH0MPF) match the label?

Can you show us a photo of the label and the component side of the PCB?
I'd like to compare date codes.

I found this S/N in the extra space at the end of the ROM -- WES0N3XC. I
also found a copy of the SAP which does not match your actual SAP module.

WES0N3XC is a Mobile HDD 1TB, Model Number ST1000LM035.

Hello 

compos mentis

Yes, this is the original info from the HDD.

Is it possible to repair the ROM module using a donor ROM?

We would need to determine what the other shop did. To this end I would
need to see photos of the label and component side of PCB. You still
have not provided this.

The ROM has a digital signature. If the MCU has a security/encryption
key, and if the PCB has been replaced, then we would need to find a
donor PCB with the same firmware version, and then patch the patient's
adaptives into the donor ROM.

The result would be ...

  patient HDA

  donor PCB and donor MCU with donor's MCU key

  donor ROM with same code version as patient but with donor's digital
signature

  patient's adaptives

Your PCB has the donor's ROM with the donor's RAP and SAP in the "extra
space" at the end. We can only hope that the primary RAP and SAP are the
originals. The CAP is empty for some unknown reason.

We need to examine the PCB to see if there is any evidence of soldering.

I have attached the donor's SAP and partial RAP which were carved out of
extra space.

[Abdur Rahim Sopon]

I found they solder only rom chip.

That's a difference of 2 years. It may be that there were no updates in
2 years, but it does look suspicious.

Also you should compare serial number on lid 

With serial sticker on the body. 

They could mix up the lids.

Rom also has serial number of drive and pcb's serial number.

The manufacture date is 13 Oct 2018

The date code on the ROM is 1820. That's week 20 of 2018, which is two
months earlier than the SDRAM. This looks suspicious.

[compos mentis]

AFAICT, the PCB S/N should be stored in the CAP, but the CAP is empty.

[pbzcbf...@gmail.com]

I don't know if this is a red herring, but I'm finding firmware versions SDM2 and SBM3 in the first BOOTFW container.

[compos mentis]

When I search for SBM3 at HDDSurgery's firmware database, I get only 1TB
results.

When I search for ST2000LM007, I don't see any SBM3 firmware.

It seems to me that the ROM comes from an ST1000LM035 with SBM3
firmware, but the adaptives are from the patient. I assume that the PCB
is also the patient's PCB, with patient MCU, which would account for the
signature clash/error.

[compos mentis]

Do you see something like this in terminal (ST4000DM004-2U9104 example)?

The ROM is from a 1TB donor, but the adaptives are from the 2TB patient.
That's the only thing that makes sense to me.

I would ask the other shop for the original ROM. Also ask them why the
CAP is empty.

If they don't comply, then you will need to buy a 2TB donor PCB with
SDM2 firmware that is compatible with the SA, and then transfer your

adaptives into the donor ROM.

[Abdur Rahim Sopon]

I asked; they said they read this backup under this condition which is lying i am sure of.
But somehow they messed up the original ROM, or they don't want to send me the untouched main ROM.

I have the same donor firmware and HDD

I read and verified both.
