Flash boot code Digital Signature Verification failure!

[kailash]

Can someone provide a solution for Seagate 2TB Mobile ST2000LM007 PN:1R8174-570 FW:EB01 Site:TK FW:EB01 DOM:15NOV2022 PCB:100835923 REVB
Drive comes to ready with full ID but none of the sectors are accessible.
ROM is NOT readable through the terminal. I wrote unlock patched to the ROM externally and yet I can't send the UNLOCK signal through the PC-3000 terminal to the drive.
I used a matching DONOR pcb with transferred patient's ROM but I get this error message:

and the drive doesn't even turn on.
Here is my question, is there a way to change the Digital Signature of the patient's ROM to make it compatible with DONOR pcb controller's Digital Signature?

Thank You!

Are you sure you copied the patient's ROM to the donor correctly? Why did you change the PCB?

[kailash]

I suspected there might be a problem with the PCB, so I replaced it; could you please fix my ROM? BIt's possible the ROM didn't copy correctly when I was copying it.
I would be very grateful to you.,
