I found this guide: https://www.dolphindatalab.com/how-to-r ... rd-drives/
Unfortunately MRT (that I am using) does not support this ST3000NC000 model.
Anyone who has done this that can share an unlocked ROM?
Thanks!

Perhaps the OP could upload a locked and unlocked ROM for a supported model so that we could see how MRT does it. Then perhaps we could make similar changes to the ST3000NC000 ROM. We could also see if PC3K makes the same changes.

Sadly, that won’t work.
An “unlocked” ROM using the unlock feature from PC3000 (I can’t speak for MRT as I don’t use it, but as it’s as a ripoff of PC3K then I can assume it’s the same/similar) will prompt a code in terminal (different each time) for a corresponding code from the tool before it unlocks and proceeds to initialise the drive.
Without any code being entered, the drive will just sit there BSY waiting for the code. If an incorrect code (or just “enter” a couple of times) it will initialise but still locked.
The unlocking “feature” is generally only used to allow the user to fix any firmware issues (to edit ID and disable background tasks etc. for example) before reverting the ROM back to “locked” so the drive can be cloned or whatever needs to be done.

Could you please provide a second unlocked ROM (for the same original ROM)? We could then compare the two unlocked ROMs to see where the different "codes" are stored.
