If this is the correct ROM dump, then this is a new architecture with no RAP, in which case the RAP data must be SA-resident.
Are you aware of the following?

as you know, these helium drives are not supported by any DR-Solution. But with a few Seagate Helium Drive Models the F3 Utilility of PC3K is capable to edit headmap in ROM. It is unfortunately not possible with this model.
This Drive makes constantly calibrating sounds and sounds like it will become readable. It gets full ID but as i know, this is only ROM related. After some seconds it gets ready state, keeps spinning, but there is no sector-access or anything else possible. Terminal Output as follows:Boot0x0100MAA0053SN03Motor startedHeads loadedHPSR[LBA=0x0000000000000105]N??+

When i load the ROM-Image i get "WARNING! Segment used space check sum is invalid!" message of PC3K. When i patch the ROM to unlock techmode, then drive doesn't spin on and Terminal shows constantly:Flash boot code Digital Signature Verification failure!
Flash boot code checksum failure!

So question is: please see the attachment, maybe there is any chance to edit headmap or unlock techmode...?! Or somebody wants to share their experiences regarding headswap for this model?! Any chance without reinsert helium and seal it again?
Thanks in advance.
