You have to either sign the firmware correctly and then send it into the SSD with hdparm or Samsung Magician. Or you can upload it with JTAG.

ISTM that the firmware payload file is "RI_PM863_GA38.fwh". This file appears to be a 1MiB firmware image preceded by an 0x200 byte header. I would guess that you could strip the header and then download the 1MiB image with hdparm. The results may be catastrophic, though. Your choice ...

The whole 1MiB file has to be decrypted and sent to the SSD (the Samsung tools are doing both decryption and sending). If you only send the rest, not the first 200 bytes, the signature check on the firmware inside the SSD will prevent loading broken firmware.
The Samsung tools also check whether the firmware actually fits the SSD. If you use hdparm instead of the Samsung tools, this check is circumvented and you have to make sure that it is compatible yourself.

The file does not appear to be encrypted, nor are they Samsung's tools, AFAICT.

I've a question:

I have a device that reads a cfast2.0 since those are more expensive, I used a adapter with an SSD.
Once the adapter is plugged in, the device reads the SSD ID and since it does not match gives me an error that the "media is not certified"

Basically I want to fool the device changing the name ID of the SSD to avoid this message.

How can I customize the name ID of my Samsung SSD?

I would love your help with this.
