How to get the original PS4 kernel image (not a memory dump)?

[ultimaweapon]

Not sure if this is even possible. The problem with memory dumps is it is already patched when jailbreaking. Some pointers also mess up, which cannot follow its reference.

@VocalFan can you help on this? I saw you have some contact with the scene not sure if you can ask them to see if this is possible.

I asked them, waiting for reply.

You'd need PUP keys. @ultimaweapon

• Or another way to decrypt the image.

[FluffyOMC]

Oh, it's impossible. Even if you had the decryption keys, you'd need a hardware flasher/dumper to get the kernel image.

[FluffyOMC]

You would require the PUP decryption keys, and a hardware flasher/dumper to get the kernel off the device.

So the dump from the above tool contains the encrypted kernel? Is it possible to get the key from the console?

[FluffyOMC]

Err... Not that they or we know of yet.

[ultimaweapon]

So the conclusion is it is impossible to get the decrypted kernel image for now?

Just wondering why we cannot use the same method for decrypting the PUP file with the kernel despite it using the same key.
