I'm not sure should the bundle be FB02? I think it may be FB03 - that's what I try. The 5.8.10 Update package is FB03 and that's obviously what the Kindle likes. Would it work with FB02?

Also, the factory firmware contains user data image. I don't know should we put it in the update? I mean, the Kindle should already come with this out-of-the-box.

Hi, the process I was talking about was specifically about trying to build an FB02 package that would work for PW3-32 Manga mode.

The FB03 packages must be signed with amazons official signatures.

The FB02 package is not signed itself, but still the individual parts need to be signed properly.


the FB03 packages of 5.8.8 and higher are what apply the "downgrade protection', thats why we need to keep using the FB02 packages.


So my goal was to extract the 5.7.4 'rootfs' with the 5.8.7 uBoot and uImage.

I tested with 5.8.10 uImage, but that is a bad idea, and I had to recover with serial port. Because only half of the new protections were available. ( I could have upgraded to 5.8.9 or higher instead of recovering with serial, but then I would not be able to downgrade again without serial - it wasn't bricked, I just could not re-install the same update. )

5.8.7 appears to fully support manga model, so I went with that one.

This still only works if people have the OS that is allowed to downgrade, 5.x 5.8.7, and 5.8.9.0.1 ( and other fresh out of the box images ).

If you are willing to try this 'frankenstein-update' I have it available here.

Code:

Reminder - this is a frankenupdate. I don't think it will brick a PW3-Manga, but there is always a small chance.

The name still says 5.8.10, but it should be better named "5.7.4_5.8.7".


@anhyeuviolet

What version is running on your manga model now?

Would you be willing to test this?
