I did with the kterm and later I wrote a script for KUAL. It writes the file with the correct name to the root directory. SSH or kterm are not required.
My post on 4pda.ru
My script:
Yes, yes, yes.

The test conditions did not translate properly.
Your solution requires that the device already be jail broken.

The conditions tested was if the current jail break would work, as written, when the device was already running 5.8.10.
I.E: Without having already been jail broken.

He was wanting to downgrade a Kindle that does not have the jailbreak.

There seems to be a search bar command for the purpose, but testing has not confirmed that it works properly.

What does work properly is, go to this page:
https://www.amazon.com/gp/help/custo...deId=201307450
and follow the directions.

Your JB will survive, everything else will have to be re-installed.

Hi all, I've been doing more research today, and I think I have some to a semi-useful conclusion.

We now believe that 5.8.9.0 direct from the factory is also capable of downgrading to the factory images that we have a copy of.

I am willing to stat that I believe the following:

Quote:
Any software available at first-boot will be capable to downgrade to a factory image.
The reason I believe this is simple. FB02 software image is the only one we are ware of that does not require a signing key installed on the device. This is obvious, because form the factory, there will be no software key installed on a device, until AFTER the first software.

And the protections for this do not get applied until after a non first-boot software is installed.

If we were to get ahold of this 5.8.9.0 version, I would believe that it also would have file type of FB02.

So, I think this is good news for anyone buying new hardware of these versions that we do have factory images for, that it would not necessarily be limited to just the 5.8.9.0, but anything that may ship from the factory.

Again, this is just a guess, but I am pretty confident in it. At least unless amazon changes production methods to install an initial version, and then upgrade to another version.

After that, I placed “KUAL-KDK-2.0.azw2” to documents folder & placed “Update_KUALBooklet_v2.6.40_install.bin” to mrpackages folder. During run Kindle Launcher, it shows Error again. (See attached pic).

I did. I don't remember the details, but it did not work. Nothing bad happened, after applying proper JB Kindle worked as expected.

Say what?
Please include a link to the post.
I do not recall telling you or anyone to rename a file.

This is the situation now
Your info box says you have a PW3.
You do not need to run the booklet form of KUAL.
Once you install the KUAL document, you do not need to install the booklet.

Use one of the two.
Do not use both.
Your choice.

Pictures are nice, but what is in the log files?
We already know what an error message looks like.
We do not know what is in your log files.
Both KUAL and MrPI create log files on failures - inspect and/or post both.

Find the current firmware version number shown on the "Device Info" panel.
The period (".") characters are not decimal points, they are field separators.
Open the following spoiler and compare numbers as described:
  • 5.a.b.c.d : Is first number anything other than 5?
    This jailbreak will not work.
  • 5.8.b.c.d : Is number larger than 8?
    This jailbreak will not work.
  • 5.8.7.c.d : Is number larger than 7?
    This jailbreak will not work.
  • No numbers for the ".c" and ".d" fields.
    This jailbreak will work.
  • 5.8.7.0.d : Is number larger than 0?
    This jailbreak may or may not work. Unknown.
  • 5.8.7.0.1 : Is number larger than 1?
    This jailbreak may or may not work. Unknown.
  • Have you reached the end of this list without encountering a "will not work" number?
    Did not find a number commented as "will not work": This jail break will work.
  • Reached the end of this list, but encountered a "may or may not work" comment?
    Found a number commented as: "may or may not work".
    Then it may or may not work, try it and tell us in this thread.
    You can tell if it is working by how long it takes to perform the update to the factory, production line, firmware.
    Less than a few minutes? It did not work.

With the one special exception: Firmware 5.8.9.0.1 with build ID: (3175970011) - On which this jail break works.

...
I have successfully installed this JailBreak on my new Voyage (9013), which ran 5.8.9 initially (different build number ID, not 3175970011), even if 5.8.10 was out some days.
I have read about it on MR Forum (post of coplate) this theoretically could work as this was the firmware it was shipped with.
So I was able to downgrade to factory_KV_5.5.0_initial, following all the steps and finally I have a working JB, KUAL, KOReader, on a 5.8.10 firmware.

big thanks to knc1

If you are able to give us that build ID, knc1 might be willing to add it to the exceptions.

Like you saw on my post, I have a very strong conclusion that any version you get direct from the store will be able to be downgraded, as long as you do not let it do an update on wifi first. ( for now, until they change something ) But it would be good to get your build number for future readers if you still have it.
