USB Networking is one way to do this. You could also install kterm and access it from the KUAL menu. This will open a terminal window where you could enter "ls -l /sys/class/backiight/" and see what the response is. As NiLuJe suggested, he is interested in a pseudo-filename that can be used to control the backlight. From the behavior you are seeing, it sounds as if the PW4 uses a different name for this control interface than the PW3 does.

I hope that is helpful.

Thank you Dave for the guidance.

NiLuJe, I could not figure out how to take a screenshot or copy this, so I took a picture (attached). Is this what you are looking for?

This worked for me:

"echo 0 > /sys/class/backlight/bl/brightness"

"echo 1882 > /sys/class/backlight/bl/brightness"

I based it off the post from here:
https://www.mobileread.com/forums/sh...d.php?t=288547


Those were the min and max when I use the slider bar to go to min and max.


There is also a device called frontlight, but I cannot tell what it does
[CODE]
[root@kindle frontlight]# pwd
/sys/class/misc/frontlight
[root@kindle frontlight]# find .
.
./dev
./power
./power/control
./power/runtime_active_time
./power/autosuspend_delay_ms
./power/runtime_status
./power/runtime_suspended_time
./subsystem
./uevent
[/CODE

@coplate: Thanks, that should do the trick .

Yeah, there's an extra thingy to toggle the nightmode-friendly frontlight behavior (among other things, possibly).

Apparently, they have added in more 'downlgrade' protection, in addititon.

This means that if you have upgraded to 5.10.0.2, or have a device that shipped with that, then you cannot downgrade to 5.10.0.1; You have to use the factory version that matches your installed code exactly.

This post is based on what the people who had with 5.10.0.2 reported, and I have updated y device to that version and confirmed.
Code:
181120:161817 OTAController[1270]: E FB02Bundle:FB02BundleValidationFailed:reason=IncompatibleVersion,deviceVersion=3341680009,bundleVersion=3337430015:IncompatibleVersion version
181120:161817 OTAController[1270]: E BundleValidator:validateBundle:valid=false,filename=/mnt/us/update_kindle_all_new_paperwhite_v2_5.10.0.1_factory.bin:Removing update file
I attempted to remove the SP01 header, and then re-write the bundleVersion, but no luck, FB02 images Have to be signed now.

Hopefully this may encourage people to find a new jailbreaking method, that doesn't rely on the factory images.

Misc. notes

The contents of the version.txt file on my Kindle when received was:
Kindle 5.10.0.1 (333743 015)
Note the 'space' where the first post lists a 'zero'

First post, step #2, you can also 'restart' into the factory update package.
Just be real careful not to hit the 'reset' which is next to the 'restart' on the settings menu.

@coplate: Huh, that's interesting. They indeed started putting & honoring a target OTA field in there, as well as wrapping them in a sig envelope... -_-".

I updated KindleTool to honor that (defaulting to the Rex behavior, meaning that field will have bogus info on earlier packages in convert's output, and create will wrap FB02h2 packages by default).

Question, if I update the firmware on the PW4, do I also have to reinstall the hotfix after update?

Thanks!

No.
The "bridge" code auto-reinstalls itself and the other parts of the "hotfix" that might have been affected by the update.

I didnt read this thread before I switched on my Kindle. I bought it 2 days ago, and connected to WiFi immediately. I'm not sure if it updated itself or not, but it has firmware 5.10.1.2 currently.

Is there really no way to go back to an older firmware? I have not really been following this scene in the past, but do updated factory images get released fast? Should I just return it and buy another?

Unfortunately, no known method of downgrading for now. You best bet is to buy a new Kindle.

Thus far, latest known shipping firmware is 5.10.0.2.

Return it and get another one. It is very hard to get the USB connector, connected; I can tell that from over here.
OR
Use the serial port jail break method.

Hmm...
We probably should edit in some additional info about the new file system structure in the serial thread.

Hello, ask, I installed the KUAL plugin at https://www.mobileread.com/forums/sh...&postcount=304, then used this plugin to install kpvbooklet 0.66, and then downloaded the KOReader Kindle in November 2018. The package, copied to the root directory of the kindle, open the KUAL plugin to see KOReader and his function options, but click on the file to browse and open the document can not be used, always flash back, copy the epub e-book to the Kindle root directory In the document, it will not be displayed after disconnection. I can see other people's posts. If KOReader is installed normally, you can see the epub e-book on the homepage, but my KOReader is always unavailable. The Kindle firmware is 5.10.0.2. There is a problem in one step, how to fix it, thank you!

There is no known, consumer, 5.10.0.2
That must be the "factory" 5.10.0.2 that you used to jail break the device.

The "factory" firmware builds are intended for use IN THE FACTORY by the QC process.
None of our add-ins where ever intended to run on a "factory (use only)" firmware.

Update your device to the current, consumer, firmware and then try again.
https://www.amazon.com/gp/help/custo...4HPVAW86CHYHKS
If you did not skip the "hotfix" package installation, your jb will be protected during the update of the firmware.
If you did skip the "hotfix" package installation, install that before updating your Kindle firmware.

After the firmware update, re-install all of our add-ins, being certain to follow the directions for each.

You do have to push all of the buttons in the correct order, or things will not work correctly:

(Do not try that at home if you have a weak left hand.)

Hello,

first of all, thank you very much for your efforts. I was able to jailbreak the Kindle PW4. Unfortunately, I have to send it back to Amazon. Can somebody please tell me how I can undo the jailbreak and reset to factory settings?

I followed the tutorial in the fist post. My firmware version is 5.10.0.2.

Thank you!
