I've been given a Kindle 4, 2011 (silver paddle edition), running firmware 4.1.3.
I've factory reset the device, and ran jailbreak kindle-k4-jailbreak-1.8.N-r16252. That went through no issues at all, and I see the book.
On the below, I have read the instructions, ensuring files are to my specific device
Installed kindle-mkk-20141129-r16572. That seemed to install without any issues - I didn't see any errors.
Installed KUAL-v2.7.21-g3928582-20190724.
I see the KUAL book in my library, I run it, and get:
An error occured:Main class instantiation threw a RuntimeException. Please contact the developer.
Reading this can happen on the first run, I waited 30 secs and run again, got the same message. I've checked the folder structure of the kit, and don't see the extensions folder from what I've read.
I re-run kindle-mkk-20141129-r16572 just to make sure, didn't do much though.
At the moment, I've done another factory reset and left the kit as it is as wasn't too sure what else to try
This is slightly off-topic, but I thought it might be of particular interest to Kindle hardware hackers.

But Updata fireware to 5.12.2, my Kpw4 lost JB，the";log mrp" do not work.
Before Updata，I flashed the newest hotfix （2019-Oct-11 23:23:06）using '；log mrpi'. After the operation, I found out that it is a wrong operation. the ';log mrpi' has't work. But I can still perform the correct operation.
I flashed the newest hotfix （2019-Oct-11 23:23:06）using "Update Your Kindle" to my kpw4. it work，but ";log mrpi" still don't work.Finally I put Factory JailBreak (Factory FW) in my kpw4 and update。After reboot，My kpw4's FW revert to 5.10.1.3，and '；log mrpi' work.
Hello, can anyone help me with this problem? I'm trying to jb my Kindle but when I try to boot into diagnostics mode it gives me a "data abort" error and boots normally. The Kindle (KT3) is new and works just fine. No other kind of hacks or modifications have been (nor even tried to) performed on it. I have searched the forum and on google, but I can't find anything. Here's the relevant part of the log:

I feel my Kindle works less and less on a full charge, but maybe I just read more.
Anyway to verify that I've created a simple script to monitor the battery charge and screensaver events.
echo "$SOURCES" | lipc-wait-event -m -l battLevelChanged,goingToScreenSaver,outOfScreenSaver,charging,notCharging | while read event; do
echo [`date`] $event >> $LOGFILE
done
It uses lipc-wait-event so should have no visible influence on the battery live.
Example log print:

I'm attaching also KUAL extension to enable the script. It'll run until the restart, creates the log in battery.log file in the root folder.
I know there are lots of jailbreaking threads, and I'm not looking for ways to jailbreak my Kindles (it's not possible yet with mine, even if I wanted to).
What I'm looking for is experiences with jailbroken Kindles. Why did you want to jailbreak? Is it only for the screensavers? And now that you've jailbroken your Kindle is it really what you'd hoped for?
And is it easy to maintain the jailbreak? Or do you regret is because it's a lot of hassle?
Sorry if this has already been asked. I tried to read almost all the jailbreak threads, but most concentrate on the technical stuff, and that's not what I am looking for.
I just want to know if it's really worth it, and if people regret jailbreaking their device because it's not what they'd hoped. Or it's too difficult to maintain the jailbreak. Or if they kind of really wanted the new update (because of features?), but can't because it's now jailbroken.
I have this voice in the back of my head saying I should jailbreak once it's possible, but on the other hand, it it really worth it? If it's only for the screensavers, I can live without those.
So what are your experiences with jailbroken devices?
I really envied the PW2+ feature of displaying current time while reading.
There was this extension called showtime by @Hanspeter https://www.mobileread.com/forums/sh...d.php?t=282590 but it had two flaws:
- it was using default eips font for printing the time
- it was not updating on minute-change, just when the page is turned.
And as I've recently discovered (masochistic?) joy of writing bash scripts here's another extension to do so.
It should have no influence on the battery, as the main process uses lipc-event-wait, and child processes are being suspended when no clock display is needed.
It has still few bugs that should be corrected soon:
- clock show once when the script is started (it disappears after titlebar refresh)
- sometimes clock persists after exiting a book (it also disappears after screen refresh)
- in rare occasions clock is not displayed properly (some digits are missing)
The script currently will work for PW1 only, but should be easily portable to KT (resizing digits+finding new XPOS/YPOS values).
Hello! I'm im very new to the Kindle hacking scene and really messed up:help::help:. I put my Kindle 4NT into developer mode and now its stuck. The 5 way pad wont move anything, the power button wont do anything and the light is the only thing that alive. I thought about letting it die then trying but IDK about that one. I really wanna just get some nice screen savers and get some cool stuff. IF you can Help that is great! I wont be here to much but you can contact me by my number - 7864429374. text only please thanks.:thanks:
just a request for some advice. I'm a bit of a cheapskate, I don't want to pay for sponsor offers removal if I can avoid it. I have a Kindle Basic KT3 with the firmware 5.9.2.0.1. If I recall correctly it has never been online, although I might be wrong. I made the "update.bin.tmp.partial" dummy folder in the kindle's visible partition's root directory. If I go online with it to browse wikipedia, will I get the sponsor's offers? Is there a way to avoid them without paying? I like the default screensavers it has now (just some images showing off the E-ink display's quality), and my previous kindle had some adverts there which I'd rather not have.
I don't wish to jailbreak it, the hardware jailbreak seems like an awfully risky. Should I just keep it offline forever?
Hi,
I've come to inherit a Kindle PW1 which is bootlooping on the tree screen. I tried all the basic ways to get past it with no success so connected it to serial to have a look. It appears to be bootlooping because of this error:
When attempting to access the kindle's fat32 partition on the computer through recovery or diag it appears to have no filesystem as the computer asks to format the drive before using. When in recovery however, Export FAT Partition causes an immediate YKNR screen.
I was going to try flashing everything again via fastboot but am unable to get the factory images from the original website that gets used here and while I can download the update officially from amazon, I am unsure if I can use that to do what I want to do.
If anyone has any ideas where I can go from here that would be great!
Thanks
IM BACK! my problem with it being bricked had been solved. But now that i have gotten to a beginners intermediate, i wanted to try SSH and usbnetworking. I have kite installed and it works but when i follow the docs here: https://wiki.mobileread.com/wiki/Kin...USB_Networking
and i get stuck on :"Find the Local Area Connection # with small text "Unidentified Network, RNDIS/Ethernet Gadget" I dont see that. if anyone could be so kind to help me and also give me some apps to download for kite that would be great.:thanks::thanks:
THIS WORKED FOR ME BUT I DON'T KNOW IF WILL WORK FOR YOU. DO NOT HOLD ME LIABLE TO ANY DAMAGES THAT HAPPENS TO YOU :eek::2thumbsup
If you are stuck on the diags screen after trying to click exit, don't call Amazon unless your trying to get coupons off of them. Instead use MFGTool.exe to set your kindle back to home screen. It may or may not tell you to charge it b/c even if its frozen and you charge it it doesn't work, IDK why :chinscratch::blink:. But after that, you should be able to go read! :2thumbsup
MFGTool file linked below.
Amazon now has a Kindle whose description reads like the PaperWhite description used to read. They labeled it as 'Kindle 10" in the specs section of the product description. The new PW ($30 or so more) is waterproof, more storage, yada, yada, yada. I don't need all that stuff.
I would prefer to jailbreak it so my actual question is, "Is there a JailBreak available for this new device?"
I have a general understanding what a jailbreak actually is - as far as I can see it requires to find a vulnerability in a "binary" (or even better - in the system) that anyone can exploit (if he knows how). I also have some knowledge and experience in reverse engineering.
So, the main question is - are there any guides on MobileRead (or anywhere outside it) on how to start with writing kindle's jailbreak and where to look at? Could someone give any directions where to start? If I would be able to find a way to bypass a security in a firmware, how to integrate this knowledge with existing infrastructure (e.g. what should I do to make it possible to install KUAL, etc)?
And I know, this process requires a tremendous amount of time investment :builder:
Step 1: Download PW3 factory_PW3_5.9.6.1_initial firmware
Step 2: # Home -> Menu -> Settings -> Menu -> Update Your Kindle # Confirm # Wait
Step 3: Transfer main-htmlviewer.tar.gz to main directory
Step 4: In search type ;installHtml
Step 5: Transfer Update_jailbreak_hotfix_1.16.N_install.bin
Step 6: # Home -> Menu -> Settings -> Menu -> Update Your Kindle # Confirm # Wait
Upon restart I cannot downgrade the firmware (I want to go back to 5.8.1)
It says Update Error An invalid update file has been loaded onto your device.
I cannot install KUAL-v2.7.21-g3928582-20190724 -> it never shows up in MY LIBRARY
What did I do wrong?
Thanks in advance for an helpful tips
