Making apps for the kindle paperwhite and kual

Hi. I would like to make some small apps on my kindle paperwhite. I have jailbroken my kindle and installed KUAL. I have read and researched about this topic, but I still find it difficult to begin.

this is what i know by looking in some of the extension folders:
- you can change the name of an extension in the kual app by changing the menu.json file which also runs the .sh files in the bin folder.
- the kindle can run bash commands.
- the kindle is a linux system.
- the kindle can run python? (I want to make a python app and test it on my kindle).
- I have read somewhere that if it can run on linux-arm-something then it can run on the kindle.

Is there a sort of hello world/noob guide or could anyone elaborate on how this works?

Kindle firmware version 5.7.2

I just noticed that firmware version 5.7.2 for the newer Kindle models is available for download from Amazon's software update page. Testing now.

ETA:
Quote:
The software update includes general improvements and the following new features:

A new Home screen layout, which features access to your recent books, your Reading List on Goodreads, and personalized recommendations from the Kindle Store.

A new Quick Actions menu that allows you to quickly turn on Airplane Mode, sync your Kindle, manage your light settings, and more.

Our new Dyslexic reading font.
First impressions:

I like that the home screen shows the book you are currently reading, but not much else about it. It can be turned off: Settings, Device options, Personalize your kindle, Advanced options, Home screen view (off/on).

There seems to be more fine detail in the screen layouts. Thinner lines, etc.

The background images for folders and personal document covers are gone, making them easier to read.

The book reading experience seems the same to me so far.

PW2 How shoud I properly clear VocabBuilder?

Hi, guys.
Sometimes I want to clear my vocab.db but I have 2 problems with this. Let me tell you what I do.

For clearing database I use sqlite3 and the following queries
Code:
DELETE FROM WORDS;
DELETE FROM LOOKUPS;
UPDATE METADATA SET sscnt = 0 WHERE id in ('WORDS', 'LOOKUPS');
VACUUM;
Everything is OK, the base is empty, but after some time I see that all words, deleted from the base are back. I know, that Amazon stores this base but I didn't know it'll give me back all my words in this case. But it is not the main problem

After a couple of deletions I detected that I can't delete anything anymore.
Sqlite3 gives me the following error.
Quote:
Error: database disk image is malformed
Question 1: Are my queries correct? Should I add something more?
Question 2: What do I do wrong? Why my database got malformed?

At least for the PW-2, PW-3, KT-2, and KV
http://www.amazon.com/gp/help/custom...deId=200529680

Hmm...
That replaces the 5.6.x 'infection' with who knows what other bag of worms.

At least they describe a lot of new features for it. ;)

The PW-1 is still listed as 5.6.1.1 and the KT remains untouched by 'progress'.

Native Downgrading from 5.7.2 firmware

There exists, for the PW-3, KT-2, and KV deivces, a copy of the factory update_initial.bin install file.

They are **expected to** re-install the initial factory load without regard to what is currently installed.

Currently **untested** in the field.

You might very well need a serial port connection to recover your device if something goes wrong with these update_initial.bin files.

(But if you have a serial port connection already, you don't need these 'downgrade' packages to get back to your 5.6.5 firmware.
You would only be testing the packages operation for us.)

PM me for a US side of the ocean download link if willing to risk your device for us. :cool:

There may be a Europe download location also - just watch this thread for that news.

PW2 A few quick questions about jailbreak (downgrading)

I have a PW2 that is jailbroken on 5.6.5.

I want to downgrade it to something on 5.3.x and I am not sure which is the best version for my kindle. I tried to google it and I could only find release notes in random places but not in order.

I wanted to get a kindle that could change fonts (which has been very difficult, and I don't think is working), and have custom screensavers (which for some reason also does not work). Does anyone have suggestions for a version to downgrade to that is more jailbreak friendly?

How to edit margins on jailbroken KindlePW3 5.7.2

Hi!

So I have successfully jailbroken my kindle pw3. (Branch Delay is a hero) After updating to 5.7.2 the Jailbreak survived, Kual survived, had to reinstall the SS hack but that too works now. The only thing I'm missing for a perfect device is super thin margins. How can I do this? Would ixtab's JBPatch work? (http://www.mobileread.com/forums/sho...d.php?t=175512)

azw3 vs mobi vs prc/pdb on a Kindle

February 6, 2016, 10:30 am

Is there a reason to go with an azw3 file over a mobi file on a K3W? On a KT2?

I am asking as I have been using Sigil with KindleImport and KindleGen to update some of my eBooks, mostly adding proper covers to those without them, and KindleGen creates both files. The azw3 versions are larger than the mobi files, often 2-3x larger, so what does an azw3 offer me on my readers that a mobi does not?

I am including prc/pdb in my title as well as I have some of these files as well and might want to update them and was wondering what advantages the other formats would have there. I guess that might depend if the internals of the prc are TEXtREAd, zTXTGPlm or BOOKMOBI formatted.

Here is what I did for a PW3 (G090 G105 US English)

-download the jb.zip and unzip it
-move the "jb" file to the root of Kindle
-eject kindle; turn off airplane mode
-visit "kindlefere.com/jb/" on kindle's experimental browser [NOTE: watch the forum to see if this address is in favor, or another is suggested; or if there is an easy "a" method with a webserver; going to any website is done at your own risk]
-follow instructions
when the Jailbreak tells you in the notification bar to run ;fc-cache in the search bar -

Open the Kindle Search (looking glass Icon on newer touch enabled devices) and simply type in:
;fc-cache
followed by enter.

-when JB successful shows, go turn on airplane mode
-connect to computer and get jailbreak bridge file
-put "Update_jailbreak_bridge_1.14.N_install.bin" in Kindle root
-eject kindle; -make sure you're in airplane mode
-go to settings and update kindle

-connect to computer to next install KUAL
Get the KUAL-v2.6.zip archive and unpack.
If your device runs on FW 5.x, use the KUAL-KDK-2.0.azw2 file and put it in the Kindle's documents folder.
Eject kindle
Look for KUAL in the list of books, and click
click again on quit.

Next is the kual MRpackage installer
connect to computer
unpack the kual-mrinstaller-1.6.N.zip archive, and COPY the contents to the root folder of kindle.
(for me, it asked to replace the extensions folder that KUAL installed)
-eject kindle
-run KUAL
- back to home on kindle

Now time for the hacks. For the screensaver hack:
-connect to computer
copy the Update_linkss_0.24.N_install_pw2_kt2_kv_pw3.bin file into the MRPACKAGES folder on kindle
-eject
-run kual
-click helper
-click install MR packages
-watch the messages
-watch thee reboot
-put kindle to sleep
-Get kindle screensaver hack page and do a happy dance

install screensavers/covers as directed

Go forth and enjoy.
Thank you Branch Delay, NiLuJe and knc1 for the heavy lifting on the jailbreak; and thanks to Theswonker for the "JB for dummies" steps, and to all others for tips, attempts and finding solutions.

and Branch Delay, NiLuJe and knc1 - feel free to use/revise for the "a" webserver and knc1 ip address methods.

Page Margins and Line Height

Hello all,

I've been searching around the forums here and haven't found anything regarding page margins & line height updated for the Kindle Voyage (or even PW3).

I know the readers.pref method doesn't work anymore for the KV; however, is there a replacement hack?

Also looking for a line height hack to (further) shrink the spacing between lines if possible.

Thanks so much.

Modifying device options on an unregistered Kindle

February 6, 2016, 2:21 pm

For the past four hours, me and my good friend WinSCP have been digging into the Kindle filesystem, trying to figure out how on Earth settings are stored on this thing. So for the veteran developers here, two questions:
  1. Is there a central settings storage location I'm not aware of? The closest thing I've found is /var/local/java/prefs, but those files look autogenerated and possibly incomplete.
  2. Is there any way to get to the part of the Settings booklet that contains the device personalization stuff Amazon doesn't let you change without registering? The wiki has an example here that passes a parameter when launching Settings, but where did whoever wrote it get that parameter? Is there a list? Do I have to learn how to decompile JARs?
The reason I'm doing this is really because of the new home screen, which wastes more than half of its screen space trying to convince me to register my Kindle. With that in mind, my last request: if anyone here has jailbroken their Kindle, upgraded to 5.7.2, registered and disabled the home screen, could you pretty please post your /var/local/java/prefs/com.lab126.booklet.home.preferences file? Or at least tell me if and how it differs from this one:
Code:
#User preferences for Booklet Preferences
#Sat Feb 06 22:13:36 GMT+02:00 2016
FIRST_BOOT=false
HOME_FILTER_SORT_ASSOCIATION_1=title
ASR_FIRST_BOOT=false
APP_ITEMS_DELETED=true

PW2 Home button row including store has gone missing in kindle pw2

February 6, 2016, 2:30 pm

Hello Everyone.

I find myself in a bit tricky situation. Today, after i succeeded in getting a jailbreak, i installed few KUAL extensions. One of them was ie logo in search bar at here http://www.mobileread.com/forums/sho...ar#post2503720 .

I downloaded the extension and i ran it. In the KUAL launcher, it showed up as Store button changer. I clicked it and then kindle restarted, to my surprise the entire home button row went away including the option for experimental browser. The bottom row of cloud, device, all books docs periodicals and recent tough not visible are clickable by imagining their positions.

The worst part is whenever, i am done with any active games or extension , i cant find home button, so i have to restart it everytime and again and again.

On my part, with my limited knowledge i tried removing the culprit from the extension folder by deleting the folder but damage was already done.

It would be extremely kind on your part to help me deal with this situation. There is no place, i can get help with it. I tried googling for few hours but it is helpless.

I have attached the screenshot of the first screen after reboot.

Also, is this the right forum or thread to ask question? It is just so frentic for me.

Thank you for having a look at this post.

5.6.5 jailbreak easy method, with links

February 6, 2016, 4:03 pm
$

The 5.6.5 Kindle jailbreak is out!
Quite easy to use, and unlike what the post states, you do not need to host a file on a webserver.

Download the file attachments at these two links:
The Jail break archive (jb.zip) and
the Hotfix package.
Extract them on your PC.
Inside the 'jb' folder created by extracting jb.zip, there is a file called jb.
Connect your Kindle to your PC with the USB cable.
Place the jb file in the top level of the mounted directory of your Kindle. right alongside the '/documents' directory.
Now 'safely remove' or 'eject' the Kindle and remove the USB cable.

The next steps require you to work quickly.
If you're going to set down your Kindle for a minute, place it in airplane mode first.
Turn off airplane mode and connect to http://45.78.56.44/jb/ (Canada) in the Experimental Browser.
If that's down, use http://kindlefere.com/jb/ (China).
Make sure that you include the full URL, including the http:// and the trailing / .
Go to "Stage 1" and let it fail to load. Return to the URL you entered.
Go to "Stage 2" and watch the instructions on your titlebar.
It will tell you to run the ;fc-cache command in the search bar when it's ready to proceed.
Set airplane mode back on when finished.
Place the .bin file from the 'Hotfix' zip archive in the mounted directory of your Kindle.
Home -> Menu ->Settings -> Menu -> Update Device

If you are going to install any of the other add-in packages,
you must install: KUAL
and the KUAL extension: MrPI
The MrPI installer (a KUAL extension) **MUST** be used to install packages on the new firmware (both 5.6.5 and 5.7.2).

Now you are ready to add any other extensions that you find useful.
There are a few threads with compilations of links located here.

This jailbreak does survive an update to 5.7.2, but I chose to remain on the 5.6.5 firmware version.

NOTE: You can not block automatic updates using BackDoorLock.
That is known to not protect devices running 5.6.x firmware.
Choose instead one of the other alternatives.

KT2 Custom bootscreens and whatnot

I've been digging around threads like this one as well as the /opt/amazon/low_level_screens folder, and as far as I can tell, the Kindle seems to reference the /usr/share/blanket folder mentioned in the thread above more often.

Editing splash.png in /low_level_screens seems to almost work, but the image is only shown for a second and it doesn't render correctly(gets stretched beyond the boundaries of the screen)

bg_default.png in /blanket only seems to affect the "Please wait while your Kindle starts up" screen that happens right after reboot and the screen with the loading bar. However, it appears that the actual text on the reboot screens is stored somewhere else since the text still shows even after replacing the image.

Looking through some of the other images in /blanket also seems to indicate that the text for those screens are also stored elsewhere.

Does anyone with a better understanding of the Kindle filesystem know perhaps where I can find these text files or perhaps even other folders with boot screen images that I can edit?

Ookie, so I've successfully jailbroken my Kindle PW2 with Branch Delay's JB, plus NiLuJe's instructions here: http://www.mobileread.com/forums/sho...postcount=1597
now I want to downgrade, but I still get the ERROR 11, ''The update was not successful'' when I try to install an earlier software version. Tried this too: http://www.mobileread.com/forums/sho...2&postcount=12

How do I get around this?
I put the .bin firmware file to the root of the Kindle, then try to restart to update (i.e. downgrade), but it doesn't work. My Kindle is jailbroken now, so is there anything else I need to do to downgrade? Any help would be appreciated. Thanks!
