Native [WIP]replacement firmware for Kindle/Kobo?


JavaScript debugging in mobile browser and WAF

Hi all!

Does anyone have any pointers for the best way to get javascript console output in the Kindle experimental browser? I'm struggling to identify which apis are present in that version of WebKit (things like promises and fetch didn't exist yet).

I'd love to be able to catch those errors in a more elegant way than document.write on window.onerror. :)

Any help would be much appreciated!

PW4 MRinstaller error on PW4 5.10.0.2

Hi everyone. I am a new kindle owner and this is my first post here. Great forum, thanks to everyone for your work!

Been searching for a few hours, and hitting a specific roadblock setting up KUAL that I haven't seen anyone else hitting. So far I've:

Successfully jailbroken:
https://www.mobileread.com/forums/sh...d.php?t=312489

Latest hotfix successfully installed - still on 5.10.0.2 though (the Kindle isn't detecting OTA update to latest 5.10.3):
https://www.mobileread.com/forums/sh...postcount=1597

However, whatever MRinstaller I try, I get an "MRPI is not installed" error message in the top left corner of the PW when trying to run the KUAL package with ;log mrpi.. nothing else happens. It is not generating a log. Kindle is still functional.

I've tried the original MRinstaller from here:
https://www.mobileread.com/forums/sh...d.php?t=251143

And the latest version from here:
http://cloud.ak-team.com/

In combination with both the original and latest KUAL launchers, and the coplate version.. I've been trying to launch them all from the mrpackages folder with ;log mrpi but getting the error message

@dr.network appears to be the only other person on the internet to have this error, and seems to have resolved it, but I can't follow how. I've tried to use any updated MRinstaller files I could find with no joy

**Any ideas?** I would really like to install a custom screensaver on my new kindle, and now its getting personal.

Don't know how to code, but could be walked through whatever is needed.

Thank you again!!

PW2 Why don't downgrades work after 5.8.7.x?

Do we know what Amazon patched out of the firmware to prevent downgrading after 5.8.7? I've been trying to figure it out by comparing different OTA bins using NiLuJe's KindleTool but I haven't found anything. I'll probably end up doing the serial port method (I'm on PW2 firmware 5.10.3) but it would be nice to figure out a software jailbreak again.

PW4 I made a basic remote desktop

I made a very basic remote desktop for my PW4. You need a webserver and python.

There are 3 cgi scripts, a html file, and a python script:
  1. screen.cgi takes a screenshot and returns the path
  2. power.cgi presses the power button
  3. touch.cgi sends coordinates to sendtouch.py
  4. sendtouch.py writes events to the touchscreen
  5. index.html shows the screenshot you can click on

The only problem is that fake touches don't prevent the screensaver. I could use some advice on how to fix that :).

Kindle deactivation by Amazon. Can i still use it?

$
0

I just called the support from amazon to talk about some horizontal lines that appeared on the top of the screen of my kindle paperwhite 2nd gen; and since there's no technical support for these devices in my country (Brazil), they offered me a gift card so i can buy a new kindle, and then they would cancel the registration of my kindle, and i would not be able to register this device again. There's any way i could bypass this? Jailbreak or something else? It's still a perfectly cappable device and it would be a shame if it turns into a paper weight.

K5 Backing Kindle Touch up before upgrading firmware

$

Because of lack of suggestions to fix Kindle Touch slowdown, I decided to upgrade firmware to the latest official Amazon version. First I'll upgrade from 5.1.2 to 5.3.2.1. If this doesn't help, I'll upgrade further to 5.3.7.3.

I'd like to have an option to downgrade back to 5.1.2 if the upgrade causes more issues than it solves. How can I back up my Kindle? I have read A: The easy way section here: https://wiki.mobileread.com/wiki/Kin...Hacking#Backup. The SSH-enabled diags partition instructions README.txt file download link is broken. The even simpler way using Kubrick seems to refer to flashing firmware without prior backing up. So is Kubrick an easy and reliable way to revert to an earlier firmware version, which eliminates the need of system backup? Or is it still safer and recommended to make a system backup beforehand? If yes, does anyone have the now-undownloadable README.txt file with instructions? Or is there a newer, easier way not mentioned in the Wiki? For example this backup script was tested on KT firmware 5.3.7.3, so I'm not sure it will work on my old firmware version; plus the instructions seem to assume already working USB networking, which I don't have yet.

My computer system is GNU/Linux (in case this makes a difference).

Kindle PW1, 3G, 5.4.4.2, Jailbreak and update?

$

Hi everyone,

I've got a Kindle PW1 with 3G running 5.4.4.2. I hadn't used it in a long time, so I guess with 5.4.4.2 the 3G service doesn't work anymore.

I recently conducted the 1.14.N jailbreak to use KOReader, and am now wondering how/if I can get 3G working again.

Do I need to update firmware? If so, how do I do that and keep the JB?

Thanks!

Ayuda!!

NOW the issue.
At the moment i am switching from portrait mode to landscape manually on the kindle.
I mounted the Kindle in a picture frame, so the keypad is not accessible.
Sometimes the Kindle has an issue and come up with the screensafer and portrait mode.

IS IT POSSIBLE TO SWITCH FROM potrait mode TO landscape mode WITH A SSH COMMAND?

Does using Calibre Collections to install new fonts on legacy kindles?

$

I just got a Kindle 4 NT (used to have one and traded it in, regretted it, so got a cheap one on Woot).

I'm really enjoying reading on it, but was trying to add the Bookerly font to it, and, when that didn't work, the Bitter font.

I followed the procedures as found here on MobileRead and have had a frustrating time.

The margins have been altered successfully using Calibre Collections, as has the line spacing. But, each time, when I go to the alt typeface on the kindle, it is just the same!

I've tried many times - always ensuring I am on the HOME SCREEN before I add the fonts and select the correct font name from the dropdown menu in Calibre Collections.

I've also tried resetting my kindle to factory settings, same problem though.

Is it just the case that this no longer works for 4.1.3 and I need to do the full hack to get my fonts on? (I don't really want to do this, as when I hacked my DX the battery life went from around a month to a maximum of two days, and one of the reasons I backtracked to this K4 was the awe-inspiring battery life).

Thanks anyone for any suggestions.

I should say I am on a Mac - often when I add a new font to the fonts folder I created, it creates what look like 'shadow files' which have the same name but with _ in front, and they are much smaller than the original files.

Or is it just that the book I'm reading doesn't support alt fonts? Book purchased through amazon, so I don't think it's that.

Hi,

So I'm currently doing some tinkering on my kindle voyage but I'd like to back up my partitions and diags to be safe.
I tried searching for a guide but can't find one that explains it well. I've already connected my kindle with a TTL device and connected it to my pc (having a bit issues with the login though as root and the generated password are not working).

Anyone can tell me what to do to get a full backup of it? I'm using putty atm but I do also have a linux pc at the ready in case I need it.

My device is an kindle voyage V5.10.1.1 not jailbroken

HTML5/CSS3 Support for Kindle's Experimental Browser

$

Hi, I'm trying to design a static web page to be viewed primarily in the experimental browser on my Kindle Paperwhite (2nd Gen.). My firmware is reasonably up-to-date, the last update was not more than a few months ago. The page design is very straightforward, I'm just looking to display a book's cover with the title and author's name written alongside (image attached here). My approach is to use flexboxes, very straightforward with boxes nested and margins and paddings set to some trial-and-error values. However, my webpage renders fine on the computer and mobile (tested for both Firefox and Chrome), but the rendering goes bonkers on the Kindle Paperwhite's experimental browser. I'm guessing that this arises out of the Experimental Browser's faulty/incomplete implementation of HTML5/CSS3, but I'm unable to find any documentation about the same, so could someone help me out here? I'm kinda out of my depth, as I'm only an amateur programmer with zero experience in web development in general.
