KUAL disappeared

Hi guys, I have a PW4 successfully jailbroken with fw 5.10.1.2.
Always, ALWAY in airplane mode.
Everything was working fine until yesterday, no issue at all, all hacks and extensions working as expected (SS hack, usbnet, and I think that's all). And KUAL, of course. Booklet version I think it's the name. The one you install with MRPI.

So, yesterday I was uploading some stuff on the Kindle, did it successfully, then I chatted a while, and finally disconnected the Kindle, with "Eject device" from calibre. Ok, then... Kindle appeared as completely empty! No books, no documents, no dictionaries are shown at all.

Yet, they were visible on the device according to Calibre.

So, I deleted every book (not the dictionaries) from the device and reuploaded them with Calibre.
Operation went fine and the book are now visible again in Kindle interface.
However, I am missing the dictionaries folder (though the dictionaries are there and Kindle can use them) and most important, KUAL is not visible and therefore not runnable. ????

The Jailbreak still works, as I have the SS hack active. I used ;log mrpi to install KUAL again, which apparently worked, but again, even after reinstallation I can't see it displayed on the list. In main screen, "Document" is grayed out, as if there is no document on the Kindle.

Any idea???

K5 Need Some Advice Unbricking A Kindle Touch - Spent Weeks Trying And Dunno What To Do!

Hi there,
I have been reading posts on this forum for quite a few weeks attempting to unbrick my kindle touch and now I’m totally stumped. I’ll run down a list of what I’ve tried so far and hopefully someone can point me in the right direction.
I’m starting to think it’s beyond repair without getting inside it physically.

First, I bricked it trying to follow some advice on how to compile Debian on to it and made some mistakes which I tried to clean up but obviously it didn’t go as planned.
It was jailbroken and battery was fine. Maybe a lil shorter than brand new but it still holds a charge for quite a long time.

I saw the post about Kubrick and decided to give it a go. It took me quite a while to get it to boot but once I did I got to the screen where it needs to be set into USB downloaded mode and hey presto! Nothing.
Ive tried so many different methods of button presses to get it in USB downloader mode but no success. I tried the normal hold power till the light goes off then hold home and release power a few seconds later then finally home. I’ve tried doing that but holding power for a minute. I even tried a post that said to hold home for a few seconds then press and hold power for 20 sec then release power and finally home.

When I plug the kindle into a USB port whether computer or power socket the light always comes on orange, and no matter how long I leave it it never turns green; but I did read the light is not a reliable guide on a bricked kindle. It is possible to get a green light ONLY when it is unplugged and I hold the power for 15 seconds. It will remain green until I plug it in or hold the power again for 15 seconds.

When the battery is low I do get the needs charging screen and when it is charged, most of the time I see the tree of life screen though there are times when plugging it in and out and doing hard reset the screen goes fully black except for a tiny row of white up the top that is kinda tilted and looks like a long triangle.

I’m desperate to get this working again. I don’t even want to put Debian on it anymore, I have a bunch of books for study that would be incredibly handy on an ereader and I love the e-ink.

Oh yea, it doesn’t show us on any computer at all when it’s plugged in, even if I try putting it in USB downloader mode. Please if someone has any advice or if this is something simple I’m missing, let me know.

:help:
Thanks

(Project) Drawgress Bar — KUAL extension

January 15, 2019, 9:55 pm
$

Dear MobileRead community,
I really miss the old full-scale progress bar. I even wrote feedback to Amazon and asked them to return it. Meanwhile I am waiting for them to take actions, I gathered some thoughts.
I hope for your help! Let's finish this together :)

Goal: to write a KUAL extension that non-intrusively draws full progress bar line with chapter marks (both level 1 and level 2) on each page turn (every-page turn script example is Showtime).
By 'non-intrusive' I mean that it should be more like an overlay written as a script, rather than Java-Bytecode patch.
Hoping that methods of getting book info stay the same, this extension should be compatible with future updates.


Script outline is given below. I only half-finished drawing script, due to lack of experience in bash.
Attached an example of such a progress bar (drawn in fbink manually)

Spoiler:

Initial conditions:
－ define/determine screen size

Once book is open:
－ get book size (location/pages) (value)
－ get chapter count, level 1 and level 2 (values)
－ get chapter sizes, level 1 and level 2 (vectors)
－ get current position
－ draw progress bar with fbink

Every Page turn:
－ get current position
－ redraw

Drawing method:
1) Draw 100%-width of light-gray progress bar
Code:
fbink -t regular=/usr/java/lib/fonts/Baskerville-Regular.ttf,size=7,top=1415,bottom=0,left=350,right=0 -B GRAYC "                                                                                                    "
2) Draw in loop 1%-width parts up to read percent dark-gray progress bar (from i=0 to read_percent)
Code:
fbink -t regular=/usr/java/lib/fonts/Baskerville-Regular.ttf,size=7,top=1415,bottom=0,left=350,right=50 -B GRAY7 "  "
3) Draw in loop up to number of level 1 chapters
Code:
fbink -t regular=/usr/java/lib/fonts/Baskerville-Regular.ttf,size=7,top=1415,bottom=0,left=350,right=50 -O "|"
4) Draw in loop up to number of level 2 chapters
Code:
fbink -t regular=/usr/java/lib/fonts/Baskerville-Regular.ttf,size=7,top=1415,bottom=0,left=390,right=50 -O "·"
So for PW3 (1072x1440, 300 dpi) I have my progress bar located from 350th pixel up to 950th pixel. Each 1% refers to 6 pixels. In the first fbink command there are 101 spaces (somehow fbink doesn't draw with command of " " (1 space), but " " (2 spaces) command produces in fact 1 space), so in fact each 6 pixels is 1% of the book length.
I hope that for other resolutions it should be trivial to scale down/up.



For now I am really stuck with:
— Getting info about current opened book
— Getting pages/locations, chapters info
Where do I even start?
I remember that native booklet is in Java, but I don't know how to extract working values from there.

article: https://hackaday.com/2018/07/25/hope...for-e-readers/
It works as an alternate OS and should be unified for all readers, but this is where I think most people will use it. Currently works for kindle 5, but should be ported eventually.

Help unbricking PW1

I was pretty excited to have fixed my PW2 recently with help from posts in these forums and I really enjoyed the soldering challenge and getting into the kindle's serial console. So much so I bought a 'broken' PW1 to play with.

It is an EY21 model.

The symptoms are:
- screen looks fine, just a standard amazon screensaver on it

- no response from power button

- plug in power to wall, I get an orange light so I left it on the wall charger overnight, has made no difference.

- plug into PC via USB, I got "installing NS Blank Codex" one time, subsequent USB connections don't show this. I plugged it into a different PC and also got a one time message of "installing NS Blank Codex".

- Connected up a serial port, plug into wall charger (orange light), press power button and I get the following in the serial console:

Any ideas what I could do next? I'm happy to read up and experiment, that's why I bought it so I can learn :) just not sure what my step should be....?

P.S. I mostly work on windows but i do have a raspberry pi as well if I need to do stuff under linux.

A word of thanks to all the devs

Through my own stupidity, I had to reset my voyage and lost my jailbreak. I'm now stuck with stock firmware and remembering how much less useable it is for me without the jailbreak and customizations. (My vision is 20/200 at best and I spend a lot time tweaking the UI to what I need to be, which isn't possible without the jailbreak.) As usual, you don't fully appreciate how good a thing is till you lose it :/

But yeah, I want to say thanks to all the devs who've done great work over the years to let us tweak our Kindles, as well as all the folks keeping the lights on here in the developer's corner. NiLuJe, ixtab, coplate, twobob, knc1, geekmaster, and anybody else I forgot to mention. Thank you all!!

KUAL "listing bump" proof of concept

January 19, 2019, 9:31 am
$

The list view listing for the KUAL booklet drifts down the screen and eventually off the first page as other books are opened even if KUAL has been used in the meantime. That is, the access time for the booklet KUAL does not get updated, unlike the kindlet KUAL.

The good news is that updating p_lastAccess for the KUAL record in cc.db raises KUAL to the second entry of the list view listing with the Recent filter after another book is opened and closed. The bad news is that the sqlite3 on board the kindle can not update cc.db (See post #1862 in https://www.mobileread.com/forums/sh...03326&page=125 )

Proof that there is hope:
Code:
mkdir local
sshfs root@oasis:/var/local local
NOW=`ssh root@oasis date '+%s'`
sqlite3.26 local/cc.db "SELECT icu_load_collation('en_US.utf8', 'icu');  update Entries set p_lastAccess = $NOW where p_titles_0_nominal = 'KUAL';"
fusermount -u local
Open a book on the kindle, then close it. KUAL will be the second entry in list view.

So, with a kindle sqlite3 binary that speaks icu, it would be straightforward to make a KUAL extention that bumps KUAL's listing.

Manually copy full filesystem to Kindle 3?

So you know how you've all read a thousand posts that start with "I used to have a Kindle 3 and......sat in a drawer for a long time.....tried to start it up again.....only shows the empty battery screen.....tried soft reset......had to do a hard reset.....etc..."?

Just substitute one of those. For the first part of this post. You've heard it all before.

Now for the (somewhat) novel stuff--I've done, so far as I can tell, about ten thousand different troubleshooting and recovery things to try to get this darn thing working again. Some of my greatest hits:
  • called customer support -- no dice
  • replaced the battery and charged it -- nope
  • ALL the resets -- did nothing
  • shorted across the reset terminals on the PCB for the device -- bupkes
  • put .bin files GALORE in the root directory in recovery mode and restarted -- NO

It will go to recovery mode. When I exit recovery mode it starts to restart, I get the progress bar, and then before it gets halfway full it goes back to the empty battery screen.

I've been trying to figure out how to jailbreak the thing to see if I can get SOME use out of it (I don't have the necessary TTL cable for any of those methods), and the non-serial options involve modifying the existing filesystem. But here's the thing: it doesn't seem to have a filesystem. When I open the device to view files when it's connected to my computer in recovery mode, the drive is empty.

I've checked for hidden files and even tried looking at the partitions. There's one visible partition that is 3GB, and that's it. And it's empty. (Well there's your problem, you might be saying...)

What I'm trying to figure out is if I can get ahold of a disk image or something of ALL of the files that would normally be on that primary partition and copy it over manually. Does that exist? Is it even possible? Would it even work?

Or did I miss something else?

Thank you for any insight you may have.

I finally got around to putting koreader on my Oasis 2.

On my Voyage, all the filemanager start choices seemed about the same (as near as I can recall).

On my KOA2, the top entry resulted in the start message at the bottom of the screen and the device remained unresponsive for quite some time and I had to reboot via power button.

Which filemanager start works with the KOA2?

Yes so updated to 5.10.2 and then applied hot fix and KUAL booklet. All good and KUAL works.

But now my Kindle screen won't turn off. I restart after holding for 30 seconds and try to turn screen off and still won't work. I choose 'screen off' in Power menu and nothing.

Any ideas?

KT3 Problem with my kindle 8th generation.

Hi friends,
I have kindle 2016 8th generation model no is sy69jl. Apparently it has a problem with the battery, because it does not charge when it is on, the battery runs out quickly and the empty battery icon appears with the exclamation mark. I discovered that by connecting it to the wall charger for 4 hours and then leaving it for 2 hours without charging, or touching, it finally turns on. But the battery lasts only a few hours in reading mode with the wifi and bluetooth turned off. Once it turns off, I get the exclamation mark and it does not turn on, not even pressing the power button for 40 seconds. I also discovered that if I disarm it and disconnect the battery and reconnect it, it starts again, and it works a few more hours. But I do not want to be disarming it and disconnecting the battery every time it shuts down. The other way I discovered is putting it in the refrigerator for about 40 minutes to cool, take it out with a towel and connect it to the wall and then turn it on.
I do not know what's going on, because it worked well, I do not know if it's the battery or the motherboard. On YouTube I saw that some tablets (not kindle) do not recognize the load properly and make a bridge between the charging pin and the battery, because the positive does not work as it should. Do you have any suggestions or ideas? or I have to resign myself to the idea that my kind died.

Postscript: the kindle is no longer guaranteed, I contacted and was offered 40% off in the purchase of a kindle. But they do not have shipment to Argentina :(

Thank you all for your time. Sorry the long post and a bad English.

K4 K4NT Properly bricked after screen replacement, help please!

Hello,

I've just finished replacing the screen on my K4NT (horrible job, wouldn't recommend to anybody!). Since getting it back together I have a "Your kindle needs repair" message.

I've written KuBrick to a CDR and it gets through the first screen, but fails at the second, I think it's when trying to get into fastboot (I'll try and get a photo to show what I mean).

Is it totally broken? I can replace it but I hate to throw things away when they could be fixed.
