I'd like to know if there is a schematic to make a serial cable for the DXG.

I have a usb to rs232 (F5U103ea ACER),

An nokia 3510 rs232 serial cable with 4 wires
The voltage measured is around Vout=0.1v dc

An nokia 9210 rs232 serial cable with 6 wires
not tested yet.

How can i use this to make a fully working serial cable?

Hi guys. Anyone can help me? I've been trying to fix the timeout screen on my kindle paperwhite 7th.

I'd like to disable this function and makes the screen be always turned on! I've also tried the command ~ds in the search bar, but it doesn't work at all.

There's another way?

Thanks!!!!!!!!!!

PW2 Need some advice for resurrecting PW2 from a failed software update

$

After searching through many threads on this forum and google I have come to a point where I need some expert advice on a proper course of action. My stock/unrooted kindle ran into trouble during an update, where it stuck at around 15% on the 'software update' screen. It will reset when I hold the power button for 30 seconds but it immediately boots into software update and the status bar climbs back to 15%, then stops.

So far I have tried charging it for days, contacting Amazon CS, and attempting to access the kindle in both Windows and Linux, but nothing has helped. The kindle isn't recognized in either OS and the Software Update loop continues.

I haven't found a similar occurrence of this issue through my searches so I'm not quite sure on the course of action. I am thinking that my issue is more of a soft-brick and am hoping that there is simply a file that needs deleting or modifying.

In preparation I have ordered a MicroFTX compact MicroUSB breakout available from http://jim.sh/ftx, which will arrive tomorrow. If it's actually bricked I plan on following THIS tutorial on gist.github.com

Thanks for taking the time to read this, I really appreciate any/all ideas or directions.

hello!

Thanks for having such detailed guides on jailbreaking kindle. I have successfully jailbroken mine and installed KUAL. I am able to open the launcher but I see that it can't find any extensions despite the fact that the directory structure looks like this:

What am I doing wrong here?

Have this paperwhite. Freeze after upgrade like at the first picture. Try to hold power button. But no help. Steel the same. Doesn't turn on. Try this instruction (http://www.xodustech.com/guides/kind...te-demo-unlock) but it does't help. There is no any messages at the Putty.

KPV vs liberator, differences for PDF use?

$
0
0
hello all,

I am a Kindle DX user and I have been using both on and off but I really cannot see that many differences. I mostly confused at this point and I am wondering if one is more stable than the other and which one uses less power.

It has been a while now that I have used both, I have abandoned a bit my Kindle because I had problems with screen freeze and problems with the Kindle coming back from sleep and I do not remember if this was with Liberator or KPV. So before I plunge back in I am wondering if one is more stable than the other for PDFs and which one uses less power? Because the status of my battery is really bad and it seems that these two use a lot more better rate than the stock PDF reader.

Any insight would be helpful. Thank you

PW3 KindleLazy - remote control page turns + brightness

$
0

Hi, here is KindleLazy 0.5 :)

Video:
https://www.youtube.com/watch?v=Ti_KD58UWuc

You can turn pages and alter brightness via a device like a keyboard.
I use a wireless 'presenter', it sends keys like page up, page down etc.
I specifically use this product: https://www.amazon.com/dp/B00SYK18T0

KindleLazy is configurable, you can set what keys do what action.

Thanks to lucida and knc1 for the help.
lucida for the usbotgmouse extension which I based my extension on, advice on using Amazon's toolchain etc...
knc1 for all the general help to me and all over the years!
plus every other helpful member, thank you.

KindleLazy 0.5 readme:
Spoiler:

KindleLazy 0.5 - cearp

Only tested on PW3, nothing else!

At the moment this only reads from event2 and event3 - this is what my device reads as.
This should be improved later.

There is no hotplugging, have the device inserted before starting. If the device is removed, this app may quit.

The page turn direction can be reversed, so that your 'forward' button can still advance you to the next page.
For example, with books that are 'right to left', where the next page is on the left, you would reverse the direction.

The program will not work without a config file named 'config.json' in the same directory.
NOT menu.json and NOT config.xml, these are files for KUAL.

Here is a sample (and the default) config file:

{
"key_brightness_down" : [ 115 ],
"key_brightness_up" : [ 114 ],
"key_next_page" : [ 104, 103, 106 ],
"key_prev_page" : [ 109, 108, 105 ],
"reverse_direction" : false
}

Errors in the config file are not handled, it will probably crash.
Beware of commas and other punctuation.

Enter the keycodes for the keys you want to trigger the actions.

For the config above, the key codes represent:

104 = KEY_PAGEUP
109 = KEY_PAGEDOWN

103 = KEY_UP
108 = KEY_DOWN

105 = KEY_LEFT
106 = KEY_RIGHT

114 = VOLUME_DOWN
115 = VOLUME_UP


I can see some keycodes here, I am not sure if some devices produce different ones.
https://android.googlesource.com/pla...rds/Generic.kl


I want to improve this and add hotplugging (inserting/removing the usb device(s) any time when the program is running)

I also want to print a message to the screen (like usbnet does) that shows when the program starts, the current page direction, show a message when the program quits, etc...

I assume this will work on KV, OA... I'm not sure about PW2.
As for future proofing, the screen size is not hard coded so it should work with any resolution.

Any advice on how to do these things, or just advice on my programming is welcome!
Pull requests on github are welcome :)

Need help after a jailbreak attempt.

I have a Kindle PW 2, 6th gen, and I can't update it anymore.

I've downgraded it to the version 5.4.3.2, and I jailbroke it, but it won't let me update it to the latest version. The update file is in the device's root directory, but the update button is blanked out. I followed this tutorial step by step, but I'm now facing this problem.

I've tried resetting it a few times, but I just can't update my kindle anymore.

I'd be glad if someone could help me out of this.
Thank you in advance.

K5 Seafile Client

Hi There,

I've made a very simple Seafile https://www.seafile.com/en/home/ client.

Currently it lives here:
https://github.com/trap000d/seafile-kindle-client

Known Issues/Bugs
- Only one way synchronization
- Client doesn't erase sub-directory (and it's contents) if it's not exist on the server
- Non-latin characters are not shown through eips
- Just rudimentary checks of internet/WiFi availability/file operations
- SSL certificate verification ignored (verify=False) just to make it work with self-signed SSL certs

So I've got some questions to developers:
1. Is it possible to put text to Kindle screen from bash/python script other then with eips (to use Unicode characters)?
2. Any suggestions in regarding to self-signed SSL certs, or just left it as is (verify=False)?

K4 Kindle 4: Duokan or Jailbreak?

$

Hi People. I'm very confused so I would be really grateful if you could help me.

A good friend of mine gave me as a present an old Kindle 4 and I want to improve its functions, but I'm very confused of what is better: to hack it using jailbreak or to install duokan. I know that the former option is always the better, but being an old model I'm not that sure. So:

(a) Jailbreak or Duokan?

(b) If Jailbreak, what modifications do you recommend?

(c) If Duokan, which version?

(d) My version is 4.1.3, should I downgrade it? How?

Last but not least, my language is Spanish. I don't know if that changes thing.

Thank you a lot :)

KT3 Wi-Fi issue

$
0
0
Thanks to an old tutorial by knc1, I was able to set up wi-fi access from PC to PW1, PW3 and KT3. Using shared keys, no need for password too.

However, I face a peculiar issue with KT3. I'm unable to access KT3 from my PC(netbook running Ubuntu 14.04). Any pings to KT3's I.P don't succeed.

As a workaround, I open kterm on KT3 and from there, ping the PC's I.P - which works. After this, I'm able to ping/connect to KT3 from PC.

This reminds me of similar things I used to do on old PCs at my workplace.

I suppose there must a simple (or profound ;)) reason for this behaviour?
