That implies of course that I was able to connect via SSH in DIAG-Mode/USBnet (using linux).
Root-password was 'mario', though I'm on 4.0.1 and the python-script gave me 'fiona1def' as password.
Now, when I try to connect via WIFI (in normal-mode) 'mario' doesn't work. Neither does 'fiona1def'. I can, however, connect with username 'framework' and password 'mario', but without root-privileges...

Is there any configurationfile that differentiates between SSH via WIFI and USBnet? Or did I overlook anything?

I know, you alredy solved it , but you can also ssh over wifi with root password like that:
first login as framework:mario
then write "su root"
type fionaXXXX password
now you are logged in as root.
note: when logging out, you must type "exit" twice: first for root, then for framework

Hi folks, I'm trying to do something a little different. I don't really mind the screensavers, but I'm frustrated at how quickly the screensaver activates. Ideally, I'd like to have the device time-out with my current page as the screensaver, but I'd settle for just extending the time before the screensaver kicks in? Anybody know how to do this on the Kindle 4 NT?

I thought I'd just edit /etc/powerd.conf, but no such luck. It isn't there on the Kindle 4 NT!

Fiddled a bit and found it (at least to increase the time until the screensaver comes up)

ssh as root, then

mntroot rw

afterwards

vi /etc/kdb.src/yoshi/system/daemon/powerd/t1_timeout

the last line indicates the number in seconds before the screensaver comes up
(it's set at 600 - so 10 min)
just change that to a number you prefer, following

/etc/init.d/powerd restart

and that should do it

Hey, thanks for finding this. I was trying to figure it out myself!

[Phre]

I like to use the current book cover as my screensaver.
Calibre has a plugin for copying the cover to the jailbroken Kindle 3

On the Kindle 4 NT using the screensaver tutorial.
If I modify the command line below will that change my default screensaver directory to the subdirectory linkss/screensavers (after creating those directories manually) ?


Original = ln -sfn /mnt/us/screensaver /mnt/base-mmc/opt/amazon/screen_saver/600x800

New = ln -sfn /mnt/us/linkss/screensavers /mnt/base-mmc/opt/amazon/screen_saver/600x800

If this won't work is there another way to do it?

Thanks
Phre

Many thanks for the ideas. Unfortunately, this didn't work for me as there is no /etc/kdb.src/yoshi/system/daemon/powerd directory on my K4 :-(

I did find something that looked interesting though. There is a /sys/module/keyboard/parameters/brl_timeout file which is currently set to 300 seconds. However, /sys is mounted as sysfs. Anybody knows where this timeout might live in the device tree?

Hmm, that's odd, because I got a K4, too..
Just checked on another device (abused my girlfriend's one ) and the directory is there as well.

Maybe a typo?

Mine is a Kindle 4, non-touch, special offers version. There's definitely no /etc/kdb.src/yoshi/system/daemon/powerd directory.

[xorphex]

Well, then I guess it's because of the special offers version...
I'm from Germany and we don't even have this version (but the normal version costs around 130 dollar...)

Did you try

find / -name t1_timeout

in the ssh shell?

I have the same Kindle and the directory DOES exist in mine. Maybe the difference is the software version? I upgraded to 4.0.1.

I just upgraded from 4.0 to 4.0.1 and the /etc/kdb.src/yoshi/system/daemon directory has only otaup and usbnetd sub-directories; no powerd sub-directory. Somehow my Kindle is still timing-out to screensaver after 10 minutes, but I don't know how. (I was hacking in the daemon directory prior to upgrading though, so maybe I did something bad?!?) Can anybody else with a US Kindle 4, non-touch, special offers 4.0 or 4.0.1 let me know if you have the t1_timeout file and whether changing it makes any difference? (BTW, I checked with "find" and I didn't/don't have a t1_timeout file anywhere in my Kindle's filesystem.)

Hi, absolute noob here but.. what exactly does that entail? Everything in this thread is incredibly fucking confusing and I have no idea what that implys.

Jailbreak means root access or access to diagnostics mode, right? Why would I need that if this file you made just works through updating?

Thanks if you feel like helping a lowly nub..

Edit: Nvm.. this https://www.mobileread.com/forums/sho...&postcount=240 post explained. Your update is self-signed so otherwise the kindle won't accept it.

Then my next question that I probably already know would be whether theres a safe way to jailbreak thats not full of developer jargon.. bah.

Double Awesome edit:
Found a very simplified explanation on hacking it
I've inserted your hack into the Kindle NT hacking wiki page here:https://wiki.mobileread.com/wiki/Kindle4NTHacking
It would be super cool if you could explain more about how it works, for example, whether inserted images require a special name, or the danger of bricking.

@Swashy, it's screensaver hack by NiLuJe with some small fixes to work on K4NT. Check this topic

Also here's font hack :
http://dl.dropbox.com/u/16679763/upd..._4.9.N_k4w.zip

And simple jailbreak using ixtab method :
http://dl.dropbox.com/u/16679763/kin...lbreak-1.0.zip

To JB :
- Copy RUNME.sh and data.tar.gz to your Kindle
- Reboot from settings menu
- enjoy

Just found this from another forum.
On the K4 (non-touch):
1) Tap the keyboard button.
2) Type ;debugOn and then finish with a return. (Nothing appears to happen.)
3) Type ~disableScreensaver

Now the screensaver will never kick in (not even when you press the power button, so you'll need to power-off by holding for 7 seconds). This is easy, but I still wish there were a way to adjust the timeout. I've not yet found that on my version of the K4.

P.S. Kudos to AmeliaA who posted this tip for the K3 on another forum. I can confirm it also works for the K4.
