Sweet, I think it will be a lot easier with a thread just for Kindle 4 Non Touch.

So what is the status on a legit Jailbreak for the K4.? I have setup SSH access via WIFI but I'm having problems getting sftp-server working.
Im using this version: LINK
We should work on getting the simpleusbnet for the Touch JB working on K4 as well.
Let me know if anyone has got this to work.

Hello,

I primarily use Windows. I have written instructions to root the Kindle4 via usb networking and how to add custom screen savers. The information in the files is primarily from all the previous posts in the Kindle Touch thread. I only re-wrote the information from a Windows user perspective. Thanks must go to all of those who helped in the rooting of the Kindle.

You still need to have a basic understanding of Unix file systems and
commands.

I have attached two text files:

(1) Kindle Root Access via USB Networking.rtf
(2) Kindle Custom Screensavers via USB Networking.rtf

Good tutorial,
Imma do what I can to get SCP working this week. I just got back from University and have tons of time on my hands.
Let me know in anyone has any Insights.

Hi danar,

you "re-wrote the information from a Windows user perspective" - so do you have an instruction for the same purpose for Kindle 4 (NO Touch) on Linux systems?

[ I'm afraid I am not familiar with Windows :/ ]

Getting shell access from linux would go something like:
* Connect your kindle as a usb mass storage device
* touch ENABLE_DIAGS in the device's root
* reboot the kindle through the setting menu's menu
* you're now in diags mode
* connect your kindle and computer using the usb cable (nothing should happen)
* in the menu, enable usb networking (Misc individual diagnostics > Utilities > Enable USBnet)
* the kindle should now register as a usb ethernet device (relevant messages should appear in /var/log/syslog )
* on your computer configure the ip address on that device: ip addr add 192.168.15.241/24 dev usb0
* use ssh to connect to the kindle: ssh root@192.168.15.244
* the password should be "mario". If mario doesn't work, use the python script mentionned in the previous post to generate the password from your serial number.

This is just a long version of https://www.mobileread.com/forums/sho...03#post1868403 and subsequent posts.

Btw, note that "FW" in diagnostics mode refers to the "Five Way" controller, aka the direction/ok pad.

Wow! That was fast Thanks a lot for your help!

You're welcome.

Note that extra steps are needed to make it possible to connect to the kindle in "normal" mode. Those mainly involve copying the /usr/local directory from the diagnostics image (/dev/mmcblk0p2) to the normal image (/dev/mmcblk0p1) and optionally adding a rule in /etc/sysconfig/iptables to allow incoming tcp connections on port 22 on the wireless interface if you want to ssh without having to enable usb networking.

It's also worth mentioning that the /var/local (/dev/mmcblk0p3) directory is shared between those two modes.

I've had ssh via wifi up and running with my K4 non-touch SO for a few days. I was able to change the root password with passwd to something easy to remember. scp works just fine now that I've figured out the syntax, but I'd really like to get sshfs working so I can just mount it on my Desktop and move files with Nautilus. The problem is it won't accept a password. I think it needs public/private key negotiation. I've generated the keys but don't know where to put the public key on the kindle.

[dionoea]

They're usually put in ~/.ssh/authorized_keys server side. Google "ssh authorized_keys" for more information. I'm not sure that it'll work on the kindle as I haven't tried it yet but I don't see why it shouldn't (unless the ssh binary was compiled without key support)

could set kindle 4 unlimited Partial Refresh like nook2?

I believe that this topic was intended for the kindle 4 non touch (aka K4 / K4-NT) only. You can get info on a touch jailbreak on: https://www.mobileread.com/forums/sho...d.php?t=160454 (published by yifanlu 10 days ago).
