For your concideration: Getting around the locked bootloader and missing loop ko

For your concideration: Getting around the locked bootloader and missing loop ko - Droid 2 General

This is my first post here, but I figured I'd share this since doesn't appear to have been done yet.
As I'm sure most of you know the locked bootloader introduces challenges to getting your favo(u)rite flavo(u)r of linux on to the Droid 2.
I expect that you have rooted your phone and have busybox installed/working...
Normally when one wants to do this they get a linux image file and mount it as a loop device and then chroot to it's mounted folder. Because one can create a loop device but can't mount it.
My solution has been a "simple" one but may not have been tried:
Extract the contents of the image on a separate system and then push everything to /data/local/mnt.
For instance I set up a loop device on Ubuntu:
losetup /dev/loop0 /home/usernamehere/distributionnamehere.img
mount -t ext2 /dev/loop0 /home/usernamehere/somemountfoldername
Then I remove security stuff:
sudo chmod 777 /home/usernamehere/somemountfoldername
sudo adb shell
chmod 777 /data/local/mnt
exit
sudo adb push /home/usernamehere/somemountfoldername /data/local/mnt
(Wait for the push to happen stop it when you see X11/X11/X11/X11 or remove that symbolic link before pushing. If you stop it you'll have to push the other folders separately)
After it's done the bootubuntu which points to that /data/local/mnt share (or /data/local/ubuntu or /data/local/debian or whatever) should throw a few errors about mounting which is expected because we haven't fixed the fact that loop devices aren't mountable, but since we pushed the files to the 'mount' directory, the script finds it anyways and chroots to the /data/local/mnt and runs /data/local/mnt/bin/bash (or /bin/bash from the chroot point of view.)
This will get you to the root prompt.
I'm still working on getting the bash: groups: message to go away, but I think that is just that I didn't get everything copied initially.
Also I have yet to finish setting up VNC.
Anyway I hope this helps some people out.
I may do a script or more complete instructions later if requested.
Thanks,
Sky Adams

Thanks, I've been stumped by this for awhile. Your method allowed me to push the files but my script still doesn't find it. I'm going to need you to post your bootubuntu script. I have an image from androidclone.com that has vnc setup already, just need to get it to execute.

Confirmed working on rooted Droid X. Used Lakia image from androidclone dot com
1) Partitioned 16GB SD: Shrink to 11.9 GB leaving ~4GB. Then create new ext3 partition in free space
2) mount ext3 partition and create the loop to the image as skrull mentioned above.
3) then just "[email protected]# cp -r pathtoloopiface/* pathto4gbmount/"
4) takes a while but preserves the symlinks to avoid the X11/X11/X11/ issue above. (I think the reason you were having problems with the bash at the end, was an incomplete adb transfer of the /usr folder and probably no /var transfer at all. At least that was the case when I tried.)
5) push and chmod 777 this bootubuntu script to /system/bin:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
export kit=/sdcard/ubuntu
export bin=/system/bin
export mnt=/data/local/mnt
export PATH=$bin:/usr/bin:/usr/sbin:/bin:$PATH
export TERM=linux
export HOME=/root
mount -t ext3 /dev/block/mmcblk0p2 $mnt
mount -t devpts devpts $mnt/dev/pts
mount -t proc proc $mnt/proc
mount -t sysfs sysfs $mnt/sys
sysctl -w net.ipv4.ip_forward=1
echo "Setting /etc/resolv.conf to Google Open DNS 8.8.8.8 and 8.8.4.4"
echo "nameserver 8.8.8.8" > $mnt/etc/resolv.conf
echo "nameserver 8.8.4.4" >> $mnt/etc/resolv.conf
echo "Setting localhost on /etc/hosts "
echo "127.0.0.1 localhost" > $mnt/etc/hosts
echo "READY TO ROCK AND ROLL BABY! "
echo "Brought to you by NexusOneHacks.net and the open source community! "
echo " "
echo " "
echo " "
echo "Ubuntu 10.10 - Laika Edition by Androidclone.com "
echo "Website:http : / /www . androidclone . com"
echo "Email:[email protected] . com"
chroot $mnt /bin/bash
#After exit command is executed clear it all up
echo " "
echo "Shutting down Ubuntu"
umount $mnt/dev/pts
umount $mnt/proc
umount $mnt/sys
# the fuser command below allows us to kill all processes using the mount.
# otherwise umount will fail and the vnc session will still be alive.
# if it fails just run the fuser and umount again manualy.
fuser -k $mnt
umount $mnt
6) make sure there is a path to /data/local/mnt on the device and just run 'bootubuntu' from a root shell. you should get: "[email protected]/#:"
7) read the site on androidclone dot com for details on logging into the already running vnc service for a full LXDE session.
8) happy hacking.

D2G
any idea if this could free up the bootloader for the D2G allowing us to modify radio?

No, this will not circumvent the bootloader to load custom kernels. But who cares. many of the things we want, added features etc., can be loaded up in the form of kernel modules. I am not proficient enough to be able to compile my own modules yet but i'm working on a few things.

Radio
Can a kernal module be used to change the radio?

Good share, thank you very much.

ARGH!
I have probably spent 8 to 10 hours trying to get Ubuntu to boot. It seems that I cannot mount the path it wants to mount.
I can as it would seem to do this in shell it self, but still have some errors.
Do you think if I SBF my Droid X then root it - then follow the directions this would work. I am at an end now...and frustrated

[DEV] Get Ubuntu running on SGS2 (via chroot)

http://forum.xda-developers.com/showthread.php?t=1028464
Anyone tried to do that on our SGS2?
I've did this already on my Hero and on my Desire... I have no time right now, but I will try to get it running.
I'm sure it will be super fast...
Edit:
http://galaxytabhacks.com/galaxy-ta...tall-ubuntu-linux-on-galaxy-tab-10-1-tabuntu/
They already did it on the Galaxy Tab. It's time to get it running on the SGS2!

Tried it and the LXDE image is working... very fast.
I can open the file manager and everything expect the Browser... also installed firefox but couldn't run it! I get the error:
Xlib: extension “RANDR” missing on display “:1.0″.
I think this has something to do with VNC... will try to reinstall tightvnc and see if it helps.
I'm surprised that nobody is interested in this...

I'd look at it at some point, other than the fact O2 cannot organise themselves to send out my SGS2.
I think a lot of people are still waiting on phones to arrive...

pulser_g2, I think it's time to get that chroot working! I've tried again with another build with no luck. I think we need a special kernel... back when I had my desire I remember that it worked only with very few custom kernels.. because they had some parameter enabled but I can't remember which!
Under this link you can see people did the same on the Galaxy Tab 10.1:
http://galaxytabhacks.com/galaxy-ta...tall-ubuntu-linux-on-galaxy-tab-10-1-tabuntu/
On our SGS2 it would be epic... when we get it working we can just connect via VNC from our desktops to our SGS2 and use it as a PC!! Or via the viewer on the SGS2 itself... screen is big enough.
I hope someone can move this thread to the DEV forum so we can start working on it.

I started to work on running Ubuntu 11.04 on the SGSII yesterday, from scratch as I didn't find an existing way to do it. As I may need some kernel modules, I'm creating a virtualbox environment to cross-compile them.
I managed to run Ubuntu some time ago on my Xperia X10 so I already have some background on the subject so it might not take months to have it working.

I got debian running in chroot and managed to get xfce going. Not real useful at the moment but at least it works.
I just had to root the phone and followed the guide at saurik.com

Just got Ubuntu 10 running on my S2, loop device and ext4 is supported by the default kernel !

Hmm, strange... do you have root? I'm on VillainROM 1.4 with latest CF-ROOT and it doesn't work exactly because of loop devices!

I'm using an insecure kernel with default firmware.
For loop device, you need to 'losetup /dev/block/loop0 /path_to_image' and not using /dev/loop0 (returned by default by losetup but this is wrong)
and after that 'mount -t ext4 /dev/block/loop0 /my_mount_dir'
ext4 is supporting ext2/ext3 too

mount -t ext4 /dev/block/loop0 /data/local/mnt
(replace ubuntu.img and /data/local/mnt with your current image/dir)
if '/data/local/mnt' is empty then your image is broken.
Also type 'dmesg' to check why it's broken.

Using the HD2 port as basis, I got Ubuntu 11.04 running on our Galaxy SII :
Some applications don't run in the menus but most of them are ok (Firefox 5 at first!).
As Unity requires hardware acceleration, I was unable to enable it for now.
As usual VNC is needed, so it's not very smooth to use, but it seems to me that 11.04 is smoother than 10.10 on my device.

[DEV] BACKTRACK 5 on SGS2 {chroot}

Installing BackTrack5 onto the Motorola Atrix 4G

As I am not allowed to post this where it should be, this seems to be the next best place.
Hardware Needed:
* The Motorola Atrix 4G (without this you wont be going very far)
* Atleast a 4 Gb SD card
* a way of transfering data from your computer onto the SD card (The supplied USB cable or an SD adaptor)
Apps Needed:
* SuperUser (If your on this site, you most likely already have this)
* Just about any Terminal Emulator will work (I used Better Terminal Emulator Pro)
* Any VNC Viewing Client (I used androidVNC)
* A Busybox installer (I used Stericson's BusyBox installer)
Software used:
* I used the BackTrack5 version posted by msullivan, found **HERE**:
I used a slightly edited version of the bt file from the bundle
just copy and paste over the original bt file:
Code:
perm=$(id|cut -b 5)
if [ "$perm" != "0" ];then echo "This script requires root! Type: su"; exit; fi
busybox mount -o remount,rw /dev/block/mmcblk0p5 /system
export kit=/sdcard-ext/BT5
export bin=/system/bin
export mnt=/data/local/bt5
mkdir $mnt
export PATH=$bin:/usr/bin:/usr/local/bin:/usr/sbin:/bin:/usr/local/sbin:/usr/games:$PATH
export TERM=linux
export HOME=/root

echo "Shutting down BackTrack ARM"
umount $mnt/dev/pts
umount $mnt/proc
umount $mnt/sys
umount $mnt
losetup -d /dev/loop7
Installation Steps:
1. Make sure you have enough space to work with (atleast 4Gb).
2. Edit the bt file with the above coding.
3. Copy over the BT5 folder onto your SD card however you see fit, I just used a SD to USB adaptor that I got with my SD card.
4. Disconnect the USB cable if you have it connected.
5. open your Terminal emulator and type:
Code:
su <ENTER>
6. Type:
Code:
cd /sdcard-ext/BT5 <ENTER>
7. Type:
Code:
sh bt <ENTER>
8. The bt file should run, and leave you with a red command prompt.
Hit the home button.
9. Open your VNC Viewer and enter the login information.
Code:
Nickname: BackTrack5
Password: root
Address: 127.0.0.1
Port: 5901
The screen size still needs adjusting however as I believe it is set at 800×480 currently.

Sick. Just sick.
Cant wait to crack some Wifi with this. Anyone test this out and get a successful crack?

I haven't looked too far into it, however I do believe that this is almost useless as a "cracking" distro on ARM hardware. AFAIK many things don't/can't work. for instance injecting is a no go (real turn off for me, but that is what a netbook is for).

Until we get better drivers for the wifi, we don't have injection, or monitor mode. I've also found editing scripts can be a ***** because the on screen keyboard is either in the way, or the enter doesn't work as enter if using nano, running vi really hoses things up. My external bluetooth keyboard helps with this, but a bluetooth mouse while it works, is waaaaaaaaaaaaaaay (no really) too sensitive on the Atrix. Hooked up to an external monitor in webtop mode it works much better, but I've not tried running backtrack from there.

Yeah I did not even consider the ARM architecture. Very good point.
Do they make a Rosetta type app for Linux? Anyone know? That could at least help use get past the Architectural limits.
*edit*
Still not thinking straight, that app is for PPC users.

In the beginning where the script says "sdcard-ext/bt5" could I edit that to say "sdcard/bt5" in order to boot it from my internal phone memory?

Is your bt folder on your "internal" or external sd card? If it's the sdcard-ext, you'll need to edit the bt script to point to the correct location.

Hmm, tried a lot of things, ended up going to the OP of the original Backtrack on Android thread and use his original file instead, working now. But now I have a new problem, (lol) how can I change the screen resolution of the BT5 GUI to match the Atrix's screen? I've looked all over for this. I just can't find out how...

But now I have a new problem, (lol) how can I change the screen resolution of the BT5 GUI to match the Atrix's screen? I've looked all over for this. I just can't find out how...

once you start up backtrack, you need to edit /usr/bin/startvnc . Change that last line to
Code:
vncserver -geometry 940x520

Thanks and yes I did see that somewhere, I just had no clue what file to edit. So is it possible to install things like Flash on Firefox on here or is the no package installer for this? Gosh, sorry I'm asking so much...thanks for the help so far

Firefox is already installed. Not sure if flash is there since it's so insecure.

Laptop dock
After installing BT5 to Atrix 4G, can the laptop dock be used to run BT5?

I just wanted to throw a thanks out there to Exthero (since you only have 2!) for the start up script. Couldn't get it working until i used yours.
I'm having a blast with this

easiest way is on wifi:
see what your ip is
Code:
$ ifconfig
example:
eth0: 192.168.1.3
use a vnc server on your computer connect to ip address in ifconfig (port 5901 default for this chroot)

anyone know if or where the atrix wireless drivers are for this?

[HowTo] homebrew your custom Ubuntu image for Iconia A500

I'm posting this in a new thread as requested...
There is a simple way to preapare a custom Ubuntu image file compiled for ARMEL with only the packages and functionalities you need.
For this procedure you will need
- a linux machine with working ADB (I tried it on a x64 ubuntu machine)
- a rooted Iconia A500 with busybox installed
- a little knowledge about what you're doing, but just a little.
1. Install Rootstock
on your linux machine, open up the terminal and type
Code:
sudo apt-get install rootstock
If you use at least Ubuntu Karmic, it should automatically pull all the dependencies, otherwise you'll have to manually install Qemu and a newer debootstrap.
2. Create the tarball
you're ready to download the packages and prepare the tarball.
Remember: rootstock doesn't automatically include a kernel, so you'll have to manually include it in the package list
Here's the syntax for a basic run (run "man rootstock" for all the parameters):
Code:
sudo rootstock \
--fqdn [COLOR="Red"]<YOUR_CHOSEN_HOSTNAME>[/COLOR] \
--login [COLOR="Red"]<YOUR_CHOSEN_USERNAME>[/COLOR] \
--password [COLOR="Red"]<YOUR_CHOSEN_PASSWORD>[/COLOR] \
--imagesize [COLOR="Red"]<IMAGE_SIZE_IN_GB>[/COLOR]G \
--seed [COLOR="Red"]<LIST_OF_PACKAGES_SEPARATED_BY_COMMAS>[/COLOR]
Here's an example for a 2GB image with OMAP kernel and a complete Kubuntu-desktop distribution:
Code:
sudo rootstock \
--fqdn ubuntu \
--login ubuntu \
--password ubuntu \
--imagesize 2G \
--seed linux-image-omap,kubuntu-desktop
In --seed you can specify whatever package you want. You could start with just the kernel and build-essential, then add whatever you need. A good start could be like this:
Code:
--seed linux-image-omap,build-essential,lxde,tightvncserver,openssh-server
This will give you a running ubuntu with a very light, performance-oriented desktop environment (lxde) with ssh and vnc.
Remember: It's still possible to add new packages with apt-get from chroot whenever you want.
Once you have chosen the packages you want, you just have to press enter and rootstock will automatic download the packages and prepare the tarball.
You'll end up with a file named "armel-rootfs-<TIMESTAMP>.tgz"
3. Prepare the img file
This is very easy and quick:
Code:
dd if=/dev/zero of=arm_ubuntu.img bs=1MB count=0 seek=[COLOR="Red"]<SIZE_IN_MB>[/COLOR]
The seek parameter defines the size in MB of your image. make it as large as you want, it should at least be as big as the size you selected for the tarball (2G in my example).
Remember: 1 GB = 1024 MB
Now we format the image. Since the Iconia supports ext4 file system, we can use it!
Code:
mkfs.ext4 -F arm_ubuntu.img
You may want to pass other flags to define advanced options, labels and reserved blocks, but this is the least you need to make it work.
4. Decompress
Now we have to mount the img file in a loop:
Code:
sudo mount -o loop arm_ubuntu.img /mnt
and decompress the tarball into it.
Code:
sudo tar -C /mnt -zxf armel-rootfs-<TIMESTAMP>.tgz
It's done!
[OPTIONAL]
This is the right time to put custom scripts in /mnt/usr/bin like this one to start the vnc server with the correct geometry for the A500:
Code:
#!/bin/bash
rm -fr /tmp/.X1*
vncserver -geometry 1280x752
NB: the A500 screen is 1280x800, but the honeycomb statusbar (1280x48px) is always on top. To avoid panning to show the ubuntu menu bar, we just subtract those 48 pixels from the ubuntu vertical resolution.
Now we just umount it.
Code:
sudo umount /mnt
5. Load on the tablet and get it running
The script to mount and boot is derived from the one in the Backtrack 5 Thread.
Load the img file on the tablet with
Code:
adb push arm_ubuntu.img /sdcard/ubuntu/arm_ubuntu.img
It will take a loooong time and there's no progress bar, so just have faith.
Next, we prepare the boot script. The only thing you need to do is to put your username in (the one you chose in rootstock).
Code:
perm=$(id|cut -b 5)
if [ "$perm" != "0" ];then echo "This Script Needs Root! Type : su";exit;fi
mount -o remount,rw /dev/block/mmcblk0p5 /system
export kit=/sdcard/ubuntu
export bin=/system/bin
export mnt=/data/local/mnt
mkdir -p $mnt
export PATH=$bin:/usr/bin:/usr/local/bin:/usr/sbin:/bin:/usr/local/sbin:/usr/games:$PATH
export TERM=linux
export USER=[B][COLOR="Red"]<THE_USERNAME_YOU_CHOSE_BEFORE>[/COLOR][/B]
export HOME=/home/$USER
export stor=$mnt/home/$USER/storage
export sdcard=$stor/sdcard
export extsd=$stor/external_sd
export usb=$stor/USB_storage
if [ -b /dev/loop2 ]; then
echo "Loop device exists"
else
busybox mknod /dev/loop2 b 7 0
fi
mount -o loop,rw,noatime -t ext4 $kit/arm_ubuntu.img $mnt
echo "mounting storage devices in $stor..."
mkdir -p $sdcard
mkdir -p $extsd
mkdir -p $usb
busybox mount --bind /mnt/sdcard $sdcard
busybox mount --bind /mnt/external_sd $extsd
busybox mount --bind /mnt/usb_storage $usb
mount -t devpts devpts $mnt/dev/pts
mount -t proc proc $mnt/proc
mount -t sysfs sysfs $mnt/sys
busybox sysctl -w net.ipv4.ip_forward=1
echo "nameserver 8.8.8.8" > $mnt/etc/resolv.conf
echo "127.0.0.1 localhost ubuntu" > $mnt/etc/hosts
busybox chroot $mnt /bin/bash
echo "Shutting down Ubuntu ARM for Iconia A500"
umount $sdcard
umount $extsd
umount $usb
umount $mnt/dev/pts
umount $mnt/proc
umount $mnt/sys
umount $mnt
Once done, we can save the file as startubuntu and adb push it to the tab. (the same folder as the img is fine)
Done! We run it by invoking the startubuntu script from the android terminal emulator (must be in superuser mode)
I hope you found this how-to useful.

And we use this distro via our tablets ssh client?

Same happened to me. Totally not fatal. the tarball is good.
For everyone out there:
I would like your help with testing. I have a crash on start problem with firefox in all the images I tried. Does any of you have the same issue?

Hi,
i get
Code:
Loop device exists
then i did
Code:
echo "$kit/arm_ubuntu.img"
and i get
Code:
/sdcard/ubuntu/arm_ubuntu.img
but then i get
Code:
mount: cannot setup loop device: No such file or directory
any ideas?
Because of firefox.
i read a while ago a tweet about a bug in meego and ubuntu in firefox for arm.
when it is this bug then you should try firefox trunk because it is fixed.
but i cannot refind it :-(

i have the same problem. You should make loop file not in /mnt/sdcard, but in /mnt/external_sd.

That would apply only if you put the image file in the external MicroSD, if you have put it in the internal memory (as described in the tutorial) the path is /mnt/sdcard. Also, the speed of the internal memory is better.

Hi,
i found out how i can make it work
but it's strange.
i don't works when i do
Code:
sh ./startubuntu
but with this it works fine:
Code:
/system/bin/sh ./startubuntu
Is this maybe because i didn't use adb.
Someone told me that copy paste might change the permissions (what the ****! really?)
on my tablet startubuntu is not executable.
And it doesn't change anything when i do chmod 755 startubuntu
but after moving it to /system/bin chmod works fine.
After then i can always just run
Code:
su
startubuntu
and ubuntu is up and running.
(many thanks by the way :-D)

Sorry guys, will this method produce a native Ubuntu install similair to how Wubi works? Or is this like the chroot methods were we have to VNC into the distro from within Android?

It is native!!!
but you need vnc to access the xserver
On my n900 i used xephyr but i don't think this is working for android because afaik they don't use X. (n900 is so cool for linux geeks ;-D)
edit:
if you mean with 'native' that it will replace android -> no -> it is a chroot

Yeah that answered my question. Thank you
I'm not going to bother until there is a native distro running with full system resources. I guess with the current bootloader situation that day may never come :-(

It failed in creating the image for me... and it seems like a error in the package linux-image-2.6.38-8-omap

It is a chroot/vnc method, currently the only method available to run linux on this device, because of the locked bootloader... I seriously hope for a chance to dual boot in the future.

i was wondering what packages are needed in order to create an ubuntu netbook Edition? Is the A500 powerful enough for that kind of interface?

Thought you guys might be interested in this post.

Is it that vegacomb doesnt support loop devices:? Or am i missing something else? Ive checked and i have busybox installed and working correctly, but that doesnt seem to have changed anything?
Thoughts?

The vega does support loop devices, infact I have that setup running on my vega on vegacomb right now!
In order to get it working download the new scripts from the ubuntu on xoom section of the androlinux site, that worked for me fine!
Bear in mind, the version of ubuntu supplied in the image file is something like 9.10 which is very old, and the image is only 2gb which doesn't leave enough space for updating. Consider following their guide for building your own image.
Anyway, best of luck, I had to get over a few problems when installing it myself, but that may have been related to my setup, so if you have any problems I will keep an eye on this thread!
Happy Ubuntuing

Thanks for the reply, I will try the xoom scripts and see how I get on. I saw the section about building my own but wanted to try and easy 9.10 install first before building my own xubuntu 11.10. Il let you knw how I get on

Could you post your bootubuntu script up please?
I have tried lots of different loop device numbers but am getting no where!

I haven't altered my bootubuntu script at all from the default xoom one, I will post it at the bottom!
There are a few things worth checking for that may help your problems, check that the ubuntu folder on your sd card with the .img file in uses a lower case U, that caught me out the first time as my vega keyboard auto-capitalises.
Also did your ubuntu.sh script run without errors? It worked fine on mine with the old ubuntu.sh and the new bootubuntu script but you may want to try running the xoom shell script.
Hope this helps!

Right i must be missing something, i cant find the xoom section on the website so have tried your bootubuntu script in my folder but it still fails.
Can you post me a link to the xoom section of the site please so i can start over in case i missed something earlier in the process?
Thanks

right im missing something, even tried this setup here;
http://trsohmers.com/2011/03/06/how-to-run-ubuntu-on-the-motorola-xoom/
and still no luck. I have a rooted device but its almost as if the scripts are not running as root, i get permission denied messages when chmod 4777 and that shouldnt happen as root.
Im running 1.17 of busybox, not that it should matter. I am getting sick of this not working, no idea why, thinking i might have to bin vegacomb to at least work out where root might work (ie a simpler rom).

I can't remember the exact process, but I do remember getting this. I think I was missing the root login. Are you running these command as root? I think you have to use
su

Install full Linux OS on note 10.1 2014 using Linux deploy.

If we can install full Linux OS on note 10.1 2014, then it will become the truly laptop replacement.
It seems that Linux deploy is very promising, but it require a truly working root
Someone used Linux deploy to install full Linux OS on note 10.1 2012 and turned note into a full Linux laptop when needed.

Can someone savvy give it a try?

I've played around with a few installers and in the terminal by hand for a few hours. I am not able to grant permission to chroot. Even with root. I will look into this in the future.

Got Linux deploy (linuxonandroid) app working with work
Hello, Sorry meant to say Complete Linux Installer in the topic, not Linux Deploy!
I tried the Linux Deploy project with no luck. The post that was in this thread got me to the point that you need to apply a patch in the source code ShellEnv.java and then recompile. It sets it up so it prefaces all commands in the script with su when run. I was not able to recompile the code nor anyone that could give it to me. So I moved on to the Complete Linux Installer linuxonandroid app http://linuxonandroid.org/ I ran into the same problems but I was able to get around it because the script that is used to starts the Linux distribution is editable it is bootscript.sh placed in /data/data/com/zpwebsites.linuxonandroid/files this script is automatically created when you walk through the setup/install process while you are downloading an image file going through the setup process you can edit this file as it will be created at that point, where ever you see "$bbox and a xxxxx" in the script you change it to "su $bbox and xxxxxxx" so basically you have to preface all these points which there are a lot of with su. This is part of the situation. Second part is that you will need to setup the mount point for the loop directory by hand and you can see this in the script, then you will need to mount the loop directory and then create each directory inside to what is specified in the script.Then unmount the loop directory, or reboot and then you can finish the setup and launch the distribution.
You may run into errors along the way and you will need to correct them as needed. This is no easy task to setup unless you are familiar with linux and what the script is doing. Sorry I have no easy way but I was able to get it running with the Ubuntu small images to even include the display, still having so issues getting the xwindow to display correctly in the other large images which are close to a full distribution.
All my work was done with a terminal emulator, root explorer, a text editor, Complete Linux Installer(linuxonandroid from ZPWebSites), and a VNC client. Oh and using the spen and Bluetooth keyboard helps as it takes more time with just the touch interface and keyboard for what needs to be done.
It is possible to get running but you have to work at it, took me 3 hours to work through all the issues and I am familiar with Linux and its tools.
Hope this gets you in the direction you need because it was important to me to get this working for what I do. I have sent updates to the developer to hope he can automate this in the future. With Samsung's Android implementation with multiple user config it messes with the security context of scripts because each command can be run through an interactive terminal session. But the script needs to pass SU with the commands to get it to work.
I have a Samsung Galaxy Note 10.1 2014 WIFI P600 and should work with the other models too because not specific to a model. Seems this work with a Galaxy S4 as well since they are setup the same in the OS from what I have found.

This is part of the situation. Second part is that you will need to setup the mount point for the loop directory by hand and you can see this in the script, then you will need to mount the loop directory and then create each directory inside to what is specified in the script.Then unmount the loop directory, or reboot and then you can finish the setup and launch the distribution.
You may run into errors along the way and you will need to correct them as needed. This is no easy task to setup unless you are familiar with linux and what the script is doing. Sorry I have no easy way but I was able to get it running with the Ubuntu small images to even include the display, still having so issues getting the xwindow to display correctly in the other large images which are close to a full distribution.
All my work was done with a terminal emulator, root explorer, a text editor, Complete Linux Installer(linuxonandroid from ZPWebSites), and a VNC client. Oh and using the spen and Bluetooth keyboard helps as it takes more time with just the touch interface and keyboard for what needs to be done.
It is possible to get running but you have to work at it, took me 3 hours to work through all the issues and I am familiar with Linux and its tools.
Hope this gets you in the direction you need because it was important to me to get this working for what I do. I have sent updates to the developer to hope he can automate this in the future. With Samsung's Android implementation with multiple user config it messes with the security context of scripts because each command can be run through an interactive terminal session. But the script needs to pass SU with the commands to get it to work.
I have a Samsung Galaxy Note 10.1 2014 WIFI P600 and should work with the other models too because not specific to a model. Seems this work with a Galaxy S4 as well since they are setup the same in the OS from what I have found.

Yes, I will try. One thing is that the script is producing errors when you try to Exit the running distro with syntax errors on a couple of commands and I have not been able to fix them, they looks like script issues from the generated script, still need investigation and I have contacted the developer. Only way I have been able to get the system to unmount the loop device after an exit is to restart the tablet because of the script errors. Also you will need to create all the file system in the loop directory as the script is not doing it automatically.

Tried to attach file so keep getting error so pasting the script here. Just so you know this is an auto created script on setup so not sure if it is different for each install.

Yes the kernel in the thread you posted allows for Linux function in Complete Linux Installer. After the kernel is installed either use Wanam Xposed and disabling SELinux to set as always Permissive, or using "setenforce 0" in terminal(this is only for the session and once the system reboots will go back to Enforcing or if "setenforce 1")
At that point if you use getenforce at a terminal will show as Permissive and Linux will boot normally with full function.
My hat goes off to the developer of the kernel because now I have everything on the tablet I need.

FYI on my Ubuntu large installs I am running into a new SELinux issue, even with it in Permissive doing an apt-get upgrade, causes issues with an error related to invalid security context selinux, cant remember the full error. I am not seeing this with the Fedora large image. When this happens with the Ubuntu ones it breaks the KDE GUI and the Application menu ends up blank. The error occurs when install packages try to address the Ubuntu Group security, packages like colord is just an example which do a security group change. Still plowing through how to fix. Till then using Fedora which I haven't used in years

Hi,
I tried with the large Ubuntu image and get an error as well with apt-get update...not being too conversant on Linux on Android, I would like to find out if you had a fix or a resolution from the developers? Might have to stay with the Xperia Z Tablet for Linux in the meantime...

Fedora 19 via Complete Linux Installer. Have Selinux Permissive Kernel, Selinux Mode Changer, and root of course. Otherwise FW is stock MJ6.
Just a few remarks:
The Fedora image is a bit small for a full blown Linux desktop. I copied the contents to a larger 8 GB image. Had to reformat the SD card with exFAT in order to store the image there. Copying was done on a desktop computer because MTP connection just stops at 4 GB.
Changes to scripts include changing the mount command for external_sd to /storage/extSdCard in boot script. Once Linux is up and running, change /root/init.sh, find the line that starts vncserver and append -dpi 300, otherwise fonts in Linux are barely readable. Wigdets are still kind of small but at least the fonts are readable now.
If you get a connection refused in AndroidVNC, you may have to set a password on the Linux terminal for user, that is su - fedora, then vncpasswd.
Todo: find out why second start of Linux fails on loop mount busy and why shutdown complains about umount of dev.
So, my note happily runs KDE desktop, LibreOffice, and kile for LaTeX. The latter was the main reason for putting Linux on the note.

Thanks for the post. I played around with linux on my note 2 and have been waiting to get it running on my 2014. How well does it handle linux?

It runs reasonably well. I guess the limiting factor is disk I/O, or SD I/O in this case. I run KDE 4 in desktop mode with graphical desktop effects disabled and most of the KDE services like indexing disabled. It takes about 15-20 seconds from finished boot to desktop. Once the desktop is up and running, opening apps like LibreOffice is fast enough. Feels like with the first generation Atom netbooks. KDE is a resource hog, it would probably make sense to go for something that is lighter on resources but I chose KDE for girlfriend compatibility. She only knows KDE and I won't force her to learn the XFCE way or something even more obscure like Gnome3 http://forum.xda-developers.com/images/smilies/tongue.gif .
Vncserver runs at native full screen, ie 2560x1600 at 300 dpi. There was a noticable screen redraw lag when closing windows. That was easily fixed by disabling the desktop background image. I have not yet done any high load tasks. Only opened LibreOffice and kile for a quick check.
I have a cheapo foldable bluetooth keyboard. Need to get a small bluetooth mouse. Any recommendations? Or a small keyboard/touchpad combo I can take with me when traveling.

To Caferick - Fedora 19 step by step
Hi can you explain step by step how u got the Fedora 19 to wor pleasek? where i can find the bootscript?

Hum, a step by step guide would be rather longish. To answer the question: Complete Linux Installer scripts are located in /data/data/com.zpwebsites.linuxonandroid/files. There is the bootscript.sh. However, editing it is not strictly necessary. It should work as is. Alright, let's see
Preliminaries:
* need root on your device along with the usual suspects like busybox and terminal emulator (both on Google Play)
* need selinux set to permissive -> flash selinux permissive kernel (to be found in xda forums) and install something like SELinuxModeChanger (Play) set to always change SELinux mode to permissive, check by rebooting and then Configuration > General > Device Info, it should say Permissive
* useful apps include a decent file manager (I like TotalCommander), ZIP extractor (ZArchiver), text editor (Jota), these make things somewhat easier
* required app: AndroidVNC (Play)
1. Install Complete Linux Installer from Play
* start the app and open the menu by touching the < sign at the top left
* choose installation guides (or the like, my interface is not English)
* choose Fedora 19, there are four tabs, work through them in sequence, second tab presents a download button, if you have not yet installed Terminal and AndroidVNC you can use the two other buttons to do it now
* third tab asks you to unzip the downloaded image, the ZIP will probably be in /storage/emulated/0/download, move it to the root of your external SD card, unzip with Zarchiver
* there should now be a new folder fedoraXXXXX with two files in it, the fedora-*.img and an md5 file, you can safely delete the md5 file and maybe rename the image to something like fedora.img, likewise for the enclosing folder
* read the rest of tab 3 and 4
2. Start Linux
* go back to CompLinInstaller menu and push the second entry labeled Start
* a page will open and probably say Ubuntu in the drop down combo box above the Start button, change it to Fedora and type in the path to the image, like /storage/extSdCard/fedora/fedora.img
* push the Start button
* a terminal will open and a few lines will fly by. If everything goes well, you will be asked to set passwords two times, just use a trivial one like 12345678, you can change it later if you are paranoid about passwords
* you will be asked to set the resolution for VNC, type 2560x1600 which is the native resolution of the tab
* you will be asked whether you want to autostart VNC, type y
* you will be asked whether you want to start SSH server, type n
* your choice will be saved right beside the image file, in my case the file is called fedora.img.config, you can change it with any text editor
3. In the chroot terminal
* still in the terminal, the prompt should now say [email protected]
* while you are there, type su - fedora , the prompt should change to [email protected]
* type vncpasswd to set a password for VNC access, just use the same password as above, then type exit
* you are back at [email protected] If you have a keyboard (bluetooth or USB), you can edit the file init.sh with vi and append -dpi 300 to vncserver startup line. This setting will take effect at next start because vncserver. If you do not have a keyboard or do not know vi editor, you can skip this for now.
4. VNC
* start AndroidVNC, Nick: fedora, Password: 12345678, Address: localhost, Port: 5900, Color Format: 24-bit color (4bpp), Connect
* you should now see a linux desktop with tiny fonts
* hit the tabs config button to bring up AndroidVNC options, change input mode to touchpad
* you can now move the linux pointer with your finger on the display
5. Shutdown
* in VNC Linux logout just as you would log out of any other Linux desktop
* terminate VNC session by choosing Disconnect from AndroidVNC config menu
* switch to the still running terminal and type exit
* Linux now stops, wait a few seconds and close the terminal
There are still some minor problems with shutdown which I am trying to trace. A subsequent start of Linux will not work because of busy devices. So best reboot the tab and try again.
That's it for the base setup. Uh, the text is long indeed. Has it worked for you so far? Next comes customization
Corrections welcome, I typed this down from memory...

script
So we need to create script ourselves, when i've done it, i was set resolution to my tablet's resolution, then all is poor to see, that words and windows is too small to work, so it's horrible at the moment, but else works good enough. Is anyone know how to get normal UI on that big resolution? Sorry for my bad english.

Hey guys is there a walk through on how to increase the IMG size for fedora in a windowc pc ? i al ready have the SD partitioned just need to encrease the size to 10 GB

sits at boot up
My device is rooted, chroot installed, vnc installed, and busybox installed.
I install SELinux Permissive and systems sits at bootup screen. never boots to OS at any point. Just sits and the Samsung screen.
I have the Galaxy Note 10.1 SM-P600 (2014 Edition).
How long does it sit at the Samsung Boot screen before finally booting the rest of the way?
I installed using Odin 3.09.

I have running Ubuntu (xfce) on my Note 3 with Linux Deploy. VNC is not the way, it is slow. You should use framebuffer mode and you will be astonished how nice its running. Also, I modified xorg.conf for the phone to only react to stylus input and the stylus button to be right click. This setup is also working on my Note 10.1 old edition.

Can we use it without linux deploy, because it doesn't work on sm-p605? Can you point us to some guide or documentation? Thanks.
