One of the fun things you can do on your Android device, is to play around with different ways of getting a real distro (Debian, Ubuntu etc.) working along side the Android system. There are several (A lot) of tutorials in here on how to do this, so this part will not be covered here. This thread only contains some scripts that will help make it easier working with the chroot.
Most of the scripts that comes with the endless pool of chroot tutorials, is only made to mount and unmount the distro image in the most simple way. But nothing that helps walking in and out of the chroot without mount/unmount, and nothing that takes different services, busy devices etc. into consideration.
The debian.sh script in this thread has many tasks. It will on execution check to see if the image is mounted or not. If the image is mounted, it will just enter the chroot. If not, it will mount the image and then enter the chroot. On exit it will provide you with the option of exiting the chroot or exit and unmount.
Also it provides 4 custom scripts that is placed and executed inside the chroot. One for mount, unmount, enter chroot, leave chroot. This makes it possible to control chroot services much easier.
The script debian.sh is executed using the command "debian". You can also unmount the chroot from within the android shell by executing "debian unmount" instead of entering the chroot and then exit choosing to unmount.
The unmount process has several and different unmount attempts in case of busy devices, running services etc. which will make sure that the chroot is successfully unmounted.

By default debian.sh will look for /mnt/sdcard/debian.img and mount it at /data/debian
The script has build-in first-time-install functionality that will create missing directories etc. Just change the variable "FILESYSTEM" in debian.sh to the correct path and filename of your distro image, and it will handle the rest.
Chroot Init Scripts
Inside your chroot, you can create the directory /etc/init.chroot and create the fallowing files.
rc_mount.sh - Executed after mount
rc_unmount.sh - Executed before unmount
rc_enter.sh - Executed when entering chroot
rc_leave.sh - Executed when leaving chroot
Here are an example of a mount and unmount script used to control tightvncserver.
File: (chroot) /etc/init.chroot/rc_mount.sh
Code:
#!/bin/sh
# Make sure that the vncserver is completly stopped before starting.
if [ ! -f /tmp/.X11-unix/X1 ] && [ ! -f /tmp/.X1-lock ]; then
# Start vncserver
vncserver -geometry 800x480 :1
else
# This is in case something went wrong the last time
# it was shut down. Perhaps an uncomplete unmount.
vncserver -kill :1 2> /dev/zero
unset /tmp/.X11-unix/X1 2> /dev/zero 2> /dev/zero
unset /tmp/.X1-lock 2> /dev/zero 2> /dev/zero
vncserver -geometry 800x480 :1
fi
File: (chroot) /etc/init.chroot/rc_unmount.sh
Code:
#!/bin/sh
# Only stop this if it is started
if [ -f /tmp/.X11-unix/X1 ] || [ -f /tmp/.X1-lock ]; then
vncserver -kill :1
# Make sure that these are removed
unset /tmp/.X11-unix/X1 2> /dev/zero
unset /tmp/.X1-lock 2> /dev/zero
fi
Using these scripts, the VNC Server is started on chroot mount and stopped on chroot unmount. You can still leave and enter the chroot keeping the VNC Server running.
Hi all. I recently upgraded and was having a heck of a time trying to find out how to install java6 on the new Mint 13 since they pulled all the PPA's due to licensing restrictions. These are the steps I took to get it installed and working with Mint 13 Maya. This SHOULD work for other flavors of Precise.
Open terminal and in it type:
Code:
sudo apt-get purge openjdk*
ENTER
Code:
sudo apt-get purge *jre*
ENTER
Open up synaptics package manager and do a search for JRE or any other java related packages, make sure they are uninstalled.
NOW.
Once you are sure you've cleansed your system of any other java muck that might conflict you need to download this script.
https://github.com/flexiondotorg/oab-java6/blob/master/oab-java6.sh
Alternatively, open up a plain txt file and copy this code into it. The download link will more than likely be more up to date, but i'm putting this here for shiggles. Name it whatever you want.

Whether you download the script, or if you make your own text file, you need to enable the executing permission bit. So change your directory to wherever you saved the script and then in terminal type this and hit enter:
Code:
chmod +x ./whatever_the_script_is_named
Then in the terminal run the script with:
Code:
sudo ./oab-java6.sh
or
Code:
sudo ./whatever_you_named_this_script
What this does, is build packages for your system and places them in a local repository for apt-get to install. This bypasses java anal retentive licensing bullsquash. So, now we need to install it with:
Code:
sudo apt-get install sun-java6-jre
ENTER
Wait for it to finish and ensure your version is correcty by typing:
Code:
java -version
ENTER
You should get an output similar to:
Code:
[email protected] ~ $ java -version
java version "1.6.0_32"
Java(TM) SE Runtime Environment (build 1.6.0_32-b05)
Java HotSpot(TM) 64-Bit Server VM (build 20.7-b02, mixed mode)
[email protected] ~ $
Hope this helps someone and I hope this is in the correct forum!
Im going to be editing this as it seems there's really no reason to purge OpenJDK from the system, I think. I'm also having some compiling errors so once I get those nailed down, I'll probably just write a guide detailing the entire setup/config for 12.04.
It works !!!
Thanks for posting this, this worked well.
Only thing I would like to add is that if someone is looking to add the java plugin to firefox, then they would need to manually create a link in the firefox plugins directory:
$ cd /usr/lib/firefox-addons/plugins
$ sudo ln -s /usr/lib/jvm/java-6-sun-1.6.0.32/jre/lib/i386/libnpjp2.so
$ ls -lrt
total 0
lrwxrwxrwx 1 root root 57 2011-12-20 11:05 libnpjp2.so -> /usr/lib/jvm/java-6-sun-1.6.0.26/jre/lib/i386/libnpjp2.so
Restart firefox, it should work now.
Keep It All!
Hi folks
I'll just chuck an alternative method in for good measure and one that I successfully on ubuntu versions 11.10 , 12.04 and 12.10 as well every other debian derivative
Add these three repositories like so.
Code:
sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu hardy main multiverse"
sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu hardy-updates main multiverse"
sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"
sudo apt-get update
You can then install both version 5 and 6 of the sun jdk and leave any existing installs in tact.
For extra beans you can install openjdk-7-jdk without any adverse effects - I ran the following
Code:
sudo apt-get install sun-java6-jdk
sudo apt-get install sun-java5-jdk
sudo apt-get install openjdk-7-jdk
After that you can use /bin/update-aleternatives to manage which version to use. for example
Code:
sudo update-alternatives --config java
This gives me the following versions of java to use as my "java" command
Code:
There are 4 choices for the alternative java (providing /usr/bin/java).
Selection Path Priority Status
------------------------------------------------------------
0 /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java 1061 auto mode
1 /usr/lib/jvm/java-1.5.0-sun/jre/bin/java 53 manual mode
2 /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java 1061 manual mode
3 /usr/lib/jvm/java-6-sun/jre/bin/java 63 manual mode
* 4 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1051 manual mode
Press enter to keep the current choice[*], or type selection number:
Pick which version you need/want to use and away you go, you can switch most of the applications on the java platform painlessy with this method this includes javaws, javah , javac , jdb. if you're working with android only javac and java is required however, so do the same for javac
Code:
sudo update-alternatives --config javac
see "/etc/alternatives" for a list of application which may have alternatives and obviously the man and help has full details and how you can manage applications I also think there is a Kde, Gnome front end for it as well.
I got the repo info for sun jdk 5/6 from google's Android AOSP build instructions

thank you!
Thank you! I've tried many other scripts and sites without success. I should have started with xda for this. Thank you again.
Script location update.
Just an FYI, the location of the script has change, as the author has also included it to install Java 7.
The new location is https github.com/flexiondotorg/oab-java6
NOTE: the script pasted in the OP no longer works as making the .deb file will fail unless you download the jce_poclicy-6.zip. (which the script deletes the next time you run it)
EDIT: I also tested this on Ubuntu 10.04, and it is working for both JRE and JDK
Can you confirm whether this method still works? I have followed the directions here and on the source.android.com website to install sun-java6-sdk and my ubuntu 12.04 is not finding the install package. When I run the update script the hardy repository is giving me 404 errors. Have things changed significantly since this was posted?

Hi There,
Yes I believe they have as I noticed the same thing just recently, Although I will be looking a bit deeper when I installl 13.10. You are better off using the webupd8 team oracle java installer now I think, additionally AOSP master branch doesn't build anymore with the sun java version.

which java version is worth using then? Openjdk v6, 7 or 8? I am considering trying to build CM 10.2 and I see they recommend to use Openjdk. Any thoughts?

I haven't use the openJDK offerings so I couldn't recommend one, I'm afraid. However, I did a little moreresearch google search into Hardy's disappearance. it turns out Hardy Heron 8.04 was EOL'd in May [ Announcement on the Ubuntu Fridge ]
All is not lost though as the hardy repos have just been moved to http://old-releases.ubuntu.com/ .
so if If you really need the sun java6 jdk or even sun's java5 jdk you can add these lines to you /etc/apt/sources.list and they should install fine.
Code:
deb http://archive.canonical.com/ lucid partner
deb http://old-releases.ubuntu.com/ubuntu hardy-updates main multiverse
deb http://old-releases.ubuntu.com/ubuntu hardy main multiverse
However as previously mentioned the sun java6 jdk no longer builds the master branch of the AOSP but at least the correct links are there for future reference. Currently Webupd8 team have the latest (now) oracle's version of the java6 jdk which is what I currently use for building. So to install oracle's versions of the jdk, do the following
Code:
sudo add-apt-repository --yes ppa:webupd8team/java
sudo apt-get install oracle-java8-installer
sudo apt-get install oracle-java7-installer
sudo apt-get install oracle-java6-installer
Obviously you can use update-alternatives to switch between them as/if required and make's the question of which is worth using/installing kinda moot ... Install them ALL! I haz every java. lol
Thanks

Your prompt takes too much space, and it contains date + time, which are already shown on the screen (top and bottom).
Just make the prompt PS1='\e[34m\[email protected]\h:\w \$ \e[0m' so it's ready for cut&paste, e.g. when you're copying files with scp.
pivotce.com informs that instructions have been published on gaining root access to a webOS TV. This is much harder than on the old phones and tablets. When this was done on legacy webOS, there was a wave of enhancements and tweaks made available to phone users from webOS Internals and other developers.
The instructions can be found on the Russian webOS forums here: webos-forums.ru/topic4650.html (English Translation via Google).
As the thread itself notes, this creates the possibility of fiddling with your TV in a way that may turn it into a large, thin brick and will almost certainly invalidate your warranty. The general user should stay well clear of this.
pivotCE published this for information only and recommend leaving investigations to those who know what they are doing or who can afford to wreck expensive television sets. We will watch to see if anything interesting emerges from this development.

Detailed analysis of the root access method described above:
forums.webosnation.com/lg-webos-tv/331754-pivotce-seems-webos-tv-has-been-rooted.html#post3450911
Hello!
I'm from webos-forums.ru. I've root on TV for a while and can help you with translation or testing on LG webOS 1.4.

1. You need to install Developer Mode App and export private ssh-key with CLI (webostv.developer.lge.com/develop/app-test)
2. Convert private ssh-key with puttygen [import key <your private ssh-key>, then save private key]
3. Download exploit (zalil.su/6937580), then connect with TV User: prisoner, [<ip-tv>:9922] + private-key with WinSCP (or other SCP-client), upload to /media/developer on TV and rename it to root.
on linux
Code:
ssh -i <your private ssh-key> [email protected]<ip-tv> -p 9922 "/bin/sh -i"
4.
Code:
chmod +x root
Code:
./root
5. After try install any app from market go to LG App Store and try to install any app.
6. if third stage ok. the insert password 1111 as said.
7.
Code:
busybox chroot /proc/1/root
Code:
[email protected]tTV:/# id
Code:
uid=0(root) gid=0(root)........
I personally use Linux Subsystem on Windows 10 for all of this.
To install .ipk app:
Code:
ApplicationInstallerUtility -c install -p /tmp/<any-name>.ipk -u 0 -l /media/developer -d
Info about your linux kernel and TV firmware:
Code:
luna-send -n 1 -f luna://com.palm.systemservice/osInfo/query '{ "subscribe": false }'
Launch app:
Code:
luna-send -n 1 -f luna://com.webos.applicationManager/launch '{"id": "netflix"}'
All apps ID you can find with
Code:
luna-send -n 1 "palm://com.palm.applicationManager/listLaunchPoints" "{}"
or at a folder /media/cryptofs/apps/usr/palm/applications/<App ID>/appinfo.json
For permanent root access through telnet:
1)
Code:
[email protected]:/# mkdir -p /media/cryptofs/root/etc
2)
Code:
[email protected]:/# cp -r /etc/* /media/cryptofs/root/etc
3)
Code:
[email protected]:/# mount -o bind /media/cryptofs/root/etc /etc
4)
Code:
[email protected]:/# passwd root
Enter any new root password
5)
Code:
cp /media/cryptofs/apps/usr/palm/services/com.palmdts.devmode.service/start-devmode.sh /tmp/start-devmode.sh
6) Download with WinSCP start-devmode.sh and edit it locally.
You need to add at the beginning
Code:
mount -o bind /media/cryptofs/root/etc /etc
telnetd -l /sbin/sulogin &
Plus you can add the line to launch any App at start, e.g:
Code:
luna-send -n 1 -f luna://com.webos.applicationManager/launch '{"id": "netflix", "params":{}}'
And comment Dev Mode online check.
Here it's mine start-devmode.sh. It's for webOS 1.4. It can be different for other webOS versions:
Code:
#!/bin/sh
mount -o bind /media/cryptofs/root/etc /etc
telnetd -l /sbin/sulogin &
#luna-send -n 1 -f luna://com.webos.applicationManager/launch '{"id": "netflix", "params":{}}'

Is there anything hack related that I can do with this to and can is support a new air mouse with a dongle
Ok, so I get run the root app and first ,second , and third stage all are good. then it says try get root password is 1111. But the terminal keeps freezing after that happens. A couple times my tv rebooted too. I cant figure out what i could have messed up. ANyone with any experience using this method have any legit information?

I tried it stil seems to finish step 3 then says enter 1111. But this is where it freezes up and does not get any further.
Is this still working on 3.6? I'm stuck at try to install any app from market.

Which TV and firmware version?
Is this possible with UJ63 serie?
Hi, would the root access allow somehow to connect other bluetooth devices different than LG? Thanks!
You can do pretty much anything to the system with root, even include support for unsupported devices in form of additional kernel modules.
For example, I've added Samba support so I can mount use my NAS (see my blog at ddscentral dot org for details).
Hey guys is it possible to install android apps into WebOS? I just bought an Lg oled LG 55EG9A7V i want to use Perfect Player IPTV but i cant install it right now...Other then that i dont need anything else..
Can anyone help me?
Basically what I want to do is convert this into batch script for windows and by using Linux Binaries from Sourceforge create a script that basically does the same thing except it doesnt have to be pushed into my Phone's system it works directly in windows using ADB commands!
The script in question looks like this
Spoiler: THIS Script
Bash:
#adb shell mkdir /data/media/0/PartitionImages
#adb push .\backupPartitions.sh /data/media/0/PartitionImages/backupPartitions.sh
#adb shell chmod 0755 /data/media/0/PartitionImages/backupPartitions.sh
#adb shell /data/media/0/PartitionImages/backupPartitions.sh
#adb pull /data/media/0/PartitionImages .\PartitionImages

I tried by guidelines from an "Appendix N. Converting DOS Batch Files to Shell Scripts" from another site to turn the shell script variables into batch script ones but since I got no experience with either of them my attempt turned into an amalgamation of the two's code in one..

additionally I have pretty much all linux commands's binaries on the same folder as the .bat script so as long as the syntax is correct and nothing finniky going on it should work technically but since I got no experience I can't do this on my own...

I have tried that script itself and it failed at "DM-Verity" and SELinux enforcement also for some reason no logs at all in temp folder
