[Tutorial] Boot Linux on the Typhoon

Started to mess about with this earlier today, finally got the damn thing to work Turns out it is quite easy..
First, to get one thing straight, this will only boot the kernel, it will dump you at a shell which you have to remotely log on to via telnet over usb. There will be some (not so) fancy text appearing on your phone's screen but that is about it. Also, it only works on unlocked phones.
This is what you get:
On your computer you'll get this:
Cool, huh? Btw, this is running from a memory card, your OS will be untouched so as soon as you reboot the phone it will boot right back into WM2003/5/6.
1. What you need
* A HTC Typhoon running any rom of your choice (I did it on WM6).
* A miniSD memory card
* A Linux distro - I downloaded the Ubuntu Live CD and ran it through VMWare, no need to install anything or reboot your computer.
* miniSD image of Xanadux - this is the linux port for HTC devices. Grab the latest version here: http://rapidshare.com/files/92218185/Linux.zip.html
(these files are extracted from the miniSD image file found here: http://vivien.chappelier.free.fr/typhoon/download.html)
2. How to run linux on the Typhoon
1. Instead of installing linux properly on your phone which requires partitioning of the internal memory etc (a lot can go wrong) we'll put it on the memory card then a Windows Mobile program called HaRET will boot linux for us from WinCE. Completely non invasive in other words.
This bit is dead easy, just extract the Linux.zip file you just downloaded and copy the files to the root of your memory card (must be memory card, can't do this from the internal memory afaik). Next, go to the File Explorer on your phone and find the file HaRET.exe. Run it then press the run button (this button has focus when you execute HaRET.exe so just press the joystick when the windows appears) and you will see a message saying "Booting linux", then after a few seconds your screen will go black and some text will appear.
Voila! That's linux running on your phone!
2. Connect to the phone via telnet
If read the last line of text that appeared on screen you'll see that it says "Press enter to activate this console" but no matter what buttons you press on the phone nothing happens, some gibberish appears but that's it.
Solution: telnet to the phone from your computer.
Get Ubuntu to boot on your computer, then go to Applications->Accessories and run the Terminal. Next type in the following commands:
Code:
modprobe cdc_ether
modprobe usbnet
ifconfig usb0 up 192.168.9.1
and finally
Code:
telnet 192.168.9.10
Login with username root and you'll find yourself at a shell like the screenshot above. Everything you see from now on is coming linux from your phone!
I've noticed that Xanadux doesnt always initialise the USB port unless it is connected via USB when booting up so make sure you always have your phone connected via USB when you run HaRET.
Now I'm going to try to figure out how to get the GSM module to work...

LINUX based ROM??
Hi shandar,
I have read your post and I am interested to know if you are cooking a LINUX based ROM that will run in a WIndows Mobile device? That would be too good to be true.
Also another question is do you need to have Linux running on your desktop to make this tutorial work?

Hey, well, I don't know enough to make a linux rom for smartphones. I'd love a working linux distro for Typhoons & Windows Mobile phones in general but it is way out of my league unfortunately.
Btw, I probably should clarify that I only wrote the tutorial, the actual linux port is made by someone else.

Ubuntu LiveCD with ADB and Unrevoked Recovery installer(Guide).

I have been helping out with rooting HTC Aria's over in IRC in the #liberatedAria channel for a while now. A lot of people have problems with drivers on Windows. The easiest solution for them to do this has been to download an Ubuntu LiveCD and use it to root their phone, however many people know nothing about Linux at all and feel daunted by this.
I have created a customized Ubuntu LiveCD that has a script that downloads the Unrevoked Teams reflash, untars it, and runs it as root to root HTC's phones that are supported by the tool (HTC Evo, Hero, Aria, Desire, and Incredible). It also has the Android SDK included and added to the path so it is accessible from a terminal. Everything can be done without a single change to the computer you are doing it on.
Download the iso image here:
MD5: 9a34c343e8f610e66674af9384334bf6
ubuntu-10.04-desktop-i386-HTCROOT.iso Primary
ubuntu-10.04-desktop-i386-HTCROOT.iso FileFactory.com
Burn the iso to a cd (This can be done with any cd burning software, imgburn found here is free)
[Optional]
If you do not have a CD drive, you can create a bootable flash drive by using the tool found here:Pendrive Linux
Put the CD into your computer cd/dvd drive and reboot your computer.
You must make your computer boot from CD, there are many different ways to do this depending on what computer you have, most recent computers have this enabled by default. Here is a guide that may help if you can't get this to work:Enable Boot from CD
Once it boots from the cd it will show a small picture of a keyboard and a person, do not press anything here and it will come to a window that will allow you to select your language.
Select your language and click "Try Ubuntu 10.04 LTS". This will boot up to a standard Ubuntu livecd desktop.
On your phone click menu, settings, applications, development, usb debugging
On the computer click "Places" on the top menubar and click "Home Folder". This will open a file explorer window, in that window is a script called "reflash.sh".
Double click reflash.sh. A window will pop up asking you what to do with this file, click "Run in Terminal". This will go get from the internet the current version of Unrevoked recovery installer from unrevoked.com/recovery, unzip/tar it, and run it as root.
Once it is complete you will be looking at the unrevoked3 screen and you should follow the prompts on screen.
You will then follow the prompts on the screen to plug in your phone, from the notification pane in android select charge only.
unrevoked3 will reboot your phone twice and leave you in ClockworkMod Recovery. On the computer at the bottom of the window it will say "Done".
Close the window, if you do not need to do anything further you can shut down the machine and be back in windows with nothing changed on your windows system.
Congratulations, your phone is now rooted and has ClockworkMod recovery installed.
There are other guides to setup of sideloading for the aria as well as how to load roms. You can do these using this live cd as well, this is a full ubuntu 10.04 livecd with only games and open office removed, and the unrevoked3 installer and the android sdk installed, it is already in the path and you can use adb commands from the terminal without having to switch directories(however it can be found in /opt/android-sdk-linux_86).
I would like to thank The Unrevoked team for making such a nice tool, and website that made this possible. I would like to that the guys in IRC on Freenode.net channels #liberatedAria and #koush for everything I've learned recently as well as all the great work they have done. Thanks also to Attn1 for making some nice roms for the HTC Aria and gave me the idea to create this. Thanks to Downer3d for the torrent mirror. Thanks to Neolobster for the new faster mirror.
Allowing Non-Market Apps using this cd on the stock ARIA rom:
Click Applications in the upper left corner.
Go to Accessories, click Terminal. This will put in you a terminal in the default users home folder. Because ADB(and android sdk) are in the path you do not need to change any directories. Start the phone in CLockworkmod with data mounted from the partitions menu and plug the phone into the computer.
Code:
sudo su
adb pull /data/data/com.android.providers.settings/databases/settings.db settings.db
echo "update secure set value = 1 where name = 'install_non_market_apps';"|sqlite3 ./settings.db
adb push settings.db /data/data/com.android.providers.settings/databases/settings.db
adb reboot
What this does:
Switch user to root.
ADB pulls the file that contains the setting to allow non market apps down to the machine from the phone.
The next line runs a sql update of the field install_non_market_apps in table 'secure' and sets the value to 1 (on).
ADB then pushes the file back to the phone in its original location.
You then use ADB to reboot the phone to enable it.

Thats awesome!! If I didnt already go through all the trouble of doing it on my Windows box I would definitely try your live CD. I already have 10.04 installed on my laptop and I never really thought of trying it on there. I wonder if it would have been easier....oh well. Thanks again. Im sure there are plenty of people out there that will find this very useful.

Much easier. And yes, this IS awesome. Great job, Shad0wf0x. This kicks ass.

This is a fantastic idea, I had a ton of trouble rooting my Aria on Win7 x64 and downloading and using Ubuntu 10.04 eventually proved to be much easier. If your iso works as advertised I can see this possibly being the most pain-free solution for annoyed Windows rooters.
Sent from my HTC Liberty using XDA App

This works wonderfully for rooting and sideloading apps (the only issue there was figuring out I needed the root account and permissions). As painless as a dentist trip.
If I was to install Ubuntu from that LiveCD, would it still have the Android SDK on it or would I need to reinstall it? I like not having to cd to it.

the android sdk is installed on the livecd and in the path, you'll have it every time you boot up, the part the script downloads will be gone on a second boot(unrevoked.com's recovery installer)

Great job!
Do u think that u could add some other HTC devices, in the future?

Awesome, thanks!

it says in your signature you have 2.2 updated OTA, that must mean you have an evo, and those aren't supported by the unrevoked tool when running 2.2.

awesome shortcut for rooting phones, however I followed the steps and it is saying that the hero is not supported at this time? Did i do something wrong, I'm running 2.27.651.5

I've burned the the iso file to a cd but I'm not able to get the boot-up to work correctly..or to come up at all, when re-booting windows.

@lcw
When you boot, you will need to hit your bios and select your CD drive as a boot device. Then enjoy the ride - easy as falling off a bike.

I cannot get my dell d600 or d630 to boot. The CD spins but I get the message "No bootable device".
I verified that the ubunto_*HTCROOT.iso file 641,942 kb is the only file on the CD.
Can someone please help.

You're not supposed to burn the ISO file onto a disc as a file. You're supposed to burn the contents of the ISO to a disc.

I attempted to boot from the CD, I get the person/keyboard screen then i get the Ubuntu screen, then my computer goes black, any solutions?

This is the BEST way to root your Aria. Big props to everyone that helped create it. You guys are the best.

androidVNC to webtop

I have the idea that Just as the Ubuntu hacks for android work, we could use androidVNC to connect and view the webtop from the phone without HDMI or the dock, using the phones screen.
Another thing is many of us are using SystemR89's ubuntu hack, with Gnome or LXDE so then all we need is to have tightVNCserver installed as well in the Ubuntu eviroment. Do the steps provided in the above site androlinux.com and trigger that Ubuntu Session to start and then connect on loopback should work.
As I recall ubuntu.sh sets up the soft links or Binds. I don't recall what Booubuntu does but it appears to chroot you to the Ubuntu enviroment for install of the rest of the packages.
I don't think we need to mess with those, they have been done by SystemR89's WebtopMOD. We just need to Chroot to the Ubuntu.disk and give the command "export USER=root" and "vncserver -geometry 1024x800" to start the VNC server Then connect via AndroidVNC.
You'll note that our Phone already has a ubuntu.sh on the root directory. Evidence that moto basically copied the work??? IDK.
I'm looking for some ideas or help from someone who knows ubuntu better then me on how to do this.
I'll hack at it a bit and see if I can get anywhere.
I doubt too many people will find this useful, maybe I'm wrong though. If it would be helpful to you let me know, it will add to my drive to figure it out.

[GUIDE] Running Debian Linux on Xperia X8 (chroot)

First of all please notice, that this is not my own development project, it is just a port of the guide for HTC G1 from http://pdaclub.pl/forum/htc-dream/%28how-to%29-instalacja-debiana-%28na-g1%29/ for Xperia X8.
Please be aware, that this solution has been only tested with one Xperia X8 device running Floyo 0.30 (thanks to Racht for this great ROM !). I cannot guarantee that it will work on every other custom ROM as well as on the stock Xperia X8 ROM's.
Please also notice, that instructions in this tutorial in some cases can brick Your phone. I'm not responsible for any damage to the software or hardware caused by this tutorial. You can follow the instructions from this guide but only at Your own responsibility!
Please also notice, that I'm not an Android Developer. I'm just a user with some knowledge about Unix, so don't blame me if this tutorial won't work for You. You can post Your problems and we'll try to solve it together.
OK, I think that's all for the intro .
TABLE OF CONTENTS:
1) The purpose of this guide
2) Requirements
3) Things to prepare
4) Installation
5) Some known bugs
6) Some little tips
1) The purpose of this guide.
This guide reffers to the newbie users who want to run Debian Linux on their Xperia X8. Step by step I'll try to explain how to run Debian simultaneously (at the same time) with Android. To gain that we'll use a program/command chroot (http://en.wikipedia.org/wiki/Chroot) which will allow us to Run Debian in Android as something similiar to "virtual machine" on PC.
You may ask why to run Debian on Android device ?
There are several answers to that question:
a. For testing...
b. ...developing applications in for e.g. C/C++ for ARM platform and try to run them on Android OS.
c. Installing Linux applications (like web servers, WiFi cracking software) and test what is working and what isn't.
d. For fun
For those who are asking what Debian actually is - please refer to the page http://en.wikipedia.org/wiki/Debian.
2) Requirements.
Before continuing check if You and Your device meet the following requirements:
a. ROOTED Xperia X8 device (I recomend to have Floyo 0.30 by Racht ROM installed, because it was tested on this ROM. I don't know if it'll work on different ROM's.)
b. At least 800MB space free on Your SD Card
c. Access to PC computer
d. Basic knowledge about Windows command line and Linux shell
e. About 1 hour of free time to set up everything
3) Things to prepare.
a. Download one of the following packages:
http://rapidshare.com/files/327504536/debian750.rar
Click to expand...
Click to collapse
or
http://rapidshare.com/files/327491605/debian1.5.rar
Click to expand...
Click to collapse
These are the packages containing Debian drives image as well as all other files needed to install Debian on Android. The only difference is that the first one is 750MB and the second is 1,5GB. The second one is for bigger SD Cards, you'll get more free space in Your "virtual machine" after running it.
b. ADB Shell (can be found in Android SDK in folder platform-tools\ - http://developer.android.com/sdk/index.html)
c. SSHDroid from Market (only if You're planning to connect to Your Debian via SSH)
d. PuTTY for Windows (only if You're planning to connect to Your Debian via SSH - http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html)
e. ConnectBot or Terminal Emulator from Market (it's a good terminal application)
The bold items are necessary.
4) Installation.
PERFORM A FULL SYSTEM BACKUP USING XRECOVERY BEFORE PROCEEDING ANY FURTHER !
Now the best part !
There are several ways to install Debian:
1) Some are using Terminal Emulator application (preinstalled in Floyo 0.30)
2) Others are connecting with phone via SSH
3) But some are using adb shell command from Android SDK and that's the way we'll do this, because I know there are some differences between using adb shell and other ways. I tested it with adb and it is working so I think it is the right choice.
First, unpack the *.rar file of Your choice (debian750.rar or debian1.5.rar) to Your hard disk on a PC.
Replace file bootdeb which can be found in Debian folder after unpacking the archive with the one from bootdeb.zip file attached to this post. You need to do this, because the bootdeb file which is in the archive won't let You boot Debian correctly. It'll only cause Xperia X8 to restart after few seconds since execution. The file in bootdeb.zip has been corrected by me and it allows to boot Debian without any (known ) bugs.
Copy the Debian folder from the archive directly to the SD Card (also known as a root directory of Your SD Card). You should have the following directory tree on Your SD Card visible in Xperia X8:
/sdcard/Debian/bootdeb
/sdcard/Debian/debian.img
/sdcard/Debian/installer.sh
etc...
Click to expand...
Click to collapse
Enable USB Debugging in Xperia X8. To do this go to Settings->Applications->For programmers and check USB Debigging.
Connect Your phone via USB and don't mount the SD Card (just like You want to charge the phone via USB).
On Your PC click Start->Run, type cmd and cd to the directory where You installed Android SDK, then cd to platform-tools and execute command adb shell. After execution You should see a # symbol in the command line window like on a below screenshot:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Now execute the following commands in ADB ahell on PC:
su
cd /
sh /sdcard/Debian/installer.sh
Click to expand...
Click to collapse
And You shoul get something like this:
VERSION 2.1
Custom Debian Bootloader is now installed! Quick huh?
etc...
Click to expand...
Click to collapse
And it's done ! Debian Linux has been installed.
Type in ADB Shell command
exit
Click to expand...
Click to collapse
As many times (I guess 3) until command line window disappears. Disconnect Your phone from PC and unplug the USB cable.
Now let's try to run Debian - on Xperia X8 run ConnectBot or Terminal Emulator and type:
su
sh /sdcard/Debian/bootdeb
Click to expand...
Click to collapse
Remember to allow the terminal application to run as a superuser.
After a while You should see a screen similar to the below screen shot:
I removed the lines (blured section) which You won't see after first boot. I have them, because I installed Apache Web Server and it is starting at the logon .
As You can see we are logged into Debian Linux !
Now, execute the following command:
/scripts/onetime.sh
Click to expand...
Click to collapse
It's necessary only after first logon. It'll let You to set up root password (only for Debian, not for Android) and do some more stuff (actually I didn't even check what this script is doing - forgive me).
And it's done... Now You are on Your own with Debian installed ! Go, play around, because it is a fully functional operating system for Your demand .
What about the performance ?
My Debian is still working since one day in the background (minimize the Terminal Emulator window after logging in) and I haven't suffer any problems with the low performance yet. I even set up an icewm window manager and VNC Server to be able to log in to my machine via VNC client and see the desktop and it isn't too laggy . But that's only a stupid future. The most power we get because of the access to Linux Shell (the command line which let us to use Linux applications on our Xperia X8).
4) Some known bugs.
For Your own safety read this short section.
1) Better don't try to unmount the SD Card from Xperia X8 (for e.g. when mounting the phone to the PC) when Debian is running. I didn't try this yet, but the bootdeb script is creating something called loop device in the Android system which should be properly unmounted. If this device will wanish due to some user activity the phone may not boot correctly any more.
2) When You finish playing with Debian always use the exit command to safely unmount the loop filesystem. After exit Your phone needs to be rebooted, better don't try to override this setting.
3) If somehow You will loose connection with Debian in Terminal Emulator You always can run:
sh /sdcard/Debian/bootdeb
Click to expand...
Click to collapse
And log in again. You'll just receive several errors on the boot screen, because the script will try to mount already mounted file system.
5) Some little tips.
1) After first logon execute the following commands:
cd /etc/apt
nano sources.list
Click to expand...
Click to collapse
And in the opened text editor add these lines (do not overwrite the file contents):
deb http://ftp.debian.org/debian lenny main contrib non-free
deb-src http://ftp.debian.org/debian lenny main contrib non-free
Click to expand...
Click to collapse
After this execute the command:
apt-get update
Click to expand...
Click to collapse
It will update Your applications repository available for Debian.
2) Running Apache Web Server:
Execute command:
apt-get install apache2
Click to expand...
Click to collapse
To install Apache Web Server. When the installer asks You if You want to proceed with the installation type Y.
After installation run command:
/etc/init.d/apache start
Click to expand...
Click to collapse
And then You can try to connect to Your phone on port 80 using HTTP browser and see if there's a message It works! .
3) Uploading files to Your Debian "virtual machine":
Install SSHDroid from Android Market.
Download program WinSCP and connect to Your device on port 22 using root as a user name and admin as a password.
After connection open location /data/local/mnt and You'll see Your Debian file system.
I think that's all for now.
I hope this guide will help "newbie" users to run Debian on their phones.
If You have any more questions or problems please let me know.
Regards,
Chris.

you should post this on development!

At the moment it's a little fiddling. Start phone -> connect bot -> su -> sh /sdcard/Debian/bootdeb -> from there I should be able automat anything
How can I use some kind of autostart?
Why I lose connection in ConnectBot when I disable mobile internet connection? Doesn't make sense to me. Mobile internet has nothing do do with local shell, or?

Hi kingsize623!
As I said at the begining this script is highly ROM-dependent. It can run on some ROM's, but on the others there will be many problems.
I suggest You to edit file /sdcard/Debian/bootdeb in some text editor (I suggest Notepad++), locate the line:
busybox mount -o loop,noatime $kit/debian.img $mnt
Click to expand...
Click to collapse
(it should be line 47), and change it to:
mount -o loop,noatime $kit/debian.img $mnt
Click to expand...
Click to collapse
This should help. If it won't, there can be a lack of some module in Android on Your device which will prevent the script from running (no loop support for e.g.).
If You'll face some further problems let me know.

Hi bagers!
Thanks for the comments on this post !
First of all, You're right, maybe I should post it on Dev section, but I didn't use XDA-DEVELOPERS much in the past, so I was afraid I may get kicked because of such information from "newbie user" in Dev section. This section (in my understanding) is for Android guru's, and I'm not one of them .
As for the autostart: the only thing You can automate in my opinion is the part where You type:
su
sh /sdcard/Debian/bootdeb
Click to expand...
Click to collapse
The only thing You need to do is to write a simple script which will look like the following:
su
cd /sdcard/Debian/
sh bootdeb
Click to expand...
Click to collapse
or
su
sh /sdcard/Debian/bootdeb
Click to expand...
Click to collapse
Name it for e.g. startdeb and place it in /system/bin for e.g. (I think bash will look for files in this directory by default, but I'm not sure about that).
Now, everytime when You'll try to run Debian, just open ConnectBot and type startdeb - this should automatically make You su and execute the startup script.
As for the dissconnections issue:
As far as I can see this problem exists on Floyo 0.30 as well. I'm not yet sure why it acts like that.

As I wrote in previous post - try modyfying the startup script.
You also should have Busybox installed (if You don't have it download it from Market).

I installed also sshdroid and connected to the phone from Windows 7 using Putty. But, when I disconnect putty, then I will also see this "Rebooting device to ensure clean takedown.".
Ehrm, I just wanted to disconnect putty, not to shut down debian. Another bug?
Can you disable all this "Rebooting device to ensure clean takedown.", it's really disturbing.

Now, everytime when You'll try to run Debian, just open ConnectBot and type startdeb - this should automatically make You su and execute the startup script.

Okay, I done that and something really strange happened.
I made a files called "sd" in /system/bin with content:
su
sh /sdcard/Debian/bootdeb
Like you said.... But when I type sd in ConnectBot then, debian will start, and then the phone will restart...
But, when I type su and sh /sdcard/Debian/bootdeb, manually in ConnectBot, then debian will start with no error. Strange, huh? Any idea? Bug?

As far as I can see this problem exists on Floyo 0.30 as well. I'm not yet sure why it acts like that.

I installed also sshdroid and connected to the phone from Windows 7 using Putty. But, when I disconnect putty, then I will also see this "Rebooting device to ensure clean takedown.".
Ehrm, I just wanted to disconnect putty, not to shut down debian. Another bug?
Can you disable all this "Rebooting device to ensure clean takedown.", it's really disturbing.

Hi again !
There are lots of bugs as I can see . But... If You're connecting from Putty don't be surprised that the phone is rebooting after closing Putty window. It works like that:
1)You're running the sh /sdcard/debian/bootdeb from Putty - Putty is the only terminal for the script.
2)When You dissconnect suddenly the only terminal which was preventing the bootdeb script from running wanishes so the script continues working (so it's jumping to reboot section). That's not a bug, it was written to work like that.
I don't suggest You to disable the rebooting - it helps You to have a clean unmount. If You override this, strange things may happen when You'll boot for the next time, but it is not sure for 100% - check it for Yourself .
As for the not working script file - I thought that su command won't work in the script. That's why the bootdeb script doesn't already have it included.
If You want to know about some more bugs:
Don't try to set up OpenSSH on Debian - it won't work.
Don't run FTP server like proftpd or vsftp - port 21 is forwarded correctly, but port 20 is not, and that's why FTP is not working.
There are many bugs, but if You'll follow simple rules You won't have any problem with using Debian.

Can you think of some workarround in order to use Windows+Putty+Disconnect+Nophonereboot?
I really like to use that phone now as a server, because the power consumption is very very little (compared to a PC server). All time connected to charger (~3,5 W) would only coast me around 5 or 10 Eur per year. l So I plan to run Debian on the phone at all times and from time to time to administer my "server" using Putty and WinSCP.
But of course, at some time I'll have to quit Putty (and WinSCP)...
The problem is, that SSHDroid runs "outside" of Debian. The ssh would need to run "inside" Debian. You already told me not to try OpenSSH. Do you know any alternative to OpenSSH or an alternative protocol? Connect and remote administer by anything else, vnc server maybe (vnc for console?), but not ssh.

The workarround is very simple. As You said SSHDroid works on the "outside", but I'm telling You that it can work in the "inside" of Android as well. I tried to use X8 as a web server so this solution has been tested.
1) Run SSHDroid
2) Connect using ConnectBot to [email protected] and run:
su
sh /sdcard/Debian/bootdeb
Click to expand...
Click to collapse
You'll have Debian on the phone already started.
3) Connect to Your phone via Putty with Debian started in ConnectBot and type:
chroot /data/local/mnt /bin/bash
Click to expand...
Click to collapse
It will connect to the virtual Debian on Your phone and will let You to administer it, but on the second side it won't even touch bootdeb script which is annoying You so much, so the phone won't restart after logging off from Putty, because the "main" session will be still held by ConnectBot on the phone.
The only thing You need to remember is to safely kill Debian when You'll want to restart the phone using exit command in ConnectBot (which will cause the phone to restart as usual).
As I know, You'll very soon tell me, that there's a bug - don't let the Android device to go to "sleep" (turn off the screen), because the performance of the "server" will get very low because of lower CPU speed in sleep mode.
Hope it'll help

As I wrote in previous post - try modyfying the startup script.
You also should have Busybox installed (if You don't have it download it from Market).

Hi !
I guess there's some problem with GingerDX.
To Deinstall Debian You just need to delete the Debian folder from /sdcard/ . Nothing has been installed into /system/.

He instals a custom boatloader right?
Mayby it doesn't work with gingerdx becouse he restarts after the gingerdx logo but before the cyanogen mod 7 logo, i don't know how to name it

No - if I am not completely wrong - the real bootloader of the x8 will not be changed in any way.
The debian bootloader is only needed to start debian inside android.

Don't panic, as long as you did not mess with the bootloader, you can always rescue your device.
I also bricked my device once, could not even get to xrecovery. Read this post.
http://forum.xda-developers.com/showpost.php?p=13341271&postcount=2
No worry, with PC Companion and repair (you'll loose all data) you will be able to recover your phone.

My phone has GPRS and WiFi enabeld at the same time.
Is it possible to tell the a few selected debian processes "use only GPRS, no WiFi"?

Afaik - from my knowledge from reading and searching the forums alot - a permanent (must send to se to repair) brick is only possible if you want to use the new cracked bootloader and mess up something.

Ipython/Jupyter Notebook on Android

Hello All
I was able to successefuly install Ipython(jupyter) on my nexus(2013) and wanted to share the procedure with all that could be interested.
You could learn and read about Ipython[Jupyter] here
CAUTION:
> To the best of my knowledge this is the first tutorial of it's kind.
> I strongly recomend that you try this on a fresh rom. Use MultiROM for instance
> This was tried on Nexus 7(2013) with android 4.4.4. But I see no reason why it shouldn't work on lolipop 5.0 or on another android tablet. [You could try at your own risk and report your findings]
> Allow minimum 4Gb free space. I used rougthly 2.2 Gb, but i installed more than just ipython
> Hackers Keyboard is VERY HANDY if not NECESSARY
> I apologize for typos and gramar mistakes in advance
> Some of the following steps take time (a long time). Just make sure your tablet is connected to the charge and chose to keep the screan ON while it's on charge
> I am UNLOCKED and ROOTED. I can't tell whether it is required. If it is it would have to be with the prerequired apps. YOU WANNA VERIFY THAT before anything
> MOST IMPORTANTLY, DO THIS AT YOUR OWN RISK. I'm NOT RESPONSIBLE for any INCONVENIANCE whatsoever.
Procedure:
1-: Install GNURoot WheezyX . I am more confortable with debian, tryFedora or Gentoo ... If you know what you are doing.
2- Install GNURoot
3- Open GNURoot
4- Chose wheezyx (or fedora or gentoo ... depending on the distro you like) in the "Select Rootfs to Create " drop-down menu.
5- Click on 'Create New Rootfs' button
6- Chose wheezyx(or fedora or gentoo ... depending on the distro you chose) in the "Select Rootfs to Launch " drop-down menu
7- Check 'Lauch as Facke Root' box. This will give us root privilege
8- Click on 'Lauch Rootfs' button
At this point you shoud have 'Terminal Emulator" open up a window with '[email protected]:/# ' and a prompt ready to take instrucktions
Welcome to linux !!!
Now we need to install "python" and "pip", but before that we need to install 'build-essentials' which will make 'gcc' and all tools required to build a package available on our linux platform:
In the following: if you chose wheezy distro it's the same procedure; if you chose fedora distro replace apt-get with yum; if you chose gentoo you are on your own because I'm not familiar with it
Anyways I assume no responsability anyhow whatsoever.
9 - At the prompt type 'apt-get update' and press Enter
10 - Type 'apt-get upgrade' and press Enter'
11 - Type 'apt-get install build-essential' and press Enter' : This will install "build essential"
12- - Type 'apt-get install python' and press Enter' : This will install "python". I got the version 2.7.3 . You could find the version you installed by typing "python -V" and pressing Enter
13 - Type 'apt-get install python-pip' and press Enter' : This will install "pip", the python package manger
At this point we have python setup in the linux environement. Let's finally install ipython:
14-a Type 'pip install ipython' and press Enter if all you want is the ipython interpreter
15-a Type 'pip install ipython --upgrade' and press Enter to make sure you got the latest version
or
14-b Type 'pip install ipython[all] ' and press Enter if you want ipython and all the goodies like notebook
15-b Type 'pip install ipython [all]--upgrade' and press Enter to make sure you got the latest version
I do scientific work with ipython, so if you are on the same boat as me you could install scientific packages numpy,sympy,pandas,nose,.... with:
"apt-get install python-numpy python-scipy python-matplotlib ipython ipython-notebook python-pandas python-sympy python-nose" !!! This is a lot about 1.2Gb !!!
At this point everything is set up. "when the wine is drawn, we now just have to drink it"
16-a Type ' ipython ' and press Enter to run ipython interpreter
or
16-b Type ' ipython notebook' and press Enter to run ipython notwbook. If you get an error message say that ''no web browser could be found" ignore it. look for the server address (looks like http://localhost:8888)
17-b Enter that adress (http://localhost:8888 in my case) in Chrome (I had no problem with chrom so far, but you could try on your favorite web browser) press Enter. Et voila you should be in the ipython notebook tree
I have been here for a couple of years, and never got to share anything.
This is my first thread, and i hope it is the beging of a very long series of contributions
> I will upload screenshots later to better guide noobs (I was one onece)
> PM me if you like to donate. I would appreciate it
> Please support the GNURoot developpers, or ipython[Jupyter] developpers if you can. They are all doing a terrific work. (I'm in no way associated to them, but love and support their work)
> I'm not very good at making videos, but I welcome any initiative.
You now Know how to install ipython, I trus you could be very creative since you now got linux at your finger tip :laugh:

Help to use pandas + matplotlib: no $DISPLAY environment variable
First of all thank you for this pretty cool tutorial
i did it and everything else works after all that huge pip installation!
my problem is that i need to see the result of my codes which sometimes is to show me plots of my data using the library matplotlib.pyplot
when i do that i get the following error:
TclError: no display name and no $DISPLAY environment variable
i found someone with the same problem in another situation (not on android but something like trying to save the plots in a pdf) and the problem was solved doing the import like this:
import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt
plt.plot([1,2,3])
plt.show()
By using matplotlib.use('Agg'), python knows to use the non-interactive back-end Agg instead of trying to display to the screen
this means that i don't have anymore the error but the plot won't be shown either
this happens not only when i do python file.py from command line but also when i run the same codes on jupyter notebook
so is there a way to execute file.py so they do what ever pandas want to do in this android environment (especially pop up windows with my plots when I execute the files)?
if there is no way how do i get rid of android to install some better OS on my tablet that can do all this kind of stuff?
thank you but all of this that you have done it's really not that useful if i cant see my plots
let me know!

You should know that the linux running GNURoot doesn't have an X-session. You kinda need x11 installed on it to be able to have windows popping up and showing your plots. I remember trying apt-get install x11 without success on "Wheesy". Now, I know there is the "wheesy X" distro of GNURoot, but I don't know whether the X stands for X-session capability; I suggest you try that. (I no longer have my nexus7 to try, but it would be nice to see what happens).
I was able to go around this problem by working on the notebook. I could see my plots fine. I remember firefox beeing the best browser to work on the notebook.

Plots at least on jupyter and transfer files
hey so i found this : (i dont have authorization to post links normally)
stackoverflow .com / questions / 18353203 / using-python-and-matplotlib-on-android
where someone is stating is a big deal to have plotlib working on android
jupyter notebook is not displaying plots not even on firefox, it always give the "TclError: no display name and no $DISPLAY environment variable". It would be awesome if you'd give me a straight solution so i can see plots on jupyter! that would be more than enough to follow lessons in class
the temporary solution i found for now is to remote control my pc at home from the tablet to do all the coding but i cannot work without connection this way
i also found out about this website Wakari but they are saying now there isn't anymore free space for new subscription..
the best solution would be to have plots displaying on jupyter with your help
so the plan for now is to stick to let the pc at home do all the work and remote control it with the samsung remote pc app or to find a good website to log in from the tablet and write codes on browser
ill still use this command line of yours when ever i can thou, when ever there is nothing to display i guess.. but how do I find the folders so i can move to the desktop computer the .py files or the notebook files i create? i was expecting to find the files when i was connecting the tablet with usb wire.. is there anyway to transfer those files?
thank you
