Debian working niceley on Desire.

Debian for Desire.
If you are able to try this on another android device, please do as I will be very interested in the results.

You will need.
-Root access.
-Busybox (included in most custom roms)
-1.4gig free on SDCARD
-VNC Client (ie. AndroidVNC)
-Terminal Emulator (ie. ConnectBot)
-7zip
Instructions
-Extract the file deSIREbian.7z on your PC using 7zip.
-Copy the contents (debian.img and deboot) to root directory of SDCARD.
-On your phone in terminal emulator type
su
sh /sdcard/deboot
Click to expand...
Click to collapse
You should get a blank screen showing "localhost:/#" after a couple of seconds.
-On your phone in your VNC client log in using these details
Password - password
Port - 5901
Click to expand...
Click to collapse
Nickname and Address are not needed, call it what you want though.
Changing the colour to 24bit and enabling local mouse pointer and full screen bit map are not neccesary but reccomended.
-Thats it.
Notes.
-You can log in via ssh, (gives a much better terminal, ie works properly with aptitude). Use [email protected] and password "toor"
-The version of Debian is Armel Lenny, installed using debootstrap.
-It is just the base package with LXDE on top, you only get a desktop, a file browser, an internet browser, and a pic viewer.
-If you want more packages there's tonnes of room on the image. eg apt-get install openoffice.org or apt-get install abiword or apt-get install any flipping thing u want
-You can access the SDCARD from Debian at "root/sdcard" (read-write)
-You can access Debian filesystem from Android (When Debian is running) at "sdcard/debian" (read only)
-debian.img is mounted at "sdcard/debian" using "dev/block/loop5"
-So far the only rom i have come accross that this dont work with is one of the cyanogen nightlies from last week. apart from that, working on opendesire, cyanogen, defrost, leedroid, official 2.2 with busybox...
Issues.
Debian cannot be shut down. You need to reboot the phone to do this. (You can kill the VNC server with "vncserver -kill :1" there is an icon on the festoons to do this.)
Update log.
deSIREbain.
-First release.
deSIREbain2
Fixed
-Loading a second terminal no longer breaks vnc.
-You no longer need to create the folder debian on sdcard.
Added
-ssh server (login with root and toor)
Removed.
-The image has been downsized from 2 gig to 1.4

Hey,

thx to mercianary for help

I found this guide quite helpful at getting a bootstrapped Debian setup running.
http://www.saurik.com/id/10
I didn't need to insert the ext2 module as it's already loaded for me, I guess G1s didn't have that convenience back then.

It looks like you had not installed busybox
Which ROM do you use ?

oh i'm sorry
i'm a newbie and don't really know what a rom is
but i had problems with busybox and there was a somebody who said i can get the app titanium and let it install the busybox

could you please show me a tut how to install busybox
maybe a german tut
thanks

dont know why that happened.. works on mine. syntax looks ok to me.
try with this one (attatched), it's the same but without the bit that's not working for you.
what rom are you using, i shall try to replicate the error so I can try to fix properly.

There should be a guide on installing busybox somewhere if you want to search for it, i know i remember seeing one a while ago.
Too be honest, your better off just flashing a rom that includes busybox, it would be MUCH easier.
have a look here and see what takes your fancy, I would recomend defrost, because it is stable and easy to overclock.

Thanks mercianary,
It works fine!,
I use customised DeFroST_0.9b_uvonly with USB-host patch.
By the way I would like to add more options to kernel line.
Where can I find like a menu.lst file ? or How to add it to kernel line.
There is no /dev/graphics/* in running Debian console.
I would like to use FrameBuffer on running Debian.
thanks,

Android VNC won't connect Trying to get a handshake, but then says that VNC connection failed

You should understand that this is not a really booted native linux. Instead you are working in a chroot environment. So there is no kernel running that can get parameters. Only the the stock kernel of your DeFroST. Also there is no FrameBuffer as the graphic hardware ist not accessible. Instead this approach uses a vnc-server to which you can connect via a local viewer.
The advantage of this approach is clear:
- run almost any linux package available in the debian repository
- use your phone as before with the nice android
The disadvantage:
- no graphic output, so no 3D-games (which are rare under linux on the arm platform ;-)
- you can crash your android by eating up to much ram (not such a problem - it restarts on its own and if not you just have to reboot)

Thread is dead?
It seems this thread is dead. The problems many users seem to have come from a dirty setup. The image is broken in many terms:
- wrong file permissions on important binaries, like su
- wrong file permissions on many device files under /dev, so the ttys are only accessible by root
- wrong permissions on other places so there are always errors when installing additonal software (e.g. with the man pages)
- wrong setup that uses the root user for the desktop - instead an unprivileged user should be used
- missing packages for timezones and locales so the time is only right, if you are in a UTC region and console programs having trouble displaying anything else then plain english
I can not recommend using this setup image. It is better to use one of the instructions available online to get a clean setup.

Su doesn't work because your allready root.
Getting anything but root to work would be a real pain.
As you said its a chroot environment, its never going to be perfect.
The image was made using debootstrap just like all the other 'clean' ones.
Yep, it is broken as hell, but it works for what most people would need it for...make,gcc,python,a proper web browser,torrents, and some emergency word processing on the train to work.
The problem most people have is not being able to mount the image, this is due to fro-yo a2sd taking up all the loop devices.

Just thought I'd add my 2 cents.
I tried this on a MIUI rom and the scripy didnt do anything - ie i ran it using:
"# sh /sdcard/deboot"
.....and all it said was:
"#"
I entered all the lines in the shell script but the last one said it failed to launch VLC and no commands registered property (not even ls)
So i tried it on Defrost 5.1, and the script still didn't work.
But when i entered everything manually, it did work. Not too sure about the green theme though.
But thanks alot! Saves me spending a few hours trying to coax a working debootstrap out of my computer.
Thanks!
Josh.

Nope. Actually su works only for root. It's missing the setuid root flag like all other binaries that should have it set.

Nope. I am always working as a normal, unprivileged user in my chroot. You just have to be in the proper groups. No need to work as root. Android works also with an unprivileged user.

This is what I do not understand. There is no need that it is broken, as mine works without any errors. So I think something went wrong in creating yours. For sure a chroot is no running OS but you can server almost any service with it and run anything you want (if your ram does not get exhausted ;-).

Yes. Everyone with a good rom should have a2sd+ (aka the old a2sd) which saves more space than the froyo one and leaves your loop devices for you.

[Script] VERY simple application backup script for ROM upgrades [not for newbies]

Hi,
I'm new to the business and I spent some time to learn the environment trying different applications and different approaches for almos every action I took. Today, I have not much bigger knowledge, but I finally decided to take few things in my own hands because existing software is not fulfilling my wishes.
I started with this simple script which eases the pain of reinstalling all applications after ROM upgrade. There are few such tools already, but I found those quite bloated with unnecessary thing for my own approach.
With this script I assume:
1. There is/was SSHDroid installed (or any tool with busybox and you can access shell command line) both in old and new ROMs and your ROM have bash installed in /system/bin/.
2. Backup/restore operation includes only INTERNALLY installed applications, it completely ignores SYSTEM and SDCARD installed ones.
3. This is TEMPORARY backup so it should be as fast as possible not caring about occupied space (!). Althought I added -zip parameter to enable compression if you are running out of space on your sd.
4. Installed ROM is clean with no additional apps installed (excluding those needed by the script)
5. You have basic knowledge about bash scripting, because I take NO RESPONSIBILITY of the script behavior or data loss it can do.
So, basically it is simple. It runs like this:
1. On old ROM type: sbackup -backup
2. Flash your ROM
3. On new rom type: sbackup -restore
Just like that. The applications data is tar'ed in one file per application so if you want to get rid of any, just delete it from backup directory. The directory name is same as script name on sdcard but you can change it adding a parameter without a '-' sign at runtime (first non-option parameter is treated as backup directory path). The file is zipped because this forum disallows files without an extension so... it is zipped ;D
It was tested on my fresh LeeDroid 3.3.3 GB AFTER i installed some apps. I backed them up and then restored. All seems to be perfect right now, but I will test it more thoroghly very soon because I'm planninig to have CM7 based ROM too just to choose that I need Sense or not (two nandroids for fast switch weekly ;P).
With this script and MyBackup functionality of backing up contacts, sms, history and similar it should be quite complete approach to restore all the data needed on the fresh ROM. In the future maybe I will look at the MyBackup part too. Maybe.
Feel free to comment, use, suggest or anything you like, and have fun ;P.

How do I run this script? Do i run it from sdcard or from system /bin? When i do it from system bin it says cannot create directory. When i run it from sdcard/sbackup it says permissions denied?

And thats why I mentioned in topic about not being a newbie (and I meant not forum newbie but more a linux newbie). The thing is, it's a simple script - without any user-proof capabilities, comments inside or something BUT...
But ok, I will try to help you run it. First of all, you have to set permissions to the script. It has to have executable permission to be run by the system (and I mean filesystem permission). This can be done by chmod instruction of busybox. Most of the times it's done like this:
chmod 755 filename
This is a reason of not running form sdcard if your sdcard is NOT ext filesystem (it is usually windows fat filesystem not to generate problems with reading it under windows).
Second thing to run is to have /system/bin/bash because first line of the script (a comment like this: #!/system/bin/bash) instructs busybox to execute script using bash. This can be simply changed by modifying this line, but you have to remember that changing the shell executing script have consequences. Differens shells have sometimes different syntax, althoght i wrote this script simply so it should run on most of them, especially sh.
Third thing is to have write permissions to the directory in which the backup will be created. In original version of the script it is /sdcard, because backup is made in /sdcard/sbackup. So, you have to check it (second error - problems with creating directory).
And a last tip - it can be run from ANYWHERE. Even if your partition does not alolow executing, you can do it like this:
bash-3.2# /sdcard/test
bash: /sdcard/test: /system/bin/bash: bad interpreter: Permission denied
bash-3.2# . /sdcard/test
OK
bash-3.2#
First try does not succeded, but second did. The trick is a dot which means to execute file with a shell not caring about why or permissions.
And thats most simple introduction I could write. It applies to ANY script you want to run.
Please anyone - if you want me to help, paste your results here because without a precise error message it can be very hard to deduce what caused for example permission denial or anything usual.
For now, I won't add any more error handling, but if there will be more users caring about, I will add it.

[UPDATE 2/12/2010] Terminal IDE - Full 'on device' Java / Android IDE

[UPDATE]
BusyBox 1.19.2
Bash 4.2
Midnight Commander 4.8
TMUX 1.5 - That's right, full terminal multiplexer..
Vim 7.3
Terminal IDE ASCII Soft keyboard first round bug fixes complete.
It's the addition of TMUX and MC that really excites..
--------------------------
Well,
As the only people I know who might even be interested in this, I would like to announce the release of Terminal IDE v1.0.
A complete Java / Android Development Environment that runs on the device itself, with a nice telnetd / sshd feature.
For Android. Of course... Eat this you IPhone Hounds..
Woo HOO!!
The application is available on Android Market.
https://market.android.com/details?id=com.spartacusrex.spartacuside
As what I can only describe as 'dark days' finally draw to an end, I am very pleased with this first draft.
PLEASE give it a go, log in over telnet for a smoother ride, and let me know how it goes..
DO THE TUTORIAL! Does it work ?!
I have released the whole project GPLv2! Yeah, Who Knew!?
http://code.google.com/p/terminal-ide/
BOOOOOM!
Spartacus

a link to the app in the market would be usefull.

Interesting. Was just wondering about coding on my tablet.

Pretty freakin sweet
Thanks for putting this out!

Awesome
The full keyboard alone makes it worth downloading, but the IDE as well - wow!

this is best bro.

I randomly found this last night while looking for a decent mobile IDE for my tablet. I was looking for a simple text editor with syntax highlighting and you've taken that extra step to include other tools for ssh, telnet and compilers. Much appreciated.
One question, how do you start the ssh server? sshd doesn't seem to do it. I would like to scp files to my device from my desktop in order to work on my commute.
Thanks

The sshd app is actually called Dropbear.
You also have Dropbearkey.
You use Dropbearkey to generate the sshd certificates you need.
I really need to add a tutorial on setting the sshd keys up
For now Google has a couple of articles on it.
For file transfers you also have busybox FTP but I admit not terribley secure..
Allthough SSH is provided, and I wonder whether an SSH pipe can be created..?
And lastly you can just copy the files over to your sdcard via USB..
Will look into it & add tutorials asap.

Ok. So I now have SSHD working..
But there is a slight issue.. basically when you log in you have to start bash manually.. unless you have the file /etc/shell with the correct shell to use.. Which requires a rooted phone.
Since Terminal IDE is for non-ROOT users, I will have to recompile the code to allow a shell to be specified on the command line.. Soon..
FOR NOW - This is how to connect to the phone via SSH (There are other ways using public keys but this is one way)
So - Once in Terminal IDE
2) You need to create a couple of server ssh keys
Start in $HOME
Code:
cd ~
Create folder
Code:
mkdir .ssh
Give it some secure permissions
Code:
chmod 700 .ssh
Get in there
Code:
cd .ssh
Now create the keys
Code:
dropbearkey -t dss -f dropbear_dss_host_key
dropbearkey -t rsa -f dropbear_rsa_host_key
ok - That's almost it. Just need to start dropbear with the correct parameters now. [Probably want to keep this in a script]
Back HOME
Code:
cd ~
You need to know the UID of your app, which is different per phone - use 'id'
Code:
id
That will tell you your user ID / Group ID. Let's say its 10058.
Now to start DropBear
Code:
dropbear -A -N username -U 10058 -G 10058 -C password -d ~/.ssh/dropbear_dss_host_key -r ~/.ssh/dropbear_rsa_host_key -F -E -p 8090 -P PidFile
This will start it running in the foreground with password set to 'password' on port 8090.
Then you can connect, like telnet, and simply use 'password' for the password.
Now for the issue. It will start a simple shell session in / with no ENVIRONMENT variables or anything..
I'll fix it permanently in a future release, but for now it can be fixed with these 2 commands.
cd into your home dir - Check this is correct on your device
Code:
cd /data/data/com.spartacusrex.spartacuside/files
And start bash with an init file Terminal IDE auto-magically creates..
Code:
./system/bin/bash --init-file ./.init
Everything should now be setup as usual.
Good luck..

Very awesome and thank you sir. Works like a charm.
One thing to clarify for those "braving" this (not that it's all that insane to try)... the '-N' is setting the username (in the case of the example, setting it to 'username').
Also, it gives a permission denied for scp, I'm assuming since it doesn't init/run the shell. Should be fine since FTP is included. Haven't tried this option yet. Not too worried about security at the moment, since I'll only run it on a private network.
May I make a (maybe) small feature request? Is it possible to include a "keep screen awake" option in the options menu? I have my Xoom config'd to turn off the wifi when the screen is off for power saving (can go ~4 days on 1 charge), so it will kill my connections if I let this happen. I know not everyone has this config set, but it'd be a nice option.
NOW, if I wasn't lazy, I could probably add this myself and build since I've dl'd the source. But, lazy and working on a few projects already.
Again, much thanks.

And as if by magic..
Funnily enough I was having the exact same issue last night while using wget to transfer a big file to my device..
NEW VERSION UPLOADED v1.13
Now has 3 non-exclusive lock types available in the options :
- CPU Lock
- SCREEN Lock
- WIFI Lock
Set them as you wish...

Saw that this morning when I was on the bus (Thursday morning here in Hong Kong). Very awesome and much appreciated.
As well, thanks for open-sourcing it. +1 for you sir!

Very cool stuff
Thanks for creating this.

Great app! However I can't compile .java files. I always get an error that it can't unzip a file in /android.policy.jar. Any idea?

Do you think its possible to also support compiling C sources directly in your phone

I've been searching for this ever since I got an android.
THANK YOU.

Says that it's incompatible with my OG Droid. Any idea why?

Most likely seems to be due to the ROM you are using and/or the market version
can u post the build.prop here?
/system/build.prop
also, try going back to market 2.x, 3.x market(s) do loads of checks

Does anybody know why I can't compile java files? I always get the following error:
Error reading /system/framework/android_policy.jar cannot read zip file.
Any ideas? Could anyone upload there android_policy.jar because that might cause the error.

Hi Schindler33.
Can I ask, have you followed the tutorials, say the first helloworld example TO THE LETTER?
Does the helloworld example work?
The parameters have to be correct, and as always exact, and the BOOTCLASSPATH variable must be set.
If so, is it a custom ROM?
Does that policy jar file exist and is it readable by non root users?
As much info as possible good..

Ubuntu Woes on Urukdroid

Following the instructions here, I attempted to install Ubuntu 10.10 on my Archos 70 running Urukdroid 1.5. I'm running it through the terminal emulator and not ADB. When I attempt to run ubuntu.sh I get a lot of errors, and then bootubuntu fails to work.
sh output:
Code:
mount: /system not mounted already, or bad option
FATAL: module ext2 not found.
TERM environment variable not set.
mkdir: cannot create directory '/data/local/mnt': File exists
TERM environment variable not set.
rm: invalid option -- '/'
Try 'rm --help' for more information.
cd: 26: can't cd to /sdcard/ubuntu
chmod: changing permissions of 'bootubuntu': Operation not permitted
(errors for all the other chmods as well)
TERM environment variable not set.
(Ubuntu Chroot Bootloader v0.1, etc.)
And naturally bootubuntu generates a big pile of errors as well. Any suggestions?

There are 3 leethal messages:
I'm not sure about the ext2 message - can't imagine that UD has no ext2 module - need to check it out myself...
"TERM environment variable not set." is obvious - means there is some (TERM) environment variable missing wich is propably set when use adb?!?!
As the variable is used in each command after the error - they fail ... so the folders that should be created or removed propably have the variable in its structure and should sound a bit different...
hard to tell from here need the script - downloading atm - but takes ages
cd: 26: can't cd to /sdcard/ubuntu sounds a bit strange too but again it seems that u can acces sdcar with /sdcard from adb but on UD runtime its mounted /mnt/storage/sdcard...
So either you try to fix those lines in the scriptand find it out - or try follow they guide - and use adb

Well, I decided to redownload the Ubuntu image and try again. This time it went off without a hitch; I guess I had some file corruption in the first download. But now I've done the essential steps (apt-get updates, setting up LXDE environment and VNC server) and when I try to connect to the VNC host I just get a gray screen with an "x" shaped cursor and nothing else.

Same here. X-Server seems to start (grey background, x-shaped cursor), but nothing else. Tried the 2 versions of the xstartup (with, and without the last 2 lines), no change. I had to increase the portnumber with every reboot (working with pocketcloud to connect to the vnc server).

hi guys, this seems to be a problem some people are having with the new 10.10 build, the problem is I cant seem to replicate the problem.
I would recommend trying a fresh ubuntu image without install lxde or the fixes, ie just boot into vncserver.
If this dosnt work then try installing lxde and adding the lines to the xstartup to makesure it uses that desktop.
Thanks

I'm having (unrelated, probably) problems running this on the stock ROM with Chulri's r/w root. I am unable to mount the provided image (or any loopback filesystem, for that matter), whether from the script, or manually from a root shell prompt.
It appears that the stock kernel does not include a loop device driver (built-in, or as module), as there's no 'loop' directory under /sys/module/ and no loop.ko under /lib/modules. The installed busybox is also lacking losetup and chroot, but that's almost beside the point.
To deal with this, I've built a fixed busybox, which works fine, and a custom kernel using Chulri's buildroot, which doesn't, so much. I've built custom kernels for the Archos 70 before, to add compcache and the interactive CPU governor, and they've worked fine. But in this case, I make sure CONFIG_BLK_DEV_LOOP is set to 'y' in linux.config/.config, but after flashing the kernel and rebooting, there still seems to be no loop driver (no loop directory under /sys/module -- it should show up even when compiled-in, which it does on my Fedora desktop). Needless to say, this confuses me, and it's where I stopped working on it.
Has anyone got this working on a Gen8 Archos tablet without Urukdroid?

It would seem that loop devices only works well on the Urukdroid rom, so for now if you want ubuntu you will have to use this

[B928] OC kernel 0.1 [one-hit wonder]

This will not be worked on any longer thanks to Huawei's incompetence. I'm glad my main phone isn't by them. I leave my 0.2 diff attached (which did make my phone faster FWIW - and has fsync() control. Not of use to me, but people who use a modified libsqlite would like it...). Feel free to apply it and see if you can somehow fix dhd.ko loading.
Hi,
Not one for names, so this shall be known as "OC kernel" This is built from the ICS U8800pro source that Huawei put out.
Install at your own risk; I take no responsibilty for any damage that may occur through the usage of this kernel.
Features:
ADB as root
Overclocking enabled (thanks to genokolar)
Undervolting interface added (from genokolar, who took it from a SE kernel modder somewhere) - I think SetXperia can use it
SIO I/O scheduler added
SmartassV2 cpufreq scheduler (AnDyX mod) - although I think ondemand does a bit better IMO
sysfs entry to turn off keypad lights (I wrote an applet for this some time back, I'll dig it out later)
Logcat is always enabled now as the ServiceMenu toggle doesn't work anymore
Minimum display backlight is set to 15, but I think Android needs a framework change to use it. You could try RootDim
Kernel actually builds (and Bluetooth works)
ZRAM (+ swap) support. ZRAM is optimized for Android (taken from Siyah kernel). I'll write up the instructions on enabling this later
CIFS as module
Extras:
Change schedulers and phone speed:
Use a tool like No Frills CPU or SetCPU.
Turn off button lights:
Install the ButtonLight widget and add it to your main screen. I've published the source before in another thread; seek it out if you're after its (bad) code.
It's buggy the first few times you run it, but works fine after that.
Dim screen to 14:
The minimum backlight level is now set to 15. RootDim from the Play Store lets you set it to that.
Mount Windows shares:
Grab CifsMounter and point it to the cifs.ko in /system/lib/modules. You may also need to insmod nls_utf8.ko and md4.ko.
Enable ZRAM (taken from Siyah kernel):
(Note I've not used ZRAM so I have nothing to say on its stability, good or bad)
Grab a BusyBox binary from somewhere
Run the following commands:
Code:
echo 90 > /proc/sys/vm/swappiness #You must set the swappiness high to ensure that the compressed RAM is accessed first!
echo $SIZE > /sys/devices/virtual/block/zram0/disksize #Set size to whatever you wish. 100MB is 104857600 = 100 * 1024 * 1024
busybox mkswap /dev/block/zram0
busybox swapon /dev/block/zram0
Dump the lines in install-recovery.sh if you want to be ZRAMMed every time you boot the phone (although in that case, make sure you have
Code:
busybox swapoff /dev/block/zram0 > /dev/null 2>&1 #Use > /dev/null 2>&1 for every busybox command in install-recovery.sh as it will discard any messages outputted
echo 1 > /sys/devices/virtual/block/zram0/reset
before the lines above)
Install:
Flash the attached ZIP in CWM recovery. You should backup your original boot.img and /system/lib/modules first

'cause I add a new module - cifs (used by CifsMounter if you want to mount Windows shares) - and because the modules that are originally in /system/lib/modules need to be replaced so that they can load with this kernel (I don't know what those modules do, but I'd rather play it safe)

Regarding FPS: do the install-recovery.sh trick
Only thing I modify in initramfs is the ro.secure setting so that ADB can be ran as root

Unfortunately I won't be working on this anymore unless Huawei get back to my request for the source to the the dhd.ko module (which they may not have to comply with because the license for the module states "Unless you and Broadcom execute a separate written software license agreement governing use of this software" so the U8800pro version may not be under GPL). I made (well, found on the Internet) more optimizations but the Wi-Fi refuses to turn on because the dhd.ko module refuses to load. Only way I can get something working is to build the source that Huawei give or attempt to force other versions of the bcm source to load, but it's unlikely that would work.
--
Anyway, a small guide.
I used an x86_64 laptop running (X)ubuntu 12.04.1 to follow these steps. This page was a great resource.
Prerequisites:
A computer running GNU/Linux (a Mac should work in theory - the same toolchain we use is built for it, too, but I have no idea how OS X works)
git installed (apt-get install --no-install-recommends git-core is enough under Ubuntu)
sudo apt-get install flex bison gperf build-essential libncurses5-dev zlib1g-dev ia32-libs lib32z1-dev lib32ncurses5-dev gcc-multilib g++-multilib abootimg
Getting ADB working
One of the best things to do is getting ADB set up, as you then have easy communication with the device. It's not essential but you'll just end up wasting time transferring files through other, longer means.
Grab the Linux platform tools ZIP from here: http://www.hariadi.org/android/manually-download-of-android-sdk-tools-and-sdk-platform-tools/. Extract the adb binary from the zip file, preferably to somewhere in your $PATH. chmod 755 it. chown, if necessary.
Next, open http://aur.archlinux.org/packages/an/android-udev/android-udev.tar.gz and, doing all this as root (sudo in Terminal etc.), place 51-android.rules in /lib/udev/rules.d/ (not the best place - but it works), chmod 644 it and chown root:root it.
Next, execute /usr/sbin/groupadd adbusers, followed by gpasswd -a USERNAME adbusers, USERNAME being the user you normally log on with.
Restart (while you can force Linux to see the new group through the, well, newgrp command udev will not "see" the new rule, despite how much you try with udevadm).
That should be ADB set up (give it a test, remembering to enable USB debugging mode on the phone first!).
On to preparing your workarea.
--
Create a new folder in your home folder and cd to it. This folder will house the prebuilt folder of toolchains and other stuff, and the kernel source in a folder of its own.
In this folder, execute git clone --depth 1 https://android.googlesource.com/platform/prebuilt.git and move onto the next step, since the download takes a while. That command grabs the prebuilt toolchain from Google using Git, but doesn't obtain a deep history for each file to make the download quicker.
Open http://www.huaweidevice.com/worldwi...=toDownloadFile&flay=software&softid=NDY3NTU= and save the source to your Downloads directory. After git has finished running, still in the folder with the "prebuilt" folder, execute tar jxf ~/Downloads/HUAWEI_U8800pro<tab - as in actually press tab> and you should have a kernel folder alongside the prebuilt one.
Building the kernel
cd to this new kernel folder.
First things first: make sure that Bluetooth is properly enabled by editing the Makefile. Find the line #ifeq ($(ENABLE_BTLA_VER30),true) and comment out every line in that section except for KBUILD_CFLAGS += -DHUAWEI_BT_BTLA_VER30 so you end up with this:
Code:
#/* < DTS2012020604357 zhangyun 20120206 begin */
# Add Huawei Marco for different BT chip
#ifeq ($(ENABLE_BTLA_VER30),true)
KBUILD_CFLAGS += -DHUAWEI_BT_BTLA_VER30
#endif
#ifeq ($(ENABLE_BLUEZ_VER30),true)
#KBUILD_CFLAGS += -DHUAWEI_BT_BLUEZ_VER30
#endif
#/* DTS2012020604357 zhangyun 20120206 end > */
Commenting out the offending code leaves you with a kernel that builds but a Bluetooth module that won't start up - the same also applies if you try to build with the other define.
You can also make things easier for yourself by replacing the following
Code:
ARCH ?= $(SUBARCH)
CROSS_COMPILE ?= $(CONFIG_CROSS_COMPILE:"%"=%)
with
Code:
ARCH ?= arm
CROSS_COMPILE ?= ../prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-
else you will have to put "ARCH=arm CROSS_COMPILE=../prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-" after "make" each time. Remember this as I'll be assuming that you went for the option to edit the Makefile. I also assume that the prebuilt folder is above the kernel one. Adjust CROSS_COMPILE if necessary.
The ARCH variable is self-explanatory, but the CROSS_COMPILE variable (and the toolchain that it's pointing to) need to be set because the standard GNU development tools that apt installs don't produce output that an ARM processor can understand. So you cross-compile: the tools are for the X86 architecture but produce ARM output. 4.4.3 is chosen because the stock kernel is compiled with GCC 4.4.3 (if you run "adb shell cat /proc/version" you'll see). The arm-eabi-4.4.3 folder is chosen over arm-linux-androideabi-4.4.x because it specifies that magic "3" (I know, bad way to decide but it works), and over i686-android-linux-4.4.3 because we don't want to produce code for the PC.
Get the current configuration in use by the stock kernel (as that's a good point to start from - a known working configuration): http://wiki.cyanogenmod.com/wiki/Building_Kernel_from_source#Configure_the_Build
I'd also recommend placing a copy of .config as arch/arm/configs/<your funky name here> so that if .config gets deleted (make clean etc.) you can run make <the name you gave to the file in arch/arm/configs> and have .config come back again.
(cp arch/arm/configs/<the name you gave to the file> .config if you didn't modify the Makefile to specify the ARM arch.)
Run make oldconfig (not always necessary - generally it's invoked if you've applied a patch that introduces a new config option and the option then needs to go into your .config. Run make menuconfig afterwards and customize away.
When you're done, run make -jX - X as in the number of cores you have + 1. So, in my case, with a quad-core processor and HyperThreading enabled on all of them, "make -j9" works for me. If the compile went OK, you'll be left with a message saying that arch/arm/boot/zImage is ready. If not, run "make" without the -jX argument and make should stop where the error occurs. Have fun fixing the error!
Assuming that you have a new, shiny zImage, it's now time to put it into your boot.img.
Updating your boot.img:
Google have tools for this purpose but I've never used them so I don't know how they work. abootimg works fine for this, however.
Pull the current boot.img off your phone: adb pull /.cust_backup/image/boot.img.. I'd recommend creating a backup somewhere.
Create a new directory to store the boot.img in on your computer and run abootimg -x boot.img (if you had fun enabling every option in the kernel, you'll see why I'm telling you to use the -x option first rather than directly use the -u option). Now run abootimg -u boot.img -k <path to your newly built zImage>.
If this succeeds, yay! If not and you're told it's too big for the boot image, then don't worry. Take the size it's saying that the zImage is and convert that number into hex. Edit bootimg.cfg and change the value of the bootsize setting into the number you just converted into hex. We'll now repack again, but this time running abootimg -u boot.img -f bootimg.cfg -k <path to your newly built zImage>. This should work.
Sending the boot.img to the phone
If your ADB is already running as root, you can do the following to upload the new bootimg:
Code:
adb shell mount -o remount,rw /.cust_backup
adb push boot.img /.cust_backup/image/
adb reboot
If not, just reboot into pink screen mode and copy and paste.
Check System Settings and the version number should've changed. Congratulations!
Extras
Installing the modules:
OK, so you decided to build parts of the kernel as a module and you want to actually, y'know, have the modules present on the device. After building the kernel, execute:
make INSTALL_MOD_STRIP=1 modules_install INSTALL_MOD_PATH=<any folder name here>
If you look in that folder, you'll find the modules neatly wrapped up in folders, along with other text files. These text files are useless on a stock ROM because there's no modprobe - you need BusyBox for that. And since we don't want to have them seperated in folders (this is how the stock kernel does it), the files would be wrong, anyway. If you want to use modprobe and have BusyBox installed, you can run depmod on the phone after transferring the modules.
To get the modules into one folder make the directory "modules" in a folder higher-up to where the modules are stored, and then run for i in `find . | grep ko`; do mv "$i" ../modules/; done to move them into that folder.
At this point, I'd just recommend using my OC_Kernel.zip and replacing the modules in that. Or you can adb push them over to the /system/lib/modules folder (after issuing an "adb remount" - assuming that ADB is running as root in the first place).
Making ADB run as root:
As root on your computer, (we want to preserve permissions) use abootimg to split the boot image and extract the contents of the initrd:
abootimg -x boot.img && mkdir newramdisk && cd newramdisk && zcat ../initrd.img | cpio -i --no-absolute-filenames (--no-absolute-filenames is important! I trashed a Ubuntu install by leaving it out - the initrd contains ARM binaries of core Linux programs and if the initrd.img contains an absolute path of "/" then these files will get placed in /)
Make any changes you desire to the initrd. To have adb run as root, just edit /default.prop and set ro.secure to 0. Make sure that the editor you used didn't leave any backup files.
When you're done, run find . -print | cpio -o -H newc | gzip -n -9 > ../initrd.img and this will put the modified initrd folder back into initrd.img.
After that run cd .. ; abootimg -u boot.img -r initrd.img to actually put the initrd.img back into the boot.img.
If you run into a space error, you can do one of three things:
if you only made a single change (like enabling ADB), check to see that there is no backup file (default.prop~) littered about
you can remove the lengthy comments and copyright notices from the files to make space
you can use the trick we used earlier with abootimg to increase the size number in bootimg.cfg for the initrd
Overclocking:
Just look at the acpuclock C file (and possibly relevant cpufreq changes - but I can't remember) in my "OC kernel" diff. Make sure that the option in the kernel config is selected to limit the speeds to the U8800pro's native 1GHz, otherwise the phone will boot at 2GHz!
Rebuilding the Wi-Fi module:
I hope to be able to write this one since it's apparently needed in some cases, but it depends on if Huawei come through

Honestly, I have no idea. What toolchain are you using and where was your .config obtained from? Even when the Bluetooth thing was giving me errors, I never once saw that

same toolchain you have used. i have tried with ubuntu 12.04 x64 and ubuntu 10.04 x86 but same problem.....i have obtained my config from my phone using adb command

Done, check the first post
I also won't be working on this. My email (which does clearly state what I want, even if it's long-winded):
Dear Sir/Madam,
I recently built a kernel for my U8800pro from your sources and it
works fine, except that the Wi-Fi will not start because the dhd.ko
module that comes with the B928 firmware refuses to load into my
modified kernel. After looking around, the bcm4329 source is what I
need to build (usually distributed outside of the kernel); however, it
seems that the U8800pro uses a customized version. After looking at
the strings of the dhd.ko on the B928 firmware, I have seen many
strings that are present in that dhd.ko binary do not appear in:
* bcm_4.218.248.6_7x25_wifi_driver.tar from the Huawei Device website,
despite it having the same version number
* the bcm4329 source in the Qualcomm CodeAurora Git repository
* the bcm4329 source on the NyVIDIA Tegra Git repository
Furthermore, the strings also do not appear in the ICS kernel nor the
Gingerbread one. I can only conclude that Huawei have their own
specialized version of the bcm4329 4.218.248.6 source for the U8800pro
that is distributed outside the kernel. I understand that Qualcomm
allow the option to let the vendor arrange to have the code
distributed under a different license provided that the vendor makes
an agreement beforehand with Qualcomm. Otherwise it becomes GPLed by
default. If Huawei chose to make an agreement, then I have no right to
ask. However, I believe it is still licensed under the GPL for two
reasons:
* Running modinfo on the dhd.ko from the B928 firmware says this:
"license: GPL v2
* Both bcm_4.218.248.6_7x25_wifi_driver.tar.gz and
[S7][SoftWare]S7_Broadcom_BCM4329_4.218.205.0_Open_Source are under
the GPL
I would like to request the source code, please, of the bcm4329
4.218.248.6 source that is modified for the U8800pro if the code is
under the GPL
Best regards

Since my U8800pro is not my main phone anymore, I do not have the energy to fight. Nor do I want to work on Huawei's kernel, where you have to be careful about what you change or the Wi-Fi module won't load (and Huawei won't give you the source - which they should do since I'm sure it's under GPL). matteof93 will most likely produce something better or when everyone starts producing their own kernels and make enough improvements to be hit with the same issue as I, they'll start to get more emails and listen

@qwerty at the last command it said that device is busy...also is there any way that you can make it for init.d so it will be easier??thx!!
