Development thread for Linux on the HTC HD2
PLEASE READ THE FAQ BEFORE POSTING QUESTIONS
Introduction:
To run any Linux based user space on a device -this includes android, debian, ubuntu, openembedded, etc- you need a working Linux kernel.
This thread discusses the development on Linux kernel and user space on the HTC HD2.
All android ports to windows phones are based on the efforts of porting the Linux kernel to these devices. This is what all the porting is about. Nobody is porting Google Android to these phones. It works already.
Contributing:
This is not a secret club. All source code and development information is publicly available. Everybody who is willing to contribute is free to join the development process.
People working on porting Linux to HD2:
You can donate to the developers putting a lot of time into this Linux kernel port.
(putting together android files (=>making "roms") is not the porting)

working flashlight
ppp stability
usb stability (works with windows7 now)
fixed usb host mode kernel
working backlight control in normal Linux distros
working WiFi master (access point) mode: enables tethering (you might need to update firmware files. )
09/05/2010 We have been working on a new kernel base for the HD2 for few days now. Markinus started the initiative by introducing our present HD2 specific changes in the EVO4G release kernel source code. Right now the htc-msm-2.6.32 branch is still more advanced. We might create an autobuild for the EVO4G base kernel in case it will be superior at some point.
Builds
Global notes:
*None of the current releases will touch your internal flash. After restart you are back in the usual winmo.
*When Linux is booted, windoes mobile is shutdown abruptly. Although this is very rare it can cause some data loss. Please save your work and make frequent backups!
*You need at least a 2.08 radio rom version installed on your HD2. If yu have an older version you might not be able to boot Linux.

Click here to view autobuild history (archived dated zImages and modules)
Most recent zImage (Linux kernel image)
zImage-htcleo-latest
The Linux kernel is the core element of your operating system. It contains most of the drivers. It is supplied in form of a compressed (gzipped) executable binary Image. Along with an initial rootfilesystem aka initrd it is loaded into memory and executed by the bootlaoder HaRET.
Most recent Linux kernel modules to match zImage-htcleo-latest (has bcm4329.ko)
modules-htcleo-latest.tgz
Kernel modules are drivers that are not included in the zImage. They go seperately in .ko files. bcm4329.ko holds the wifi driver and tun.ko is needed for tunneling. For android use you must extract the modules.tgz file, search for the .ko files you need and copy them into /system/lib/modules/ directory. See FAQ for how to copy files into your android install.
HaRET (bootloader)
HaRET.exe
The haret bootloader is used to start Linux according to the instructions it reads from the file default.txt . If HaRET sees a file called startup.txt it will use this instead and boot Linux directly without any prompt.
startup.txt (bootloader/HaRET configuration - auto updated to match latest GIT kernel)
startup.txt
NOTE: This example configuration only holds the parameters critical to booting with latest GIT. Ask the person supplying you with 'roms' for additional parameters needed. See FAQ section for more detail on parameters.
Android
Please browse the main HD2 Android forum for various recent builds.
It is always important to install a recent kernel. See post #3 for how to.

INSTALLING NEW LINUX KERNEL (zImage) AND MODULES (.ko files)
Three Things to know about the Linux kernel
1) The Linux kernel is the center of your of your operating system. Its core is seated in the kernel image (zImage file - the z means it is compressed). It contains most of the drivers.
2) Some drivers go external via Linux kernel modules (.ko files). E.g. in the HTC HD2 Linux kernel, the WiFi module is supplied as bcm4329.ko
3) The kernel image and kernel modules are made to match. They need to have the exact same version. This means if you pick a random .ko file things might go wrong => Find always up to date kernel image and matching modules here
Editing startup.txt
1) The following lines are needed in startup.txt to make GIT kernels work in any build !
set mtype 2524
set ramaddr 0x11800000
set ramsize 0x1E400000
set initrd_offset 0x00a00000
set kernel zImage
<ADDITIONAL PARAMTERS GO HERE!!!!!!!!1 Remove this line.>

Click to collapse
2)Additionally you need to specify the following. Those parameters are dependent on the build you use. Look them up in your present startup.txt
*Initial ram disk filename (set initrd initrd.gz)
*Command line paramters (set cmdline "foo=bar google=android" )

Installing the latest Linux kernel image (zImage)
1) Download the latest Linux kernel image (right click, save file as)
1a)for Google Android
1b) for classical GNU/Linux based distros (Ubuntu, openemebdded, meego, maemo etc)
Be aware these build links are dynamic and will be updated once the Linux kernel source code is updated. See here for static links
2) Rename the file to zImage
3) Overwrite your old zImage file with the newly obtained zImage file

Click to collapse
Installing the matching Linux kernel modules (.ko files)
1) Download the latest Linux kernel modules to match your kernel image
1a) for classical GNU/Linux based distros (Ubuntu...)
1b) for Google Android
2) Install the modules...
2a) in GNU/Linux
As root run
cd /
tar xvf /path/to/modules-htcleo-usbhost-latest.tgz
Click to expand...
Click to collapse
2b) For Google Android...
extract the modules-htcleo-latest.tgz file
you will notice it contains a directory structure.
example for module locations within modules-htcleo-latest.tgz :
WiFI module:
lib/modules/2.6.32.9-38151-g827fa85/kernel/drivers/net/wireless/bcm4329_204/bcm4329.ko
Network tunneling module:
lib/modules/2.6.32.9-38151-g827fa85/kernel/drivers/net/tun.ko
Yet Another Flash Filesystem module:
lib/modules/2.6.32.9-38151-g827fa85/kernel/fs/yaffs2/yaffs.ko
Basically you want to copy all .ko files you need into /system/lib/modules directory
Learn 3 Methods to do so detailed in the following:
memin1857 said:
Three different methods for replacing bcm4329.ko (which makes wifi work) Method B seems to be the best.
Easiest: (uses winmo, does not use third party app or commands)
A) (MAY ONLY WORK FOR SHUBCRAFT BUILD) Under winmo, create a folder named root inside your Android folder in your sdcard. This folder named root will be the actual root when Android boots up.
For example:
Create this folder structure under winmo:
STORAGE CARD\Android\root\system\lib\modules
and copy the bcm4329.ko file in it. It will look like this:
STORAGE CARD\Android\root\system\lib\modules\bcm4329.ko
Boot Android and the file gets copied to the protected Android file system. (/system/lib/modules)
If you do this from within Android, reboot to take effect.
B) Start a Terminal Emulator within Android. (Install a terminal emulator from market if not already installed) Copy bcm4329.ko to sdcard root beforehand. Filename has to be all lowercase. Enter these commands:
su
mount -o rw,remount /system
cp /sdcard/bcm4329.ko /system/lib/modules
you should get no response and wifi should work immediately.
you may want to make system readonly again with command
mount -o remount r /system
Delete old bcm4329.ko file if it exists at /sdcard/Android/root/system/lib/modules or it will come back on next reboot.
C) Use a third party app like Root Explorer, Droid Explorer, Root Manager, ES File Explorer and copy the bcm4239.ko file to /system/lib/modules which is mounted in read-write (RW) mode.
(DROID EXPLORER RUNS FROM WINDOWS XP/VISTA/7 and uses adb. No reboot required. Others run from within Android)
You can do A, B OR C. You don't need to do them all. Method A had only been tested in shubcraft v1.2b build.
As a fourth way you can use adb command that comes with android sdk. install usb drivers from within android sdk and connect your hd2 with usb debugging enabled. commands are same with terminal just put adb in front of it and run from folder adb is in.
If you copy an incorrect version of bcm4329.ko that is not matched to your zImage kernel wifi will say error and not work.
You can also WAIT for a new build that properly includes these files already to come out.
You can get bcm4329.ko file from http://oe.netripper.com/files/htcleo_autobuild/modules-htcleo-latest.tgz
Open the tgz file with winrar or similar program. The bcm4329.ko file is under lib\modules\2.32.xxxx\kernel\drivers\net\wireless\bcmxxx

GENERAL FAQ
*Some Roms are reported to work better with Android than other Roms. Duttys Roms seem to have the robot voice problem on calls. Miri's WM6.5 v17 Roms and NRGz Energy Roms seem to work best and have fewer problems.
* With some old radio rom versions it is impossible to boot Linux. Make sure you install a 2.08 + Radio. known working Radios are 2.10.50.08_2 and 2.12.50.02_2
* With the working Linux kernel any kind of Linux based userspace can be used on hd2. This includes google android and any other Linux distribution.
* This is a work in progress! Lots of stuff is still missing. Check http://htc-linux.org/wiki/index.php?title=Leo/Status for current state of affairs
* We know about most available sources of Linux kernel code for the snapdragon devices. It is not necessary to point to evo, bravo, nexus etc.
ANDROID TIPS AND HELP
No Sound in Android: Make sure you run clrad.exe BEFORE running the haret.exe file to boot Android. When you run it, it will not do anything but it does run.
Mobile Internet isnt working on TMOUS HD2: T-Mous users have to manually enter the APN for the mobile internet to work. Go into Network, Mobile Networks, APN. If the APN screen is blank press the Windows button and choose "Add APN" from the menu that pops up. Enter the following, Name: epc.tmobile.com, APN: epc.tmobile.com. Leave the rest blank. Then press with Windows button again and save. Your mobile internet will now work.
Setting up APN (Access Point Name) for Wireless Internet (other than TMOUS): Get your settings from *HERE* then on Android goto Settings, Wireless & Networks, Mobile Networks, Access Point Names. If bank press the Windows Button, New APN and enter your details.
For those having issues with WiFi turning on and off: Go to Settings>Wireless and Networks>Wi-Fi settings>Advanced(Windows key)>WiFi sleep policy> Select Never
Green Screen when booting into Android: Pull out and reinsert the battery, restart the phone and try again.
Phone gets stuck when loading Android (progresses very slow or stuck in the same postion for several minutes): Pull out and reinsert the battery. Delete all references to Android from your storage card including the cache folders and any folders Android created. Then copy the downloaded files back to the ROOT of your storage card or where you are supposed to place them (including the AndroidApps and media folders if you have them). Soft reset your device and run the clrad and haret files within 30 seconds of WinMo loading or use a program such as JMZ's Bootloader.
Sleep of Death (not coming out of sleep): Update your Linux kernel image and modules as instructed above, then restart your phone and restart Android. If you keep getting Sleep of Death with the newest Linux kernel image and Linux kernel modules files then reformat your storage card with FAT32 and start over again. Always make sure you run the latest Linux kernel image and modules.
How to install .apk files on Android: Copy the .apk file to your storage card that you want to install. (see kernel guide for android file copying howto) Load Android and run 'Linda File Manager' from the programs list, then browse to 'SD Card' (complete action using Linda File Manager if asked) and then to the folder where you put the .apk file. Note: To see more information on the screen minimise the keyboard, then click 'view' and select 'details'. Once you have found your .apk file click on it then tick 'Use by default for this action' and select 'package installer'. Now just follow the onscreen instructions to install your program. OR you can copy the .apk files to the AndroidApps folder in the ROOT of your Storage Card and they should auto install when Android loads (most of the time).
Battery isn’t charging in Android: Install the latest Linux kernel image and Linux kernel modules as detailed above.
Excessive Power Consumption: Remember that all these builds are still in beta version and not complete. Alot of things are still being ironed out.
Programs and system functions not working (such as Video camera, Bluetooth, Keyboard backlight on sleep, etc): Install the latest Linux kernel image and Linux kernel modules as detailed above.
No Ringtones or Notifications in setup (in DarkStone's Builds): Download the following file http://gamesquare.co.uk/media.zip (copy the link into your browsers address bar or it wont download). Extract the 'media' folder (make sure the folder has sub folders with the sounds inside those) to the root of your SD card. Now go to Settings, Sound and Display, Phone Ringtone or Notification Sound and they should be there.
What is a zImage? zImage is a Linux kernel binary image. It is the core of your operating system containing most of the drivers. The prepended z means that it is compressed with the gzip algorithm, making it smaller than the non compressed Image file.
Can I use more multiple zImage files at the same time? No. Your phone can only execute one Linux kernel at a time. HaRET.exe (the bootloader) reads the kernel filename from startup.txt - You can maintain multiple zImage files on your phone but chose only one via startup.txt
How do I change the background wallpaper? Hold your finger on the screen and select Wallapers from the popup list.
How do I change the settings? Press the Start Menu button on your phone (middle hardware button) to bring up the menu, then select the bottom middle button (settings or preferences depending on your Android build).
I cant update an app thats pre-installed (i.e. facebook or twitter): Download Root Explorer from the Market, then open it and browse to the 'system, app' folder. Delete the apk file of the app you want to update then try downloading and installing it again.
If you are trying out a TEST build of Android then you SHOULD have a basic level of intelligence (laughs quietly to self) so PLEASE use your brain and try to work things out for yourself before posting a question.

USEFUL ANDROID INFORMATION
1. The difference between Desire Builds and Froyo Builds (thanks to memin1857)
Desire build is ripped from an HTC Desire. It is Android version 2.1 (Eclair)
Froyo build is ripped from a Nexus One. It is Android version 2.2 (Froyo)
Froyo is a newer and much faster Android version. It is currently only available on Nexus one officially. Other newer phones will get it eventually.
HTC Sense is the user interface on top of Android. Desire builds have it already. It can be disabled for standard Android interface.
2. Importing WM Contacts into Android (thanks to brownman)
You need PIM Backup, a computer with internet access and a Gmail account.
1. Open PIM Backup on your Windows Mobile device. Select the Backup action and unselect everything but contacts, then hit Next.
2. At the "Select backup filename and folder" screen, unselect the "compress backup" and "binary backup" options, then hit Next.
3. Transfer the BACKUP.PIB file that you just made from your phone to your computer. Change the extension from .PIB to .RAR, then extract the file.
4. The extracted file should be BACKUP.CSC. Simply change the extension to .CSV and import the file to your gmail account. All your contacts can now be imported to your phone through gmail - just follow the instructions given in the phone's contact menu.
or activesync with google http://www.google.com/support/mobile/bin/answer.py?hl=en&answer=138636
3. Putting a Shortcut button on HTC Sense, etc to start Linux (in order to boot Android, Ubuntu, etc)
1. Make sure you have your Android build copied to your Storage Card as instructed earlier in this FAQ
2. Install mskip's Android Loader from *HERE* and install to DEVICE Memory
3. Add a Shortcut Button to your Sense, Mobile Shell or other Today Screen Plugin
4. Click on the button to start Android loading
4. Adding languages to Android Operating SystemBU

Den nye HTC Evo kan jo nærmest ikke sammenlignes med HTC HD2. Andet batteri, HDMI udgang, større kamera, front kamera osv osv. Så nej.

Short version @English:
No. - The Evo has different hardware.
Alright, i booted the image... and the flashlight turned on for a sec, then everything turned black... thats it right?
i had to swap the default.txt to get haret to boot :/
This is only somewhat related, but nonetheless should make people less hesitant about trying android if and when we have a working ROM.
I talked to TMobile (US), and, while you cannot use an Android device on a Smartphone plan (which is what the HD2 uses), you can switch back and forth, more or less at will, between Android and Smartphone data plans. Knowing this will certainly come in handy when actually trying to connect to the internet.
Personally, I just purchased the HD2, and after using a G1 with Android for a year and a half, I feel like I am going to puke. Why is Winmo such a confusing mess? For some reason I thought it was a mature operating system, but it feels much less polished and stable than Android. Back to the store with it until linux is cracked!
should i sell my nexus one or the htc hd2? hopfully we see android on this thing and i might consider keeping the htc hd2....what u guys think? keep or sell? the hd2 screen makes my nexus one look silly...ha
ok a bit further on .. I managed to find a working (ahem) config for usbnet .. i have managed to ping my leo from my linux box and managed to get a telnet prompt .. The telnet does not fully let me in due to lack of job control i think but for now this is cool ..
Markinus is working on refining this work and making the config default so we can all benefit without the pain ..
for now if you want to see (well my brain dumps and some other output ...

and try the Image, root filesystem and default.txt (and dot-config if your kernel compile inclined)
The shell is crashy and not useful yet ...

Not as far as i have heard ..
i've a questino though @ devs. you said that the kernel is the difficult part... and after that we can easily get linux etc on it? even maemo ?.. since it's based on linux
just wanted to drop in and say hi. unfortunately there's no news yet regarding the freeze problem.
that video is just a joke. some VNC client as they say on the site. as you can see he has winmo screenlock ^^
once we have the kernel problem fixed of course you can run maemo on the hd2.
edit: btw, any datasheet news ?
It's kinda quiet in here since the recent news about WP7S.
Thanx for the update DCordes, can you put into perspective on where about you guys are then?
Is Linux booting?
If so, how is it running?
What hardware are you having problems with?
What hardware is working?
Do you have a projected ET for having Android on the HD2? Even if not finalised, but maybe first Boot?
Thanx
Keep up the good work guys (DCordes, Netripper, Markinus, CR2, Tidsk and the rest of the guys)
Seg
it's actually all in the first post. we have that problem with the kernel freezing and we don't know why yet. that's the big show stopper right now.
except for that the overall situation looks very good! sd card and even usb host is working already ^^
Hi from France,
No idea about the kernel freeze problem ... What should happen after SD card driver being loaded ?
About the multitouch datasheet, I've been searching for it for 2 days, I didn't find anything. I just asked Elan about the release date of this. Waiting for reply ...
Thanks for your work

for me it crashes after init is executed (initrd or extracted to mmc, no difference) or when rootdelay is added in cmdline.

thanks I'm very curiious if somebody will get a reply when I tried the same thing for an aptina camera module they never answered.
with usb host working it's actually not so critical. we could use usb mouse or keyboard until we have a working leo ts driver.

I can't speak for the other devs but I personally never said such things.
Well, the guys that are really actively working on this are written in the first post.
Anyway, Tigerzen, Cass_VM and me, we're working on this with more relax, but we're only active testers and rarely we've helped in the kernel development (if we have).
There are many things working now, but what we really need is a datasheet for our Elan digitizer(/controller) for developing a driver for our touchscreen.
Hoping the best....

i found this in xperia x10 general section maybe we should have the same thread in our general section
[source] xperia x10 general section from kloud_
I was going through another site & came across a Terminology Guide. I couldn’t find something similar here so just wanted to take it upon myself to create a well organized post providing abbreviations & terminology so that any one, Master or Newbie, can have a quick reference guide to all things droid. I myself do not know everything but I do know some things & I believe with some help from the moderators & contributing members of xda-developers, we can throw together a one-stop-shop for all the droid info.
A special thanks to Sam Fisher at droidforums for the inspiration!!
Thanks to My_Immortal, OmegaRED^ & Spaarc for their suggestions & information shared!
________________
ADK: Android Development Kit, What people use to develop anything for the Android such as ROM's
The ADK (Android development kit) is divided into 3 parts
1. Android SDK (Software development Kit): used to make easy programs which only require touch & some sensors , e.g. Games
2. Android NDK ( Native Development Kit): this is used to Create apps which require Hardware or Use the native binaries & libraries of Android , eg. Camera , CyanogenMod Settings, Oxygen Settings , etc.
3. Android PDK ( Platform Development Kit): As the name suggests this is the main kit which allows to make all ".mk" files (eg. Android.mk , etc) & most of the files found on github
Basically Dev's like FXP , Z , Achotjan , kxhawkins , etc. Use the PDK to make AOSP/CM7 ROMs from source
& Also use NDK to edit the system apk's etc.. to make it stable
adb: Android Debug Bridge, a command-line debugging application included with the SDK. It provides tools to browse the device, copy tools on the device, & forward ports for debugging. If you are developing in Eclipse using the ADT Plugin, adb is integrated into your development environment.
AOSP: Android Open System Project, usually you will see this term when referring to a program or ROM. This will mean that the program or ROM was taken from Google & does not contain any modifications done by the phone Manufacturer or the phone service provider. This is Android the way Google intended.
Baseband or Radio: In communications & signal processing, the baseband describes signals & systems whose range of the frequencies measured from close to 0 hertz to a cut-off frequency, a maximum bandwidth or highest signal frequency; it is sometimes used to describe frequencies starting close to zero
Boot Loader/SPL: In literal terms, boot loader is code that is executed before any Operating System starts to run. The concept of boot loaders is universal to virtually all Operating systems that includes operating systems on your PC, laptop, Smartphone, & other such devices. Boot loaders basically package the instructions to boot operating system kernel & most of them also have their own debugging or modification environment. As the boot loader kicks off before any piece of software on your device, it makes it extremely processor specific & every motherboard has its own boot loader.
Boot Loader/SPL (Unlocked): A locked or unlocked boot loader is what gives you access to “root.” “Root” is another big word in the Android community. If you “root” a device, it means you have “super user” access or “administrator” access to the operating system that runs on your phone. Root access of your Android device gives you the ability to flash ROMs.
One of the most popular ROMs was created by a team called the CyanogenMod(CM), & their current rom is CM7, which is built on Android 2.3 Gingerbread. What this means is that if you have a phone that has an unlocked boot loader & root access, you can flash the CM7 ROM to your phone with a couple more steps. This also means that you can get access to most of the features in the latest version of Android that is commercially available, without having to wait for your manufacturer or carrier to give you an official update.
Boot Loop: Simply means something is preventing the phone from completing it's boot cycle & is stuck between the boot animation & the unlock screen, creating a looped animation. This is often fixed by either reloading a NAndroid, or Reflashing a ROM from the xRecovery/ClockworkMod Recovery/Flashtool.
Brick or Bricked: Jargon for a completely unrecoverable device, (no more than a brick or paperweight)
Note: It is my understanding that radio will boot first, followed by other systems. So it is IMPORTANT that your radio image/version will work with your SPL image/version. This is the one & only reason for phones being bricked. You cannot brick your phone by flashing a ROM or Boot image or recovery image. Once you flash the wrong radio for the SPL, the only known method of recovery is to send the phone back into SE for repair.
How do I know the phone is hard-bricked? A hard-bricked phone cannot boot into boot loader, recovery, or into normal operation modes. You cannot connect to a hard-bricked phone via adb or fastboot. You can only see one screen on the phone & it will be the first splash screen.
Bug or Software Bug: An Error or flaw in software that produces a failure or unexpected/unwanted result. Typically created from incorrect code, this is why some ROMs are better & smoother running than others because developers have taken the time to input "perfect" code (read put in a lot of hours & hard work)
Busybox: A single multicall binary that packages the functionality of most widely used standard Unix tools, BusyBox provides a fairly complete environment for any small or embedded system.
COMPCACHE: (compressed caching) is, in short, virtual swap, setting aside a certain percentage (usually 25%) of your RAM as 'compressed' swap. Compcache compresses the data that would normally go to swap, then moves it back into RAM, and reverses the process when moving it out of the 'compressed' swap. However, this is a classic space-time tradeoff. You effectively get more RAM from the compression, but it is slower than 'normal' RAM due to the CPU time required to compress and decompress the swapped pages.
ClockworkMod: A recovery program that is often used to apply updates, ROMs, or create a back up or restore a backup file
Dalvik: An open source, register-based virtual machine (VM) that’s part of the Android OS. The Dalvik VM executes files in the Dalvik Executable (.dex) format & relies on the Linux kernel for additional functionality like threading & low-level memory management. The virtual machine is register-based, and it can run classes compiled by a Java language compiler that have been transformed into its native format using the included "dx" tool.
Dalvik Cache: A program cache area for the program Dalvik. Dalvik is a java based virtual machine that is the basis for running your programs (the ones that have the .apk extension). In order to make access times faster (because there's not JIT (just in time) compiler installed by default), the dalvik-cache is the result of dalvik doing a optimization of the running program. It's similar to the prefetch files in Windows.
DDMS: Dalvik Debug Monitor Service, a GUI debugging application included with the SDK. It provides screen capture, log dump, and process examination capabilities. If you are developing in Eclipse using the ADT Plugin, DDMS is integrated into your development environment.
Deep Sleep: A state when the CPU is off, display dark, device is waiting for external input.
De-odex: Apk files have respective odexes that devs use to supposedly save space. Deodexing means you convert it back to a .dex file & put it back inside the apk. This allows you to easily replace files (not having to worry about odexes), but the main point was to deodex services.jar so that you can change all text to different colors (such as the clock color to white) & to deodex services.jar, you need to deodex everything.
Dev. or Developer: An individual that creates, or alters a file in such a manner as to advance the program
Drawable: A compiled visual resource that can be used as a background, title, or other part of the screen. A drawable is typically loaded into another UI element, for example as a background image. A drawable is not able to receive events, but does assign various other properties such as "state" and scheduling, to enable subclasses such as animation objects or image libraries. Many drawable objects are loaded from drawable resource files — xml or bitmap files that describe the image. Drawable resources are compiled into subclasses of android.graphics.drawable. For more information about drawables and other resources.
Fastboot: Protocol used to update the flash file system in Android devices from a host over USB. It allows flashing of unsigned partition images.
Flash: Rewrite the software/firmware on your phone using a computer to "flash" or completely rewrite the memory (ROM) of your phone. This is done using ODIN.
Flash Memory: a program technology that can be electrically erased & reprogrammed
Kernel: The main component of Android operating system.
It is a bridge between applications & the actual data processing done at the hardware level.
The kernel's responsibilities include managing the system's resources (the communication between hardware & software components).
[Usually as a basic component of an operating system, a kernel can provide the lowest-level abstraction layer for the resources
(especially processors & I/O devices) that application software must control to perform its function.
It typically makes these facilities available to application processes through inter-process communication mechanisms & system calls.
Operating system tasks are done differently by different kernels, depending on their design & implementation.]
Manifest File: An XML file that each application must define, to describe the application's package name, version, components (activities, intent filters, services), imported libraries, and describes the various activities, and so on. See The AndroidManifest.xml File for complete information.
Nine-patch / 9-patch / Ninepatch image
A re-sizeable bitmap resource that can be used for backgrounds or other images on the device.
Nandroid or Nandroid Backup: A file typically created in the custom recovery program, such as xRecovery, that is a carbon copy of whatever state your phone is in before a drastic change is made. The file then can be moved onto or off of the SD card for later use in case something should go wrong in the ROM or Update, or a Boot Loop occurs
ODIN: It is the program you can use to flash phones.
e.g. : 'Odin Multi-Downloader v3.95' is used to flash the Samsung Galaxy. It's usually included in firmware packs.
OEM: Original Equipment Manufacturer, the people who actually put together electronic hardware. Also refers to any equipment original to the phone, or produced by the company for the phone
OpenGL ES: Android provides OpenGL ES libraries that you can use for fast, complex 3D images. It is harder to use than a Canvas object, but better for 3D objects. The android.opengl and javax.microedition.khronos.opengles packages expose OpenGL ES functionality.
OS: Operating system, I.E. Windows Vista, LINUX or MAC or Android
OTA: Over-the-Air; method T-Mobile, & some other phone companies, uses to update Android phones. The new versions of Android are developed by Google & then released to OEM's, Sony Ericsson in our case. The OEM then writes drivers that enable the new software to work on the phone's hardware. They also develop any specialized UI (user interface), like Timescape & Mediascape, or other software they want to include. Once this is complete, they turn it over to the cell phone company, (e.g.)Tmobile, who then have to do the final checks to make sure the update works, & then distributes it over there data network using their cell transmitters.
Overclocking (OC): Speeding up the CPU past the factory presets to achieve a faster & more responsive device (prolonged run can be injurious to your device, so be careful.)
ROM: Read Only Memory, a program used to make changes to anything from the look of the home screen to icons to custom boot animation
Root: Common word associated with giving a user "super user" access to their phones programming & other various aspects that would normally not be possible, also known as "Jailbroken" for iPhone's, "Administrator Rights" in Windows OS.
Shell or SSH: The shell is the layer of programming that understands & executes the commands a user enters. In some systems, the shell is called a command interpreter. A shell usually implies an interface with a command syntax (think of the DOS operating system & its "C:>" prompts & user commands such as "dir" & "edit"). secure shell or ssh is a network protocol that allows data to be exchanged using a secure channel between two networked devices
SQLite: An embedded relational database management system contained in a relatively small (~275 kB) C programming library. It is multitasking concerning reads. Writes can be done only one-at-a-time. It is a popular choice for local/client storage on web browsers. It has many bindings to programming languages. It is arguably the most widely used database engine, as it is used today by several widespread browsers, operating systems, embedded systems among others
Stock: Simply means an unaltered state, such as when you first purchase your phone fromVerizon/Your Service Provider or when you repair your phone using PC Companion or SE Update Service(SEUS)
SU: "Super user", or root permissions
SWAP: is, in short, virtual RAM. With swap, a small portion of the hard drive is set aside and used like RAM. The computer will attempt to keep as much information as possible in RAM until the RAM is full. At that point, the computer will begin moving inactive blocks of memory (called pages) to the hard disk, freeing up RAM for active processes. If one of the pages on the hard disk needs to be accessed again, it will be moved back into RAM, and a different inactive page in RAM will be moved onto the hard disk ('swapped'). The trade off is disks and SD cards are considerably slower than physical RAM, so when something needs to be swapped, there is a noticeable performance hit.
Unlike traditional swap, Android's Memory Manager kills inactive processes to free up memory. Android signals to the process, then the process will usually write out a small bit of specific information about its state (for example, Google Maps may write out the map view coordinates; Browser might write the URL of the page being viewed) and then the process exits. When you next access that application, it is restarted: the application is loaded from storage, and retrieves the state information that it saved when it last closed. In some applications, this makes it seem as if the application never closed at all. This is not much different from traditional swap, except that Android apps are specially programed to write out very specific information, making Android's Memory Manager more efficient that swap.
Theme: A set of icons, backgrounds & app trays that change the aesthetics of the overall look of the Android & its applications. It has a set of properties (text size, background color, and so on) bundled together to define various default display settings. Android provides a few standard themes, listed in R.style (starting with "Theme_").
TUN/TAP: Refers to a network TUNnel, operates within layer 3 packets, or ip packets. Packets sent by a system via a TUN/TAP device are delivered to a user-space program that attaches itself to the device. A user space program may also pass packets into a TUN/TAP device. In this case TUN/TAP device delivers (or "injects") these packets to the operating system's network stack thus emulating their reception from an external source.
Underclocking(UC): Slowing down the CPU mainly to limit battery usage
Undervolting(UV): Basically keeping the clock speed same (or overclocking it) & reduce the voltage at each cpu cycle.
xRecovery: A recovery program based on the ClockworkMod Recovery sources used to apply updates, ROMs, or create a back up or restore a backup file
File Types:
.dex: Compiled Android application code file. Android programs are compiled into .dex (Dalvik Executable) files, which are in turn zipped into a single .apk file on the device. .dex files can be created by automatically translating compiled applications written in the Java programming language.
.sbf: Summation Briefcase File
.apk or APK's: An .apk file extension denotes an Android Package (APK) file, an .apk file can be opened & inspected using common archive tools. Each Android application is compiled and packaged in a single file that includes all of the application's code (.dex files), resources, assets, and manifest file. The application package file can have any name but must use the .apk extension. For example: myExampleAppname.apk. For convenience, an application package file is often referred to as an ".apk".
.tar: Similar to a zip file(derived from tape archive), a tar file archives multiple files into one file
.tgz: TGZ files (gnu-zipped .tar file) are commonly used as install packages for Slackware Linux.
pheeeeww!!This took sometime!!
Well this is all I can think of off the top of my head but as I think of more I will edit them in here & I encourage the mods to put things that I either forgot or just simply am not aware of. Also I request fellow user to suggest any terms frequently used & not added or any discrepancies found, kindly PM me!!
Thank you & happy hacking/flashing!!

Hi everybody,
It's my first post on XDA, because I always got my answer on the differents topics I found.
I'm actually working on monitoring network. I use the firmware provide by these brillant guys :
http bcmon blogspot ie/.
I want to developp an native code to write a easy airodump-ng like, to monitoring the traffic close to my device.
I need to use radiotap headers to do what I want, and of course a monitoring access to my wireless card.
So I reverse the bcmon.apk provided by bcmon team, to look how they lauch airodump-ng in a term. I noticed they use LD_SHARED=`pwd`/libs LD_PRELOAD=`pwd`/fakedriver.so.
My first problems : my toolchain (provided by NDK) don't have radiotap header access, and I really don't know how to add these last one to it.
My second problems : how to compile my code with the LD_SHARED/ LD_PRELOAD libraries used by bcmon drivers to ensure I'll be able to execute my code with the monitor mode activated. I think that I will have to add the libs contained on /data/data/com.bcmon.bcmon/files/libs
on these of my toolchains, but I really don't know.
I read a lot papers to understand how linking works in C, but I'm probably still missing something.
I really don't know how to improve my toolchain, and I'm quite anoyed because I haven't progressed in my work for days...
Any help will be really appreciated.
Thanks a Million
Ant.
I found a solution few weeks ago.
I had linking erros.
I reserved the .apk provided by bcmon guys.
For those that want to develop using monitoring functionnalities, there is the way to do :
LD_PRELOAD=/data/data/com.bcmon.bcmon/files/libs/libfake_driver.so LD_LIBRARY_PATH=/data/data/com.bcmon.bcmon/files/libs ./yourprog
If you want to comiple your code using some of their libraries, for example pcap libraries I have done the fellowing stuffs :
1- found radiotap headers, and pcap headers on github likes websites.
2- try to cross compile with the headers
3- Correct the erros (like typedef missing ...)
4- Build your make file adding name of the libraries :
GCC={your toolchain}
FLAGS={your flags}
LIBS=libfake_driver.so \
libpacap.so.1
OBJ = {your obj}
output :
$(GCC) $(OBJ) -c {yoursrcfile) -o {output} $(FLAGS) $(LIBS)
Hope it 'll help.

I am trying to download the source code for SM-N9005 from Samsung Open Source place (however my downloads keep cancelling, 800MB on 2Mb/s connection )
When it eventually downloads, will I be able to compile a kernel for my phone with SELinux set to permissive instead of enforcing?
I have NEVER done custom kernel development but I think this is a good time to start
Current status of my Note 3
Root,Unlocked bootloader,twrp recovery and the firmware is OF1.
The reason I think I need permissive mode is because I am having problems with trying to get linux deploy to work.
From reading some posts I have gathered that selinux might be the problem.
To get into permissive mode I need to replace the kernel I think, how is permissive mode done ?
thank you.
The phantomOne kernel ("hlte-vzw" version) seems to be permissive. You can use it with the AryaMod ROM if you like.*
There are kernel build-time configuration option(s) determining whether SELinux is (a) disabled, (b) alterable by kernel boot arguments (or post-boot changes), or (c) permanently enabled and immutable, and finally (d) either permissive or enforcing. In the case of (b) the default (absent a kernel boot command line argument) could be either permissive or enforcing.
Some of the above combinations are not used in practice - e.g. it makes little sense to be immutable and permissive.
In any event, you would have to see the kernel build configuration files to know what the exact setup was (or the kernel has /proc/config.gz enabled).
Typically a vendor will use "permissive" as a stepping stone towards getting full-up immutable, enforcing SElinux running without problems: the kernel will issue violation warnings without enforcing the SElinux constraints, so that kernel logs can be used to diagnose improper setups of SElinux execution contexts (domains) and filesystem extended attributes on a live testing system.
* I'm on NC4 bootloader; ymmv.
W T F no write access to ext sd card as default ?
still poking about trying to figure out why the linux install script's dont work.
I have discovered that as a default programs or apps dont have the permissions to write to the extsdcard . The extsdcard is read only. I think that actually is my problem.
where do I look to perminatly change my permissions on my extsdcard to 777 for all users and groups.
does android have somthing like an fstab file or mounting options ??
If it's any encouragement to you, I got the "Linux deploy" app to work on
AryaMod6.6 + phantomOne kernel (permissive SELinux).
I had similar troubles creating the initial container on the /sdcard, and I'm pretty sure that was just operator error because the interface is not intuitive and of course I completely failed to RTFM. So, maybe the container creation issue has nothing to do with SELinux at all.
Useful hint: with a default "linux" (==debian jessie ARM) profile container, the default username for all the services (httpd, sshd, vnc) is "android", and the initial passwords are found in two different places: under the "Settings" menu pick for httpd and telnetd, and under the little "inbox" icon menu for the profile for sshd and vnc. I had to use "apt-get install tightvncserver" to get vncserver up and running from the ssh command line. ("sudo /bin/bash" first).
I had to log in to the phone via adb and do a " netstat -n -a | grep 'tcp.*LISTEN' " to convince myself the various servers were up. That helped a bunch. httpd on :5080, telnetd on :5023, vncserver on :5901.
good luck, I struggled with it.
What are you going to use this for? I suppose if you have access to a full native-ARM Linux environment, perhaps it is easier to build native tools against libc without the constraints of bionic and the NDK?

What I am trying to do is explore just how well I can really use this brilliantly wonderful device as my main computer. I have good reasons for this but there all related to my personal circumstances and I won't bore you with the details, sufice it to say that I am now living in a electricity/power scarce inviroment and a cell phone is about as power efficient as I can get and have reasonably powerfull hardware.
I had considered sbc's like the Rasb. pi but there are none that even come close to the capabilities of this phone.
GPS,wifi,cellular,acceleromiter etc.
In an Ideal world I could wipe android fully from the phone and load a distro of linux that fully supported all the hard ware of the note 3 giving me as fast and lean a computing enviroment to work with Or perhaps a duel boot configuration like grub boot either android or linux.
Phantom kernel and lss works great ..been going back and forth with the latest international roms since there's not too much happening on our Verizon forum.
