Direct link to the precompiled ROM: http://www.filefactory.com/file/cfe8147/GWK74-buzz-20111111.zip (please hit thanks if you find this ROM useful )
Setting up the development environment
Install the current stable Debian: squeeze (6.0) amd64 (not the i386 version, and not the testing/unstable version). Do not ask me for a working Ubuntu version -- I don't know. Use Debian instead
Code:
apt-get install python git bzip2 zip unzip lzma patch bison flex \
make gcc g++ gcc-multilib g++-multilib gperf libz-dev lib32z-dev curl \
libncurses5-dev lib32ncurses5-dev libx11-dev openjdk-6-jdk
Downloading the sources and other packages
AOSP 2.3.7r1 (GWK74) is the current version of the AOSP
arco's 2.6.35 kernel is the base for the kernel we will build
koush's vendor files contain the HTC proprietary blobs for buzz
CyanogenMod's device/htc/buzz
Code:
git clone https://github.com/arco/buzz-kernel-2.6.35.git
git clone https://github.com/koush/proprietary_vendor_htc
git clone https://github.com/CyanogenMod/android_device_htc_buzz.git -b gingerbread-release
Code:
mkdir ~/bin
curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
chmod +x ~/bin/repo
export PATH=~/bin:$PATH
Code:
mkdir 2.3.7_r1; cd 2.3.7_r1
repo init -u https://android.googlesource.com/platform/manifest -b android-2.3.7_r1
repo sync
mkdir -p vendor/htc
cp -r ../proprietary_vendor_htc/buzz vendor/htc
cp -r ../android_device_htc_buzz device/htc/buzz
The "repo sync" may take a while, so please be patient
Compiling the kernel
Code:
cd ../buzz-kernel-2.6.35
make ARCH=arm buzz_defconfig
At this point you can edit .config and change CONFIG_MSM_CPU_FREQ_ONDEMAND_MAX to overclock the CPU, for example setting it to 700 MHz.
Code:
make ARCH=arm -j4 CROSS_COMPILE=../2.3.7_r1/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-
cp arch/arm/boot/zImage ../2.3.7_r1/device/htc/buzz/prebuilt/kernel
cp drivers/net/wireless/bcm4329/bcm4329.ko ../2.3.7_r1/device/htc/buzz/prebuilt/bcm4329.ko
Patching the sources
Several files must be patched. The following patches are from CyanogenMod 7:
armv6j.mk.patch: adds a new architecture (ARMv6J) which targets the MSM7225
browser.patch: provides a small fix to prevent the Browser from crashing
camera.patch: enables the use of Froyo (2.2) libcamera.so
dalvik-armv6j.patch: adds a new ARMv6J target for JIT compilation by the Dalvik runtime environment
gpsshim.patch: enables the use of Froyo (2.2) libgps.so
libagl.patch: enables the use of copybit to make software OpenGL support a bit faster (I think)
surfaceflinger.patch: another cool patch from CM7 when transparency is not supported
The following patches were made by myself:
config.xml.patch: several values which are present in CM7 but not AOSP must be disabled
LOCAL_MODULE_TAGS.patch: a bunch of Android.mk in hardware/msm7k lack this variable
ota-no-recovery.patch: prevent ota_from_target_files from flashing the recovery (we like our ClockworkMod better )
vendork-blobs.mk.patch: adds library libOmxCore.so which is needed by mediaserver
The following patches are from Google:
apns-conf.xml.patch: adds a bunch of APNs that are not present in the default AOSP file
For your convenience, I have included all the patches in a single file, which is attached to this post (patch-buzz.zip).
Code:
cd ../2.3.7_r1
wget -O patch-buzz.zip "http://forum.xda-developers.com/attachment.php?attachmentid=779411"
unzip patch-buzz.zip; ./patch-buzz/apply.sh
ln -s full.mk build/target/product/full_base.mk
rm -rf device/htc/buzz/overlay/packages
Setting up a custom vendor
At this point you may want to add a number of custom additions, for example:
a simple boot animation: http://forum.cyanogenmod.com/topic/19198-simple-generic-boot-animation/
Superuser root package: http://forum.xda-developers.com/showthread.php?t=682828
Torch from CyanogenMod: http://download.cyanogenmod.com/?type=stable&device=buzz
Talk and Android Market: http://wiki.cyanogenmod.com/wiki/Latest_Version
Google Maps for WildFire: http://forum.xda-developers.com/showpost.php?p=15218646&postcount=4
Code:
mkdir vendor/xdbg; cd vendor/xdbg
wget http://duck.at.shangtai.net/files/android/bootanimation.zip
wget -O su-2.3.6.1-ef-signed.zip http://dl.dropbox.com/u/6408470/su-releases/su-2.3.6.1-ef-signed.zip
wget http://download.cyanogenmod.com/get/update-cm-7.1.0-buzz-signed.zip
Also download gapps from http://goo-inside.me/gapps/gapps-gb-20110828-signed.zip , put it in 2.3.7_r1/vendor/xdbg and run:
Code:
unzip su-2.3.6.1-ef-signed.zip
wget -O system/app/Maps.apk http://forum.xda-developers.com/attachment.php?attachmentid=641716
unzip update-cm-7.1.0-buzz-signed.zip system/lib/libOmxCore.so
unzip update-cm-7.1.0-buzz-signed.zip system/app/Torch.apk
unzip -o gapps-gb-20110828-signed.zip
mv system/lib/libOmxCore.so ../htc/buzz/proprietary
I haven't tried it, but you can try to include the LatinIME.apk from CM7 in order to get the dictionaries (not included by default in AOSP).
Now we'll create the Makefile that specifies which files are to be copied in the ROM. Be careful when copy-pasting to not truncate the last line which is quite long:
Code:
echo "\$(call inherit-product, vendor/xdbg/xdbg.mk)" >>../../device/htc/buzz/buzz.mk
cat >xdbg.mk <<"EOF"

Building the ROM
Code:
cd ../..
. build/envsetup.sh
lunch [I](choose htc_buzz-userdebug)[/I]
make -j5 otapackage WITH_DEXPREOPT=true[I]
(5 is for a quad-core with 4GB of RAM. you can decrease it if you have less RAM)[/I]
Remove WITH_DEXPREOPT=true above to generate a de-odexed ROM.
Advantage of a de-odexed ROM: you can easily replace APKs or JARs in /system.
Disadvantages: the first boot takes a while because all APKs must be odexed. Also the dalkvik cache takes a significant amount of space (up to 50 MB) in /data (CM7 uses /cache so this is not a problem).
Note that you will not need the Android SDK since adb and other tools will be present in the PATH after you run lunch and the out/host part is compiled.
The generated ROM is out/target/product/buzz/htc_buzz-ota-*.zip. Wiping the whole data partition in ClockworkMod is required if your previous ROM was built with different signing keys.
Finally, I'd like to thank everyone who made this possible: cyanogen, arco, koush, HDCRJacob, schiznik, _thalamus & AdamG, ben1066, nhnt11 and everyone else who contributed on porting the AOSP on the WildFire. You guys are awesome
reserved
also reserved for future use
wow
Thats a very comprehensive guide )
I think you may be overcomplicating things though - if you run "make -jX otapackage" instead of just make, the build process will create a flashable zip for you.
Further to this, you can create your own vendor_blah repo, which will allow you to remove things like the recovery from the otapackage, and set a custom modversion during the build

Super cool! I'll add your suggestions in a later release I need to get back my WildFire to test it all, so far I have great hope to fix the graphics with the patches from arco68. BTW, in your testing, would you recomment the 2.6.32 (htc-kernel-buzz) or 2.6.35 from arco's GitHub? Both seem fairly similar to me although the 2.6.35 get updated more often.

Hey arco68 Any comment on the 2.6.32.41 vs 2.6.35.10 kernels? I'd say the 2.6.35 should be more fitted to GR* (like 2.6.32 was for FR*), but I'd really like to hear your opinion on this.
I prefer 2.6.35 for gingerbread, as it's easier to keep up to date and patch with stuff from CAF and Google's kernels.

Yea 2.6.35 is the gb kernel. I can't use make bacon as I don't use cm's vendor, make devnull does the same though
Many thanks for the input arco68

Do you know what would be so nice? It would be really nice is someone could update this to the newest source so that it could actually be relivant
Minor thread hijack...
If you want to build Oxygen for buzz - you can do the below:
Code:
mkdir android ; cd android/
repo init -u [email protected]:schiznik/oxygen_manifest.git -b gingerbread
repo sync
. build/envsetup.sh
lunch 8
make oxygen
You can optionally use "repo -j20 sync" to sync 20 of the repo's at once, and make -jX oxygen, where X is the number of CPU cores that you are using to build.
Once completed, there is a update-oxygen-*.zip file in out/target/product/buzz/ that can be flashed.
Nice !Very interisting
Thanks a lot, schiznik. I'll update the main thread.
EDIT: main thread updated. the sources compile, although I haven't tested the resulting ROM yet.

For those who have tried this and get the reply "public key error". Try editing the repo init line to read "repo init -u https://github.com/schiznik/oxygen_manifest -b gingerbread" this works for me. I'm busy report syncing now, will inform you further, when it completes.

Building CM9 from Sources for O2X
This Guide is a Step by Step Guide to Build CM9 from official CM9 Sources.
It based on:
aMpeX`s [TUTORIAL] The Step-By-Step guide to build Cyanogenmod7 for the LG Optimus 2X
loganmc10`s [GUIDE] Building CM9 for G2X
I only change to P990, respectively CM9 and add the fix for working Baseband
You need:
- a installed Linux, (I use Ubuntu 11.10, 64 Bit)
- a fast PC or Notebook is recommended
- a fast internet-connections is recommended, (you have to download several GBs)
There are 10 Steps, (8 for building, and 2 optionals ):
1. Installing Build-Packages
2. Install and setup Android-SDK
3. Update path
4. Create directories
5. Install repository and download CM9 Sources
6. Fix for non working camera
6a. Fix the known issues
7. Compiling Unofficial CM9 Build
8. Fix unknown Baseband
9. Extended building
10. Optional changes
Some infos before start:
- read the whole Guide carefully, (possibly you have to read it a few times, untill you understand all steps)
- if you do it exactly as explained, there should be no problems, and the result is a working Unofficial CM9-Build
- don`t login to Linux as root
- if you get problems, feel free to PM me, if you can`t post in Dev-Forum
lets start,
1. Installing Build-Packages
install this for 32 bit and 64 bit:
Terminal:
type:
Code:
sudo apt-get install git-core gnupg flex bison gperf libsdl1.2-dev libesd0-dev libwxgtk2.6-dev squashfs-tools build-essential zip curl libncurses5-dev zlib1g-dev openjdk-6-jdk pngcrush schedtool
NOTE:
this will install Open-JDK instead of Sun-JDK,
(Sun-JDK isn`t longer official available for Ubuntu)
this will result in an error message at the beginning of compiling,
just ignore it, compiling will working fine.
If you want to install Sun-JDK instead of Open-JDK,
the user tonyp has made a tutorial.
use this line instead of above one
Terminal:
type:
Code:
sudo apt-get install git-core gnupg flex bison gperf libsdl1.2-dev libesd0-dev libwxgtk2.6-dev squashfs-tools build-essential zip curl libncurses5-dev zlib1g-dev pngcrush schedtool
than go to this tutorial
for me the tutorial above doesn`t work (Ubuntu 11.10 64 Bit)
this is working for me:
open terminal:
Code:
sudo add-apt-repository ppa:ferramroberto/java
Code:
sudo apt-get update
Code:
sudo apt-get install sun-java6-jdk sun-java6-plugin
Code:
sudo update-alternatives --config java
(note: you have to press the tab button to be able to press ok, after the last command )
install this for 64 bit also:
Terminal:
type:
Code:
sudo apt-get install g++-multilib lib32z1-dev lib32ncurses5-dev lib32readline-gplv2-dev gcc-4.4-multilib g++-4.4-multilib
2. Install and setup Android-SDK
Download newest Android-SDK from here (Linux (i386) )
Extract the Zip-Package to a directory of your choice
Terminal:
navigate to the tools-folder of Android-SDK and type:
Code:
./android
this will launch the AVD-Manager
check repository, select newest repository, and click install packages
3. Update path
go to your Home-Directory, and press CTRL + H to show hidden files,
open .bashrc
and add this:
Code:
export PATH="/home/<yourusername>/<path to the android SDK >/platform-tools/:${PATH}"
export PATH="/home/<yourusername>/bin/:${PATH}"
now you have to log out and in again for the changes take effect.
now check if changes are working,
Terminal:
type:
Code:
adb devices
you should see something like this:
[email protected]:~$ adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached

4. Create directories
Terminal:
type:
Code:
mkdir -p ~/bin
Code:
mkdir -p ~/android/system
5. Install repository and download CM9 Sources
Install repository
Terminal:
type:
Code:
curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
Code:
chmod a+x ~/bin/repo
Code:
cd ~/android/system/
Code:
repo init -u git://github.com/CyanogenMod/android.git -b ics
enter name, email adress, and choose if you want colors or not
Download CM9 Sources:
Terminal:
type:
Code:
cd ~/android/system/
Code:
repo sync
depending on your internet connection speed this can take several hours
press CTRL + H
go to :
/android/system/.repo/
create:
local_manifest.xml
paste into local_manifest.xml:
Code:
<?xml version="1.0" encoding="UTF-8"?>

6. Fix for non working camera
download this zip-package MediaFire SolidFiles.
(I don`t make this patch, and don`t know who had made it, if you made it PM me and I`ll give credit for your work)
Extract the Zip-Package to a directory of your choice.
Terminal:
type:
Code:
cd ~/android/system
Code:
patch -p1 <
NOTE: after "<" there has to be a "blank space" (press spacebar)
now drop the first ...diff file from extracted package into terminal, the path will be automatically added,
run the created command,
the same procedure for the other 4 files
6a. Fix the known issues
for broken building:
open:
device/lge/p990/BoardConfig.mk
delete line:
Code:
BOARD_TOUCH_RECOVERY := true
For mobile data fix:
place this file to android/system/system/core/init/ (overwrite excisting file),
7. Compiling Unofficial CM9 Build
Terminal:
type:
Code:
~/android/system/vendor/cm/get-prebuilts
Code:
cd ~/android/system/
Code:
. build/envsetup.sh
Code:
brunch p990
depending on your PC or Notebooks specs compiling will take from 30 minutes to several hours
you can find your Rom-Zip-Package at:
/android/system/out/target/product/p990/
Click to expand...
Click to collapse
8. Fix unknown Baseband
open your Rom-Zip-Package and extract /system/build.prop
(don`t close Archivmanager)
open build.prop:
delete line:
ro.modversion=9-...-UNOFFICIAL-p990
Click to expand...
Click to collapse
(thanks to owain94 for deleting line info)
find line:
ro.cm.version=9-...-UNOFFICIAL-p990
Click to expand...
Click to collapse
replace this line with:
ro.cm.version=9.0.0-RC1-p990-UNOFFICIAL
Click to expand...
Click to collapse
save build.prop
drop modded build.prop into Archivemanager (/system, overwrite existing file)
Now your Unofficial CM9 Build is ready to install
------------------------------------------------------------------------------------------------------------------------------------------------------------
9. Extended building:
I decided to make a optional 9. Step to have a better building experience
(all tipps by owain94, thanks)
This Step is a replacement for Step 7!
Terminal:
type:
Code:
cd ~/android/system && clear && cd vendor/cm && ./get-prebuilts && cd ../../ && clear && . build/envsetup.sh && brunch p990 2> warn.log
this command downloads the cm-prebuilds,
sets up the build environment,
start the building,
exports all warnings and errors to a text file
and cleans the Terminal.
open another Terminal
type:
Code:
cd ~/android/system && clear && tail -f warn.log
this command cleans the terminal,
shows the warnings and errors in this second Terminal,
and keep the focus on it,
first terminal only shows the building process,
so it`s much easier to catch problems while compiling.
If you have connected two screens to your PC or Notebook,
you can also place second Terminal on second screen.
you can find your Rom-Zip-Package also at:
/android/system/out/target/product/p990/

10. Optional changes:
Fix for working torch and torch power-widget:
"activate" torch and power-widget:
open:
/android/system/packages/apps/Torch/res/values/config.xml
add or change to:
Code:
<bool name="useCameraInterface">true</bool>
open:
/android/system/packages/apps/Settings/res/values
add or change to:
Code:

The -j part isn't needed anymore the build script figure it out on their own
and for the vendor files you can ad this to the local manifest
<project name="koush/proprietary_vendor_lge.git" path="vendor/lge" remote="github" />
it is less work we don't want to do to much
also this is maybe a nice addition
Code:
clear && cd vendor/cm && ./get-prebuilts && cd ../../ && clear && . build/envsetup.sh && brunch p990 2> warn.log
i use this build line
clear - make my terminal nice and empty
cd vendor/cm && ./get-prebuilts && cd ../../ - get the cm prebuilts
clear - make the terminal clean again
. build/envsetup.sh - set up the build env
brunch p990 - lunch and bacon for the p990
2> warn.log - exports al the warnings and errors to a text file to keep the terminal clean
i have three screens attached to my pc
on one screen i run the above command (clear && cd vendor/cm && ./get-prebuilts && cd ../../ && clear && . build/envsetup.sh && brunch p990 2> warn.log)
on another screen i run this command (clear && tail -f warn.log) this will print (and keep track of) the warn.log file with all the errors and warnings
and on the other screen i do useless stuff hehe
anyway i really like to use 2 terminals it is just easier to catch problems

great guide bro.
Edit:
If anyone wants to install the SUN JDK instead of Open JDK you can install it from the partner repository:
Code:
sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"
sudo apt-get update
sudo apt-get install sun-java6-jdk
Thanks, for your replies, I'll change my Guide at the evening.

did you sync the vendor files?
libnvdispmgr_d.so is a vendor file that cannot be build because we don't have the sources
you need to sync them from koush his github or extract the vendor files using the script in the device folder
good luck

Hm I don't think so. As far as I know the reason why Open JDK is used in Ubuntu instead of Sun JDK is that Open JDK is fully open sourced while Sun JDK still uses some pre compiled closed source binaries. Some open source fanatics might call this a security risk as they can't check the source themselves, but apart from that their shouldn't be any risks.

For any CM10 ROM, except new bootloader one, hackfest, and CM10.1
This tutorial shows you how to build CM10 kernel from RC and the CM team's source(it is their work), and using wkpark's ramhack patch or other patches
If you are uncomfortable in building the kernel, you use my flashable sample kernel at the end of the post, which uses 56 MB RAM hack.
Pre-requistes:
A Linux system
An internet connectionc
Some time and patience
But the time required for downloading resources, and building once everything is set up, is only a fraction of the time required for a full CM10 ROM
You can follow this guide, with or without having built CM10 following Raum1807's excellent CM10 building guide. At one of the places, the difference occurs whether you had built CM10 before or not, and I have listed it at that place
For a first time build, you need to follow all the steps, but 2nd time onwards, you can skip to the build step or RAM hack setting step
Instructions:
STEP 1: SETTING UP THE ENVIRONMENT
Install any CM10 ROM on the device (old bootloader, non-hackfest, non-CM10.1 one)
If you already have CM10 environment set up, skip to "Create an environment variable..." part
Install development support packages:
Debian based Linux distributions (like Ubuntu)
64bit systems:
Code:
sudo apt-get install git-core gnupg flex bison gperf build-essential \
zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \
libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 \
libgl1-mesa-dev g++-multilib mingw32 openjdk-6-jdk tofrodos \
python-markdown libxml2-utils schedtool pngcrush xsltproc zlib1g-dev:i386
then
Code:
sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so
Red Hat based Linux distributions
32bit and 64bit systems:
git gnupg java-1.6.0-openjdk-devel flex bison gperf SDL-devel esound-devel wxGTK-devel zip curl ncurses-devel zlib-devel gcc-c++ glibc-devel
64bit only:
glibc-devel.i686 libstdc++.i686 zlib-devel.i686 ncurses-devel.i686
Setting up Java (thanks to Raum for the java setup guide)
You need a Java Development Kit for building CM10. Recommended is the SUN JDK 6. As of writing the most recent version is SUN JDK 6 Update 37.
1. Download the jdk-6u37-linux-i586.bin from the Oracle/Sun Java Download Area. If you are on 64-bit Ubuntu as I am, you should grab jdk-6u37-linux-x64.bin.
2. Make the bin file executable:
Code:
$ chmod +x jdk-6u37-linux-x64.bin
3. Extract the bin file:
Code:
$ ./jdk-6u37-linux-x64.bin
4. Move the extracted folder to this this location:
Code:
$ sudo mv jdk1.6.0_37 /usr/lib/jvm/./jdk-6u37-linux-x64.bin
5. Install the new Java source in system:
Code:
$ sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk-6u37-linux-x64.bin/bin/javac 1
$ sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk-6u37-linux-x64.bin/bin/java 1
$ sudo update-alternatives --install /usr/bin/javaws javaws /usr/lib/jvm/jdk-6u37-linux-x64.bin/bin/javaws 1
$ sudo update-alternatives --install /usr/bin/javadoc javadoc /usr/lib/jvm/jdk-6u37-linux-x64.bin/bin/javadoc 1
$ sudo update-alternatives --install /usr/bin/javah javah /usr/lib/jvm/jdk-6u37-linux-x64.bin/bin/javah 1
$ sudo update-alternatives --install /usr/bin/javap javap /usr/lib/jvm/jdk-6u37-linux-x64.bin/bin/javap 1
$ sudo update-alternatives --install /usr/bin/jar jar /usr/lib/jvm/jdk-6u37-linux-x64.bin/bin/jar 1
6. Select the default Java version for your system:
Code:
$ sudo update-alternatives --config javac
$ sudo update-alternatives --config java
$ sudo update-alternatives --config javaws
$ sudo update-alternatives --config javadoc
$ sudo update-alternatives --config javah
$ sudo update-alternatives --config javap
$ sudo update-alternatives --config jar
7. Check Java version:
Code:
$ java -version
8. Verify the symlinks. Javac, Java, Javaws, Javadoc, Javah, Javap and Jar should all point to the new Java location and version:
Code:
$ ls -la /etc/alternatives/java* && ls -la /etc/alternatives/jar
Now,
If you have CM10 source fetched already (if you have built cm10)
If the directory name where the cm10 source exists is "cm10" (as in Raum's building guide)
Create an environment variable denoting the location of the android toolchain as follows:
Code:
export CCOMPILER=${HOME}/cm10/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-
Or else, replace the path/name if yours is different
(If your arm-eabi version is not 4.4.3, check the folder name and change it accordingly)
If you do not have cm10 source on your pc, then you need to download the ARM EABI Toolchain separately
Download link, ready to extract
If above does not work, download from official site here
Download and extract then, create an environment variable denoting the location of the toolchain as follows:
Code:
export CCOMPILER=[extraction directory]/bin/arm-eabi-
Download Kernel Source Code:
Code:
mkdir -p ~/kernel
cd ~/kernel
Now download RC's CM10 kernel source
In terminal, do
Old bootloader:
Code:
git clone git://github.com/CyanogenMod/lge-kernel-star.git -b jellybean
New bootloader:
Here, pengus77 has made the necessary changes in his repo, so we fetch from that
Code:
git clone git://github.com/pengus77/lge-kernel-star.git
Thus, there should be a folder named "lge-kernel-star" inside /kernel folder
Then in terminal, cd to that directory "lge-kernel-star"
Code:
cd lge-kernel-star
Getting the config file
The next step is to copy the file "/kernel/lge-kernel-star/arch/arm/configs/cyanogenmod_p990_defconfig" to "/kernel/lge-kernel-star and rename it to ".config"
using the command:
Code:
cp arch/arm/configs/cyanogenmod_p990_defconfig .config
(Thanks to tonyp for the tip!)
STEP 2: CONFIGURATION
Configure the build:
Code:
make ARCH=arm CROSS_COMPILE=$CCOMPILER oldconfig
If it happens to ask anything, just accept the defaults at every step by pressing enter.
STEP 3: APPLYING PATCHES
Applying patches like wkpark's RAM hack patch
If you skip this step, the kernel will work, but you'll have a completely stock kernel without RAM hack or other tweaks
Download wkpark's two patches from here and here, and put them in your /kernel directory
Code:
cd ~/kernel
Now to apply the patches, we use the patch command like this:
Code:
patch -Np1 -d lge-kernel-star < patchname.patch
(replace patchname with name of the patch file)
Here, -N is for ignoring patches that seem to be already applied or reversed
p<num> Strip the smallest prefix containing num(here num=1) leading slashes from each file name found in the patch file
In this case, num=1 according to the path names in wkpark's patch, and in a lot of cases, the value of 1 is common
-d is to change to the directory immediately, before doing anything else
You need to apply wkpark's two patches one by one (0001-..., then bootloader-...)
If you get errors while patching, if they are basic errors like file not found etc. then you should manage to fix it yourself.
But if you get errors like "HUNK ... failed",
try
Code:
patch -Np1 --ignore-whitespace -d lge-kernel-star < patchname.patch
A "HUNK ignored" is ok, if patch was attempted previously, since that file might have been successfully patched last time
if a HUNK still fails, then read the troubleshooting guide
Setting RAM hack size (If you skipped the above patching step, dont do this)
wkpark's patch makes it possible for you to set ramhack size in kernel command line parameter.
The cmdline parameter has to have the full boot.img command line parameters, which you can obtain from dmesg. I have done it for you, so you can save time on that
Here's how it looks for the old bootloader: (for the new one, ignore this)
Code:
<5>[70:01:01 00:00:00.000] Kernel command line: loglevel=0 muic_state=1 CRC=10203036179a93 brdrev=1.0 uniqueid=37c7006421f6097 video=tegrafb console=ttyS0,115200n8 usbcore.old_scheme_first=1 tegraboot=sdmmc tegrapart=recovery:35e00:2800:800,linux:34700:1000:800,mbr:400:200:800,system:600:2bc00:800,cache:2c200:8000:800,misc:34200:400:800,userdata:38700:c0000:800 [email protected] vmalloc=128M androidboot.mode=normal androidboot.hardware=star androidboot.serialno=37c7006421f6097
Paste the line starting from loglevel=0 till the end (serialno) into .config file in lge-kernel-star folder in
CONFIG_CMDLINE="<here>"
Insert a carveout size in between vmalloc and androidboot.mode
Determing carveout size: carveout=<152 - RAM hack size>M
For example, if RAM hack size is 56, then carveout is 96M
So in that case, the cmdline is like this:
old bootloader:
Code:
CONFIG_CMDLINE="loglevel=0 muic_state=1 CRC=10203036179a93 brdrev=1.0 uniqueid=37c7006421f6097 video=tegrafb console=ttyS0,115200n8 usbcore.old_scheme_first=1 tegraboot=sdmmc tegrapart=recovery:35e00:2800:800,linux:34700:1000:800,mbr:400:200:800,system:600:2bc00:800,cache:2c200:8000:800,misc:34200:400:800,userdata:38700:c0000:800 [email protected] vmalloc=128M carveout=96M androidboot.mode=normal androidboot.hardware=star androidboot.serialno=37c7006421f6097"
new bootloader:
Code:
CONFIG_CMDLINE="tegraid=20.1.4.0.0 [email protected] carveout=152M android.commchip=0 vmalloc=128M androidboot.serialno=037c7006421f6097 video=tegrafb no_console_suspend=1 console=ttyS0,115200n8 debug_uartport=lsport,-3 androidboot.mode=normal usbcore.old_scheme_first=1 [email protected] [email protected] muic_state=0 tegraboot=sdmmc tegrapart=recovery:35e00:2800:800,boot:34700:1000:800,mbr:400:200:800,persist:600:2bc00:800,cache:2c200:7f00:800,misc:34200:400:800,userdata:38700:c0000:800,bcttable:0:600:800,bootloader:100:300:800,data/ve:f8800:1400:800,system:34c000:40000:800 "
and save the file
Dont set carveout too low, or else some gpu-intensive stuff may not work properly.
STEP 4: BUILDING THE KERNEL
In terminal,
Code:
cd ~/kernel/lge-kernel-star
Code:
make ARCH=arm CROSS_COMPILE=$CCOMPILER -j`grep 'processor' /proc/cpuinfo | wc -l`
This step may take a while, depending on your computer. Took ~5-10 mins for the first build for me, and ~1 min for the second build onwards.
If it asks in the terminal "use default config?" then say "y", if not, then ignore this
If you get some error and the building aborts within a few seconds, try the "Create environment variable part" again, and then return back directly to the build step.
After it is done, you should have a kernel stored in ~/kernel/lge-kernel-star/arch/arm/boot/zImage
Preparing the flashable zip for the kernel
Some compiled modules need to be included so that problems like wifi not switching on dont occur.
They are:
drivers/misc/bthid/bthid.ko
drivers/scsi/scsi_wait_scan.ko
drivers/net/wireless/bcm4329/wireless.ko
They will be used while preparing the flashable zip below.
Thanks to feav's compiled modules and benee's anykernel updater for star, all this is ready-made and you can simply:
Download the sample kernel zip attached below and replace /kernel/zImage and and the above modules in system/lib/modules/hw in that with yours, edit updater-script if you want.
Your flashable zip is now ready
STEP 5: FLASHING AND TESTING THE KERNEL
Put the sample kernel below as a backup in case your kernel does not boot and you need a working phone immediately.
Flash the kernel in recovery, wipe cache, dalvik cache and reboot.
If the phone goes past the LG logo screen(s) and into the bootscreen of the ROM, then it should work
Then you can check "kernel version" in settings->about phone to see your kernel information,
and you can see the new RAM size (which should be 342 MB + RAM hack size) in some app like battery dr saver, or antutu benchmark's system info.
If it doesnt work, make sure you have followed the entire guide properly and then ask queries
If you want to revert to another kernel, flash that kernel in recovery, or for stock kernel, flash your ROM.
Keeping kernel source up to date (for building again later after RC has made changes to the source):
Code:
cd ~/kernel/lge-kernel-star
git pull
This will update your source with the latest commits by RC. Then you can rebuild the kernel by doing the "create environment variable" and then skip directly to the build stage
Standard disclaimer:
I am not responsible if anything goes wrong with your phone or anything else.

Troubleshooting guide:
1. Patch failure
HUNK failed means that a particular file was not patched to some problem. In this case, a .rej file is saved in the same folder as the file to be patched, and it contains the stuff not patched.
Do not neglect "failed" hunk since it means a partially applied patch(some files patched, some files not), and may cause problems. "Ignored hunk" is ok, if the patch had been attempted before on a file and had succeeded on that file last time.
To manually patch the failed hunk, go that file where the hunk failed (has same name as .rej file without .rej extension)
For example, if .rej file is board-star.c.rej, and it contains the following sample lines (look for lines beginning with '+' and remove the + before adding, similar for -) go to board-star.c, and add the lines manually like this:
Code:
#if defined (CONFIG_STAR_REBOOT_MONITOR) || defined (CONFIG_BSSQ_REBOOT_MONITOR)
#define RAM_RESERVED_SIZE 100*1024
/* Force the reserved_buffer to be at its old (Froyo/GB) location
for reboot to work with the older bootloader */
if (strstr(saved_command_line, "brdrev=")) {
extern void *reserved_buffer;
pr_info("The older bootloader detected\n");
if (memblock_end_of_DRAM() > 0x17f80000) {
if (memblock_reserve(0x17f80000, RAM_RESERVED_SIZE)) {
pr_err("Fail to get reserved_buffer for the older bootloader\n");
} else {
pr_info("Change reserved_buffer for the older bootloader\n");
reserved_buffer = phys_to_virt(0x17f80000);
}
} else {
pr_info("Change reserved_buffer\n");
reserved_buffer = ioremap(0x17f80000, RAM_RESERVED_SIZE);
}
}
#endif
This was in the .rej file, and is to be added immediately after
Code:
#if defined(CONFIG_LGE_BROADCAST_TDMB)
star_dmb_init();
#endif /* CONFIG_LGE_BROADCAST */
in board-star.c (and before the next #if defined or closing bracket)
Similarly, the - lines to be deleted and + lines are to be added in that failed hunk file
(do this manual stuff only if hunk fails)
2. If ramhack kernel fails, but normal kernel works:
From your pc, in terminal do
adb shell dmesg > dmesg.txt
or from your phone, in android terminal emulator, do
dmesg > /sdcard/dmesg.txt
Copy it from your dmesg.txt starting from loglevel=0 till the end (serialno)
Look for a line in dmesg.txt which resembles this:
Code:
<5>[70:01:01 00:00:00.000] Kernel command line: loglevel=0 muic_state=1 CRC=10203036179a93 brdrev=1.0 uniqueid=37c7006421f6097 video=tegrafb console=ttyS0,115200n8 usbcore.old_scheme_first=1 tegraboot=sdmmc tegrapart=recovery:35e00:2800:800,linux:34700:1000:800,mbr:400:200:800,system:600:2bc00:800,cache:2c200:8000:800,misc:34200:400:800,userdata:38700:c0000:800 [email protected] vmalloc=128M androidboot.mode=normal androidboot.hardware=star androidboot.serialno=37c7006421f6097
Use your own phone's parameters instead of this and then set carveout size.
3. Problem with config file:
Pulling kernel config from device:
You need to retrieve a working kernel config from the device, and unzip it.
For that, connect your phone to your pc, enable USB debugging if it was disabled, and then in terminal
Code:
adb pull /proc/config.gz ~/kernel/lge-star-kernel-jellybean/config.gz
cat config.gz | gunzip > .config
Alternatively, you can pull the .config from the newest boot.img
Code:
scripts/extract-ikconfig boot.img > .config
Changes and updates:

There are always some things worth experiencing once in life, like if you are an Android user, building a ROM and a kernel. You have experienced it with your wonderful AF kernel, thats important

USB works fine, both adb and mass storage
This guide may seem intimidating, but trust me, once you complete it the first time, you'll find it really simple from the next build onwards.
Uploaded a slightly modified version of wkpark's 2nd patch (bootloader one) which may possibly fix one of the errors and may remove need for manually adding some lines. Updated link in OP and attached here too.
I tried the sample kernel and my camera stops functioning and so with other apps such as contacts, they don't start at all. Im on dec 20 nightly. Could it be the ramhack size? Maybe 32mb will suffice. Just saying.
Thanks to this, will probably try this next week..

Uploaded 32 MB ram hack kernel for those having problem with camera, try it out.
Download link 32MB RH
Update:
Added 24MB version too. Here you go:
24MB RH kernel
Thanks rugglez, 32 mb rh is ok so far, cm10 is way smoother and can still play nfs most wanted. Btw, can you apply the patch for double lg logo too by wkpark?
Sent from my P990-CM10
After installing the new kernel, if some apps still don't work or there any lag, disable "force gpu rendering" and "disable hardware overlays" in developer settings.
Thank you for your work! Just flashed the 32mb version without any problem. On cm7 the 48mb ramhack was the biggest without breaking 720p recording. Maybe you should give it a try!

Hi rugglez, got the ff. error when installing the required packages, Im on ubuntu 12.10 x64.
Note, selecting 'libsdl1.2-dev' instead of 'libsdl-dev'
Package sun-java6-jdk is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or

Can you install the dependencies from Raum's CM10 building thread here?
Follow steps 1 and 2 there.
Let me know if that works, ive updated the guide's step 1(setting up environment)
Installing the dependencies from this guide was the only thing i didnt test, since i had the CM10 environment set up already
a step is missing from this guide.
adb pull /proc/config.gz ~/kernel/lge-star-kernel-jellybean/config.gz

then

Just use "git clone git://github.com/CyanogenMod/lge-kernel-star.git", it should give you better download speed than for the zipped archive.
I synced the whole CM10 source tree on the remote buildbox in about 5-10 minutes - so github does provide great downspeed
@rugglez: You should add to the OP that you don't have to use adb to get the kernel config, it's already there
arch/arm/configs/cyanogenmod_p990_defconfig
Please refer to the old cm7 kernel how to by pastime: http://forum.xda-developers.com/showthread.php?t=1227241
I really like the fact that more and more building guides get posted here - and that more and more people are building their own ROMs and kernels these days.
After building (which already is a great start) many people even want to learn more about android development in general. That's the true xda spirit!
Kudos!
Hi, my name's Stefano I'm from Italy, and sorry for my poor english. This is the guide to build your own the KitKat (or whatever branch you want) for your HammerHead. We'll start, obviously, setting up your client (PC), and here we'll use ubuntu x64. Is possible to use almost any linux distribution (also MacOSX) but I prefer to stay on what is much supported and known (for me!). This guide is taken from internet and reading forums/blogs. I didn't invent anything, you can found a lot of guides like this. Just this is updated with last changes. For the setup part I read and paste a lot from here (thanks to sylentprofet).
Regard the hardware side you'll need at least of:
a Dual Core processor
4 Gb of RAM
80 Gb of hard disk for each repository (Better if SSD but don't required)
The Graphics Card don't care, we don't use to compile
A good internet connection, you have to download up to 40 Gb of stuff
A lot of patience, if you aren't go to download a ready ROM, it's better!
Time, time, time, time and again time!
How to Configure Ubuntu for Properly Compiling Android ROMs
This guide applies to Ubuntu 13.04 Raring Ringtail 64 bit (but also down to 12.04 LTS which is the version that I prefer). Do not use the 32 Bit version. Also, PAY CLOSE ATTENTION when to use “sudo” and when to not. It can make things funky if you do something as root that you shouldn’t. During normal build you don't have absolutely need to use "sudo", just during the PC setup.
Much thanks goes out to Google, ProTekk, Canonical, and everyone else that I read a random paragraph here and snippet there.
First, let’s set up the correct JDK.
Many of you probably have some kind of wrong Java installed. Sad cupcake.Let’s get rid of that. Copy and paste this into a Terminal window:
Code:
sudo apt-get purge openjdk-\* icedtea-\* icedtea6-\*
Back to the Terminal. Copypasta the following:
Code:
sudo add-apt-repository ppa:webupd8team/java
This will add the correct PPA to your system for updated builds of Java 6 JDK that are compatible with 13.04 (or less). No more unrecognized Java version errors! Yay! And it’s self updating, so you don’t have to redownload binaries everytime they release a new version.
Next, we actually need to install the package. More copypasta:
Code:
sudo apt-get update && sudo apt-get install oracle-java6-installer
Follow the onscreen instructions. You have to Accept the Licensing Agreement or whatever. Hopefully no human centipede clauses. Once that is completed successfully, you will have to restart any open browsers with Java content for it to display correctly.
To make sure the correct version of Java is activated, run the following at the Terminal prompt:
Code:
java -version
You should see something like the following:
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)
Ok, back to a fresh Terminal prompt. Time for installing the guts to build stuff in Ubuntu. Because (K)Ubuntu no longer carries ia32-libs-multiarch and ia32-libs (from Saucy onwards), it is necessary to install from precise repos:
Code:
sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu/ precise main restricted universe multiverse"
sudo apt-get update
sudo apt-get install ia32-libs-multiarch
once is installed, you can remove repository:
Code:
sudo add-apt-repository --remove "deb http://archive.ubuntu.com/ubuntu/ precise main restricted universe multiverse"
sudo apt-get update
Before start, install:
Code:
sudo apt-get install dpkg-dev
Code:
sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev zlib1g-dev:i386 libc6-dev lib32ncurses5-dev x11proto-core-dev libx11-dev:i386 libreadline6-dev:i386 lib32z-dev libgl1-mesa-glx:i386 libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc readline-common libreadline6-dev libreadline6 lib32readline-gplv2-dev libncurses5-dev lib32readline5 lib32readline6 libreadline-dev libreadline6-dev:i386 libreadline6:i386 bzip2 libbz2-dev libbz2-1.0 libghc-bzlib-dev lib32bz2-dev libsdl1.2-dev libesd0-dev squashfs-tools pngcrush schedtool libwxgtk2.8-dev python
And we wait. Don’t worry, this isn’t the crazy downloading part just yet.
When that is done, do this:
Code:
sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so
Now it's time to download and setup SDK Tools. First of all download Android SDK Tools for Linux x64. Extract the folder “sdk”, inside package, into your "Downloads" folder and rename it to "AndroidSDK" e.g..
Then come to your terminal and type:
Code:
cd ~/Downloads/AndroidSDK/tools
and after:
Code:
./android sdk
You can now see the GUI that propose all installable packages. Install Platform tools and Tools for most recent Android (4.4), with the most higher API (19+) version. Flag "accept" and install.
Once is complete, you have you need the binary for repo that will let you talk to git servers and download all that precious source code:
Code:
mkdir ~/bin
curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
Open "~/.bashrc" to add a line:
Code:
sudo nano ~/.bashrc
At the very bottom, add the following line:
Code:
export PATH=~/bin:$PATH
Save it. In nano that would be Ctrl-O and then Enter. Then Ctrl-X to exit back to a prompt. Type to restart bash:
Code:
source ~/.bashrc
Now you have all need to work (or play) with your ubuntu and it's time to give the sources (repositories) from your preferred Team (who share the source code for their rom). The most known host service for sources and projects is GitHub. E.g. https://github.com/CyanogenMod/
The point of start of any repo is its "manifest" (default.xml) where the team list all it's projects (here an example), only the necessary to the building process.
Until last year was necessary to compile (before begin and looking to platform manifest) an own local manifest where we exclude from download all the devices/kernel/vendor parts unnecessary for our device. This saves up to some Gigabytes of download.
Fortunately now the repositories will download itself the necessary devices/kernel/vendor parts when we'll choose ("lunch") the device to build ("make"). With the exception of AOKP who wanna know, before initialize your local repo, for which device/s you'd like build.
Now I'll write a section for each Team/ROM you want to initialize, that's for me has sense. How take a sense to put each "platform/project" in a different folder (e.g. CarbonDev in a folder and Cyanogenmod in another, both sons of your Home folder).
In the waiting to read next part, better familiarize a little with terms like "breakfast, brunch, lunch, make" into Android contest.
Building Cyanogenmod
In the terminal, now we'll make a folder where to store the Android source code. Typically will make it in your home folder, within a folder called like your projected ROM, to identify from other stuff, open your terminal and type:
Code:
mkdir –p ~/Cyanogenmod
cd ~/Cyanogenmod
Now we are going to initialize your local repository, with the "branch" cm-11.0 (KitKat), in your terminal:
Code:
repo init -u git://github.com/CyanogenMod/android.git -b cm-11.0
And now, the most long part of the story: you’re going to get the source. We have to download around 10-15 Gbytes. First of begin the process, you must to know that you can accelerate the process related to your processor and, obviously, to your internet band. You can choose the number of simultaneous processes to start. They depends from the "#" in the "-j" parameter. E.g. the option -j6 is related to a “normal” processor. If you have a performant processor and/or internet connection, try to increment putting –j10 or more. On terminal:
Code:
repo sync -j6
From time to time, check the situation on output, maybe occurs a pair of hours or a whole night. But when all will be done, you’re ready to build Android!
Once you finish your repo sync, you’ll ready to build. In your terminal, into your working folder type (pay attention at the initial “dot”):
Code:
. build/envsetup.sh
The commands are loaded, now you can build (tune your -j# parameter as you want):
Code:
breakfast hammerhead && make -j6 bacon
At the end of all, your fresh ROM to flash will be in Cyanogenmod/out/target/product/hammerhead. Happy flash!

There are a lot of people out there wondering how to build kernels. It sounds confusing and hard, but once you get the hang of it, it is actually quite easy. I got the jist of it in just a few practices. Now I give all of my information to you, in the simplest, most comprehensible and most noob friendly way I can. In this guide, I will be building the kernel for my phone, the Samsung Galaxy Victory 4G LTE. So make your adjustments where necessary.
What You Will Need:
A linux OS. I now use Ubuntu 14.04 Manjaro, and Manjaro or Arch are preferred. (Ubuntu is easiest)
Patience
(Optional) A boot.img for your device
Required files
Required Files:
Open terminal and paste the following (I assume you already have java and perl and all that jazz):
In Ubuntu/ Debian:
Code:
sudo apt-get install abootimg git-core gnupg flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev ia32-libs lib32z1-dev lib32ncurses5-dev gcc-multilib g++-multilib
For Arch/Manjaro, do
Code:
sudo pacman -S gcc git gnupg flex bison gperf sdl wxgtk squashfs-tools curl ncurses zlib schedtool perl-switch zip unzip libxslt python2-virtualenv bc
for 32 and 64 bit systems. For only 64 bit, add the following:
Code:
sudo pacman -S gcc-multilib lib32-zlib lib32-ncurses lib32-readline
Also, abootimg can be installed using
Code:
yaourt -S abootimg-git
For other distros, you may have to modify the command to get the required files, such as using yum
Also, make sure you have setup git and it is ready to go.
Setting Up Folders:
You are going to need a folder to build you kernel in. For this tutorial, I will use my setup: /home/nick/android/kernel/SPH-L300/Kernel. Kernel is the source directory that is made from the source zip and SPH-L300 I will also use a lot, which contains Kernel.
Downloading The Source:
Download the zip from http://opensource.samsung.com/ or from InsanelyCool's stock kernel source. Then I put it in the SPH-L300 folder. Afterwards, unzip it. You should have 2 files, Kernel.tar.gz and Platform.tar.gz. We are going to focus on Kernel.tar.gz, so unzip it. This will make the Kernel folder.
Now, in your terminal, cd to somewhere to keep your toolchains. I keep mine in ~/android/kernel.
Now type
Code:
git clone git://github.com/DooMLoRD/android_prebuilt_toolchains.git toolchains
for the toolchains I used. They should be put in the folder toolchains.
Modifying The Kernel:
Now is the time to modify the kernel. You can apply patches and change governors and frequencies etc here.
Applying a Patch:
The kernel version is 3.0.31. You can upgrade it using patches. Patches can be found here. You have to apply one patch at a time, which is why scripts come in handy when patching multiple times. I am going to show you how to upgrade to 3.0.33, since you can do that without error.
First, download patch-3.0.31-32.bz2 (or .gz) and download patch-3.0.32-33.bz2 (or .gz).
Extract both and move the extracted files into the Kernel source folder.
Cd to this folder in your terminal and type
Code:
patch -p1 < patch-3.0.31-32
. If you get something about
Code:
...assume -R? [n]
just press enter then press y then enter again.
Do the same steps for applying the other patch, just mod the command to work.
Building The Kernel:
Setting Up Environment:
In the Kernel source directory, open the file Makefile and press ctrl-f. Then enter CROSS_COMPILE, and look for CROSS_COMPILE = /xxxxx, where xxxxx is a directory. Change that directory to the toolchain of your choice. **Not all toolchains work!** For me, it would look like: CROSS_COMPILE = /home/nick/android/kernel/toolchains/arm-eabi-linaro-4.6.2/bin/arm-eabi- for Linaro 4.6.2. Save the file and exit.
Make sure your terminal is in the Kernel source directory.
Kernel Name:
If you want to change the kernel name, in terminal type
Code:
KBUILD_BUILD_VERSION="ROM NAME"
then
Code:
export KBUILD_BUILD_VERSION
.
Compiling It:
Next, type
Code:
export ARCH=arm
into terminal.
Almost there. The next step is to type
Code:
make gogh_defconfig
into terminal.
If you added options such as governors, do
Code:
make menuconfig
to activate them.
Otherwise, type
Code:
make -jx
where x is the number of processes per core. I use
-j2 for a dual core cpu. This takes about 20-30 mins for me. A quad-core Intel cpu takes 4 mins if you use -j5. For Intel, it is the # of cores + 1.
Actually Putting The Kernel Together:
Now that it has built, assuming you have had no errors and the terminal finishes with
Code:
Kernel: arch/arm/boot/zImage is ready
you are ready to assemble the kernel. Cd to outside your Kernel source to the folder that contains it. For me that would be SPH-L300. You are going to need a working boot.img for this phone to speed up this process by a lot. Whether its stock, mine, or Insanelycool's, just paste it into the folder.
In terminal, type
Code:
abootimg -x boot.img
Then
Code:
mkdir initrd && cd initrd && zcat ../initrd.img | cpio -i
And finally
Code:
find . | cpio -o -H newc | gzip > ../initrd.img
This splits the boot.img, and puts the ramdisk in the initrd folder.
Now, navigate to (kernel source)/arch/arm/boot and copy the zImage to where you were before (the SPH-L300 folder for me). When you paste, override the pre-existing zImage.
If you would like to change the splash screen before the bootanimation, swap out initlogo.rle in the initrd folder with the image of you choice. It must be a rle image and must be named initlogo to work. I won't tell you how to convert png's to rle's cuz I am sure you know how to Google.
Now, we actually but the boot.img together. In terminal, type
Code:
cd ../ && abootimg --create boot.img -k zImage -r initrd.img && abootimg --create boot.img -f bootimg.cfg -k zImage -r initrd.img
and make sure you are in the initrd folder. If you get the error updated is too big for Boot Image, use this command:
Code:
cd ../ && abootimg --create boot.img -k zImage -r initrd.img && abootimg --create boot.img -f bootimg.cfg -k zImage -c "bootsize=xxxxxx" -r initrd.img
and replace the x's with the size the kernel wants to be. This will give you a new boot.img in the containing folder (SPH-L300 for me). Now just zip it up and tell the updater-script where to flash it and voila!, you just made you own kernel.

There are a lot of people out there wondering how to build kernels. It sounds confusing and hard, but once you get the hang of it, it is actually quite easy. I got the jist of it in just a few practices. Now I give all of my information to you, in the simplest, most comprehensible and most noob friendly way I can. In this guide, I will be building the kernel for my phone, the Samsung Galaxy Victory 4G LTE. So make your adjustments where necessary.
What You Will Need:
A linux OS. I now use Ubuntu 14.04 Manjaro, and Manjaro or Arch are preferred. (Ubuntu is easiest)
Patience
(Optional) A boot.img for your device
Required files
Required Files:
Open terminal and paste the following (I assume you already have java and perl and all that jazz):
In Ubuntu/ Debian:
Code:
sudo apt-get install abootimg git-core gnupg flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev ia32-libs lib32z1-dev lib32ncurses5-dev gcc-multilib g++-multilib
For Arch/Manjaro, do
Code:
sudo pacman -S gcc git gnupg flex bison gperf sdl wxgtk squashfs-tools curl ncurses zlib schedtool perl-switch zip unzip libxslt python2-virtualenv bc
for 32 and 64 bit systems. For only 64 bit, add the following:
Code:
sudo pacman -S gcc-multilib lib32-zlib lib32-ncurses lib32-readline
Also, abootimg can be installed using
Code:
yaourt -S abootimg-git
For other distros, you may have to modify the command to get the required files, such as using yum
Also, make sure you have setup git and it is ready to go.
Setting Up Folders:
You are going to need a folder to build you kernel in. For this tutorial, I will use my setup: /home/nick/android/kernel/SPH-L300/Kernel. Kernel is the source directory that is made from the source zip and SPH-L300 I will also use a lot, which contains Kernel.
Downloading The Source:
Download the zip from http://opensource.samsung.com/ or from InsanelyCool's stock kernel source. Then I put it in the SPH-L300 folder. Afterwards, unzip it. You should have 2 files, Kernel.tar.gz and Platform.tar.gz. We are going to focus on Kernel.tar.gz, so unzip it. This will make the Kernel folder.
Now, in your terminal, cd to somewhere to keep your toolchains. I keep mine in ~/android/kernel.
Now type
Code:
git clone git://github.com/DooMLoRD/android_prebuilt_toolchains.git toolchains
for the toolchains I used. They should be put in the folder toolchains.
Modifying The Kernel:
Now is the time to modify the kernel. You can apply patches and change governors and frequencies etc here.
Applying a Patch:
The kernel version is 3.0.31. You can upgrade it using patches. Patches can be found here. You have to apply one patch at a time, which is why scripts come in handy when patching multiple times. I am going to show you how to upgrade to 3.0.33, since you can do that without error.
First, download patch-3.0.31-32.bz2 (or .gz) and download patch-3.0.32-33.bz2 (or .gz).
Extract both and move the extracted files into the Kernel source folder.
Cd to this folder in your terminal and type
Code:
patch -p1 < patch-3.0.31-32
. If you get something about
Code:
...assume -R? [n]
just press enter then press y then enter again.
Do the same steps for applying the other patch, just mod the command to work.
Building The Kernel:
Setting Up Environment:
In the Kernel source directory, open the file Makefile and press ctrl-f. Then enter CROSS_COMPILE, and look for CROSS_COMPILE = /xxxxx, where xxxxx is a directory. Change that directory to the toolchain of your choice. **Not all toolchains work!** For me, it would look like: CROSS_COMPILE = /home/nick/android/kernel/toolchains/arm-eabi-linaro-4.6.2/bin/arm-eabi- for Linaro 4.6.2. Save the file and exit.
Make sure your terminal is in the Kernel source directory.
Kernel Name:
If you want to change the kernel name, in terminal type
Code:
KBUILD_BUILD_VERSION="ROM NAME"
then
Code:
export KBUILD_BUILD_VERSION
.
Compiling It:
Next, type
Code:
export ARCH=arm
into terminal.
Almost there. The next step is to type
Code:
make gogh_defconfig
into terminal.
If you added options such as governors, do
Code:
make menuconfig
to activate them.
Otherwise, type
Code:
make -jx
where x is the number of processes per core. I use
-j2 for a dual core cpu. This takes about 20-30 mins for me. A quad-core Intel cpu takes 4 mins if you use -j5. For Intel, it is the # of cores + 1.
Actually Putting The Kernel Together:
Now that it has built, assuming you have had no errors and the terminal finishes with
Code:
Kernel: arch/arm/boot/zImage is ready
you are ready to assemble the kernel. Cd to outside your Kernel source to the folder that contains it. For me that would be SPH-L300. You are going to need a working boot.img for this phone to speed up this process by a lot. Whether its stock, mine, or Insanelycool's, just paste it into the folder.
In terminal, type
Code:
abootimg -x boot.img
Then
Code:
mkdir initrd && cd initrd && zcat ../initrd.img | cpio -i
And finally
Code:
find . | cpio -o -H newc | gzip > ../initrd.img
This splits the boot.img, and puts the ramdisk in the initrd folder.
Now, navigate to (kernel source)/arch/arm/boot and copy the zImage to where you were before (the SPH-L300 folder for me). When you paste, override the pre-existing zImage.
If you would like to change the splash screen before the bootanimation, swap out initlogo.rle in the initrd folder with the image of you choice. It must be a rle image and must be named initlogo to work. I won't tell you how to convert png's to rle's cuz I am sure you know how to Google.
Now, we actually but the boot.img together. In terminal, type
Code:
cd ../ && abootimg --create boot.img -k zImage -r initrd.img && abootimg --create boot.img -f bootimg.cfg -k zImage -r initrd.img
and make sure you are in the initrd folder. If you get the error updated is too big for Boot Image, use this command:
Code:
cd ../ && abootimg --create boot.img -k zImage -r initrd.img && abootimg --create boot.img -f bootimg.cfg -k zImage -c "bootsize=xxxxxx" -r initrd.img
and replace the x's with the size the kernel wants to be. This will give you a new boot.img in the containing folder (SPH-L300 for me). Now just zip it up and tell the updater-script where to flash it and voila!, you just made you own kernel.

it's not noob friendly. how do i know about other stuff that required for compiling?
Thank's for this tutorial. I have a Unbuntu box with 4Gig RAM and I'm interested in trying this out. Would that be sufficient for compiling android or should I upgrade my machine first?
Hello,
I'm compiling this kernel https://github.com/MiCode/Xiaomi_Kernel_OpenSource/tree/ido-l-oss
But the kernel stop booting as it doesn't found a sound card.
Running ls /dev/snd return only timer while it will have some pcm and other device in stock kernel.
Can somebody point me where to look at?
Thanks
