HOWTO: Build and Flash Motorola's kernel from source

DISCLAIMER:
I'm not responsible for any damages done to your phone. Please read carefully, and also please, please do a nandroid backup.
If any of the following fails, don't continue. And post your errors on this thread.

Prepare your system

Code:

$ sudo apt-get install git-core gnupg sun-java5-jdk flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev

Get the Kernel sources for your device from https://opensource.motorola.com/sf/g...s.cliqdext/frs
Be sure to download the one for your CLIQ/DEXT, if you compile other than the one intended for your device you will be left in 1969!! (DISCO!).

Note: The latest for TMO, is split in 3 files, download all of them.

Once you have downloaded all your files

Code:

$ mkdir ~/motorola-source
$ gunzip morrison-customer-tmo-1_4-release-1_4_8-framework.tar.gz
$ tar xvf morrison-customer-tmo-1_4-release-1_4_8-framework.tar -C ~/motorola-source
$ gunzip morrison-customer-tmo-1_4-release-1_4_8-external.tar.gz
$ tar xvf morrison-customer-tmo-1_4-release-1_4_8-external.tar -C ~/motorola-source
$ gunzip morrison-customer-tmo-1_4-release-1_4_8-kernel.tar.gz
$ tar xvf morrison-customer-tmo-1_4-release-1_4_8-kernel.tar -C ~/motorola-source

This should leave a directory structure like this under ~/motorola-source

Code:

$ ls ~/motorola-source
base bionic bootable build dalvik external frameworks kernel libhardware libhardware_legacy Makefile msm7k out prebuilt README.txt system unpack.pl vendor

Now lets get the prerequisites stated at ~/motorola-source/README.txt

Once you have downloaded all of previous requirements you will need to download several things from android to do this:

Code:

$ mkdir ~/moto-prerquisites
$ cd ~/moto-prerquisites
$ git clone git://android.git.kernel.org/platform/frameworks/base.git
$ git clone git://android.git.kernel.org/platform/hardware/libhardware.git
$ git clone git://android.git.kernel.org/platform/hardware/libhardware_legacy.git
$ git clone git://android.git.kernel.org/platform/hardware/msm7k.git
$ git clone git://android.git.kernel.org/platform/prebuilt.git

Get ready to wait a while because de prebuilt repository is quite big
Once all of the above have finished lets set the prerequisites to the TAGS specified in the README.txt

Code:

$ cd ~/moto-prerquisites/base
$ git checkout android-1.5r3

$ cd ~/moto-prerquisites/libhardware
$ git checkout android-1.5r3

$ cd ~/moto-prerquisites/libhardware_legacy
$ git checkout android-1.5r3

$ cd ~/moto-prerquisites/msm7k
$ git checkout android-1.6_r1

$ cd ~/moto-prerquisites/prebuilt
$ git checkout android-1.5r3

Once you've done this copy all the directories to ~/motorola-source

Code:

$ cp -r base libhardware libhardware_legacy msm7k prebuilt ~/motorola-source

Now we have to unpack what comes in the sources from motorola

Code:

$ cd ~/motorola-source
$ chmod +x unpack.pl
$ ./unpack.pl

Now you have everything that's needed to compile your kernel
You have to set some variables first

Code:

$ export PLATFORM_DIR=~/motorola/source
$ export ARCH=arm
$ export CROSS_COMPILE=arm-eabi-
$ export PATH=/prebuilt/linux-x86/toolchain/arm-eabi-4.2.1/bin:

Now lets build
Code:

cd /kernel
$ make msm_mot_defconfig

This line will build the kernel and output a zImage
Code:

$ make ANDROID_BUILD_TOP=

This will build the wireless driver module dhd.ko
Code:

$ make -C /system/wlan/bcm/osrc/open-src/src/dhd/linux ANDROID_BUILD_TOP=

Now you have build your kernel!
results should be
Code:

~/motorola-source/kernel/arch/arm/boot/zImage
~/motorola-source/system/wlan/bcm/osrc/open-src/src/dhd/linux/dhd.ko

In order to flash this to your system you will need
A nandroid backup and unpack-bootimg.pl and repack-bootimg.pl get them from here http://android-dls.com/wiki/index.ph...ck_Boot_Images

Code:

$ mkdir ~/bin
$ unzip unpack-bootimg.zip -d ~/bin
$ unzip repack-bootimg.zip -d ~/bin
$ export PATH=:~/bin

With your nandroid backup search for your boot.img and copy it somewhere easy to find

Code:

$ mkdir ~/mymoto
$ cd ~/mymoto
$ cp /path/to/my/nandroid/boot.img .

Extract the boot image
Code:

$ unpack-bootimg.pl boot.img

this will leave you with
Code:

$ ls ~/mymoto
boot.img boot.img-kernel.gz boot.img-ramdisk boot.img-ramdisk.cpio.gz

Now lets repack that boot image with our new kernel

Code:

$ cd ~/mymoto
$ repack-bootimg.pl ~/motorola-source/kernel/arch/arm/boot/zImage boot.img-ramdisk my-boot.img

//You'll need android-sdk installed to use adb search the forums on how to install android-sdk
Now push your image and wireless driver to your phone
Code:

$ adb push my-boot.img /sdcard/
$ adb push ~/motorola-source/system/wlan/bcm/osrc/open-src/src/dhd/linux/dhd.ko /system/lib/
$ adb shell

Now let's see where we should flash our image
Code:

# cat /proc/mtd
dev: size erasesize name
mtd0: 00300000 00020000 "boot"
mtd1: 08ac0000 00020000 "system"
mtd2: 0df80000 00020000 "userdata"
mtd3: 00040000 00020000 "misc"
mtd4: 00500000 00020000 "recovery"
mtd5: 06000000 00020000 "cache"
mtd6: 00080000 00020000 "splash"

As we can see mtd0 is where our boot image is stored, be sure to checkout wich one corresponds to your phone but it should be the same for all

now erase /dev/mtd/mtd0
Code:

# cat /dev/zero > /dev/mtd/mtd0
write: No space left on device [this is ok, you can ignore]
# flash_image boot /sdcard/my-boot.img
# reboot

That's it now you have built and flashed your newly built kernel!
