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!
