h2. Introduction

Here's a tutorial that covers the installation of a previously built or downloaded Free Android Image,we will assume that: 

* you don't have the engineering bootloader

* you have root access

* you have a blank vfat sdcard in your android phone with enough free space

h2. Howto

* /!\ first backup your current version...in case something is wrong we need it

* then if you want the proprietary wifi firmware,execute the following command on your computer(/!\ the firmware is proprietary,we don't know what it does and we are not even allowed to redistribute it):

<pre>

# ./adb pull /system/etc/wifi/Fw1251r1c.bin ./

</pre>

* download an image that can flash our Free Android, like cm-recovery-1.4.img for instance (/!\ we didn't check cm-recovery-1.4.img's freedom) 

<pre>

# wget http://n0rp.chemlab.org/android/cm-recovery-1.4.img

</pre>

Then we will boot on the image that will flash our android:

* shutdown your phone if it isn't shut down

* press the camera button first,keep pressing it while pressing the power button...that will give you a screen with skateboarders

* use fastboot to boot:

<pre>

# ./fastboot boot cm-recovery-1.4.img

</pre>

* press on the back button(<-) that is under the menu button at the right of the trackball

it will boot

* backup your image selecting "nandroid v2.2 backup"

* then use adb to push your images but first we need to look where to push them:

<pre>

./adb shell

# mount -t vfat /dev/block/mmcblk0p1 /sdcard

# ls -d /sdcard/nandroid/*/*                   

/sdcard/nandroid/HT935NG03334/CBDMRS12-20090917-1455

# exit

</pre>

* write down the last line before the exit command,because it will differ from device to device

* push the images:

<pre>

# ./adb shell

# mount -t vfat /dev/block/mmcblk0p1 /sdcard

# exit

# ./adb push boot.img /sdcard/nandroid/HT935NG03334/CBDMRS12-20090917-1455

# ./adb push system.img /sdcard/nandroid/HT935NG03334/CBDMRS12-20090917-1455

</pre>

* then we need to compute the md5sums:

<pre>

./adb shell

# md5sum /sdcard/nandroid/HT935NG03334/CBDMRS12-20090917-1455/boot.img 

a491db2000489c7fb7c5f7fe4b103b8c  boot.img

# md5sum /sdcard/nandroid/HT935NG03334/CBDMRS12-20090917-1455/system.img 

610b10a715ea1a5db4e6badd6a8a2989  system.img

</pre>

* write down the result of both md5sum commands

* download the nandroid.md5 file

<pre>

# ./adb pull /sdcard/nandroid/HT935NG03334/CBDMRS12-20090917-1455/nandroid.md5 ./

</pre>

* change the lines where there is boot.img and system.img to the ones you've written down previously

* push them:

<pre>

# ./adb push nandroid.md5 /sdcard/nandroid/HT935NG03936/CBDMRS12-20090917-1455/nandroid.md5 

</pre>

* unmount the sdcard

<pre>

# ./adb shell

umount /sdcard

</pre>

* then select "restore the latest backup" on the screen,with the trackball

* press home like it is said

* then select "wipe  data/factory reset" on the screen,with the trackball /!\ it will erase all the data of your phone...

* then select reboot system now

* wait for the system to boot(the boot will take longer than usual)

* then do the following:

<pre>

# ./adb shell

# cd /data/data/com.android.providers.settings/databases

# sqlite3 settings.db

SQLite version 3.5.9

Enter ".help" for instructions

sqlite> INSERT INTO secure (name, value) VALUES ('device_provisioned', 1);      

sqlite> .exit

</pre>

* then if you want the proprietary wifi firmware,execute do the following: (/!\ the firmware is proprietary,we don't know what it does and we are not even allowed to redistribute it): 

<pre>

# ./adb remount

# ./adb push Fw1251r1c.bin /system/etc/wifi/

</pre>

* then reboot:

<pre>

# ./adb shell

reboot

</pre>
