== 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

== Howto ==

 * /!\ first backup your curent 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):

{{{

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

}}}

 * dowload 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) 

{{{

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

}}}

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:

{{{

./fastboot boot cm-recovery-1.4.img

}}}

 * 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:

{{{

./adb shell

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

ls -d /sdcard/nandroid/*/*                   

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

exit

}}}

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

 * push the images:

{{{

./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

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

}}}

 * then we need to compute the md5sums:

{{{

./adb shell

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

a491db2000489c7fb7c5f7fe4b103b8c  boot.img

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

610b10a715ea1a5db4e6badd6a8a2989  system.img

}}}

 * write down the result of both md5sum commands
