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 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):
  

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

• 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)
  

  # 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
  

• then we need to compute the md5sums:
  

  ./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
  

• write down the result of both md5sum commands
• download the nandroid.md5 file
  

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

• change the lines where there is boot.img and system.img to the ones you've written down previously
• push them:
  

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

• unmount the sdcard
  

  # ./adb shell
  umount /sdcard
  

• 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:
  

  # ./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
  

• 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):
  

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

• then reboot:
  

  # ./adb shell
  reboot
