Imaging Steps

Launch the OS X Terminal then do the following

  • On the imaging computer, run:
cd ~/n900-imaging
sudo ./flash.py
  • Follow the steps in the script started above (flash.py)
  • wait for the script to say 'Done! Unplug device'
  • unplug the device. The screen will stay black with dots in the center.
  • Remove and replace the battery and replace the back plate.
  • Ensure that the camera shutter is closed.
  • The device will start up on battery insertion.
  • Once you see a prompt that says "Your Nokia N900 has the following settings" press the "save" button.
    • The screen will change to dots in the center of a black screen while the device finishes setup.
  • Once the background of the device changes to a picture of a water stream. Start up the terminal by pressing the 2x3 grid of squares in the top left corner of the screen.
  • When a grid of programs shows up, scroll down until you see "X Terminal" and tap that icon.
  • In the X Terminal run (substituting $num for the zero-padded host number, n900-001 becomes 001)
sudo initialize $num
  • Once this command has completed, plug it into the charger in its final location and run the command:
sudo reboot
  • leave the keyboard slider open

At this point, the device is set up and will go into staging automatically.

Machine Setup

THIS SECTION IS FOR SETTING UP A NEW IMAGING MACHINE The rest of the document is not applicable for flashing.

To make this go quicker, you can set up your MacBook (or any mac) to be a flashing computer.

Start by setting up the required Mozilla written tools

cd ~ #or wherever you want to work from
hg clone http://hg.mozilla.org/build/tools
ln -s tools/buildfarm/mobile/n900-imaging

At this point you need to obtain the following files:

  • moz-n900-vNN.ubi - mozilla custom firmware
  • RX-51_2009SE_1.2009.41-1.VANILLA_PR_EMMC_MR0_ARM.bin
  • RX-51_2009SE_2.2009.51-1_PR_COMBINED_MR0_ARM.bin

The easiest way is to run

scp maemo@mobile-image02.build.mozilla.org:n900-imaging/moz-n900-*.ubi .
scp maemo@mobile-image02.build.mozilla.org:n900-imaging/RX-51*.bin .

Finally, you need the Mac OS X version of the flasher-3.5 program. Download 'maemo_flasher-3.5_2.5.2.2_i386.dmg' from here(live link doesn't work). Next you will need to obtain.
