From the N900 Imaging machine, run

cd ~/n900-imaging
sudo ./flash.py

Once the flashing script shows 'Done! Unplug device',

1. unplug the device. The screen will stay black with dots in the center.
2. Remove and replace the battery and replace the back plate.

4. The device will start up on battery insertion.
5. 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.

7. When a grid of programs shows up, scroll down until you see "X Terminal" and tap that icon.

• In the terminal run:

sudo initialize $num

• where $num is the number in the N900 hostname. For instance 'n900-001' would be initialized with the command:

sudo initialize 001

sudo reboot

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.
