WARNING: Flashing MeeGo to your N900 will permanently erase your settings and may cause damage to your device. This image is meant for experienced developers only. With the open image the battery management is not functional so you may cause damage to your device. We do not take any responsibility of the damage that may be caused to your device.

Preparations before flashing

• Get the flasher tool from http://tablets-dev.nokia.com/maemo-dev-env-downloads.php
• Get the MeeGo image and also the kernel by following the instructions from Meego N900 images page. You can also create your own image. See creating arm image with MeeGo Image Creator for instructions.
• Ensure that battery in your N900 is fully charged.
• Unplug the charger and turn the device off.

Installing MeeGo image

1. Remove the battery from the device.

2. Connect the device to computer with USB cable.

3. Next start the flasher software:

sudo flasher-3.5 -f -k <kernel_image> -r <meego.ubiimg> 

4. Put the battery back to the device.

5. If the flasher does not recognize the device go back to step 2.

After the flashing is complete power off the device by removing the battery and go to step 7 in case you are not using the closed Nokia binaries.

6. (Optional: For image without closed components): You need to also disable watchdogs if you are not using the closed components, especially the Battery Management Entity (BME). This can be done similarly to above, except the flasher command is following:

sudo flasher-3.5 --enable-rd-mode --set-rd-flags=no-omap-wd,no-ext-wd

7. After these steps you can remove the USB cable and put the battery back to the device. The device should boot to xterm with MeeGo codedrop image.
