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. Improper use or installation of the image may harm your device. With the open image, the battery management is not functional, so you may cause damage to your device. We do not take any responsibility for the damage that may be caused to your device.'

Preparations before flashing

NOTE: THIS INSTALLATION METHOD IS NOT SUPPORTED WITH THE CURRENT MEEGO RELEASES

• Get the flasher tool
• 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.
• Make sure that the 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 your computer with a USB cable.
3. Next, start the flasher software:

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

4. Put the battery back into the device.
5. If the flasher does not recognize the device, go back to step 1. After the flashing is complete, power off the device by removing the battery and go to step 7, in case you are using the closed Nokia binaries.
6. (Optional: For an image without closed components): You also need to 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 the 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.
