Preparations before flashing

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

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.
