It will take you about 5 minutes to run out of space on the internal 256 MB of flash provided on the Nokia n800 so moving your Operating System to a flash card is a good idea. It's our goal is to install the latest Diablo firmware, install the bootmenu and then move the OS to flash.


Install Diablo firmware
  1. Download the flasher for Linux and tablet model from Nokia's Tablet Dev site
  2. In the same directory download the latest firmware image
  3. Make sure the battery of your tablet is fully charged.
  4. Unplug charger and switch off the tablet.
  5. Connect the tablet to your computer via USB without turning it on.

Execute as root and replace with the firmware image you downloaded from Nokia:

For the N800 and N810:

./flasher-3.0 -F RX-34_DIABLO_5.2008.43-7_PR_COMBINED_MR0_ARM.bin -f -R

You should now see Suitable USB device not found, waiting, switch on your tablet while holding the Home-button (N800) or swap button (N810), and watch the messages on your console as the FIASCO image is flashed, after which it will reboot automatically—you're done!

Now we need to install a couple of files to get us our boot menu and then to move the OS to flash.

Move Diablo to flash and install boot menu

Before we get too carried away adding buggy software to Diablo (you know you will) we'll move it to flash and we can add the buggy software. This way when it stops working and we need to fix it but don't have time we can just reboot in the stock Diablo firmware.

This tutorial will delete all information on your SD memory card! Install only one SD card into the system, if there are two it won't work.

  1. Using the web browser on the Tablet browse to
  2. Click on Install Tools and select Save Target As.. and save it to Documents
  3. Open Application Manager, Select Install from File menu and select the Install Tools file
  4. After it's done installing the reboot and choose Boot from Flash from the boot menu
You now have Diablo running off of Flash
