Using Linux Flasher

The flasher is a command line tool which you can use to flash items to your Nokia Internet Tablet. You can download the utility from: this location. Be careful to select the right flasher from the page. Different Internet Tablet products may require a spesific flasher-tool.

You should save the flasher tool to the directory you wish to use as the working directory. After you have saved the tool, go to the directory and change the file to executable with chmod.

$ chmod +x flasher

To run the flasher you need root-user rights. As a root use type:

Here you see all the necessary parameters and information which are enabled for use in the flasher.

To try out the flasher, download the reference root filesystem for your spesific product. See details in the releases page where to find the reference root filesystem that is suitable to your product.

Save the rootfs to the same directory which includes the flasher tool and complete the following steps:

  • Make sure you are the root user on your PC
  • Turn off the Nokia Internet Tablet
  • Make sure your device is connected to your PC via USB
The Flasher tool does not work through an USB hub.

After these steps your device is ready to receive the root filesystem. Issue the following command:

$ ./flasher -r Maemo_Dev_Platform_rootfs.jffs2 -f -R

After this command, turn on the device, and the flashing will start.

If everything goes well you should see a progress bar in the bottom of the device screen.

The name of the root filesystem may vary.

The command above will flash the new root filesystem to your device. When the flashing is complete the device will reboot.
