The folks at Kano make it easy to download and reinstall the Kano OS via a burner program available for Windows and Mac. For those of us with Linux boxes, the process is easy enough to do by hand.
Download the appropriate version of the latest Kano OS from the Kanux Public Build download area. If you aren’t sure what file you want, keep in mind:
- You probably want the most recent release. The more recent the release, the higher the number. Release 2.1.0 is more recent than 2.0.1.
- You probably want the largest version that will fit on your SD card. Each release comes in two sizes: an 8 GB version (which is indicated as such) and a 4 GB version (which has no size indication). I use the 8 GB SD card that came with our Kano, so I download the 8 GB version.
- Each release comes in a .gz and .zip version. Choose whichever compression scheme you prefer.
Decompress the file you downloaded, for example:

You will now have the Kano OS image file. For example, after decompressing the above I had Kanux-Beta-v2.1.0-release-8gb.img.
Insert your SD card into your computer and delete all partitions from it. This can be done from the terminal, or you can use a GUI tool such as gparted. Determine the device path of the SD card as mounted on your computer. Again, either the terminal or gparted can tell you this. For example, on my hardware the SD card is /dev/sdb.

Write the image to the SD card with a command of the form:
This command will take a few minutes to complete, and no output to the terminal will appear in the meantime. Patience is a virtue. A successfully completed write will look something like:
Remove the card from your Linux box, insert it in your powered-off Kano, fire it up, and you’re done.
