WARNING: Ubuntu and some other distributions, auto-mount the media when inserted. This can cause inconsistency and errors! You can umount all using: umount /dev/sdX*

1. Download the selected image (Android/Ubuntu/...).
2. Unpack it. (If its a .xz extension you can use xz -d image.img.xz on cmd line).
3. A good step is always to clear your destination media first! dd if=/dev/zero of=/dev/sdX bs=4M
4. Flash your image: sudo dd if=image.img of=/dev/sdX bs=4M
5. Always type sync before removing the media to make sure that all data is written.
