Execute the flashing script:
On any GNU/Linux distribution, make sure that you have “fastboot” installed from your package management system, and execute the flashing script by typing “sh flash-for-unix.sh”. If you have not installed “fastboot” using the distribution package management system, you need to prefix the command above with “sudo”.
- Even if you had fastboot installed from your package management system, you need the sudo prefix. (For me on Ubuntu 18.04 LTS, too.)
- The navigation to the folder an console should be mentioned. So newbies could find help with an internet search.
Thanks for all efforts und kindest regards
