https://www.turris.cz/doc/en/howto/omnia_factory_reset

 Available reset modes:

    1 LED: Standard (re)boot
    2 LEDs: Rollback to latest snapshot
    3 LEDs: Rollback to factory reset
    4 LEDs: Re-flash router from flash drive
    5 LEDs or more: Boot to rescue shell

Debian

root@turris:/mnt/tmp# wget http://aule.elfove.cz/~brill/omnia-debian/omnia-medkit-20170330.tar.gz

# boot into rescue mode

root@(none):~# mount /dev/mmcblk0p1 /target/

root@(none):~# btrfs subvolume create /target/@debian

watchdog will timeout, but you will eventually have subvolume visible from u-boot (which is not case if you just create subvolume from Turris OS

root@turris:/# btrfs sub create @debian
Create subvolume './@debian'

root@turris:/# cd /@debian
root@turris:/@debian# tar xf /mnt/tmp/omnia-medkit-20170330.tar.gz
