Oh yes, mistake - but on my side, forgot the " on the end. Thanks for your time, man.

So, I boot RescueOS, use file script with mount-maemo-root.sh, but when I than write poweroff command, the maemo wouldn't boot, and the situation with Cold Flash is the same. Also I tried flash Vanilla and Fiasco, but nothing which made my n900 bootable Maemo OS.
