Good luck, as long as you're not running windows 64-bit you should be able to flash new rootfs with BackupMenu installed and get your data safely without booting livecd = instructions like "click start;click run;type cmd and press enter...", based on your posts, language/tech barrier should be non-existant.

@Elena P: I replied you via e-mail. I still think it is better to join #maemo for step-by-step instructions than searching for a native speaker on russian forums.Your English is pretty ok and instructions you will need to follow are not complicated.

Thank you all, for your advice and responses - the problem has been sorted out!
