Thank you for the help. Unfortunately that tool is no use to me.

I didn'd do the backup with PC Suite/Ovi Suite... Mine was done with Maemo's Built-in backup tool (the one with a safebox icon)

I've attached an image of the files I've got.

What happened to my N900 is that it got wt. I tried drying, the rice technique etc but nothing. I got it to turn on, but the touchscreen wouldn't recognize any touching...
