Hello all.
My n900 started to have some segfaults and became almost unusable. I couldn't make a backup but had some older backups from backup menu.
I reflashed it, and when I saw the difference in speed (I just enjoy it again, it seems so fast) I deciced to not restore the complete backup of my old (and probably quite messed up) system. I had no problem to restore my gpe calendar, installed again all what I need, but I don't manage to manualy restore my contacts bookmarks and conversations from the backup files on my computer.
I used the manual restore page, and tried to replace the osso-abook, osso-abook-backup bookmarks and rtcom-eventlogger by two means:

• ssh: I'm supposed to kill the apps (tried killall osso-abook and other things not sure of the correct commands), but even after a restart, I have no conversations, no bookmarks, and the adress book has a spinning wheel for ever with no contacts appearing
• backup menu: I started a USB connection with read-write, on my computer I had to use sudo to copy the files, and I suppose there is a problem with the owner/permissions of the files. Anyway, contacts close with internal error, no conversations...

Can anybody help me please ?

Your case sounds vaguely similar to mine. I reflashed a phone and selectively copied address book, calendar, rtcomm and messaging log etc (including some game results) from the old one. Except I didn't do my homework properly which means I wasn't aware of the restore page and had to reinvent the wheel on my own.

I used scp for the job. On the "old" device, run e.g.
That did one half of the job. The other half was restarting the affected processes. Since I had a few of them I just did a reboot.

One funny thing, I had to manually merge my Skype contacts again with my main contacts. No idea why.
