hehe, that bricked the device. (: probably I had to disable ssu repo before doing that.
How it happened.
apt-get remove of the package brought also new packages, I guess from the diablo ssu, inculding kernel flasher. After, the system does not boot.

on other device I have tried to remove only osso-pdf-viewes with dpkg -r --force. Then I have disabled ssu repo, and tried to update osso-pdf-viewer, but it seems that there is no more recent version than which I have.
