my conversations inbox widget, hermes, callnotify, tweakr does not work for me

i have no idea how to change this

ive been lookin up xterm and apt-get upgrade/update
doesnt seem to work for me, i have been getting errors

should i reflash my n900? i heard there is a certain to do it or it will crash my n900 or something?

any pointers guys, im really desperate for getting my phone back to the way it was thanks!
