Well, once tablets-dev.nokia isnt going back anytime soon (I guess) I tried to fix my DrLaunch problem:

My step by step was:

1)Install DrLaunch
2)Start terminal
3)sudo gainroot
4)cd ..
5)cd ..
6)find . -name *drlaunch* | xargs rm -rf
7)dpkg --configure -a
8)Install drlaunch again

Sounded like it didn't work. Then, in my next reboot, voilá! DrLaunch appeared in my screen out of nowhere.

I don't know if was this that worked or if in the meantime DrLaunch was updated, but anyway, at least for now, now I don't have to flash.
