Hey all, I did a quick search but couldn't find an answer:

I'm back to using an N900 so I flashed to 1.3, and now installed CSSU per https://wiki.maemo.org/CSSU BUT I accidentally first installed "testing". I couldn't uninstall cssu so I figured I would install "stable" afterwards. Have I missed it up? Do I need to reflash my phone to actually obtain a "stable" version of cssu?
