geekgirl74,

Don't install things that require inception via MeeCatalog... Since you are in open mode, you don't even need inception to install those toggles or power-menu.

For the former, use N9QTweak with the open mode option for Tweak T while for the latter the thread has open mode instructions too which are much easier

N9QTweak has a comprehensive PDF/Wiki (latter should be updated today due to migration) for your reference so do some reading and you are good to go.

If you get a new N900 try out CSSU-Thumb; it speeds up things drastically
