Thanks for the info you provide.
My phone (with Leshak's Kitchen 2 ROM) has been unstable and recently crashed completely (I can get to recovery though). I want to update it with a newer stable (!!!) ROM, so am looking at your instructions. But in your link to the SpicaGenMod download there is a post referring to a SpicaGenMod kitchen. Can I just use that instead of going through all the steps you suggest?
