this kitchen is showing you the problem. that's one of many benefits.
import metadata package from the same build you want to cook in.
then edit/reorder packages.sof/cif with built in editors.
if you don't have cooking experience, you better start off with a stock rom.
this kitchen doesn't make you a experienced chef. you have to learn with it and gain experience.
the best practice for me was to build hybrid roms for the x1i with packets from hd2 (was not released yet at the given time).
i saw so many errors myself and flashed my devices hundreds of times.
i like to share my experiences with everyone. feel free to ask if you have any questions.
but remember:
if you have problems, they are caused by your work in the kitchen and not the kitchen itself.
don't blame the kitchen for errors first. my rom is working very well (many others are successfully using it too).
btw:
when i ported my evk/prb based kitchen to osbuilder structure, osbuilder was showing me dozens of problems that i had to fix (evk showed no problems at all).
it's always better to know the problems and to fix them. i don't really like the fact that they where simply ignored by prb-based kitchens.
