i think with the rom manager it has a fix permisiion button so you dont have to wipe anymore i beliueve. i may be wrong though .I agree about his team or whatever. Blackdroid seems like a nice guy but a couple of his team members bullying on the forums has really turned me off reading UD threads.
I'd like to check out Koush's work myself. did you use ROM Manager and do a full wipe?
You should still do a full wipe coming from another ROM or if you're 5.0.5.4 or earlier and updating to 5.0.5.6 or 5.0.5.7
