A few days ago, I found a need for the opposite of this, Infrequently Asked Questions! I had a problem with my daughter's HTC Incredible 2, so posted on the forum there. I was quickly told by a super-mod that this sort of error doesn't usually happen, so (after trying a tweak he didn't expect to work) try a factory reset. When that created even stranger results (the Factory Reset process force-closed!) he said try again and if that doesn't work, do an RUU (like SBF) or, more likely, return to Verizon.
This sort of stuff is really very useful, as it tells you there is no need to look for subtle solutions, try reset, rewrite, return... I guess once the FAQ contains all the info, then we can say do this if it isn't in the FAQ!
