Do not believe everything on the Internet! I learned this the hard way by following a seemingly knowledgeable forum. I modified the installation package that I was using to update my CyanogenMod phone to get past an error. It seemed that the error was rather important because after removing that warning I hard bricked my phone. Not a soft brick, a hard brick. The phone would not turn on. It would not even go into recovery. This was not a fun way to spend a weekend having to switch motherboards with an extra phone my father had that had a busted screen.
I did end this experience with the updated phone but please be careful on the internet!
