Hello this is a warning to people on 3.80 M33. I just installed 3.80 M33 and decided to try and download the revision 2 update from network update. I did and it completely screwed up my memory stick. I had a lot of hombrew in the game folder and game380, but after downloading the update all it showed in the xmb was one corrupted data. I have already tried running chkdsk, which didn't do anything except completely get rid of my game folder (where all my 1.5 kernel hombrew was). So if you are on 3.80 M33 just download the revision 2 update from the computer!
