It should be said that getting a DSA error means the flashboard has a bad area, and yes the dev chip will disable the dsa check and let you boot up, but it doesn't mean there's nothing wrong with the board. Sometimes the damage to the flash is in an area that has consequences to game play, could be graphic issues or could be logic issues, which would cause the game to lock up if that area of the flash gets used. If you just acquired a flash board and you are getting that error, you should try and get one that is not giving you that error since you paid for a working board.
