Such firmware flashing should only be done for recovering dead players, and not for plain firmware updates. So if you player does not function properly (it blue screen), then you should flash with these firmwares.

The problem with these players firmwares are that the version numbers are not accurate, and even the same version number would most likely not work for your player. So it's all a matter a trial and error. You'll need to keep trying all the firmwares until you get a working one.
Good luck.
