And, to amplify on what Longshot just said, DO NOT try to upgrade any firmware on your Gryphon with any Edge application! You don't have an Edge anymore, you have a Gryphon.
Now, what Longshot was talking about are firmware updates that PHP has generated. Yes, there have been two. Both are minor and deal with issues that you probably have not had.
However, if you really want to upgrade the firmware in your Gryphon, read this:

Make sure you have set your truck back to stock before you take the Gryphon out of it!
