I dont recall Matrix having v1.51. Are you sure you dont have a clone cause if you do you can kill the chip by trying to upgrade it. Does it still play backups after you tried to upgrade it?
They did have a v1.5 and v1.54 but never v1.51 that I can see on there web site.
Just cause the screen says Matrix doesnt mean you have a real Matrix.
