'New 2018 edition' ??

[leonkoum]

I am seen two different edition of this player which take different firmwares..
One is the 'rev 292a' and the other is 'rev 292b'..
That is the difference between this two boards? 
Tnx

I asked dune and replied
there is no spesific difference ..

 maybe board has minor changes and every fw needs a little different codes..
