Yes it is true -partially

.
We can have all those language Emgeton offers in his firmware but have original resource from Meizu. Trick is simply as change a skin. Just take file: M6.EBN from Emgeton web page and file: resource.bin form Meizu web page. It works!
Even better because Emgeton translation is very poor (Polish).
The good news is You can use all skins you can find for your firmware version and keep all your languages.
I try it with FW 2.003.2
Thank You for cooperation
