    Have a nice day! 
    This ROM contains the Hungarian (MAGYAR) language?
    Or can you recommend a ROM that contains the JY-G4 Hungarian?

    Thank you!

    Hi, I  tried this/your ROM and it was very good.

    But as I'm from Europe(Czech Republic), I have to ask, let stock keyboard in this ROM please.
    I prefer stock icon too, but I understand that you are doing ROM aimed to your image.
