    I have the G2 dual core.
    Talking about ROM’s, I have a problem.
    When I’m trying to download some applications from the play store, like Whatsapp and Waze, I keep getting the message:

    “Your device is not compatible with this version.”

    My temp solution is to install the application’s APK, and it works.

    What can be the problem? What can be done?

    Thanks in advance.

    I can’t download the ROM. I downloaded tools and manual.

    is there any mirror?
