  1. Nice to see they are still improving the firmware!Excellent job and thanks for sharing.

    Let’s hope Android 4.4 will arrive soon 🙂

  2. Has anyone tried this on the Tronsmart CX919 yet? I’m currently using Finless 1.6 and I’m not sure if it’s worth flashing. Hopefully the improvements will be included in the new Finless ROM.

  3. Just tried this new Rom. Finless 1.6 is better. This rom won’t let you install apps like MLB, and thousands more. Finless spoofs a specific device so Google Play will let you install these apps. This rom is clocked at 1.81ghz according to CPU-Z

  4. Thought so. No reason to change when Finless is running well enough. Thanks.

  5. I can not get it to flash.
    I use Rkbatchtool v1.7 and driver version 3.07.

    My cx-919 not determined windows 7 and 8, as defined in the windows.

    Rkbatchtool within my cx-919 with the parameter SUPPORTLOWUSB = TRUE.

    log firmware upgrade is:

  6. If this is the offciial update, why is it not sreamed through internet.

    I thought this was the whole idea with this sticks.

    My CX919 is from June has Android 4.2.2 and works wel.

    Only hardware acceleration stops within 2 minutes, but soft acceleration works fine. cannot see any difference..

    Keep up thye good work,

    Bye bye,

  7. Does this newest rom include 1080p support as did the previous one?
