    It seems to be stable and it is rooted.

    The others versions could be rooted too.

    If we update to 5.1 and it doesn’t work as we like can we update back to 4.4 – will it come from internal storage or would flash card or a usb stick be needed ? Thanks

    Of course, you could back to 4.4. I did it several times.

    Put your archive on your USB stick or your memory card.

    1. Download the firmware.
    2. Extract all the files in the zip to a freshly formatted SD Card.
    3. Make sure the power IS NOT connected and Insert the SD Card in the TV Box
    4. In the back of the device, Locate the headphone connector and insert a tooth pick or something none conductive into the hole. You should feel a button being pressed.
    5. Press and hold the Button in the headphone hole while plugging in the power. Keep holding the button for 10 seconds
    6. If you did the steps correctly you should see an green Android robot with a progress bar below. Your box is now updating. DO NOT TURN OFF THE POWER OR TOUCH THE BOX!
    7. When the update is completed your box will automatically reboot on it’s own. The first boot will take some time so be patience

    Attention: SU (super user) is integrated in this update. If you start SU it will ask to upgrade, DENY IT otherwise after reboot android will continuously restart. For the rest, this update works very stable.

    Yes the WIFI works on the new Firmware 5.1.1, to turn on must input your WIFI password ,, it works try it,,, The new update works the best on KODI , I am running all the apps from Kodi … runs strong and very fast…

    I tried this ROM a few days ago, but have since returned to 4.4.
    Theres still no bar with home, task manager etc. Perhaps that can be added with an app. I also had a few problems with my internet connection dropping out on ethernet and Google play force closing.
    I’ll call back every now and then and try out any further releases.

  19. 1 dman said:


    I’ve one of these boxes but there is no status bar with notifications.

    Is this a bug or a design decision, has anyone got this rom installed, does it have a status bar with notifications?
