    Hi Farrucon,

    Just updated the method again with video, please check it. 

  • Hi
    trying to update Android 7.1 firmware and following the steps indicated
    in the video, it does not happen to me of the first screen (probox and
    white background).
    It's impossible for me to update. Use tf card of 8gb, and izarc program, to decompress.
    1. Can not be done via OTA?
    2. Is there another method to update my probox2 air plus?
  • The Update does not start for me. The Probox2 logo is shown indefinetely.
    Is this update working for probox2air? Is there an option to flash via usb?
  • Dear All,

    For the firmware upgraded to Android 7.1 and cannot downgrade by TF card, you have to use PC to flash the firmware again.

    1. You have to use USB (male to male) cable to connect the USB port (near TF card) of Air Plus with PC.
    2. Do NOT insert the Power adapter.

  • Thanks hkadmin for this. Plese is there anyway to do samething to upgrade from android 6 to android 7.1 using same method? It was impossible for me to upgrade with TF card!! so using usb tool maybe the solution. Thanks alot.
  • Hi there,

    I havent seen any updates for this box, if 7.1 still being supported?
