    Download RKBatchtool V1.7 from our resources

    Follow these steps:
    1. Shut down your tablet.
    2. Remove any microSD cards.
    3. Make sure the tablet’s not plugged into your PC.
    4. Press and hold the volume+ button and power buttons on the tablet while plugging the tablet into a PC with a USB cable.
    5. Do not lift your fingers from those buttons until your computer detects new hardware.
    6. If prompted to install a driver, navigate to the Rockchip Batch Tool folder and look in the RockusbDriver folder for the appropriate driver for your PC.
    7. If you’re not prompted, you may need to go into the Device Manager, look for an unknown device, and install the driver manually by using the “have disk” option.
    8. Once the driver’s installed properly, you can run the RKBatchTool.exe program. You’ll know everything’s working properly if the box marked “1″ under “Connected Devices” is green.
    9. Click the … icon next to FW Path to find the appropriate .img file.
    10. Click the “upgrade” button.
    After that, the program should send data to your tablet and a few minutes later it will reboot into Android.

    flash mode is black screen you won't see something on your screen
    shutdown the tab, put the usb cable and you still see nothing happened on the pc/tab
    hold volume + and power button together and you will hear a beep sound on the pc that it found a new device.

    I dont know for what. I try and I try but nothing. And the first time I flash my cube all the procedure work perfect. OK merci maybe juste my timing with vol+ power and the cable. I will try again :) tanks for your time.

    EDIT :

    I finally found the way, and this could perhaps help other people who are stuck like me. Simple make in Settings / Developer options the USB Debugging is on. If, like me, releasing the Vol + Power and USB cable disconnect you the usb mode and you launch android, in RKbatchtool click on switch and sending you directly FlashUSB mode :)

    anyway, now, it's more simple (unless bad flash or brick) to boot normaly and clic the switch button in RKBatchtool.

    tanks all

    Just to share my experience, I had a bad flash (semi-brick) that made me a continuous LOOP, I was not even able to turn off the tablet. I restored the firmware v1.37 with RKAndroidTool with [reboot2flash]. And while you be with this tool, I flashed the different modules of 900SuperSport 4.2.2
