Despues de un par de horas lo logre, aparentemente el problema esta en el Driver Universal. La solucion la encontre en la siguiente pagina:

Hello,
i have rooted now my CX-919 with Firmware 0715.
Very Very strange thing and several hours of study the world wide web...
here found my working source (works great...very very thanks for this information!)
http://www.flashmyandroid.com/forum/...RK3188-tablets
test with windows 8 x64 ok
how to root firmware 0715:
1. plugin cx-919 with usb-cable on "usb" to usb-slot on computer and wait for detection as "cx-919".
2. a new device detected, called "cx-919", go to device manager and install the
latest usb google sdk driver from sdk android 4.2.2 file "android_winusb.inf"
path to file: RK3188_ROOT\usb_driver
(included in this file, modded for x64 and x86 os for rk3188 detection).
3. after installation usb-driver, cx-919 now detected as "android composite adb interface"
for test driver install go to root directory from attached file and go to cmd and call:
adb devices
you should see a message like this:
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
0123456789ABCDEF device
4. next call "TPSparkyRoot.bat"
5. follow the onscreen instruction, 3 reboots and you have root
(wait for every step at least 2 minutes, so you are sure your device is rebooted and ready for next step...)
6. plug in cx-919 in tv and start app "Super SU" execute binary update and upgrade to latest version through google play store...
Installing on Windows 8 need a fix, please read!:
Command Prompt (as admin!)
Disable driver signing :
bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit -set TESTSIGNING ON
Reboot
(on your desktop you see the watermark : 'Test mode' This is permanent, even after every reboot till :
Enable driver signing :
bcdedit -set loadoptions ENABLE_INTEGRITY_CHECKS
bcdedit -set TESTSIGNING OFF
Reboot
