Hello guys,

I've bought this J22 CYXTECH alias CYX_809III_RK3188T with stock ROM Android 4.4.2, I guess it's a clon from CX919II, I purchased it on **** but i saw it in many websites like aliexpress or alibaba (it's sold as CX919II ).

Well, at this point everything is working fine by now, but I need to have ROOT access. Any way to Root it ¿?

I put below the entire specifications I could found on the NET and some pictures in order to know if anybody here can help me to root this device

Hmm, I have almost exactly the same one, I have the CYX_809III_v5_2_20141105

Right now though, I'll settle for a ROM that works, never mind ROOT...

Ok, if you found any better ROM, please send me a message here or PM. Thanks.

Hi anyone!

I have the same CX919II as the user above, except I have a SANDISK 8GB memory chip instead of the SKhynix 8GB memory chip.

The motherboard is the same: CYX_809III V5_1 20140726

I NEED HELP!!

After I tried to root mine, and did all the steps accordingly with TPSparkyRoot.bat
It said the device was rooted. But after I started it, the app Root Checker said it wasn't rooted properly.
Also SuperSU said: "There is no SU binary installed, and SuperSU cannot install it. This is a problem! If you just upgraded to Android 4.3, you need to manually re-root. Consult the relevant forums for your device!"

After this I found a forum saying some folks with the same chipsets (v5.1) were only able to root the device properly using Kingo-Root.
So I installed this software, and plugged the OTG usb back into the device and laptop, and pressed 'connect to PC' (and USB debugging was on), but now my laptop didn't popup with recognizing the device anymore.
So I thought, Kingo-Root overwrote the Google USB driver with the one installed from PDAnet+, and therefore is in conflict. I tried cleaning all USB drivers from the registry with USBOblivion, but no luck.
I can't "uninstall" the Android ADB interface in device manager, because it simple doesn't show.

So I tried to factory reset my CX919II, but thenthe worst happend:
Factory reset worked fine, And I see the normal first time startup the way I bought it.
But WiFi and BT is not on, so I needed to plug in a normal wired mouse via it's USB port, so to go to the settings menu and set WiFi and BT on.
But the device won't show the mouse anymore!!
So I can't do anything on the device anymore!!!

What should I do?
I looked at hard resets, but only found to hold the only button on the device (the Fn button) while putting the power USB into the power socket. But all I get then is the blue LED light on, and nothing else. (black screen, tv says no HDMI devices connected)

So:
1.no mouse input available
2.hard resets don't work
3.can't connect device to PC

Please help!?
What can I do to at least enter the device again with a mouse or keyboard....??

Cheers....
