Yeah, win8.1 and the unsigned Rockchip driver are not friends.

Here is a driver assistant, which may work: http://crewrktablets.arctablet.com/?wpfb_dl=2398

Do not use usb3.0 ports.

Alas, tried everything to make the above work but got nowhere.

I'll try to find a PC with Windows 7 to get this done.

I found a Windows 7 machine and I got my tablet to run 4.4.2 in just under 10 minutes

It is working really well now, I am so happy. ^_^

This forum is a little old, but since these tablets are on good sales since they are being discontinued I thought I relay my experience to help people not get into the trouble I did. If you recently bought your tablet this rom and most other custom ones online will not work. I know, because when the one provided here didn't work and since I neglected to make a backup like the idiot I am, I tried everything I could find. Luckily after 6 hours I found a solution. Just in case it helps anyone I provided it below:

1. I often had trouble getting it into flash mode, but I kept trying and it would get back into eventually. Try either pushing both the back and power buttons for several seconds or the reset mini button. Then reconnect by holding back and inserting the usb.

2. On my box I have a sticker that states "CVNZ-9470-White-2GEN". Noticing the 2GEN was the clue that solved the problem for me. If you still have the box see if it says 2GEN. If so proceed to step 3.

3. If you go to https://download.chinavasion.com/Others and scroll all the way to the bottom you will find:

- CVNZ-9470-Black-2GEN_444.part1.exe
- CVNZ-9470-Black-2GEN_444.part2.rar
- CVNZ-9470-Black-2GEN_444.part3.rar

Download all three. Note that there are only entries for "Black", but these worked on my white tablet. It doesn't matter if you're black or white so to speak.

4. Once all are downloaded click on the .exe file which will give you the image and RKBatchTool. Use the batch tool to flash.

A few extra notes. The bootloader is 2.19 and it is Android 4.4.4.

Good luck.

Thank you for sharing!

We know three hardware revisions: CT9716 (JB & KK), CVNZ 9470 (JB) and CVNZ 9470 2nd gen (KK).

I have the same white tablet. I upgrade the android from 4.2.2 to 4.4.2 without problem. Unfortunately the above version 4.4.4 does not work. I don't know if the reason is the tablet or the installation.

The installation is normally but the tablet refuses to start. Always shows E-CEROS and only this.

My guess is that your tablet is not a gen2 tablet. My gen2 originally came with 4.4.4, but I was looking for some rom that had more than 2 gigs for app storage. I tried prior versions to 4.4.4 with larger app storage partitions, which got me into trouble.

I would be surprised if they shipped gen2's with 4.2.2.

Try connecting in download mode, remember having those problems. Could be update from ADB or something. Then just Connect to batchtool. Good luck
