Hello,

thanks very much for your phantastic work.

I own a Chuwi v99x and would like to root it. This is the only method I could find.

Unfortunately I am not able to follow instructions as my tablet has no volume up or down buttons and I cannot enter flash-modus.

Is there another way to connect the tablet to the PC in flash mode.

I would very much appreciate your help.

If there is a way I could help I would be please but I am a beginner and need clear instructions. I do not understand about logs or tablet version (1401 ???) unless you tell me exactly how to find out.

Flash driver will not work for win8.1. Also no usb3.0 ports are supported.

Google translate of the chinese stuff:

"After boot after V99X in connection with a data cable while the computer is connected to a home computer in the open V99X upgrade tool ... and then click the switch ... After the prompt discovery of new hardware to install the driver from the list, or at the specified location"

So, best is you use the included driver installer to make the flash driver work. Then use the "switch" button in the RKAndroidTool to start the flash-modus.

Maybe also holding power-off until tab is off and then plug usb-cable in while still holding the power-on will work.

Serial number (S/N) should be on the back of the tab. Here is a link to the factory images: http://bbs.chuwi.com/forum.php?mod=viewthread&tid=62&extra=page%3D1

OK, thanks. This might be the issue, I am working on W 8.1. Will try to find a machine with W7.

After that I report back.

--- EDIT ---

I attached a picture of my tab. What S/N do I have? I cannot find 1311/12 or 1401. Sorry for being inept in this task.

I would say your S/N is 1403. So kernel 1401 (which means 1401 and later).

To be sure can you pls post a screenshot of settings/About the tab?

Of course, here you go.

I must say that my frustration level is at the top now after trying last week to connect the tablet in flash mode. Nothing worked, I am sure I tried everything but not the correct method.

I used a windows 7 laptop, installed drivers in the package and launched with administrator rights the RKA. I even got a popup confirming the ADB drivers were installed and the device was connected in ADB mode. 

But the RKAAndroidTool.exe still shows permanently "No found RKAAndroid rock usb".

Sorry for crying but I really need help, step by step in the correct timing. Alone I am not able to connect.

After succeeding I promise to help and attach the logs.

Thanks

Ok, kernel bob #688 is the one for tabs with S/N 1400 and up.

Use the driver installer which is included in the package. De-install the driver first, then install again.

I am afraid I will have to give up.

Driver deinstalled and installed again. Tried 3 different usb cables, including the one supplied by Chuwi. Tried long button push, tried short, tried with tablet off, with tablet on and even during the switch on.

Nothing worked, sorry.

Windows 7 x64.

If anybody did the connection I would very much like to know how.
