Did you look at that thread and not find instructions for flashing it? I'll take a look when I get home and find them for you, there are several threads with the instructions.

Sorry Im late. I have been having trouble with my desktop pc. Okay so go to the top of this page and look for the big red letters link to the ClockworkMod (CWM) Recovery easy install package , its best if you read the entire thread first.

If your tablet is not rooted install the arctool apk, there is a link there after the second paragraph.

Then watch the video on how to install cwm on your tablet.

once you are rooted and cwm is installed I followed the steps below to flash the roms. I compiled these from the other forum threads. If you have any questions do not proceed until you get clarification. You can reach out to Admin or Globula Neagra or others whose names appear on the threads! Look for the advanced members names for direction. Good luck!

Is there a set of instructions to do this ?

Instructions for what ? Updating ?

1. Shutdown tablet

2. Remove external SD card (if present)

3. Plugin USB cable into tablet
4. Plugin USB cable into PC, power on tablet

5. Install driver from rockchip package

6. Shutdown tablet

7. Start Rockbatchtool

8. Press Power & Volume+ to start tablet --> will be recognized by Rockbatch tool (green button at connected devices)

9. Load update image and click Restore ... wait until reboot

Installing driver is easy. Once you plugin the tablet on your PC the very first time the Windows OS will install a driver for the new USB device (look at the notification bar in the lower right corner of Windows). At this point in time just open the Windows Device Manager, select the new device, right click and choose update driver/install driver. Select "Browser my Computer ..." and choose the driver from the Rockbatch folder - especially the driver that matches your Windows version (Windows 7 / 64 bit etc.)

My way is typically:

1. Windows / Open Control Panel

2. Select "System"

3. Open "Device Manager"

4. Plugin the tablet

5. Start the tablet

6. Wait until the new device appears in the device list of the Device Manager

7. Right click onto the new device and "Install/Update Driver"

8. Choose the driver from "My Computer"

9. Done

I didn't used the power button to enter flash mode.

Shut down the tablet,

do not plug any cable into the tablet,

press the volume button, and while it is pressed, plug in the USB cable.

You must hear the beep from the PC, and the driver starts installing. Here you can release the power button.

If the driver didn't installed, don't worry, you can install it manually. The tablet has entered flash mode, it does not matter if the Windows driver is OK, or not.

After you have the driver installed, you can flash.

I have difficulty to enter flash mode (flash tool can't detect U30GT2 connected though windows driver had been installed successfully).

Below is the right way to enter flash mode found in user manual. (instead of holding volume + and power buttons at the same time).

1. power off U30GT2

2. hold volume +

3. connect USB between U30GT2 and PC

4. hold power button until PC detects new device.

5. release both volume + and power buttons.

Install MobileUncle Tools, or any number of "Reboot" apps that will allow you to reboot to bootloader, or to recovery, etc.
