Cube U30GT Firmware Upgrade Instructions (v1.3, 11th June 2012, Tested on Cube U30GT-W V1.06 Firmware and Cube U30GT-H V1.01).Thanks to Krikkit for confirming that it works on the -H model.

Note: This does a WIPE upgrade so make sure you have anything backed up before you do this! After this the tablet will be as it was when you received it except on a later firmware.

1. Download the latest firmware (see this link)

2. Within the firmware there is a Rockchip batch tool but this is in Chinese so use this version instead

3. Extract the Rockchip batch tool which includes the necessary drivers for Windows

4. Run the RKBatchTool_1.5.exe in the extracted Flashtool folder and select the image you downloaded from Cube

5. Shut down your tablet

6. Plug the USB cable into your tablet

7. Now pressing the power and volume + buttons together connect the other end of the USB cable to your PC

8. Once Windows notices a new device release the 2 buttons

9. When asked for drivers browse to the "drivers" folder within the extracted batch tool folder and select it allowing windows to install the driver. If you aren't asked for drivers and you get a device install failure go to Device Manager and look for Unknown Device. Right click on this and select update drivers. Browse to the folder within the RKBatchTool folder with the drivers for your OS (Win 7 64 bit in my case) and select this folder.

10. If all ok the "device 1 connected" square within the RKBatchTool_1.5 will change from grey to green

11. Press the "upgrade" button in RKBatchTool_1.5

12. The green square should change to orange showing that the flash operation is happening

13. If all ok you should get a success message at the end (takes about 3 minutes)

14. The tablet should reboot but if it does not then press the power button

15. The first boot after an upgrade takes much longer than a normal boot. Just be patient and wait for the lockscreen.

16. The default language will be Chinese. When you get a prompt hit the home button and then go to settings and look for the menu option with a letter A in a white box (this is language). Select this and then the top option on the right hand side of the screen. This will give you a list of languages. Select English (UK) or whatever and then restart the tablet.

17. Don't forget to click green + bottom right of this post if this has helped you.

Change History:
v1.0 Initial untested version
V1.1 Updated following testing
v1.2 Updated to show that this is untested on the Cube U30GT-H model. Added change history.
v1.3 Updated to show that these instructions work on the Cube U30GT-H model (Thanks Krikkit)

NOTE: I take no responsibility for you updating your device. You do so at your own risk. Please use the tablet's own update feature if available as this is a lot safer.

Using Google Translator I did the best I could with the instructions. If any one would like to clean this up feel free.

Thanks
Thanks for your efforts.

I was holding off publishing anything until I get my tablet and can verify that the upgrade procedure works!

I have now added firmware upgrade instructions to the first post but these are untested as I have too much else on today.
USE THEM AT YOUR OWN RISK.

I will test them with v1.06 when I get a moment tomorrow.

Hey Jez are these tested now with your 1.06? If not, how have you been doing it?


Also do we have the english version mentioned in "2. Within the firmware there is a Rockchip batch tool but this is in Chinese so use this version instead (link to be provided)"?

Read my last post, will test tomorrow..too much on today.

I have the file I just need somewhere to host it so that everyone can download it. I have pm'd the admins to ask for a location.
If you need it in the meantime pm me (hint: you won't need it unless you have a tablet).

Hi Aris,

No problem, have sobered up now
I have updated the instructions with a link to the batch tool and updated a couple of other minor points. At some point I plan to add screenshots but this is on the back burner for now.

Thanks for the positive feedback. Glad the instructions worked ok for you too


Actually, compared to my sanei tablet the firmware upgrade seemed pretty straightforward.

I have a problem updating. The computer does not install the drivers, put the drivers have not been found and there is no way to be installed.

I have fix the problem in the device manager choosing manually de drivers.
That's what point 9 in my instructions says

Interesting, maybe you can tell us how it differs from the -W version when you get it.
It is supposed to be the Hong Kong version but can't see why they would make a special version. Any ideas?

Yes mine had Google Play out of the box.
