Yesterday i bricked my tablet after trying to install the latest beta firmware.

 

So if it can help somebody it's possible to recover from a pretty deep brick in the same way of the u30gt by putting the tab in Maskrom Mode.

 

I don't want to steal so the autor of this tuto is Kriss from flashmyandroid.

Method to recover Cube U30GT tablet if it doesn't go into flash mode or start.

Have a suitable ROM for your tablet type (W,H, or T model, look for model in the serial number)
First forced shutdown "Hold power button for 10 second" and restart a few times.
   Combined with the boot to recovery "volume up + power".
Dis-Assemble the tablet. If you don't have the necessary skills and tools ask a qualified friend to do it for you.

Video Tutorial thanks to Pandawill:

Identify  the 2 contacts on the circuit board show in the below picture:

Connect the USB cable to computer (use a tested high quality USB cable; recommend using a back-plate USB port) to enter Maskrom flash mode. You must make contact between the 2 contacts highlighted in the picture. Keeping the contact closed, press POWER SWITCH on tablet. If everything is okay the computer will detect a new device and install a driver for it, remove contact. The USB drivers from the firmware package will do fine.
Start up RK Batch tool and look for a DARK BLUE square (NOT Green or any other color as Blue signals that you are in Maskrom Mode ).
Load the firmware and press RESTORE not upgrade!
The tablet will restore the boot ROM, then it will low format and re-flash the ROM

If everything went well you will have a  fully restored functional tablet.

WARNING
Take care when messing with the tablet internals and not to make any short circuit with the battery or other components, touch as little as possible or better ask a friend with electronics qualification!
Also don't touch IC's from tablet, they are sensitive to electrostatic discharges (don't wear anything synthetic).
Don't puncture, bend or short circuit the battery, it may explode or provoke severe burning.

On the u30gt2 the two contacts are here : 

 

For me fhashing in Maskrom mode fail at idb but after that i was able to reflash the tablet in normal way.
