Hi,
I juste tried to update to last version of 1.04. It failed, and I have a android monster with a red exclamation mark out of his belly.
What are my option ? Windows does see U30GT tablet, with a question mark. I cannot load the good driver. Please tell me how to reformat this and load a new ROM. I saw some hardware tutorial to reset the ROM.
Tell me what is the best way to recover from this issue.
Thanks.

Can you enter recovery menu? power+ vol up?
there are recovery options like
apply update from sd external storage or
update rkimage from sdcard

The only proper way to fix a bricked device, provided it powers up and get detected is to flash a firmware using Rockchip Batch tool.

Guys, i don't know it's called bricked or not.
But yesterday i flashed my Cube U30gt-H and it said "Loader Failed" or something And my tablet suddenly rebooted but it went to picture with android and red exclamatory sign pop up from his stomach.
And now, everytime i try to push power button, it always goes to that red exclamatory again. And i don't have any ideas.
Can anyone help me to sole this problem? 
Thanks before

Downloaded rom inside got image file.

Any advice regarding downloaded image file to RK image file?

Recovery from sd card won't work. The only way to unbrick your tablet is ti dissassembled it as describe into matheos post.
Once open, you have to short the pins 29-30, then boot your tablet. Once the device will be recognize into windows, (drivers will be installed), stop shorting the 2 pins. Device will now be recognize in RBtools and will be in blue. You can now do a RESTORE with your firmware file. DO NOT DO AN UPGRADE.
My friend did it this way and was able to unbrick his U30GT Mini. He also had to use an older firmware.

bricked on the first day resurrected on the second, and all I can say is that my problems ended once I replaced my hard drive, install vista enterprise 32bit + drivers for U30GT-H and BANG RK30 Tools is working fine and flashed the tablet with kasty-cube_u30gt_h image, all is well now, very happy with the dam thing actually.

I got the same problem. SD card won't boot. PC recognized it but asked for U30GT-M drive which is not available from any of the recently updated firmwares of RK tool kit v.1.5. Where can I get the cube U30GT-M driver?
