I would love to know how to do this too.

Tried several times to get my U30GT mini into flash mode.

But it will not work, it iether starts up normally or it stays off.

As for ADB i think these are drivers for USB?

I recongnize it form flashing my HTC Desire it needed ADB drivers because windows did not see my phone.

So if you mean the ABD drivers how will this work if the Tablet will not go into flash mode from the start?

Thnx for the answer

You need first to enable usb debugging, find the drivers
then install android sdk which has included the adb

then use adb with the command adb reboot bootloader

use google to find more info about adb and how to use it

finally i did it work

you must turn the tablet off

connect the cable to the usb port alone without the tablet

then press + then the power button together when

when you pressing the two buttons connect the micro usb to the tablet

you will hear the sound of new hardware connecting

Release the two butons now..

Yes it seems the Cube drivers do not work well under windows 8

My Tab does go into recovery but it won't show up in the rockchip batch tool.

A quick look at the device manager shows the U30GT driver and the message it does not work properly. Seems for windows 8 you need to disable driver signature

I flashed and successfully updated my CUBE mini to from factory 1.0.3 a rooted 1.0.3 firmware.

I took this route mainly to be sure it would work and it did, although at the end windows XP said the rock batch tool stopped working. The tablet started up correctly and worked.

So I decided to upgrade to the 1.0.5 fw, and there it went wrong, halfway true the update process it all stopped. And now i face the widely now dead android, I can access to recovery menu but that is about all.

Flashing from sd will not work it tells me either that:

Apply update from external storage

E: unknown volume for path []

E: error opening : no such file or directory

E: unknown volume for path []

install from sdcard completeor

update from rk image

Find and check firmware

E: unknown volume for path [/update. img

E: can't mount /update image

Can not found firmware image or invalid image

update rkimage complete.

I have tried all the fw images from 1.0.3 original to the rooted 1.0.5.

None of those are recognized. I have read on this site (cannot find the topic atm) that someone succeeded in flashing from sd. If this will not work is my only option to open up the tablet? Since the current state it is in Win XP wil not see the tablet, so te adb road is not working either.

Any ideas?
