Hello all,

First, i precise that i'm french, beginner and i'm sorry for my very bad english.. :/ Please write simple sentence for me ..

I try to flash my tablet arnova 10g2 for install android 4 with this tutorial:

http://www.arctablet.com/blog/featured/flashing-arnova-g2-rockchip-2918-rockchip-flashing-tool/

But i have a problem, when i press vol+ and reset button windows 7 say the usb not recognize. I think that i have a problems with drivers..

I have somes question about it : 

The tablet must be turned on or off before the moment  of vol+ and reset??

When the usb cable must be connected to the pc exactly??

I have seen in other forum this :

On W7 I go to Control Panel / System.
Then choose 'Advanced system settings', on the 'System Properties' screen go to the 'Hardware' tab and click 'Device Installation Settings'

In here I chose 'No, let me choose what to do' and then 'Never install driver software from Windows update.

I have try all this solutions but all of these not work for my tablet..

I'm sorry if i misunderstood the arctablet tutorial and i thank you in advance.
