Yes, you'll need to download a SDK pack as wells as USB drivers so that you're PC can recognize the tablet. I use adb with my archos to push new ROMs. Once you download the SDK pack and the correct USB drivers, you should be able to push/manipulate files in the OndaVi40 if that's what your after.Thanks smithmail.
I'm reeding the 3d.
Atm I can enter in recovery using terminal emulator and script or using the reboot system of cm9 rom ( press power button -> reboot -> recovery ).
In an other post I've read that can be reboot in recovery using adb.
But ... I've to install any drivers to do this?
A link discussing adb install and interaction am Archos G9 tablet can be found in the link below. You should be able to find OndaVi40 drivers from TNT's page on Onda ROM flashing linked on post # 158
