The mighty fenice57 from our forum has cooked a very nice custom firmware for the Arnova 7 G2.
This firmare brings root access to the device, Android Market, together with great additions such as CIFS (SMB/Windows shared drives), NTFS, ext4 , OpenVPN, Bluetooth on supported USB dongles, GPS support thru Bluetooth.
This is by far the best custom firmware we’ve try on the Arnova 7G2, that provides, according to our initial tests a quite stable Android Market and general system. We’ll publish updates in this article and a firmware flashing tutorial as we make progress with these tests. Feel free to come and discuss about this firmware on our forum.

Here is the latest ROM update
Flash only the boot.img and system.img
The personal data will not be lost but for safety Always have a backup.
Editing init.rc to improve the recognition and Bluetooth to use external Bluetooth GPS
Insert other commands in /system/xbin/ for bluetooth debugging and management.
Modified build.prop with several improvements for the system
Added GPS Bluetooth provider in /system/app
Now its possible to use usb bluetooth with active USB debugging and mock locations.
I remember that for the correct recognition of an external Bluetooth dongle, the tablet goes on with the key inserted.
If you physically disconnect the key and if then reconnect, the tablet must be restarted.

Complete support with USB OTG for Hauwei 3G key models E1550 E1692 E1750 E1820
I made the necessary changes in order to see external drives formatted with NTFS file system.
Mount NTFS disk – what to do:
Automatically at boot time the system will create a folder called win inside the mount point /mnt
Run GScript and add a new script, call it – mount-ntfs –
Enter the following command: /system/bin/ntfs-3g /dev/block/sda1 /mnt/win
Connect via usb otg the disk, start the script and entire contents of the disk will appear in /mnt/win
I did a test with a 1TB drive with my mkv and I was able to see to 1080p without any problems.
To umount the disk, create a new script, call it umount-ntfs and enter the following command:
During umount, all applications that are taking up the mount point /mnt/win SHOULD BE CLOSED.
If you do not, the script does not umount the disk and if the disconnected abruptly, you may lose data.
Entered all necessary kernel modules to support external USB Bluetooth to connect to the USB OTG cable.
Obviously the Android drivers are a bit limited, look on the various forums to see what sticks are compatible.
Of course, Bluetooth file transfer has been included to turn off and turn on and manage the Bluetooth
Added kernel modules in order to see share external network via the CIFS protocol
Full support for OpenVPN
Added kernel module tun.ko to use encrypted connections with OpenVPN server.
Inside /system/xbin directory has been added to the latest version of busybox
The openvpn binary was always placed within this directory.
All kernel modules are loaded at boot time
When the Bluetooth is on and the display goes to time out, the internal POWER signal is sent to tablet
Sorry NO update, you must flash all again
