Hi swedski,
as long as you have the Allwinner A10 CPU here's what you do.
1. Download and install the Superuser app from Google Play.
2. Open the Superuser app and click on the "i" button, which is positioned on the upper right corner of the screen.
3. On the screen that shall follow, under "SU BINARY" click on "tap to get updates".
4. A new screen will prompt you to download the updates (requires an internet connection). Do that till it's successfull. If it fails a couple of times in the beginning don't give up. It will eventually work.
Then you are officially rooted.
