There is three things there. the first guy claims the installing SU app is enough, but it failed immediately when I tried following his Youtube link.
The next guy leads me to two methods, but one is reserved for SONY phones, although one model of Denver tablets seems to work with it, but I have tried Xperia rooting which didn't work at all for me.
The third method, I get stuck at installing an inf file. My PC says the file isn't made to be installed by right clicking it, but I do not know another way. I'm gonna save it though until I can complete the process and hopefully root my almost useless tablet :)
