I have an art tablet, its the art trek, model 9020aa with Android version 5.0 and kernel version 3.4.0 and I would like to see if I can get it rooted, I've tried a couple root methods but all have failed.
I see. Hmm, towelroot is also recommended for this case.
But I didn't try it myself so can't say much on it.
Otherwise I would try to root device from computer,
not sure the correct name for the application, but
shouldn't be hard to google. It helped me to root
one of the Mediatek's tablets long time ago.
