Hello guys.
Yesterday i just got an used tablet from my parents and do you know what? it was rooted including SUPERUSER!
I did NOT root this tablet. I just unboxing the tablet, configure, install some apps and i just saw Superuser on app drawer. This tablet Denver TAQ-80053 is good and fast, have quad-core processor, 1,2 GHz. Fine... and Superuser also works as it should.
Now i can hack game using Gamekiller :)
