A new user has posted a few times about a website that offers a download they say can root many devices including the new Sprint Tab SM-T217S.
The website is out of China and it is a new site. The company behind it is Kingsoft Technology Ltd. Their website has a few translation issues but it is mostly readable.
The site claims their software has been used by millions of users on hundreds of thousands of devices.
Perhaps they do exactly what they say they do, I don't know.
What seems more likely is their software may install something insidious on the Windows machine and the android device you are rooting.
I may test the software on a fresh Windows machine but I am no expert.
Does anyone have experience with KingApp? If I am way off base here please post that here.
