We just bought an Asus Memopad HD7, and it has 4.2.1. It DOES NOT have the multi-user function like other 4.2 devices I've seen. I have posted a thread about this in the Memopad section but it's a very small forum, and I need to be able to find a way to get multi-user function on this thing QUICKLY or I am returning it. Had I known that it can't do multi-user, I would not have bought it. Other 4.2 devices seem to have the multi-user, which is why I bought it....so my children can play kid's educational games (preschool) without my fear of them getting into whacko stuff (either on the internet, Play store, or swapping the settings by accident). If I root this device (using Motochopper, seems to be the best way), can I safely flash a ROM that would have this multi-user? There are some multi-user apps on the Play store but they all require root, which I'm mildly wanting to avoid because of warranty issues.
