I know there are lot's of questions about this, but I haven't seen any that specifically match my question. I am trying to lock down a galaxy player 5.0 for a friend, so that it is virtually impossible to install other apps-unless you know what you are doing. I rooted it, downloaded Mobogenie onto my computer to back up the apps in case I want them back again, and started uninstalling apps with a 3rd party app, DuBoost or something like that. Now I am wondering, if I uninstall the package installer(having backed it up first) will it be possible to reinstall it with Mobogenie if I later want to install some more apps? I don't really want to render it useless permanately, so I didn't know if anyone else tried the same thing?
