Hi, wasnt sure where exactly to post this question. My son owns a PENDO pad model: TPC7SLV - he had downloaded a "lock" called "GO LOCKER" onto it, he then attempted to put another version of this GO LOCKER on, then tried to go back and un-install the first GO LOCKER application, which half worked & mucked up the new version of the GO LOCKER application, so he attempted to un-install the whole lot of the application, however I don't know what else he has removed because now when you turn the Pendo Pad on, you use the slide-lock to open the page it opens onto a black screen- when you click on the HOME part it doesn't do anything, no other buttons bring up any options either? at the top bar it shows the time, volume, 'go back' button which only the volume button does anything. the sd card isn't in it at the moment, which I don't think should matter? Please help - not sure how I can re-set it to factory settings (whether or not that will help) - I'm not to technologically minded, so if anyone has ideas what I can do with this - thank you.
