Ok, this is helpful, but I need more help. I've been trying for a week to figure out how to install apk's. Apparently my tablet is missing the file explorer also. When you say android/tools directory on your pc, I assume you mean tablet, right? So how do I connect it to my pc so I can see the files on the tablet? When I connect it I see 3 drives, G, H & I. H is the only one I can look at, all it has is a directory called DCIM with a subdirectory of 100ANDRO with no files in either. So how do I see this android/tools directory?
