Can't do almost anything after Factory Reset

I have a serious and annoying problem with my tablet. After factory resetting my tablet, I still get random app stops. The apps that keepvon stopping are: Youtube, Dropbox, Myscript Resource Manager, Samsung Account, Google Play Service, and most other Google applications. And I can't seem to see my keyboard but I fixed it by disabling Myscript resource manager. After connecting to my WiFi, I went into some apps that needs internet or basically went into Google Chrome but I was not connected to the internet it says. And one last problem, I can't seem to view any files on my storage files or my SD Card files but I crash when I insert an Sd Card. I need answers please tofix this problem. Thanks
