Factory Reset doesn't do anything

[Froalskiner#WN]

I'm having an odd problem. When I delete an app on my tab, the app restores itself after I reboot. I figured something was off so I tried a factory reset. After the reboot it goes back to where it was prior to the reset. I change the wallpaper, it reverts on reboot. I even tried doing a hard reset with the power button and volume down. I was able to get into the stock recovery menu and do a wipe there as well. When I reboot, you guessed it, nothing happened.

Does anybody know what the hell is going on with this thing?

Did you buy your Tab used? It sounds like you have a display model. They are often locked like that to prevent shoppers from messing them up.

Nope, brand new and shrink wrapped.
