well i have the RCA Viking Pro 10" tablet and at no point and time does a robot show up on my screen i can hold the power and volume up button down for 5 mins and all it does is go back and forth from the RCA dogs and the words Viking Pro if i let go of either button it just loads the locked screen as before asking for a password i cant remember. For me all this was and did for my tablet is restart it it did NOT reset anything. And yes it uses the Android 5.0 Lollipop operating system. If anybody is curious as to why the factory reset function was disabled on this device the model number is RCT6303W87 DFK, good luck and happy hunting i'm going to get my 10oz titanium framing hammer and fix this piece of junk.
