Default [Q] Determine Model Number of Cracked Screen Tablet

Hello everyone,

I've been trying to replace a tablet screen on a Maylong M-270. I originally thought that there was just one model. However, I figured out the hard way that this tablet has many different model numbers in the M-270 class. Since this isn't a popular brand it's hard to find information on it. So now I have to figure out what the exact model is without being able to use the tablet. I took it apart and there is no model location. Truth be told this is my brothers tablet and since I'm the geek in the family with some gadgets it's on me to fix it. I was thinking about downloading SDK and see if I can detect the full model via windows 7. Is there a way to detect model and serial of tablets without the screen having functionality?
