Default A fake "Samsung" 6110 Tablet from philippines

I got this from my brother during his trip to the Philippines for christmas and it came pre rooted. Is there any way to like install CWM on this so I can make a NANDROID just in case mistakes happen? And is there a way to speed up this slow tablet? I think is single core.
