Please help! My brother entered a wrong pattern a number of times hence the tablet prompted for 1. "Too many pattern attempts" hence I need to sign in with my google account but 2. "Invalid username or password" although I can sign in with my gmail account in my laptop So I tried to connect my USB cable to laptop supposedly to retrieve password through USB mass storage but 3. "Device not recognized" Then I tried opening Device Manager --- USB --- USB Root Hub --- Power Management but still nothing happens. Please help me solve this ASAP!!! By the way, its a Samsung Tab 2 (Clone) which I bought at JK Store in IT City, Bangkok, Thailand last October 20 and later I found out to be a Topwise Android Tablet.
