I have a chinese, android tablet, from amazon, .... I cant get in with my password. Is there anyway to get by this, or change, do I even have an option. Ive hooked it up with USB, but computer spots it, but cant get further. I took the back off, and found no numbers, and battery is soldiered in. I can get it to the green android laying on his back with a red triangle, but dont know what to do after! Help plz
