i Just purchased my tablet today and it updated it with an 173... mb file. I'm guessing its the update to support ps3 controller, Ever since that my tablet screen has been stuck on some android picture with a caution mark asking it to connect to the charger. I did it even after 3 hours its still been stuck on the screen. Please help is there any way i can switch it off or should i just let the battery go dead or what am i supposed to do??
