Hi guys, i've just bought one of these tablets. I've downloaded and ran the JB 4.2 update from the Sumvision website and it seemed to be going ok until near the end when it said it had failed. Now the tablet wont go passed the intial 'splash screen' and i sometime get the droid on his back with the red exclamation mark. I've tried the reset button but no difference. Any help would be appreciated. Thanks.
