I have a Coby Kyros 8125. I used a youtube tutorial to download the android market without rooting. It worked for a day and then all of the sudden it will not turn on or off. It goes to the "Coby" screen, flashes black and then goes back to the "Coby" screen. I have tried the hard reset button and the factory reset and all I get is the ! inside a triangle nest to an android figure. A friend suggested I download the image sd internal usb image tool to my sd card and try resetting/factory resetting it again but it still has not worked....please help!!! I am semi-tech savvy but detailed instructions would be helpful. Thanks!
