ever since flashing the latest rom, charging for me has been really slow, i went from 31 percent to 60 in 4 hours, when the screen is off, the orange indicator light is on, but when the screen is on the indicator light is off, and under status in settings it doesnt say it's charging but the circle indicator in the right hand corner shows that its charging. could this be the result of a bad flash? only had the kindle for about a week, hate to tihnk i've damaged the charger plug
