Badnews，after the unbricking, i successfully registered，turn on wi-fi，and began to copy pdf and mobi files into k4.
then the windows explorer stunk! i waited for a while, and still no response. i have to close explorer in the task manager， and kindle turn white and bricked again. to be worse, there's no response of the power button. is there any possibility to wake it up?
