Kindle PaperWhite卸载多看系统

Kindle PaperWhite的多看系统突然无法进入了，看一下貌似这个系统没有继续开发支持了，于是就准备删除掉它，操作如下

1. 将Kindle连接电脑，进入DK_System/install文件夹
2. 删除UninstallLite.sh，重命名DuokanUninstall.sh为DuokanInstall.sh
3. 长按电源键30秒，重启之后就删除了

移除脚本如下

#!/bin/sh

# update 20131218

uninstall_all()
{
        #clean old DuoKan script
        rm -f /etc/rcS.d/S79switch

        rm -f /etc/rc5.d/S96rundk
        rm -f /etc/rc5.d/rundk.sh
        rm -f /etc/rc5.d/S95dkupdate

        #clean new DuoKan script
        rm -f /etc/init.d/DK_switch
        rm -f /etc/init.d/DK_run
        rm -f /etc/rc5.d/S95DK_switch
