如需在 Glass 上获取 root shell 访问权限，请使用已启用 root 权限的引导加载程序运行以下命令：
$ adb reboot bootloader # enter fastboot mode, takes 10-15 seconds
$ fastboot devices # verify device is in fastboot, should see its serial #
$ fastboot oem unlock # unlocking erases all data, you are prompted to run this command twice to be sure
$ fastboot flash boot boot.img # gain root shell access with the rooted bootloader
$ fastboot reboot # reboot the device
$ adb root # start adb as root
$ adb shell # access the shell as root
如需将 Glass 刷回出厂规格，请提取所需的出厂系统映像软件包，然后运行以下命令：
$ adb reboot bootloader # enter fastboot mode
$ fastboot devices # verify device is in fastboot, should see its serial no.
$ fastboot flash boot boot.img # flash partitions with factory images
$ fastboot flash system system.img
$ fastboot flash recovery recovery.img
$ fastboot erase cache # optional, erase the cache and userdata partitition
$ fastboot erase userdata
$ fastboot oem lock # optional, only if you want to re-lock the bootloader.
内核源代码
您可以浏览内核源代码，也可以通过运行以下命令检出并构建内核源代码。
