To gain root shell access on Glass, run the following commands using the rooted bootloader:

$ 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

To flash Glass back to factory specifications, extract the desired factory system image package and run the following commands:

$ 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.

Kernel source code

You can browse the kernel source code or check out and build the kernel source code by running the following commands.

  1. Download the source:

    $ mkdir <path-for-kernel-source>
    $ cd <path-for-kernel-source>
    $ git clone https://android.googlesource.com/kernel/omap.git
    
  2. Download a prebuilt gcc:

    $ git clone https://android.googlesource.com/platform/prebuilt
    $ export PATH=<path-for-kernel-source>/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin:$PATH
    
  3. Build the kernel:

    $ export ARCH=arm
    $ export SUBARCH=arm
    $ export CROSS_COMPILE=arm-eabi-
    $ cd <path-for-kernel-source>/omap
    $ git checkout glass-omap-xrr02
    $ make notle_defconfig
    $ make
