To make your rootfs writable, run the following command from a shell on the device: ( dut ) $ sudo / usr / share / vboot / bin / make_dev_ssd.

Auto updates may also fail until a full payload is downloaded. NOTE: If you mount the root filesystem in writeable mode, even if you make no changes, it will no longer be verifiable and you'll have to use a recovery image to restore your system when you switch back to normal mode. In developer mode you can disable the rootfs verification, enabling it to be modified. The Chromium OS rootfs is mounted read-only. NOTE: You can create as many shells as you want with again and another shell will be opened. If you want to get back to the browser without killing the shell, you can use. You might want to follow the VT-2 steps once just to get the instructions.

NOTE: Entering the shell this way doesn't give you all the instructions that VT-2 does (like how to set your password). NOTE: even if you set a password for the chronos user, you won't need it here (though you still need it for sudo access)
The instructions on the screen will tell you how you can set a password. This includes the ability to do password-less sudo. By default, you can login as the chronos user with no password. Once you have the login prompt, you should see a set of instructions telling you about command-line access. If your keyboard does not have this key, instead use the key in the F2 position which may be the refresh key or another key. Where the key is the right-arrow key just above the number 3 on your keyboard. If you're a Linux user, this is probably familiar. One way to get the login prompt is through something called VT-2, or “virtual terminal 2”. NOTE: Before following these instructions, remember to put your device into Developer Mode. The command prompt is built in to your device! If you‘re a Linux hacker, you probably know that Google Chrome OS is built on top of Linux and you’re wondering how you can jailbreak your device so you can get to a command prompt. However, as long as you don’t crack open the case, you shouldn‘t be able to do anything that can’t be undone by recovery (software). NOTE: If you‘ve made changes to the rootfs filesystem while in developer mode, you may have to use the recovery process to restore your device to its factory condition.

Devices without keyboard (tablet): Use the Volume-Up and Volume-Down keys to select the Enable OS Verification option.Device with keyboard: Press the Spacebar at the firmware screen.To restore your device to Normal Mode (i.e., disable Developer Mode), reboot your device and perform the following action: You can tell that you're in Developer Mode if you see one of these screens when you turn the device on: Please follow the link to read more details about blocked Developer Mode. If you’re encountering issues putting your device into Developer Mode, it's possible that your device administrator has blocked Developer Mode access on your device. It also gives you access to a “root” shell. Specifically, it makes the “verified boot” that's built-in to your hardware a little bit more lax, allowing your hardware to run custom (non-Google-signed) images. NOTE: Putting your device into developer mode inherently makes it a little less secure.
