h2. Installing ADB

Instructions to [[ToolsInstallation#ADB|install ADB]].

h2. Authorizing the device

In order to allow your host computer to access ADB on the device, it must be allowed on the device. A window should pop up when connecting USB, asking whether to allow USB debugging. 
*Note: when booting with USB plugged in, the window doesn't pop up and you have to disconnect and reconnect the USB cable to see it happen.*

h2. Accessing root shell

Once allowed, you can access the device shell using:

<pre>
adb shell
</pre>

The shell is running as an unprivileged user. To gain root access, use:

<pre>
adb root
</pre>

The following shells will then be run as root.

h2. Modifying the system partition

Replicant is installed on the system partition. By default, this partition is mounted as read-only and can't be modified.
You can mount the partition as writable filesystem using:

<pre>
adb remount
</pre>

Files under @/system/@ can now be edited.
