7 | 5 | Wolfgang Wiedmeyer | h2. Enabling ADB |
8 | |||
9 | In the settings, open *Developer options*. In the Debugging section, enable *Android debugging*. |
||
10 | |||
11 | 1 | Paul Kocialkowski | h2. Authorizing the device |
12 | |||
13 | 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. |
||
14 | 2 | Paul Kocialkowski | *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.* |

16 | h2. Accessing root shell |
||
17 | |||
18 | Once allowed, you can access the device shell using: |
||
19 | 4 | Wolfgang Wiedmeyer | |
20 | 1 | Paul Kocialkowski | <pre> |
21 | adb shell |
||
22 | </pre> |
||
23 | |||
24 | 5 | Wolfgang Wiedmeyer | The shell is running as an unprivileged user. |
25 | 1 | Paul Kocialkowski | |
26 | 6 | Denis 'GNUtoo' Carikli | To allow root access, open the *Developer options* in the settings. There, press *Root access*. In the pop-up menu, select either *ADB only* or *Apps and ADB*. A window with "Allow root access?" might pop up and explains the security tradeoffs of enabling root access. After reading the text, select OK to enable root access. |
27 | 5 | Wolfgang Wiedmeyer | |
28 | To finally gain root access, use: |
||
29 | |||
30 | 1 | Paul Kocialkowski | <pre> |
31 | adb root |
||
32 | </pre> |
||
33 | |||
34 | 4 | Wolfgang Wiedmeyer | The following shells will then be run as root. |
35 | |||
36 | 1 | Paul Kocialkowski | h2. Modifying the system partition |
37 | 4 | Wolfgang Wiedmeyer | |
38 | 5 | Wolfgang Wiedmeyer | Replicant is installed on the system partition. By default with most devices, this partition is mounted as read-only and can't be modified. |
39 | 4 | Wolfgang Wiedmeyer | You can mount the partition as writable filesystem using: |
40 | |||
41 | <pre> |
||
42 | adb remount |
||
43 | </pre> |
||
44 | |||
45 | Files under @/system/@ can now be edited. |
