Build
lunch <BUILD-BUILDTYPE>
All build targets take the form BUILD-BUILDTYPE, where the BUILD is a codename referring to the particular feature combination.
BuiltType | Use |
|---|---|
| user | limited access; suited for production |
| userdebug | like "user" but with root access and debuggability; preferred for debugging |
| eng | development configuration with additional debugging tools |
For more information about building for and running on actual hardware, see Running Builds.

Connect to the board
Connect the USB-C to the HiKey-960 board and power it up.
adb kill-server
adb start-server
adb shell
You should be able to get a shell prompt.
If you get the following error, you may need to install an additional package
error: insufficient permissions for device: user in plugdev group; are your udev rules wrong?
See [http://developer.android.com/tools/device.html] for more information
sudo apt-get install android-sdk-platform-tools-common
This package includes the udev rules to make adb work properly.
Flash device
Select fastboot mode turning ON switch 1 and 3 (for details, refer to the HiKey960 user guide).
Power the board.
Flash initial images:
> cd device/linaro/hikey/installer/hikey960> ./flash-all.sh
