OnePlus 3 Smartphone Launched Together With Source Code

Most smartphone manufacturers will drag their feet to release GPL source code, unless you go with Google Nexus or Android One smartphones. OnePlus is another exception as they have just launched OnePlus 3 smartphone, and released the source code the very same day as the hardware launch.

The phone ships with a pre-applied screen protector, a Dash charge Type-C cable and charge adapter, a SIM tray ejector, and a quick start guide. OnePlus3 runs OxygenOS based on Android 6.0 Marshmallow.

This brings me to the software release. I understand that while OxygenOS itself is not open source, you can still retrieve the open source part and some extra binaries from the phone to build and possibly modify the image yourself, as explained on OnePlusOSS github repo:

Retrieve the open source code:

repo init -u git://github.com/OnePlusOSS/android.git -b oneplus3/6.0.1 repo sync

1
2

repo init -u git://github.com/OnePlusOSS/android.git -b oneplus3/6.0.1
repo sync
Retrieve some close source libraries from the phone after rooting it:

pull_library.sh

1

pull_library.sh

This will create a “vendor” directory that you need to copy to the build directory
You can then build the firmware:

. build/envsetup.sh lunch msm8996-user make -j8

1
2
3

. build/envsetup.sh
lunch msm8996-user
make -j8
and flash it with fastboot:

adb reboot bootloader fastboot flash boot boot.img fastboot flash system system.img

3

adb reboot bootloader
fastboot flash boot boot.img
fastboot flash system system.img

OnePlus 3 sells for 399 Euros. More details can be found on the product page, and if you are interested in hacking the device (rooting won’t void the warranty btw), you may want to check the dedicated forum on XDA developer.
