Although the official update for the final version of Android O has not been confirmed, at the Google I/O Developer conference, Google has announced the second Developer Preview of Android O. If you feel interested with this version, here’s how to download and install them on your device.
Steps to Install the Android O Developer Preview
The Android O Developer Preview images were available for the Nexus and Pixel devices including Nexus 5X, Nexus 6P, Nexus Player, Pixel C, Pixel, and Pixel XL. However, you should take note that the Developer Preview is not recommended for daily use, so it may not be stable.
You can download the system images from here, and then flash it to your device by following the step-by-step guide.
How To Flash A System Image:
- First, download the system image for your device, then unzip it to a directory.
- Next, plug your device to your computer with the help of the USB cord.
- Boot your device into the fastboot mode by doing one of the following methods:
- First, use the adb tool: When your device is powered on, enter a command line:
adb reboot bootloader
- Use a key combo: Power off the device, then turn it back on and immediately hold down the relevant key combination on your device.
- If it’s necessary, you should unlock the device’s bootloader by using the following methods:
- If you are using a Nexus 5X or Nexus 6P device, update your fastboot tool to the latest available version (>=23.0.1), and then run this command:
fastboot flashing unlock
- If you are updating an older device, enter the command:
fastboot oem unlock
- Now, go to the unzipped system image directory.
- Now, execute the flash-all script to install the necessary bootloader, baseband firmware(s), and OS.
Once the script is done, your device will reboot. You should now lock the bootloader for the security:
- First, start booting your device in fastboot mode again using the above method.
- Enter the command line
fastboot flashing lock or fastboot oem lock for old devices.
Locking bootloader will remove the data. After locking the bootloader, if you want to flash the device again, you should run fastboot oem unlock again, but it will wipe the data again.
