Google recently launched the developer preview of Android O. Being a developer preview, the user might face some bugs but don’t worry it is very much stable. With the launch of Android O, Google has introduced some great security features with many cool UI changes as well. The developer preview is currently available on Google Pixel, Pixel C, Nexus 5X, Nexus 6P but soon more devices will be added to the supported list. Note that your device need not be a rooted device, as this is a stock firmware so it can be installed without root access. First of all, you’ll have to confirm that your device supports Android O or not. Google have made an official announcement about the supported list of Android O. So before moving on, go to this link and check if your device is supported and if it supports your device then you are good to go.

It doesn’t matter which device you are running on the drivers as it can be used all around.

- Once the device is powered off, go into the fastboot mode.
- To go into fastboot mode, press and hold the volume down and power off button together. The device will vibrate once.
- This screen will show up once the device enters into the fastboot mode.

- Copy the required files from firmware directory.
- Jump to ‘firmware’ folder and copy ‘bootloader-YOURFILENAME’, ‘image-bullhead-YOURFILENAME’ and ‘radio-bullhead-YOURFILENAME’. (YOURFILENAME: will be according to your device).
- Paste the copied file in the fastboot directory.
- Now install the USB drivers.
- Now open CMD
- Jump to the ‘fastboot’ directory and open cmd, pressing the shift key and right mouse click together will give you the option to open the command prompt.
