How to Install Android O Developer Preview on Nexus 6P

The first Android N Developer Preview was released about an year ago, so it is the perfect time to be talking about the first Android O Developer Preview.

Just like we are used to, Google has unexpectedly introduced the latest Android iteration, but I see no person complaining about that. If you have the Nexus 6P handset on your hand, then there’s a build of Android O available exactly for you to install prior to the update’s official unveiling.

Let me though tell you right from the start the fact that this is a very early build of the Android OS, so it may come with bugs, glitches, and overall performance issue. If that doesn’t scare you at all and you see this as a challenge, then don’t hesitate to keep on reading.

Get ready for the procedure:

• Flashing the developer preview will completely erase your device, so it’s mandatory to make a backup before proceeding;
• Your device’s bootloader needs to be unlocked;
• Verify that “OEM Unlocking” and “USB Debugging” are enabled in Settings->Developer Options;
• You will need to have ADB and Fastboot tools on your Windows computer.
