How to get the Android M developer preview 3

It’s important to note that this is very early software and the Android M Developer Preview is intended for developers only. Be warned that manually installing Android M is not for novice users, and it’s quite possible to brick your device if you don’t know what you’re doing.

It’s important to back up any data installed on your phone or tablet before you begin since this will be lost in the process
