It is speculated that this will be Android 5.0 and also be called “Lollipop”.

Step 1a (optional only do this if your bootloader is locked)

Step 2: grab those images from google
Step 3: if you are running windows extract the image files and start the flash-all.bat or manually flash away heres a guide on the instructions (look at method 2) XDA guide on flashing images
