Download the official Android M Update File. Don't worry about it it is Official Release from ASUS. Then do the following:
01. Copy this file to the root directory of your Internal/External Storage.
02. Rename it as MOFD_SDUPDATE.zip
03. Now switch it Off. Enter into Recovery Mode.
04. Your installation should start automatically.
Yes! This is Official Link and Final Version. I can not give the guarantee that it is Bug Free. No OS in the world is Bug Free. If there is any Bug surely it will be Bug Free in later time according to responses received from all the ZenTalk's Members Bug Reporting.
