Android M for Asus Zenfone 2 ZE551ML / ZE550ML

Asus released Android M update for Asus ZenFone 2.

Finally, Android M is available for Asus ZenFone 2. It's been a long waiting for the user of this device.
Unfortunately, This is the only device that is facing big issue with Android M. 
Asus have already know that publicly releasing Android M `is not safe because a bug is always there in the os After beta testing too. In the END of Q2 Asus started releasing updates for its Laser devices and finally released Android M for few users to check the stability.

After few days they saw that the OS is having huge problems ie: Battery drain and ram leak, The battery drain issue is still there on other devices like Ze550KL laser, So Asus decided to bring down the update procedure from OTA and also removed ZIP files from the website and give the reason about server issue. After few days they again uploaded the ZIP files into the server. The new ly uploaded files seem to be modified because previous Android M-files are little smaller than this new one. But still, there is no Update log in Zen talk.
After all now, Asus rolled out Android M for ZE551ML / ZE550ML and I hope its the stable version.
More information about the update is below. Its the beta one but final version will be listed here soon. Keep checking this post.
