Downgrade from Android Marshmallow to Lollipop

Android M update in Asus Zenfone Series is a great thing. Through which I could not find any major update. As I Expected that Asus will include RAW Image feature but no, They didn't.

Meanwhile, a lot of other users are experiencing problems like Battery Drainage, Camera problem etc. So I decided to make a tutorial on Downgrading.
I have tested this on my Zenfone 2 Laser ZE550KL and it works.
I have Downgraded From Version V21.40.1220.1615 to 1.12.40..349


INSTRUCTIONS:

Download Your respective phone FIRMWARE from Asus Website.

1.  Put that into phones External Storage
2.  Turn off the phone and go to recovery mode.
3.  Press on "Apply Update from SDcard" 
4.  Now Wait for a while it will complete the installation.
5. If it shows any error then move back to older version of Downgrade firmware.

That's all guys. I hope you have done the above tutorial successfully. If you found any problem then please comment below.
