How to get the basic OS on my Zenfone2 500KL


Broken In
Hi All,

I am using zenfone 2 550KL. It got updated many times with newer version of android. Currently the version of android is in my mobile is 6.0.1.

But now the touch and other functionalities are not working fine. Even when phone rings I am unable to pick the call. So I want the OS which was came with my mobile initially, when I bought it.

So please suggest me any tool, software or utility to do so.

[I have done the hard reset many times, but didn't make any changes in OS]
