ERROR while trying to install gcam on my redmi note 4.. Need help!!

[shivaprasad.26071997]

Hello guys,
Today I tried to install gcam on my Redmi note 4..
I found both gcam mod apk and camera to api enabler and followed the instructions,
But I encountered black screen issue....
So I searched for solutions and found a thread with the same problem...
It had a flashable zip file as solution.
I mistakenly flashed the file without realizing it was for redmi 4 device (not redmi note 4).
and my camera stopped working and showing this error...
