Cannot install update cm13 ,I have installed a custom kernel

I am on a cm 13 ROM ,I installed custom kernel ( Nemisis Kernal)
Now I am not able to update cm13 ROM
I had an error Asus.trustzone(xx"xxxxx)==1;
Status 7 error
I removed that line form the the updater script file and installed the updated
It installed successfully, but rebooting into bootloader
After some research
I found that the boot.IMG was not flashing
So I restored only the boot.IMG from a nandroid backup
It was successful, and booted system
Most of the apps were working.
Camera is not functioning as if it is not detecting camera
I even tried to remove cynogenmod completely and then
Install cm13 latest release newly
It didn't work
I tried to sideload the new update
It also didn't work
I think I have to port the boot IMG for camera fix
In the tutorial
They said to replace the zimage file from stock boot to port boot IMG
Copy the init.rc
# Camera
......
Section and paste in port into.rc
But I could not find any # Camera section
In some tutorials the asked to edit init.project. rc
I searched all init.xxxxxx.rc files
I could not find # Camera section
Can any one help me !!!!! :crying::crying::crying:

Please help me to port boot.IMG to my rom
