I have a OnePlus One mobile.
I have rooted it installed multirom on it everything was working fine .
Then i installed cyan hacker rom using twrp and multirom.
But after two days when i rebooted device into stock(internal) rom Super Su stopped working .
I was getting error "Super Su binary not found and super su can't install it).
i tried everything removed old Super Su ,flashed new one but same problem.
Tried disabling and enabling it but same problem.
But in my cyan hacker ROM when i checked i found "Your device has root access"using Root Checker app but in my stock rom it is showing as your device does not has root access.
When i am opening Multirom app it is showing you don't have root access.But in twrp recovery i have that multirom utility there and it's working fine.
I don't know what to do whether my device is rooted or not.
Shall i need to unlock the bootloader again and perform same activity of rooting again.
