Root Access After Custom ROM Flash I have flashed Custom ROM on my S3 Neo using CWM recovery.
Now after flashing the rom,I want to get the root access,so I tapped on the build number several times and activated the developer options,where I get an option of enabling root access.I enabled it for Apps and ADB.Naturally I expected root access after this,but unfortunately while checking by root checker(several best root checkers in play store) whether I got root access or not,it says no su found,and no root access.
What should I do now?Am I to Root the device again? Is it safe??
You don't need to flash the whole ROM again.You can just flash the superuser.zip from the recovery.(It's completely safe,just make sure that it's for your device). Good luck!

Here is the direct download link for updated supersu.zip from XDA Developers. Hope this helps!
