This means no more rooting is possible, at least not anymore in the usual methods. Your SuperUser will tell you it will have granted access, but it's neutered on the kernel level.
There is the exception of allowing /system/bin/pppd to gain root access so somebody will want to maybe replace that somehow to gain it as an entry-point. Somebody will want to check that.
This doesn't apply to custom compiled kernels which disable this config option.
I've tested it and it's true.... I9505 STOCK Kernel for new builds MDM/MDN has been LOCKED as well....
My solution is to use Kernel from builds up to MDF and include it into CF-AutoRoot package and it WORKS like charm... (Future proof..)
BTW, they have changed something in system.img.ext4 as well!! Checksum added or something like this, if you re-build it, whole integrity is broken... SYSTEM IS LOCKED!!
CSC is impossible to apply usual way, I've implanted it into system and modified to achieve HD Voice support on all networks.. NOTHING can be added to it afterwards..
