After recent update, Samsung blocked setuid feature in the kernel and thus renders the phone un-rootable. Since there are so many local(Chinese) apps which abuse permissions, rooting becomes a must. GT-I9502 is only sold in China, and thus I got to do it all my own.

最近的三星更新使得内核阻止了 setuid 特性，以至于手机无法在官方内核下获得 root 权限。但是太多的中国的本土应用在滥用权限，因此 root 太重要了。9502只在大陆有售，没大神可指望，只好自己动手了。

Modify CROSS_COMPILE environment variable in my_setup.sh to match toolchain path on your box. Than run build_kernel.sh

刷内核会失去保修！本人不对因本代码或 zip 包造成的任何损失负责！
