Root Nexus 5 on Android 5.0 Lollipop

The Android 5.0 Lollipop update comes with enhanced security at kernel level with SELinux set to enforcing, and while this is a good for the Android ecosystem, the change to SELinux, however, also breaks our conventional ways of rooting an Android device. Setting the SELinux back to permissive fixes things up, but that’s not possible without modifying the boot image (kernel). Also, having the SELinux set at enforcing is preferred for the security reasons. So considering all this, our legendary developer Chainfire has provided modified kernels for Nexus 5 with SELinux set to permissive only to the limit of rooting Android 5.0, not system wide.

So what you gotta do root Nexus 5 on Android 5.0 Lollipop is flashing the modified boot image first, then flash SuperSU zip via a custom recovery (TWRP recommended). This is a quick fix by Chainfire and he may find a better way to root Android 5.0 builds without the need of modifying kernel (boot images). For now, this is the best way we’ve to root Nexus 5 on Android 5.0, Chainfire’s custom kernels set SELinux to permissive only partially, retaining much of security from the default enforcing status.
