Chainfire’s systemless root is now allowing automated boot image patching when you install. This basically means that you don’t have to upload specific boot images for smartphones and tablets because the zip installer for SuperSu will install in systemless mode and patch the boot image automatically. This will only work on Android 6.0 and Touchwiz based on Android 5.1 for now. Keep checking the compatibility of the Beta on the forums.
The installation is pretty simple this time around, all you have to do is reflash the stock ROM when you move from normal SuperSu installations in the /system partition. Users with a previous systemless installation will also have to flash the stock kernel before flashing this Beta zip.
Official dev notes on the beta:
“The boot image patcher currently only supports gzip compressed ramdisks and the standard Android boot image format. Some devices do not use the standard format, and many custom kernels use a compression other than gzip. A backup is made (/data/stock_boot_.img.gz) of the original kernel before patching it.
… The script inside the ZIP usually contains a lot of specific docs, but for systemless I have not written that part yet. The sukernel tool that does a lot of the patching magic is very chatty, telling you exactly what it does and how. In TWRP you can see it’s output with “adb shell cat /tmp/recovery.log” after installing the ZIP.”
Chainfire assures users that the future updates for systemless root will be much easier to use , so the steps are not very hard to complete, considering this is a one-time setup. The dev has tested the beta on some flagshipy devices like the Nexus ones (on Android 6.0 and CyanogenMod 13), and Samsung Galaxy S6. You can try it for yourself, but don’t forget to backup everything before you start baking your phone.
