0

The LG G4 was the first device to have received Android 6.0 Marshmallow update following the Nexus series. Although it was a couple of months ago, the manufacturer has released yet another update it’s firmware taking it to build 20B from 20A. Now the developers have been successfully on rooting the device on this firmware. Using the autoroot kernel you can easily gain root access on your LG G4 H815. This root kernel comes with the SuperSU package along with busybox and init.d support.

cile381, an XDA forum member has released an autoroot kernel that can root the LG G4 in no time on both, the 20A and the 20B Marshmallow firmware. The kernel has not been tweaked and does not contain any modifications. It is a recovery flashable zip. Hence, in order to flash this all you need is a TWRP recovery on your G4. However, note that this kernel supports the international version of the G4 with model no. H815.

So if you are on Android 6.0 firmware, then flash the autoroot kernel via custom recovery like TWRP to gain root access.
