I think the only possible root method is Chainfire's systemless root.
But you need to unlock the bootloader (warranty void) and install TWRP. But as always read about it:

I am trying since several days to somehow install TWRP. And nothing works so far for the H340N .

My next idea is to downgrade again to v10h, then try to root (via kingroot i guess?). Change from kingroot to SU, then install Flashfire. Through Flashfire you should be able to install a OTA Update, such as Android 6.0 without loosing root. And then when you have root and the option to OEM-Unlock you should be able to install TWRP through the TWRP-Manager app. Or am i wrong at some point?

Would be nice to just have access to fastboot mode in marshmallow though...

I've seen some people with LG g4 with the same problem on MM. They can't root withou tunlocking bootloader. That sucks balls. Seems to be that the root needs to be on the boot partition, which is inaccessible without unlocking bootloader. The thing is, will OEM UNLOCK unlock bootloader? That's it? :/

Normally you can do "adb reboot-bootloader" and then "fastboot boot twrp.img".
But "adb reboot-bootloader" does not work with V20a, it just starts a normal boot.

I would greatly appreciate if someone got a solution to root the H340N with android 6.0. Kingroot doesn't seem to support Android 6.0... :/

Regarding the "systemless root", anyone tried it with this phone and Android version?

Hi,

I successful root my LG-H340n marshmallow a few month ago. It's a mix of several tips found on Internet.

Using USB download mode and "LG Root Script v1.3", it's possible to have an access to partitions and change recovery partition to TWRP. Using the same way I change also aboot partition (with one compatible with twrp).

After TWRP installed, I use it to install SuperSU systemless root.

And It's magic :) now I can use my SD card and Apps2SD to create symbolinc link to my apps and free internal memory !

I have some notes and links, if you want, I can write a tutorial.
