Can I downgrade and root my LG G4 H818P v20h-AME-xx device? - G4 Q&A, Help & Troubleshooting

Hello first of all I have never tried rooting/downgrading a device before. AFAIK there is no way to root my h818p v20h device running android 6.0 but is there any chance to downgrade it to lollipop and root?

of course, you can downgrade and flash a .img rooted.

If you install Lollipop KDZ you can't get root, so if you want root and lollipop you should root when on kitkat and then install a bumped lollipop ROM

If I downgrade to Lollipop from Marshmallow can I root?

Hi Guys,
I tried rooting my Marhsmallow LG G4 now and I couldn't get passed the step where you type in "ID" in accordance with this guide: http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765.
I read somewhere that it was because I upgraded to MarshMallow.
Now - I want to know - If I downgrade to Lollipop can I follow the above root again and it will work?
Thanks!
Yeah.its possible. I returned lollipop from mm using LG up. Used to inject root and I'm using currently my g4 with root access.my recommend try to inject root. You don't need to open bootloader lock.

About D855 Android 6.0 Root (v30a)

Greetings guys.
I am using Hong Kong version LG G3 D855 (32GB), with Android 4.4.2 (v10n-HKG-XX).
Recently want to clean my phone and re-flash stock ROM, and I noticed Android 6.0 is out.
I downloaded D855's "v30a" firmware here:http://lg-phone-firmware.com/firmware-Lg+G3-Tutti-41.html
And searched for root method around, but looks like there are no root method available, kingroot may be working but not sure.
Is my understanding correct?
If D855's Android 6.0 is still not rootable, then I will not flash 6.0 and I will flash 5.0. Please advise, thanks in advance!

But this will replace the official recovery with TWRP (don't know the meaning), maybe I want everything stock... I think I will install 5.0 instead then since there are no similar rooting method as 4.4.2 and 5.0...
