Want to root and flash lollipop on G3 F400S, need to know a few things first.

So I'm planning to root and flash a custom lollipop ROM on LG G3 (F400s and build number 10t). I've rooted and installed custom ROMs in a couple of devices before, but apparently there's a number of versions of this device. So my question is, does the process of rooting/installation of custom ROMs vary from one version to another or is the same for all versions? I've seen some tutorials for the D855 version, all I want to know is can I go through the same steps for the F400S version. Is ChupaChups ROM worth trying? Also, do I have to download a separate gapps if I plan to flash the ChupaChups ROM? Pardon the noobness fellas.
Edit: build number.

[Q] Please confirm my thought process Root/Upgrade

Hi,
I want to root and install CM13 on my H815 10c International G4.
For rooting i`ll use this guide:
http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
After root, CM sites states: For CyanogenMod 13.0 it's required that your device is running stock Android 6.0 (H815_V20A or higher).
So i need to first flash a 6.0 ROM, but which? I found this: H81520B_00 zip 1.4GB.. but i`m not sure that this will install cleanly once rooted.
Basically how to i get to 6.0 so i can install CM13?
Thanks

You can upgrade to 6.0 but if you want to flash CM after that,you have to unlock your bootloader first,then root,then flash Twrp...
The only G4 variant that can be bootloader unlocked is H815 Eu version.

Upgrading to Marshmellow via TWRP?

Hi everyone,
currently I have LG G3 D855 CloudyG3 Lollipop ROM rooted with twrp recovery and I'd like to upgrade to android mashmello.
I checked and I found stock kdz rom 30b but that means I'm losing root and twrp (i guess).
Is there an easy and safe way to avoid losing root and twrp AND upgrading to marshmellow?
Thanks
You'll find a lot of custom roms (stock one ) having android marshmallow like Fulmics 5.1, Limitless and others try searching better then this and don't let your laziness stops you from enjoying a lot of awesome features *-* good luck

Lollipop downgrade through TWRP

Hi guys, I'm currently on Marshmallow stock firmware with lineage os 14.1 as dual boot rom (I used dual boot patcher) . I have a LG g4 h815 with unlocked bootloader and twrp. I would like to downgrade my primary stock rom to lollipop (I don't mind wiping also lineage os rom). Can I use twrp to do so instead of LgUp? I need a flashable zip of the lollipop stock rom, where can I find it? Do I need to flash something else like modem or bootloader zips? Is there any custom rom for lollipop? For those wondering, I want to downgrade because both lineage and stock MM are awful for gaming, I can't get acceptable performances even with geometry dash. Thanks in advance for your help.
No one? I don't think it's a difficult question for the most experienced Android modders...
