Lollipop downgrade through TWRP - G4 Q&A, Help & Troubleshooting

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...

[Q] What KitKat can you suggest to me ?

Hello
I have an D855 with TWRP, Cloudy 2.5 & Gabriel kernel install on my phone and the kitkat bootloader for not necessary have TWRP bumped.
I would like to know what is the last KitKat ROMs (AOSP/based stock/AOKP) and if its possible, know what is the last modem that i can install on KK ROM..
Why i want to downgrade android version ? I have test all needed fonctionality that i want and i think LP is pretty bad (its my opinion..), and i have a secondary question: about the battery life on KK, its really better (with any ROM) on LP or its depend of the kernel & ROM (KK or LP) ?
Thanks.

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

Marshmallow modem with lollipop rom and lineage OS 14.1

Hi guys, I'm running lollipop stock rom as my primary rom and Lineage OS 14.1 as my secondary rom (I used dual boot patcher to achieve that). The problem is that everything related to sensors (as gyroscope and camera) doesn't work on lineage because (I think) the lollipop modem is outdated and incompatible with this rom. Will flashing just the marshmallow modem.zip fix the problems with lineage? Will lollipop stock rom keep working with the marshmallow modem? Do I need to flash also boot and or bootloader too? Thanks in advance
Please guys, just answer if lollipop stock rom will work with marshmallow stock rom's modem and bootloader.

custom rom with stock kernel?

Was wondering if I flash a 5.1 rom with an untouched stock lollipop boot image onto my G4 what the outcome would be?
Is there any lollipop custom rom that this would work with? I have tried this on my locked lg g4 BTW and no dice

1)
The 5.1 Rom is the stockrom for the G4 Series came out in 2015.
You can flash a 5.1 and it will be run, why not? But MM (6.0) is more G4 friendly, works more fluid...
2)
The only thing you must looking for is the correkt Modell, H815-H818 and so on....
What Android is on the G4 now and what is locked on it? The Bootloader or have a Provider Lock..?

It's a H815T with a locked bootloader and I root all my devices
I was hoping that imperium or some other stockbased rom with notable differences would have released a 5.1 version, but I think they started on MM. I actually tried to flash cm12.1 then my stock boot image lol. Had to wipe and restore plain old Genisys rom
It's network unlocked and I use Twrpinfish by @steadfasterX

My wish is at least to have a more 'stock android' ui and ability to theme (cmte,etc)
If I could boot a cm12.1 rom it would awesome :highfive:
