Hello. I have an LG G4 US99122a running on MM 6.0. I wanted to root the phone but I have researched that currently bootloader is locked on this model and cannot be rooted. Should I downgrade it to it’s stock rom running LP 5.1 and then rooth it from there? Any suggestion is much appreciated. Thanks.

depends if phone can be downgraded.. some phone have antirollback.. example i have h811 and if am on lastest 20pMM its V3 so i can only downgrade to MM 20o... if i was on MM20i i could downgrade to LP 10n as 10n and 20i are V2.. so you need to ask what antirollback version your phone is.. some can.. and some phone cant be downgraded after you on specific firmware... try the hidden menu and check the software then scroll down and it says wich antirollback you are on. otherwise youll hard brick phone.

That i do not know i have t mobile. So now you know you have antirollback 2 ans you have verizon g4 so i guess its best to ask in the verizon thread section and ask. As i dont know thieir firmwares and antirollbacks.. ?

Yes its can't be rooted while on MM 6.0. I also cannot flash through recovery as its bootloader is locked. My only option is to rollback to its stock firmware on LP so I can root it. Any advise?

One has to wonder if anti-rollback is permanent on the device or not, even with bootloader unlocking and or root access.
Root is now quit possible with the new vulnerabilities found. Now it seems to be a wait and see game if there are any devs that care to tackle certain G4 models that cannot be self-rooted yet. The dirty cow code is out...so yeah.

Well, I thought buying this phone would end my terrible relationship with ATT's Note 4 for good... Hell it's even an H815 for christ sakes....
But it seems like it can't be rooted on MM due its bootloader being locked :/
Yes, I did try using the official unlock tool but, as some of you know it doesn't work for the Taiwan version (Just my luck).
However, I looked around and saw that the Lollipop version can have root/twrp installed WITHOUT unlocking the bootloader.
In conclusion, my question is............. will I be able to downgrade from MM to Lollipop?

From what I know the H815 model can be unlocked. But I think it's only the International one. There's an unofficial unlock in the works, just look around on the forums, haven't been that interested 'cause I'm rocking an International model

I tried using the Official unlock tool but, it doesn't support the Taiwan version, even though it's an H815 :/

Lollipop, or LP, is version 5.1. Just look at the KDZ files that are Android 5.1

20-i its tmobile right if yes then read the reply and click the link.
You should wait for the OTA for 20-0 because once rooted OTA will cause bootloops. But if you dont wanna upgrade then follow below link

This is very strange because I have H815, not 811
I unlock bootloader via official Lg page
Install TWRP also no problem
But when I wanna install coustom room, phone bootpool and I must use LGBridge to back v20i

I was a recent victim of the infamous boot loop brick. Luckily the phone was still under warranty and I received a new phone. Unfortunately the new phone is AT&T, Android 6.0, H81021y. Can I simply downgrade to the rooted AT&T Android 5.x H81010o image to regain root?
anyone?

You have to checked your antirollback version in 21y, if im not mistaken 10o antirollback is v1..
If your software in v1 then you can downgrade but please make sure of it or you wil hardbrick the device

Come back when you have unlocked your device:
Unlock and root is not the same!
You need an unlocked bootloader for twrp.
Bootloader of H818 cannot be unlocked yet and maybe never will.
That means no twrp for you.

As said just one post before: you need to have an unlocked device first! Write LG an email and sign the online petition to let them unlock your device (0.05% chance that this will happen) or wait and hope that someone finds another way (1% chance that this will happen)

Hi,
I have an Lg G4 h812 with H1220z software version. Now i have a couple'a questions someone needs to answer.
Can and how do i downgrade and root using a h81210b image (http://bit.ly/2q2Rbve) without anything going sideways?
And can you upgrade to MM keeping root?

you need to know your antiroll back. you get there by using the hidden menu then software.. if its 0 then i beleive its okey if it has a number like tmobile like am on latest 20v its antirollback V3 and lollipop is V2 so i cant.
once lollipop rooted and update to MM no you cant keep root.

You should first and foremost be posting in [Canadian Guide] - Complete Source for the LG G4 H812. Linux VM/Root/Tools&Files at https://forum.xda-developers.com/g4/general/canadian-guide-complete-source-lg-g4-t3212449
Everything you are asking is covered there.
The statement by Minto107 in post #4 here about 99% of H812's having anti-rollback is factually incorrect - I had an H81220X before rolling back to h81210N and you will note in the Guide I Linked above, almost no one cites having anti-rollback. Now, with that said, I cannot comment on the H81220Z version. It is possible that it has an anti-rollback provision.
In any event though, if you use LGUP-NEW (https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803) to do the roll-back, it should throw up an error that indicates a rollback version problem. It is the only flash/rollback tool you should use in this case.
