well my way would be upgrade using LGUP and 20i KDZ LP and 10n are antirollback V2..20o its v3 so you cant go to 20o and downgrade only if you stay on 20i and then go back to 10nLP...
heres intructions for KDZ 20i and unlock preocedure.. youll need minimal adb.. unless you have sdk studio..

i didnt make myself clear LOL don upgrade to 20o unless you want to get stuck its 0in there...as is antirollback version V3.. so 20i and 10n are V2 you can upgrade or downgrade as long as you stay on MM20i or LP 10n doing so 20o will brick phone if try to downgrade....
when you connect phone make sure you tick allow connection on screen and another option for adb.. then you are all set

but youll be stuck there.. until if someone can make bypass antiroll back or untill if nougat hits G4.
Hello. I have a rooted, bootloader unlocked and twrp installed lg g4 h811 20i. I want to know if i can use the official ota method to upgrade to 20o safely? Will it cause bootloop or brick? Coz my phone is rooted.
Do i need to flash stock unrooted kdz and then upgrade or i can just use the ota method safely?

from 20i to 20o ota or dirty flash will give you camera problems and no sound.... the best way is ...
download 20o KDZ then use LGUP. using the refurbished option so it wipes everything.. once you are on 20o then preoceed to.... install twrp and root.... there a guide in the rom seccion.. also flashing 20o will put you on antirollback V3 so you cant downgrade or youll brick phone... if you want freddom to go from LP to MM stay on 20i MM and could downgrade to 10n LP.

you need KDZ and LGUP. look here. i know 10n its lollipop
20i its marshmallow and latest its 20o. are you planing on rooting and use twrp.? if not you can only root 10n with locked bootloader. so you need to stay on 10n.. or upgrade to 20i MM. but do not flash 20oMM and go back downgrade to 20i- or 10n it will brick phone.
you need drivers-LGUP and KDZ. i think in the links you find everything

you have LG drivers.?? also LGUP doesnt work on USB 3.0 try other ports in computer or another compute and see if it detects phone.
I want to share my experience with you guys.
So I've updated my LG G4 to ZVC firmeware, and read that is not possible to root it, and no unlock chances therefore. And since is really difficult to make downgrade once you've reached this version, I was totally freaked out that I wouldn't be able to unlock it.
And thanks to some brave community fellows that tried this method, I felt encouraged to do it.
In order to unlock your network, you have use a Global rom for ZVB firmeware, YES, it also works for ZVC. Said that, I have to tell you that this it's a risky method, and if you don't properly follow steps, you'll hard brick your phone, so do it at your own risk.
Here is the link:
http://forum.xda-developers.com/spr...-mellowmallow-debloated-60fps-camera-t3358340
Please, make sure to thank the OP and developers. Buy 'em a beer or something
Going from ZVC firmware, did you have to deviate at all from the instructions at that link you provided? Or did you get success following it exactly as written? I think you convinced me to take the plunge.
(Well, also to be fully honest, now that the V20 is available, I'm more willing to take risks with my beloved LG G4 in the secret hope I might break it and justify the expensive upgrade as being forced into it)

Hi, just go to the link and follow the instructions there, you'll be alright.
I made this threat since everyone was confused about this firmeware version, and I wanted to share with you that YOU CAN UNLOCK the network once you are in ZVC as I DID. So no worries, you'll be able to unlock the sim from your LG G4 ZVC, using the ZVB procedure.

In this particular case, just Install the ZVB Global rom (Even if you have ZVC like me). No downgrade needed. Once you've installed the ZVB Global rom (FOLLOWING THE ALL THE STEPS of the original post) you'll have your phone UNLOCKED and running ZVB.
In other words, it is not a downgrade process (Although you'll be downgrading your phone from ZVC to ZVB) NO ADDITIONAL STEPS for it, do like your device was on ZVB and please, don't skip any step and you'll be fine.
It worked for me, it will work for you. Good luck

Did you use LGUP to downgrade to earlier versions first? If I remember correctly, there might be a chance to use the ZVC tot file to revert from ZVD to ZVC?

ive never dont the method but can descibe it to a T
on marshmallow sprint closed the send command port on g4 so a very dangerous technique in opening it as follows kinda. you open lgup and flash some tot dont know which one but as soon as it hits 9% this is when the send command port gets opened You have to unplug the usb cable exactly rite time and the send port stays open then u can dd in the system image.
now it is dangerous can hard brick device but im digging up the links now

10n and 20i antirollback V2. you can flash this 2 if you stay there.. 10 is lollipop and 20i is MM.
20o-20p-20q-and latest 20R is antirollback V3 you can switched to any onf this once you flash 20o or higher.
you cant unlock bootloader if you are in lollipop.

i have not seen this on G4 in G2 yes alot of places would say it was d800. in stickers and all but the motherboard were replaced with anothe variant. so a phone put up togethe of othe phones parts..

i see. i was helping there as well. but since i have not had USBHBULK and since then there was no way to fix. i see now they have some thread about unbricking.
i had that same brick on LG G2 but running KDZ. fix it on G2.. i think here is a different way with G4.
i wonder if that is the same situation. changed motherboard. and am not really sure if motherboards can be use in different variants.. only way is to physically see it.. but since you have warranty. then you are good.

am puzzled... i know in G2 they did that.. so could that be the case here.??
that doesnt help.. that app.
as i already told you. in G2 they can change IMEI and model number.. outside of phone would be a at&t housing then removing phone apart would show other model number for behind battery housing.. so they can edit software it could say d800 in about phone and version , ect d800 housing . but motherboard would be sprint...
guys am just sharing what i have seen in G2.. am not saying its same way.. its just my opinion and my toughts . what else could it be.??
nooo that program does not help. they can edit software info.. but not motherboard printed model.. what am saying is.. to make sure you have a real h811 in case they are building phones from other variants.
is to open phone and physically see the motherboard printed number.
