So there has been an Android L kdz leaked for F400S on xda. Is it possible to flash it on my D855 variant? If it is possible, what's the consequences? Even if there is a high chance of bricking my phone, I'll take my chances.
It won't work unless its ported, the modem, kernel etc are all different.
There is a chance that you could hardware brick the phone by flashing a build designed for different hardware, however, I have not heard of a case on the G3 yet - but my strong advice would be to not even try.

Do not do it. Not only is there a chance of bricking your device, there's also a huge possibility that you won't be able to get it back to a working state.
There's zero benefit to flashing it, you'll most likely brick your device and the phone won't boot.
Yeah, you can't just flash the F400S KDZ without making some changes. i.e. libs,modem,kernel, etc and even then it may not work. I might be willing to take the plunge. Lol.

I know my model is D855, but there are a lot of versions with the same name, i'm not sure which one is the right for me.
I'm running 5.0 Lollipop on my G3 and wanting to downgrade back to Kitkat for root. (I don't even know why i updated to Lollipop in the first place).
Also i need to download the correct software version that i need to downgrade to (ie. KitKat), but i cannot tell the difference.
Any Help would be greatly appreciated, Thanks!

Do some research into the LG Flash Tool.
As long as the software is compatible with D855 you''re good! There can be different builds such as (last 3 digits) 10r or 10c, but they are essentially the same thing with just minor changes. If it's cleared for the D855 you'll be good.
There is setup that must be performed on the Flash Tool, so make sure you follow the steps in various guides attentively. I would tell you what you need to do, but I cannot remember every detail.
A lot of the guides for downgrading will be found in the same areas as guides for rooting because downgrading must be done in order for some root methods to work.

Any kitkat build for the D855 will suffice. I remember doing TOT, but I'm not familiar with Kdz so I cannot answer that.
Hey guys,
Does anyone know how we can get the rollback number on our devices? I was reading this thread here:
http://forum.xda-developers.com/g4/...wngrade-g4-t3197675/post62748057#post62748057
I guess you need to know your rollback number to do a KDZ becasue there is a chance of a hard brick. I tried the numbers highlighted below but it didn't work for Verizon. Anyone know how we could get this information?
waylo said:
This was not written anywhere specifically on the LG G4 forums that I could find. But every flash-addict needs to be warned. It is something you want to know before you continue tinkering.
Several users (myself included) have made the unfortunate mistake of attempting to downgrade their bootstack (for various reasons) to a former version.
DO NOT DO THIS (at least for the USA T-Mobile H811 version, and possibly other USA versions, per @autoprime)! It will result in a hard brick! Specifically, this results in the "Qualcomm QDLoader HS-USB port ( 9008 )" error. Connecting your phone to a PC will pop up with this active connection, but nothing else. There is no download mode. There is no publicly available fix as of yet.
This WILL happen both through KDZ restore as well as flashing bootstack .zips.
Yes, an official KDZ image can BRICK your USA phone, if you try to rollback.
This is in stark contrast to other manufacturers (i.e. Samsung), where the attempt to flash an older bootloader/modem/radio will simply fail, but your phone is not bricked.
I have conferred with @autoprime, who confirmed that with each OTA firmware release (on T-Mobile it was 10H, and now 10N), the version # increments. Flashing a lower version # will result in brick.
I have searched far and wide for a DIY fix. Without the proper firmwares in the right format, as well as the right flashing software, your phone is done and must be sent in for LG repair.
To check what antiroll-back version you are on, input this sequence in the dialer (T-Mobile and ATT) and scroll down:
*#*#244773825625#*#*
Flashing a bootstack version less than this # (through KDZ or zip) will brick the phone. You are free to flash anything equal or higher than the version listed.

If you are still on the original software version 10b, then you have v0. If you took the OTA (or flashed the KDZ) to 11a, then you have v1.
We have a new OTA out now, 12a. I'm not sure what version that one is, but I'm willing to bet it is v2, and you will not be able to rollback if you install it.

Yeah right now I'm stuck with 11A and I'm not sure what I should do. Even though my phone sucks the way it runs, I'm gonna hang in there and wait a couple weeks. See what comes out of 12A.
Well I don't believe there is a way to check or there is a known way of finding it yet. Apparently there is an APK app that reads it. Perhaps we can rip it from another rom and access the APK via the same method we do for accessing the Themes (using a launcher to do custom shortcuts).
The inability to KDZ back to original software is ridiculous. Just like 12A and the broken notifications. How stupid is it to force broken updates yet make it impossible to go back to previous backup/software. I am half tempted to just take the 12A update and force Verizon to give me another phone just to emphasize my dislike for their method of locking the system down.
I got my lg g3 fixed running v30b and i rooted it got all the lg g5 apps but i dont have custom recovery so i cant flash a rom and everytime i replace the framework and system ui from the lg g5 it gets bricked and i have to flash a new kdz so can someone help me? Please
what the.... why are u trying to port framework without a custom recovery? it's not hard to install there is a program called g3 autorec that you can find online (not on playstore) that will install an old version of twrp for you and backup your current recovery, just make sure u get the right one, there are diff versions for diff g3 models.
Motherboard doesn't support android kitkat/lollipop partitions
Now thats my problem my motherboard doesnt support android kitkat or lollipop so if my use autorec my motherboard is fried thats what happened last time when i tried to downgrade to kitkat i want to get a working port of framework and systemui and maybe lge-res so i can get a taste of the white theme from lg g5 that works for all variants after that i'll use root explorer

First downgrade to kitkat (with a d852 tot or kdz), then root, then use autorec. After that you can flash what you want.

Pretty sure you just did something wrong. You say your device is a D852 (from your software version), the fact that a D852 kdz or tot is not compatible with your D852 because it was manufactured in 2016 is very unlikely. You also said that your motherboard was "fried" when you tried to downgrade (which is again, VERY unlikely), if your motherboard was fried you phone would be dead right now.
"now i want you to ...(blablabla)", don't ever say that if you want to get some help.

I said it was unlikely that the kdz or tot wont work because your phone was manifactured in 2016, not that your phone was manifactured in 2016.
That being said, I guess you don't understand really well english and that's causing some misapprehension.
I was not rude or anything, I was just trying to help you.
Have a nice day, I wont answer anymore.
I strongly recommend this thread is closed.
I'm trying to downgrade my G4 from marshmallow back to lollipop. My anti-rollback # is 2, and according to this as long as the anti-rollback # is the same on both the installed version and the kdz, flashing the downgrade doesn't hard brick the device.
So far I've been unable to either find one, or clarify if one exists for my variant or not. Can anyone help? Thanks.
In any event ...

In any event ... if you do happen to find an LP stock image to try, make sure you use LGUP-NEW (https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803) to downgrade to the stock Lollipop image as it should throw throw up an error regarding the anti-rollback version roll back and not proceed with the rollback, thereby avoiding any brick worries for you ...
You may have to do a bit of trial and error but it would help if you post your exact software version that you are on now for anyone to assist you in at least pointing you in the right direction for LP kdz's to try.

Oh, so LGUP-NEW pretty much let's you throw any kdz at the device and if it would have normally bricked the device, instead it comes up with an error? That's pretty neat.
My specific software version US99125a, and if it helps at all, my end goal is to hopefully root my device.
Well, not any old kdz ...

Hey guys,
As the g8s is falling in price a lot and has good build quality, I was thinking of picking one up. Sadly the almost non existant updates of LG hinder me here.
So I was wondering, did anyone try to get GSI working on the European g8s, which can be bootloader unlocked? If so, how is the functionality?
Thanks.
same here, anyone tried it?
Not possible because there is no TWRP and also no Custom Roms

Hmm, as far as I understand GSI, it works on project treble enabled phones. For this you don't necessarily need twrp and most of all device specific custom roms. You can theoretically flash a generic GSI on a bootloader unlocked phone with fastboot. The question naturally is, if it's usable than on this specific phone.
But it appears noone tried that with the g8s and the price has gone considerably up again... At least where I live
it would be a horribly stupid move to flash a GSI on a phone without any working recovery - if the GSI fcks up something you're stuck with a phone that might be bricked forever
doubt anyone would want to try that with their flagship phone lol
If only you would know that you can flash a stock kdz with lgup in case it goes sideways. The dll is available from this forum, lgup as well and the kdz from LG fan club.
Yes,exist https://forum.xda-developers.com/t/rom-lineageos-18-1-for-lg-g8s-thinq-betalm-wip.4219111/
