[T-Mobile LG G6 Guides, News, & Discussion] stoneworrior:
I had the latest version. I decided to unlpug the phone and allow it to die then charge it to see if it restarts. That worked and the phone is working normally again so I'm going to give it another try as soon as the phone is fully charged.

I had the same concern being on 20g myself so I just used the unmodified version of lgup to downgrade to 11g the start the process just to be safe. Step one worked with zero issues using 11g

---------- Post added at 09:08 PM ---------- Previous post was at 09:05 PM ----------

My phone was stuck in download mode so I finally decided to let the battery drain then recharge to see what happens. After the phone was dead I plugged it in and it came to life and booted up on its own.

---------- Post added at 09:18 PM ---------- Previous post was at 09:08 PM ----------

Also no where in the instructions does it say what to do with the TWRP file if NOT on 20a. The instructions only say to download it but am I supposed to put it in the root drive of the phone storage running 11g? Root on SD card? I can only assume the commands for git pull TWRP and install it automagically ?

---------- Post added at 09:53 PM ---------- Previous post was at 09:18 PM ----------

I just tried again on the same computer I started on and part 2 went smoothly this time and I now have a rooted LG g6. The first time had to be some sort of glitch and the computer wasn't recognizing my phone for some reason. I let my phone die completely so I could get out of download mode and all went as expected this time. Thank you for the rooting method and instructions ?
[T-Mobile LG G6 Guides, News, & Discussion] vampercy:
Yeah It's easy if you read before do anything personally I read all the instructions. Like 30 times and then do this.

Happy to be free

---------- Post added at 12:03 AM ---------- Previous post was at 12:00 AM ----------

I recommend you to do this from 11g. downgrade. And try again

Actually when I was stuck in download mode I was doing everything right I just got panicked because it's the first time I follow progress like that now I have pie ROM and root thank you for help and I didn't let my phone drain it stayed for like 20 minutes then rebooted itself
[T-Mobile LG G6 Guides, News, & Discussion] stoneworrior:
What pie rom are you running? Any bugs how do you like it?
[T-Mobile LG G6 Guides, News, & Discussion] ouaelat:
Running havoc os 2.6 lg g6 pie ROM , feels so smooth I think I like it better then Oreo I feel like I have different phone now . bugs : camera back not working , I don't how to use the fingerprint cuz it's not in options at security and lock I think it's removed ..all other things working fine and so smooth butbi think I do a clean flash it'll work oh 4k is not in there also ..
[T-Mobile LG G6 Guides, News, & Discussion] stoneworrior:
The fingerprint scanner is common when coming from a nougat Rom from what I'm reading. You need to flash the Oreo bootloader files then flash the pie ROM for fingerprint to work. The camera is the same everywhere on pie. I downloaded the Google camera app from the play store it works fine. I have the Pixel experience ROM and everything works except the camera that's why I downloaded the Google play version. I'm very happy on pie ? sorry I know off topic. Just thought I should mention the Oreo bootloader for you ?
[T-Mobile LG G6 Guides, News, & Discussion] ouaelat:
Feels great having pie on lg g6 right !, I did flashed Oreo bootloader and performed 2 flash clean for pie still don't have fingerprint I think I'm gonna try flash this another pie ROM instead of havoc and see if it's working
[T-Mobile LG G6 Guides, News, & Discussion] stoneworrior:
Everything on this Pixel experience PIE ROM is working well except stock camera and like I said the Google camera app in the play store works great. You don't get wide angle but from what I've experienced and read you get a yellow color over the entire image on wide angle for some reason. Either way I'm on pie, everything works to include gpay and Chase app after patching in Magisk so this is far superior to Oreo and all that TMobile bloat ?

[T-Mobile LG G6 Guides, News, & Discussion] chibichuba:
Yes, that is what my version was. Just follow the instructions carefully and follow notes by other users in the thread. Although I'm having difficulty getting fingerprint to work w/ 20A Oreo bootloader, not sure if it is related to using 20g.

I just received my H872, and have unlocked the bootloader & sequentially updated to 20a. I am not fully ready to go through the rooting process but am preparing. I downloaded LG UP from the provided link and cannot get it to run, neither with the phone attached in download mode nor without it connected at all via usb cable. I keep getting an error that a .dll cannot be found. However it is a completely different .dll than LGUP_common.dll found in the model folder. I am away from my main PC right now so I don't remember exactly which .dll it is asking for.

Thanks for any advice!

C:\Program Files (x86)\LG Electronics\LGUP
[T-Mobile LG G6 Guides, News, & Discussion] NoahVail:
This confused me a bit because LG UP didn't change from

"laf to another partition"

but from

"System" to "[some truncated message about backing up something]".

Nevertheless, I pulled the cable after "System" and everything else went as expected.

Final result: the procedure worked as advertised on my H872. My thanks for everyone's blood+sweat+tears.

postscript:

I don't always get a full picture right away. So, before I ever started I . . .

- read the instructions repeatedly until I had a basic grasp, from end to end

- downloaded all the files in advance and made sure I know where they went

- played w/ LG UP as far as I could

- made sure my bootloader was unlocked (it wasn't even tho phone was network unlocked)

I spent like 5 days re-re-re-reviewing everything first.

---------- Post added at 12:38 AM ---------- Previous post was at 12:26 AM ----------

I ran into this too.

I had to reverse 2 of the steps - I performed them in this order:

* Select “Format Data” and complete the format

* Choose Advanced Wipe and select the Dalvik, Data and Cache options and Wipe.
[T-Mobile LG G6 Guides, News, & Discussion] mn1968:
Thanks! That did the trick...in addition to having to reinstall vcredist_x86 for mcm100.dll. I am now prepared for the procedure. I just don't want to rush through anything.

EDIT: Took my time last night and got the phone rooted. It was actually quite easy, if not more convoluted than I'm used to doing for root. Regardless, thanks for the procedure!

Settings crash trying to enroll fingerprint on stock 20a

As I posted above, I followed the guide in the 1st post and achieved TWRP/Magisk/Root as expected, and it was actually quite painless. FWIW, I bought the phone new-in-box and manually upgraded to 20a before beginning the root process. Also...I am running stock ROM 20a. I have not uninstalled any apps, only frozen some. I have not deleted nor modified any other system file either.

The problem I am running into is trying to set up the fingerprint...it crashes as soon as I enter my pin. Facial recognition works but just not FP...it's driving me nuts! Should I flash the 20a bootloader? Would that work or bork the whole phone? The phone is basically setup as I like and I hate to do a factory reset but I will if that's what it comes to. I've attached a log from the FP crash when trying to set it up. I appreciate any help I can get with this.

Thanks!

EDIT:

Fixed my issue by updating to 20g with this. Thanks!

[T-Mobile LG G6 Guides, News, & Discussion] ankerlevel:
Is it possible to flash different ARB01 bootloaders (just the bootloader, not the whole firmware) back and forth?

For example, if I'm running 20A and I want to flash 11G and then get back to 20A or 20G.

Thanks in advance.
[T-Mobile LG G6 Guides, News, & Discussion] vampercy:
If you have done this method, and you have Twrp, you can install bootloader without any problem.

But if you haven't. Maybe you could do it But remember once you are on 11g+ you cannot downgrade to any versions prior to 11g due to anti-rollback

Now if I where you. I wouldn't do that , because if you brick your device. You won't be able to unbrick it

Flash the full kdz is better

Good luck

Alright so I'm still on 11g from like the day the LAF method went up. I'd like to update to Oreo because I've been having some issues with apps on Nougat, specifically Plex's Exoplayer v2. Does anyone else have issues with mobile playback using Plex or is that just me?

I'm on TWRP 3.2.1 with the 11g LAF, do I have to return entirely to stock and start over or can I just flash the 20g bootloader and a 20g rom and be done with it like it was for my G2 or is there a whole slew of partitions that need to be flashed and specific roms that have those need to be used?

[T-Mobile LG G6 Guides, News, & Discussion] Yeahmkd:
Not sure what 11g, 11h etc mean

It looks like Im on 10b and the phone says it is up to date. Any idea how to upgrade from here?

Nvm figured it out. Had to download lg bridge

Edit

So I ended up finding another post on here that said to partition DL 11g and select all partitions. Did it, phones not bricked, but I cant get into DL mode. Any advice?

Edit

So I got through the entire process. I have a bit of an issue now. When I ran ./step2.sh in twrp, I got a message in twrp saying encrypt data password or something. I got through the password (nothing) and restarted the phone. The phone rebooted and I got a message saying that the data was corrupt and I had to factory reset the phone. I hit the reset phone button and now I am back in the OS. I am still on 11g but I am not sure where to go from here. I also cannot make a backup in TWRP as it says decrypt took too long and killing process. Unable to mount storage. The phone has all of the Tmobile apps in it and it does not appear to be rooted anymore. Am I still rooted? Do I have to restart?

I am truly grateful for the people who develop for our devices and put up instructions like this to help us out, but I now have a brick, simply because the instructions are inadequate. They need to be much more detailed and specific.

This is from the instructions about when to pull the cable.

'.......as soon as it changes from laf to another partition, pull the USB cable'

What other partition?

Do you mean,

when it changes to system partition, pull the cable?

Isn't that a lot more specific?

When I flashed mine, it started at laf and then very quickly (too quickly to see) changed a couple of times and then went to lafbak. Is this still laf? Is it the next partition? I don't know so I decided to pull the cable and now I have an expensive, useless brick.

The same thing happened to me but I will along and have root now. You should probably keep going.

I'd look further back. There's a copy of twrp specifically for this device but not the one from twrp itself. Seems as if the one from the op will give you root but there was a system mounting issue that's fixed on this other version. So this other version needs to be installed after you do everything stated in the op.

Please correct me if I am wrong because this is where I'm coming from myself I'm not rushing but I am putting everything together I need to do this.
