I want to attempt to do this with my phone. But before I do, I want to make myself more comfortable by making sure I understand this line in your instructions.

Please let me know if I am correct or incorrect here :

In this part of the instructions, in the terminal we type "!OPEN" and not "OPEN", correct? And if I am understanding correctly the "!" is typically used as a comment in one/multiple programming and/or scripting languages, and you are warning readers not to mistake it as that in this case?

Just trying to make extra sure I don't **** anything up with my phone, hahaha. But I think I'm gonna give this a go.
[T-Mobile LG G6 Guides, News, & Discussion] MudaTrucka:
That is correct, make sure you DO put the "!" in the command

Sounds like your bootloader is locked? Did you unlock it? And did you flash the dm-verity disable zip file? Sounds like one of those issues

I'm having a hell of a time getting that fwul to boot on my windows 10 machine. I've tried multiple ways to boot into it. is it not able to boot from a micro SD card in one of those adapters or is it something else I'm missing?

its a 128gb SanDisk

I've never booted from an iso on this machine (1st Gen surface book) but have on other pcs and know the procedure. Looked it up for this machine just can't get it to run. I can see the pc try to boot into it (flicker of the logo during boot that usually doesn't happen) but it just won't run it. I grabbed the forgetful version of fwul. It was the one in iso format.

Maybe I'm just doing something stupid but if anybody has any insight it would be greatly appreciated
[T-Mobile LG G6 Guides, News, & Discussion] NighthawkXL:
Ya, I think so too. I think fastboot messed up, going to restart the process.
[T-Mobile LG G6 Guides, News, & Discussion] purplekushDGK:
Once you did that were you completed? or did you have to finish the rest of the steps?
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
Fairly sure that it was just something stupid about how I was writing the iso to the stick. I'll know later tonight when I get a chance to test it out.

Success using MAC / Parallels / Windows 10 / FWUL

Folks,

I got this all done last night and figured I post some notes to help others (especially those with MAC).

In general, USB switching between MAC / Parallels (for Windows 10) and Virtual BOX (for FWUL) can be tricky because if you have Android tools installed on the MAC, it will launch file xfer, or if you launch TWRP mount, it will mount your SD Card to the MAC, which you have to eject, and then you can re-diecrt the USB connection to the virtual box. Don't waste too much time trying to get FWUL working under Parallels...Parallels doesn't play too nice with Arch Linux. I was going to try and do this using my Mint Linux VM with Android tools, but because this was tested using the virtual box image I took that route. It worked, and VirtualBox (OS X) and the USB drivers are easy to install and use.

1) In Part 1 some asked how quick to pull the cable -- it is very quick, like once it starts flashing it will be like 3-5 seconds until in moves past step LAF, so be ready! The you wait for LGUP to timeout, your phone will be suck in download mode / unplugged, clear the error, change to the real 872 11g file, click check all, uncheck laf and let it finish and reboot. In both cases you are doing a "Partition Download".

2) Part 2 went off OK, but I could not get the phone out of download mode and thought it might be bricked. Then I figured it was still in download mode since I could run commands against it, so I re-flashed the stock 87211g and started all over again. This is a minor typo, but at the end of step two...you have:

/lglaf.py -c '!CTRL POFF'​

exit​

When really it should be

!CTRL POFF​

exit​

Since you are already running lglaf.py...

So that time when I unplugged the power it rebooted and I could get right into TWRP and continue.

Step 3 may cause some confusion if you are not familiar with adb...but basically when you mount the files in TWRP, one my system that would cause them to mount to the MAC, and I would have to eject them from the MAC and then could redirect the USB to the virtual box and run the ADB commands. Note that you may have to restart TWRP (by choosing power off and re-entering download mode to relaunch it) to mount the system partition as read / write -- but it will work.

I think that's about it -- I restored everything from Google's Backup re-arranged my desktop and I have root and the device is otherwise identical). I'll worry about installing the official TWRP later...for now everything is working...

[T-Mobile LG G6 Guides, News, & Discussion] blumpkinblake:
My phone didn't power off after unplugging it and holding volume down + power for a minute didn't work either. However, trying the !CTRL POFF did work and now my phone is perfectly rooted :)
[T-Mobile LG G6 Guides, News, & Discussion] NighthawkXL:
Fired everything up again (after having some much needed rest), all systems are functioning and root has been obtained.

[MENTION=3167089]runningnak3d[/MENTION] - Going back to restoring stock LAF, you said we can extract it from the KDZ, but where to we flash it from? or it just a image we can do inside TWRP from recovery?

The laf partition will flash first as soon as it is done and switch's to whatever comes next pull the cable. I don't remember what comes next but laf will be first as soon as it starts flashing the next partition after laf pull the cable.
[T-Mobile LG G6 Guides, News, & Discussion] xdabushrang3r:
Thanks but I need to know what comes next.

When I flashed it, first was laf, then it changes 2 or 3 times (too fast to see) and then flashes lafbak. I want to know if lafbak is still the laf partition.
[T-Mobile LG G6 Guides, News, & Discussion] vampercy:
First.. Why are you complaining?? You didn't Pay for This And you are free to do this method or not, The instructions Are ok, if you can't. Read them that's your problem, don't complain for your Mistakes..
[T-Mobile LG G6 Guides, News, & Discussion] xdabushrang3r:
It's a simple enough question for the creator of this method. I'm not complaining. All I want is specificity and clarity because the instructions in relation to the most critical point of the instructions are not OK. I still don't know if I pulled the cable too early or too late which is a big problem related directly to the inadequacy of the instructions.

1. Is lafbak still the laf partition?

2. Do you pull the cable when you see it switch to the system partition?

These points are critical and not covered by the instructions.
[T-Mobile LG G6 Guides, News, & Discussion] mn1968:
[MENTION=7279676]xdabushrang3r[/MENTION] - Could the instructions have been more clearly written? Perhaps. However, prior to using this method, I read & re-read everything, installed all required files/software and ran them up to the point before I actually did anything critical that would affect the phone, and lastly, I Googled for, and watched, a couple videos showing how this worked. I then felt prepared to do this and was successful!

I don't know the preparation you took to ensure success but knowing the warnings prior to attempting, I think that this method is not one to rush into.
[T-Mobile LG G6 Guides, News, & Discussion] stoneworrior:
It's a good thing you are having problems, or you would have bricked your phone. The instructions are straightforward to follow, and if you can't figure this out at this point, you have no business rooting this phone. You can explain advanced physics to a kindergartener all day, but the info will never sink in.

You can flash the stock rom over and over again in lgup with no ill effects and figure out what comes next by recording it. But what comes next doesn't f'ing matter for the simple reason you choose the partition download option and check laf only. That means laf is the VERY first thing that flashes what comes next is irrelevant. As soon as laf flashes and it changes to WHATEVER comes next you pull the cable. If you can't get that through your thick skull you need to forget about rooting this phone. The directions are soo freaking easy to understand a caveman can do it. If this doesn't sink in your brainpan then you need to stop and let it go you'll never understand.
[T-Mobile LG G6 Guides, News, & Discussion] xdabushrang3r:
Wow. There are some rude and very angry people on this forum. You don't need to get angry my friend. If you can't answer the questions, you don't need to comment here.

What do you mean, "What comes next is irrelevant"?? You have to pull the cable after laf or else you get a brick. It is absolutely relevant what comes next.

I have two questions that I would have thought would be simple for [MENTION=3167089]runningnak3d[/MENTION] to answer, which would help everyone with this method.

1. Is lafbak still the laf partition? Because that's what came up after laf, so I pulled the cable.

2. Do you pull the cable when you see it switch to the system partition?
[T-Mobile LG G6 Guides, News, & Discussion] stoneworrior:
Look, I apologize for the previous post. It just feels like you're attacking the OP on his directions when, to me, they seem very simple and easy to understand. That being said, I have the 872, and after the laf partition flashes, the next thing that pops up is xbl. That's when I pull the cable. If you have a different model, what comes next may be different. I can't speak to that, but again none the less whatever comes next, that's when you pull the cable. I don't know why you are focusing on what that is. You seem to be making this way harder than it needs to be. I was expressing my frustration in you not getting this, so I do apologize for that. Good luck, but you are making this way harder than it needs to be.
[T-Mobile LG G6 Guides, News, & Discussion] xdabushrang3r:
I have an H872 and I too watched the video before I did it. For me it was impossible to pull the cable after laf. I watched it very carefully. After laf, 2 or 3 flashed by so fast I couldn't read them, and next was lafbak, that's when I pulled the cable. In the OP's post, he said you have quite a bit of time to pull the cable but that was not true. That's why I'm asking for the name of the partition that is flashed after laf, because he says that's when you pull the cable, but doesn't say what the name of that partition is. In the video, the progress bar was at about 10% when the guy pulled the cable, and mine was at about 2-3%, so something is not clear in the instructions. I kind of need clarification from [MENTION=3167089]runningnak3d[/MENTION]
[T-Mobile LG G6 Guides, News, & Discussion] vampercy:
Wait..wait.. 2 3%. Really?? For me take Quiet A bite Of time To change from laf to other file. Like 30 seconds.. And the bar progress. Was about at 10%. When I pull the cable... That's Why I think you did something. Wrong. I don't know why. But something wrong Was made, but if you only get to 2 or 3% you may not be bricked. Ask other H872 users In this telegram Group

https://t.me/joinchat/ElHlskRW3-pd7_qdDRZQhw

There are many user that can help You..

That's the only way to clarify your doubts because. The dev Brian is not more here, he is in op7 forums
[T-Mobile LG G6 Guides, News, & Discussion] stoneworrior:
Maybe you should try and flash stock ROM with lgup and get the phone running again with stock firmware and make sure it isn't bricked then start over. I know it's annoying but it would be the best way at this point to make sure your phone is still working as it should.
[T-Mobile LG G6 Guides, News, & Discussion] xdabushrang3r:
Thanks vampercy. I'll try that ?

Thanks stoneworrior, but I can't turn it on at all. No power. Someone suggested changing the emmc to turn it into a H870 so I might find out how much it'll cost and try that, after I try vampercy's suggestion.

Worked almost perfectly for me, I flashed LAF without unlocking bootloader and it didn't boot into download mode. Then I just booted into fastboot and typed the bootloader unlock command and download mode started to work. So I was able to get custom recovery, root and sim unlock.

Hi I´m new here,

ma name is Paul and I succesfully rooted my G6 H872 20a with your instruction. If you read step by step it´s a very good instruction! Thank you so far!

After spending and searching for hours I´m writing to your forum because I´m not sure what to do.

I thought I bricked my G6 as I have tried to downgrade my phone. Luckily I was able to go to Download Mode and could reinstall my LG G6 with LG UP. I only used this instruction again and now my G6 is booting again. ( I had a boot loop because I deleted all folders and flashed in TWRP not as I should ... )

I have to downgrade because I have Android 8 (Oreo). The problem is I have a network lock and I know they are services to unlock the network lock but it´s only possible with Android 7.

What files are needed and what steps I have to do to downgrade? I need someone who can tell me step by step because I think next time I won´t have luck and my phone will be bricked. I found a lot of instructions but there are aspects I don´t understand.

So I have:

- TWRP

- H872 20a image installed

- bootloader is unlocked

- rooted

Shall I flash with LG UP or TWRP and which image I have to use?

My idea is to download Link to 11g KDZ and use the instruction from runningnak3d (first post). Is it possible to do downgrade on this way?
[T-Mobile LG G6 Guides, News, & Discussion] Tung Trab:
This instruction worked for me on 20g, don't need to downgrade to 11g. Thank you so much :D

[T-Mobile LG G6 Guides, News, & Discussion] an0ym0us:
Thank you so much. I got orangefox flashed and running and it's much nicer then TWRP. Now that I do, are there any custom ROMs? Or am I stuck on stock and forced to debloat? And if so, is there a safe to remove bloatware list? Btw how did you get your Win 10 to look like that.
[T-Mobile LG G6 Guides, News, & Discussion] immns:
It's okay. i did many times flashing twrp on 20g.

I'm using havocOS, you can find many custom ROMs on "generic" LG G6 forum some of them has specific variant for H872. I'm using FWUL on vmware to perform twrp flashing (because I don't have any USB stick lying around and I don't wanna mess with windows bootloader).

If you decide to make it stock, then perform refurbish option using LGUP with current KDZ. It will reset everything and make your phone fully stock.
[T-Mobile LG G6 Guides, News, & Discussion] vampyro:
lgup refurbished option not allowed .. it said it doesnt support refurbished..

At times the instructions include special steps for "20a", and at times it refers to Oreo.

What KDZ did you download when the OP has nothing for 20g - the latest is 20a.

Thanks.

---------- Post added at 09:18 AM ---------- Previous post was at 09:14 AM ----------

So, you are saying that you are 100% sure that using the latest 20a KDZ in the OP will work fine with phones that are on 20g?

You seem pretty confident but just wanted to make sure before I turn my phone into a papwerweight.

Is there any reason there's no 20g KDZ if the guide says it supports upto 20g?
[T-Mobile LG G6 Guides, News, & Discussion] immns:
OP said before he/she dont use lg phone anymore, so 20g confirmed by another user. another reason maybe OP won't bother to write another sentence when it can be stated on tittle or OP forgot to write that. to be clear, I'm using 20g kdz (this part you can chose whatever you want from 11g to 20g kdz) alongside H918 10p KDZ for laf (this part is where this exploit worked). as long as you pay attention to PROCEDURE PART 1: Getting a working LAF onto your phone you'll be fine, I'd like to call it "critical path." :fingers-crossed:
[T-Mobile LG G6 Guides, News, & Discussion] Tung Trab:
Maybe he has moved to another device and don't have time to update the link for 20g. You can download the 20g KDZ from here : https://lg-firmwares.com/. There's no way to use 20a KDZ if you're on 20g.

I'm REALLY stuck

I took my time and followed the instructions to the T.

Successfully flashed the LAF using the patched LG UP file and process.

Used FWUL to install TWRP per the instructions and also did ./step2.sh to root the phone and supposedly install magisk which an early post with a similar problem should have been a solution, however the phone did NOT boot into the OS as it was apparently supposed to.

Now I have TWRP encryption asking for a password that was not provided and without the password the phone literally wipes itself and reboots to stock Android with no root!

I would really appreciate some help if I missed something or if there's a workaround because right now I just have a stock phone with a TWRP recovery I can't use and a super annoying message before the LG boot logo telling me that my "system cannot be checked for corruption".

Any help appreciated.

Download mode lost :'(

Can somebody help? My phone didn't brick but can't use download mode anymore.

I was using 20a official stock firmware and follow this guide step-by-step carefully, after doing Laf part, firmware flash back and boot successfully, but download mode seem to not responding for FWUL and even can't hard shut down the phone, only after battery burned out and charged I can boot to OS normally, once boot to download mode and the phone seem to be dead.

In download mode, Windows does not recognize what device it is, FWUL even not detected it, I realized this after I'm doing './step1.sh' part but did not worked, I re-run the script many times in different USB port or try to doing it in Virtual Box and got same result, so I tried to shut down the phone, but the phone not responding at all (after clicking power and volume button couple of times, LCD somehow turn to brighter, but still not responding), so I force to wait it burn out the battery then I can reboot the phone.

I was trying to get rid of T-mobile network lock.

Edit: when checking it in adb, it says its offline and in FWUL it just shows but isn't recognized

Someone has had a similar issue. Someone reccomended to go back to stock, and then do adb reboot bootloader and fastboot oem unlock. How exactly would I go back to stock?

Edit 2: Someone has told me that my problem is unfixable. About the "fastboot oem unlock" you do "adb reboot bootloader" THEN "fastboot oem unlock" I, a noob didn't realize that
