May I ask any solution to unBrick?

I followed the instructions but I did not unlock the bootloader. Now the download mode is not available and the system is down, too. Is there any solution to unBrick it :( ? Many thanks!

I'm on 20g already, no luck i guess.
[T-Mobile LG G6 Guides, News, & Discussion] vampercy:
Downgrade and then do the process
[T-Mobile LG G6 Guides, News, & Discussion] RashaMatt:
I followed the rooting process on 20g and it worked fine for me.
[T-Mobile LG G6 Guides, News, & Discussion] hopsNbarley91:
I'm sure these questions were answered but I've seen them asked repeatedly. Hopefully they help.

1. If you have 20g just download the 20g kdz from Lg-firmwares (Google it)

Go to the menu, OS, Oreo, h872bk, and download the one for 20g. It worked for me.

2. Pull the cable when flashing laf as soon as it shows xbl. It took a short amount of time for me.

3. When installing TWRP in fwul it kept saying it failed and trying 5 times blah blah blah ( can't remember exactly what it said.) But it ended up working even though it said it failed. Strange.

Hopefully that helps whoever needs it.
[T-Mobile LG G6 Guides, News, & Discussion] Dlions:
Thanks

I would like to return to stock to test some things out how do i do it with 20g?

God Bless
[T-Mobile LG G6 Guides, News, & Discussion] RashaMatt:
AFAIK you can treat 20g exactly the same as 20a. Just follow the instructions in this topic for reverting to stock, but use the 20g kdz instead of 20a.

I am on H872 10q should I update using lg bridge before attempting this guide? Much thanks
[T-Mobile LG G6 Guides, News, & Discussion] Tung Trab:
The OP stated clearly that you need to be on 11g or above. So you had better upgrade first. Remember that you can only upgrade to 20g or below
[T-Mobile LG G6 Guides, News, & Discussion] benphillipstn:
I've never used lg bridge. Will it let me choose the 20g update?

or can I update from 10q using a 20g kdz?
[T-Mobile LG G6 Guides, News, & Discussion] Tung Trab:
Use lg up, not lg bridge. You can download the 20g or 20a from the OP then use lg up.

Which one should I choose for 20g
[T-Mobile LG G6 Guides, News, & Discussion] Danfinelli:
I believe if you're a stuck in some type of problem you're gonna have a problem getting lg up to work because it won't recognize the phone correctly. Download lg bridge and try the error recovery thing that usually works quite well. Of course it will mean you'll have to start the whole process again if you want root.

*Side note - if you decide to use lg bridge to "rebirth" your device it's going to boot up eventually with the bootloader unlocked in the interface but not in fastboot. You need to go into dev mode and lock the bootloader up as well as in fastboot and restart the phone with it locked in order to truly start the process again. Not responsible for ****. Lmk how it goes

H87220g (20g)

Thanks! I succesfully flashed Magisk, recovery and custom ROM using this method! I had problems with flashing TWRP via ADB CMD [ERR: FAILED (remote: unknown command)] so luckily I found this method..

For anyone wondering, yes, you can use this method for H87220g (20g) model.. You just use/download 20g kdz file, there it is: 20g KDZ.. Then just carefully follow the steps given as for 20a - use SD Card to flash TWRP 3.2.3 (use the one that is given in the steps), and then you can flash other things you want.. :)

WARNING: For this "substep":

• After the flash is initiated, pay close attention to the "step" and as soon as it changes from laf to another partition, PULL THE USB CABLE!

At least in my case, the "step" changed from laf to another partition in like 1-2 seconds max, so yeah, I had only 1-2 seconds after i started flashing process to PULL THE USB CABLE..

Hopefully this is gonna help some of you out there who are not sure about this method.. It may seem complicated and risky but when you carefully follow the steps and do it step by step without skiping any, it's really simple.

Everything was ging fine until step #2. Fire up the put it in d/l mode, fire up FUQWU linux or whatever and run the script.

Even tried the power button alone for 3 minutes. Wont turn off. Stuck in this stat unil it dies I guess. Phone isn't recognized LGUP. Oh well hope it dies fast!

Let the battery die and restarted. Got it working! Thanks for the hard work!

Root
[T-Mobile LG G6 Guides, News, & Discussion] Uchina:
Root worked perfectly!...first time around.

Can anyone point out what I'm missing here?

Backstory

Recently I messed around in twrp trying to fix BT mac address issue, and must've screwed something up.

Gets stuck on LOS, Havoc, PE boot animation no matter if I wiped/formatted and reinstalled img in twrp.

I stumbled across a fix for this in one of the forum but with verry little detail to go off. So here's what I did.

twrp-> install -> install img -> and I flashed all the options (laf/modem/bootloader/etc...) with this zip file "h87220e_StockLAF.zip".

After reboot, I was able to get the stock "Firmware Update" with "volume up" and flashed "H87220g_00_1228.kdz" using "LGUPv20dll".

Phone boots to stock img but the problem I'm having is, when I try to root this time there are few differences compared to first time around.

1. After finishing up the "Select all partitions except laf" part of the guide, phone reboots to 20g stock OS. So I reboot my phone and load "Download Mode" which eventually loads to "Firmware Update"

* Seems to me this is the root of this whole problem. Somehow LGUP can't or don't have write permission to flash the .laf partition.

2. I ignore the fact that it's supposed to be in "Download Mode" not "Firmware Update" and boot to "fwul".

3. I run the "runningnak3d" script with my phone still in "Firmware Update".

* BTW here is what's on the "Firmware Update" screen.

- Do not unplug the USB connection until the process is complete.

- Progress bar. 0%.

- 633E B83

- Official / E / L / RO

4. and finally here's the log after executing "./step1.sh"

Screen shot of ./step1.sh log.

(Noticed hash doesn't match)

LGUP

Checked only LAF and unplugged right after laf.

( I noticed that "laf" is part of the changed partition(s). I don't think I saw that the first time around but I could be wrong.)

Checked all except LAF

( Should there be pop up for "Partition(s) Changed" "laf" "lafbak"?)

Currently phone is running in 20g kdz and works flawlessly. I just want my twrp back. Please help!
[T-Mobile LG G6 Guides, News, & Discussion] Uchina:
Solved.

___________________________________

Figured it out... I'm an idiot.

(Choose partition DL again, and this time pick the H872 KDZ for the version your phone was on prior to flashing 10p (11g, 11h, or 20a))

- This part is apparently very important :D

I downgraded to H87211g and flashed laf using H91810p_00_0717.kdz and everything works like it should.

Also the reason all this happened to begin with was because my Bluetooth's mac address was missing but now it's all fixed after completely reloading twrp :good:

___________________________________
[T-Mobile LG G6 Guides, News, & Discussion] tejtank:
I'm in the same boat - had 20g and now want to restore download mode but linked file no longer available.

I did find 20e Stock LAF from - https://xdaforums.com/tmobile-g6/development/stock-t-mobile-g6-stock-collection-t3875515

And from what I understand, we boot into Recovery TWRP and flash it on LAF.

However, I'm not sure if I need 20g LAF or can flash any 20X LAF.

Hoping someone will confirm before trying anything.

Based on above post #1057 by [MENTION=10981687]Uchina[/MENTION], looks like he used 20e LAF to get download mode back.
[T-Mobile LG G6 Guides, News, & Discussion] Uchina:
_____________________________________________

I'm not 100% sure what you're asking.

I flashed "h87220e_StockLAF.zip" via twrp.

TWRP -> Install -> h87220e_StockLAF.zip -> Swipe to flash.

Shouldn't matter which "20x" since I've done this on "11g" "20a" "20e" "20g" during my troubleshooting.

Again I don't fully understand your question but flashing "h87220e_StockLAF.zip" will put stock "Firmware Update" mode back on, and from there you can flash stock KDZ via "LGUPv20dll".

Let me know if that helped or anything else I can help you with.

Here's an example of what you'll get after flashing "h87220e_StockLAF.zip".

(Ignore the progress bar % and what's on the text box below. You might see different info)
[T-Mobile LG G6 Guides, News, & Discussion] tejtank:
Thanks for the reply.

That's the download mode.

I wanted to enable download mode and was not sure which laf to flash.

Thanks for confirming that "h87220e_StockLAF.zip" or any 20x laf can be flash to get download mode (firmware update) back.

Did you had to select 'laf/download" in TWRP or just flash it?
[T-Mobile LG G6 Guides, News, & Discussion] Uchina:
You can actually just flash it.

Hello

"If you are rooting on 20a, you will need a Micro-SD card. Copy the TWRP 3.2.3 image and the latest Magisk zip to the SD card."

Is this part also necessary on 20g? Thanks
[T-Mobile LG G6 Guides, News, & Discussion] ernobe:
I think the procedure applies for all variants of h872 (20a and 20g included). Anyway, it's what I did on my 20g. In my case everything seems to have worked and I'm rooted. The only issue I can think of is when I did a wipe of dalvik, cache, and data and got a couple of red lines saying something like "unable to decrypt dalvik". Then when I went to restore download mode and flashed the laf partition, besides the "reboot" button the other one said "wipe dalvik and cache". Are they still encrypted? Though like I said, Magisk seems to be working fine. Anyway, a huge thanks to everyone who made it happen.

If I don't do that I am stuck in the download mode (little rectangle). help please
[T-Mobile LG G6 Guides, News, & Discussion] n.j.stein:
I just ran into this issue today as well. This might be due to a GitHub -> GitLab migration after the Microsoft acquisition. Anyway, here's how to get around it:

In FWUL make sure you have a network connection then:

1. Open a blank terminal. Don't go through the LG icon on the desktop, just open Terminal Emulator.

2. Execute the below commands:

git clone https://gitlab.com/runningnak3d/lglaf.git
cd lglaf

3. From here on you can resume following the guide.

git checkout h872-miscwrte
./step1.sh

After the script runs, unplug and go back into download mode. It will take a few seconds, but TWRP will eventually boot.

Part of this procedure is replacing LAF partition, that's why you've lost download mode. Restore it and you'll get it back.

I also recommend followint this step by step to unlock/root/flash new recovery: https://xdaforums.com/t/root-flash-...for-lg-g6-h872-20g-original-firmware.4201125/

When you reflash the 872 11g KDZ with LGUP are you updating everything or just laf or other stuff? I think you need to update everything to reset it.

Also that last step you showed doesn't actually do anything -- it just lists the partitions...did you do the step afterwards where in your case, same as mine, you substitute 39 for 44 from the OP?
