Yep. I really really regret coming across this thread. I definitely have fastboot. As I said in my earlier post all my mobile hacks have been with Samsung & nexus/pixel so this LG and qfil was just way counter intuitive at first. There wasn't even a flash button on the software u just close a window and it flashes... That on top of poorly worded instructions equals a lot of bricked phones I imagine. It sucks cause I loved that dual screen and I thought if I could get the BL unlocked and a rooted rom flashed this would have been my favorite phone ever. I used the restore files someone gave me and now it won't even come out of EDL. I'm so frustrated and discouraged ready to give up and maybe come back to it later hopefully someone has the files to restore all the ones this method bricked for att android 10 users... The one shared with me didn't have abl_b but I tried it anyways now it's really ****ed up I think
[LG G8 Guides, News, & Discussion] AsItLies:
I sympathize with you, it's more complicated than other devices.

But, and this doesn't help you now, but maybe in the future; The very First THing You Do With a NEW PHone is BACK IT UP!!

That's a very common thing at the beginning of virtually all guides like this one. And!! If you don't know how to do that... ASK!!

So this is where you are, you didn't back up your at&t device, which unfortunately they don't make the kdz available (all the more reason to back it up), and you've gotten a back up from someone else that may or may not have been the right one / version for your device.

whoa is me, for sure.

I'd suggest to look for a bkerler backup of your device. The bkerler python edl tools do a complete backup, so there are some partitions you DON'T want to flash, as they contain imei and s/n. So those, if they are in a backup you find, have to be taken out.

Short of that, get a kdz of a different variant, use kdz extractor to get the gpt tables and the few partitions needed to get lgup to work, then follow the crossflash guide to at least get the device working again.

One last note, the people that write these guides are regular users just like you and me. They are not paid professional technical writers that work for major corporations. Have you ever tried to write a complicated guide for something like this? I guarantee you there will be people that will tell you it's not clear, no matters what you write. And if you write the guide in a way that explains every last tiny detail, others will tell you it's too 'wordy' and way too long, and they didn't read it.

good luck.
[LG G8 Guides, News, & Discussion] Knoa6:
Thanks man. I'm sorry if I seemed a bastard, I was quite frustrated. I've just never ran into an issue like this that I couldn't fix and it had me pulling my hair out. After letting myself chill out a few days I'm keen on trying your suggestions.. what is the bkerler backup? Not familiar with this but I will do a Google search and thank you for your help. Also if anyone has the files I need please PM me and I'll tip you for the trouble. Happy new year
[LG G8 Guides, News, & Discussion] Knoa6:
Ok well after a few more hours of tracking down files...

I learned the phone died while I was trying to cool off from this and now I can't get it back in EDL or to charge or come on at all.

I've heard little comments here and there regarding a way to short 2 pins together after removing the back that will restore a factory state in the device.

Can anyone please point me to a tek for this LG reset?
[LG G8 Guides, News, & Discussion] sinkoo1979:
Flashed back to stock. Flashed abl, xbl, xbl_config, laf and I had access to download mode. Back on stock. Thanks for your reply
[LG G8 Guides, News, & Discussion] Shaglo:
*Edited*

As I understand if you got twrp installed, the hard reset key combination (vol- and power button) does not reset your phone instead it leads you twrp. if your phone resets you twrp is not installed.
[LG G8 Guides, News, & Discussion] robnitro:
Why did you go back to stock? I have a sprint g8x and there's no kdz for them.

So, I'm just wondering how I could go back if theres a problem, without access to kdz.
[LG G8 Guides, News, & Discussion] cloud1250000:
You back up your partition using qfil. Don't mess up the rename part :) (as described in this guide)

Good luck:)

And yes.. the abl_a you download here is meant to be flashed over both abl_a and abl_b (you need to have made a backup of these before doing that.. as described in this guide)

Have fun :)
[LG G8 Guides, News, & Discussion] Shaglo:
Although I got the bootloader unlocked Im still unable to install Magisk properly without it going into bootloop on lockscreen. Even if I install twrp, it will causes encryption(asking for non-existent password). Applying force decryption method will lead into decryption unsuccessful on startup with no fixes. If you have similar model Korean V50, be wary of this problems. Backup everything stated by OP. If this occurs to you, just apply backed up original boot_X.bin using qfil.
[LG G8 Guides, News, & Discussion] Shaglo:
Finally I got it working. My problem was after installing Magisk with OP method, I have bootloop on security lockscreen. i cant say for sure which part fixed this but my guess is DONT USE SECURE STARTUP. If you have that, remove it before proceeding to Magisk installation.
[LG G8 Guides, News, & Discussion] sinkoo1979:
thanks for the guide and helping me yesterday to reflash stock when I was without download mode.
[LG G8 Guides, News, & Discussion] ldeveraux:
Will this work on the LM-V450VM (Verizon V50 model) or the LM-V450PM (Sprint V50 model) ? Looking to upgrade from my V30 on Verizon
[LG G8 Guides, News, & Discussion] mc_365:
What exactly does this last step do?

The reason I ask is, after I Unlocked and Rooted, I flashed TWRP through magisk.

Then Magisk manager would show N/A for root. So before rebooted, I reflash the boot_b.bin (in my case) and seems like my TWRP was fine but I still had an N/A on either Install or Status, I forge so I did the last step quoted above and then everything in Magisk looked good but TWRP was gone.

I've never flashed a recovery that way but It's been a while since my HTC M8 days, I've been on samsungs and the v50 is just now getting Unlocked.
[LG G8 Guides, News, & Discussion] SkivelBrun0:
I do this on mi V50 and it works well...

But to get the root i can´t.

I try with abl_a and b restored to the backuped

and boot_a restored to the original backuped, and boot_b with the magisk patched file, i got root but no sound.

And with abl a and b original backuped

boot_a with the magisk patchetd file and boot b with the original backuped and not working.

HELP!!!!!!!!
[LG G8 Guides, News, & Discussion] SkivelBrun0:
How do you get the root working? i try patching the boot_b only and i have root but not sound, so after restart the phone gets bricked.

So i patched the backuped boot_b to get working but no rooted
[LG G8 Guides, News, & Discussion] cloud1250000:
You need to flash TWRP with magisk (this removes root), then turn off and boot TWRP using combo key.. proceed with the format of data (because encrypted), flash magisk and then flash dm-verity disabler (it removes the encryption). Done :)
[LG G8 Guides, News, & Discussion] bigloco:
I would like to know if this method has been confirmed working on the Verizon V50 5g model variant.
[LG G8 Guides, News, & Discussion] Snowfairy:
Thanks, my boyfriend do this to my phone and everything went ok, but now my phone tells me that it have a system update, can i update my phone? in software version it says V450P20a
[LG G8 Guides, News, & Discussion] mc_365:
Can't mount anything in TWRP so wipe fails
[LG G8 Guides, News, & Discussion] mangojain:
I was trying this and got to the part where i backed up abl_a, abl_b, boot_a and boot_b ,then replaced the abls with the supplied abl. However, my phone is neither booting up normally nor into fastboot after that. I have tried restoring the backed up abl files, but the problem persists. I can only go into edl mode. Can you guide me on restoring the phone back to how it was please.
[LG G8 Guides, News, & Discussion] rjohnson2:
once this is complete will i be able to bypass the verizon hotspot provision?
[LG G8 Guides, News, & Discussion] mc_365:
No. This process may give you the flexibility to change other thing that will accomplish that goal. But there is nothing here to address that specifically.
[LG G8 Guides, News, & Discussion] AntonioxD90:
Después de hacer todo este proceso, puedo actualizar a Android 10?

Mi teléfono es LG G8 AT&T que está en Android 9

pero quiero saber si el kdz de Android 10 a install es el de Sprint? O cómo lo puedo actualizar a Android 10 después de este proceso. Gracias de antemano :))
[LG G8 Guides, News, & Discussion] rjohnson2:
Thanks, do you know if there is any way of accomplishing that once we have unlock and root?
[LG G8 Guides, News, & Discussion] Ricky Almonte:
to relock the bootloader would it be the same as this guide?
[LG G8 Guides, News, & Discussion] AsItLies:
there's a very important aspect to relocking a bootloader, and that is the device has to be completely stock. It's best to use lgup and flash the kdz if possible. Essentially, if you've had root, and made any changes that are still there, trying to re-lock could semi brick the device.

completely stock, then use engineering abl to 'fastboot oem lock', then use fastboot to flash original abl back. done.
[LG G8 Guides, News, & Discussion] vdbhb59:
Any idea if it works on Wing-5G (LMF100)?
[LG G8 Guides, News, & Discussion] Ricky Almonte:
Thanks for the information, but since I have the sprint variant and we don't have kdz available I risked a lock, but everything is fine, I already have the bootloader lock

thanks!
[LG G8 Guides, News, & Discussion] AtrixHDMan:
Will this work with a Verizon LG G8 on Android 11?
[LG G8 Guides, News, & Discussion] AsItLies:
No reason why it shouldn't. The only thing with Verizon is you have to flash the provided frp partition because they grey out the allow OEM unlock in dev settings.
[LG G8 Guides, News, & Discussion] AtrixHDMan:
I haven't tried it yet.but I thought all Verizon phones had greyed out OEM lock and the bootloader cannot be unlocked.

I really don't need Android 11 on my Verizon LG G8,but was hoping Volte was added to Android 11 as I use AT&T for service.No Voice of LTE.Do you know the answer to that I'd I update.
[LG G8 Guides, News, & Discussion] AsItLies:
Well for someone to answer that they'd need a verizon phone, have put a11 on it, and use at&t service. That's not me.

the thing with volte working is 1) phone has to be capable of it (the G8 is) 2) the rom has to have it 3) the carrier has to allow it 4) the plan you have has to be provisioned for it.

it's not just as simple as 'the phone / rom has it' then it works. It's more involved. As a matter of fact, I know at&t used to, not sure if they still do, but they didn't allow using volte on their network unless the phone was an oem at&t phone (they check imei to verify), and yer using an at&t rom.
[LG G8 Guides, News, & Discussion] AtrixHDMan:
Well according to a list of phones the Verizon variant is listed as one of the phones that will work after the 3g shutdown in February 2022.So it must be capable of it,but my phone when I make a phone call it falls back to 3g.

This doesn't happen on my Pixel 3 and there's a switch for Volte unlike the Verizon LG G8 thinq.
[LG G8 Guides, News, & Discussion] Ebizza:
Thanks. I now have an unlocked BL and root.

I can no longer boot into fastboot (trying to install TWRP). I've tried all button combinations (same combos I used when unlocking my BL).

It seems i no longer have fastboot. What do I do?
[LG G8 Guides, News, & Discussion] AsItLies:
You get fastboot when you flash the engineering abl to the abl partition. You did that to unlock the bootloader right? After unlocking it, you're suppose to flash the original abl back, so that the device will boot normally. You did that right?

Well, if you did the above, as you should, then u no longer have fastboot available.

So really it's almost impossible to answer your question, without more details. Why do you think u should be able to get to fastboot if the engineering abl is no longer there?

afraid there's obviously some details you're leaving out that one can only guess at.
[LG G8 Guides, News, & Discussion] Ebizza:
I didn't know unlocking my BL made me lose fastboot. Would I get fastboot if I replace the original abl with engineering?
[LG G8 Guides, News, & Discussion] AsItLies:
How did u unlock the bootloader? As said, the normal way is to use the engineering abl, which u flash with qfil. Then u unlock the bootloader and flash the original abl back.

Is that what you did? If so, it should be obvious that the eng abl gave you fastboot, and when you flashed the original abl back, then it was gone.

why is this confusing?
[LG G8 Guides, News, & Discussion] EdersonFA:
Hello guys, I am new to this forum. I saw this thread and I was interested in getting a rooted anroid phone so I went out and purchased a LG G8 ThinQ. A close friend of my is and IT tech and he was attempting to follow this guide with me and get my phone rooted. Unfortunatley all has gone well untill I try to go into EDL mode. Everything I try it just boots up normally. My friend has even tried to go into EDL mode using the commands but nothing works. Please HELP!!!

Ok guys so I somehow managed to get into EDL mode but now for some odd reason I am unable to go into Fastboot mode. Whenever I do the key combos, it just says that my phone is 100% charged. How can I put go into fastboot mode? Someone please help
[LG G8 Guides, News, & Discussion] fend0rski:
noob here, hope someone can help...

i got a verizon v50 from ebay(V450VM20d).

used this guide without an issue to unlock bootloader (did not root). backed up a few more partitions.

put a verizon sim in it, the phone activated fine, and downloaded some apps, i made a call and checked that LTE stayed on and i could access internet(VoLTE).

i wanted to downgrade to Android 9.

installed LGUP 1.16.0.3(common dll 1.0.40.2), flashed V450VM10j_01_VZW_US_OP_0305.kdz as an upgrade - stuck in "security boot up"(or some such) - asking for passcode and can't get through.

flashed the same kdz as "refurbish" - successful flash - no network.

tried a couple of different combinations with different common dll and different kdz/refurbish - successful flash - no network.

tried LGUP 1.17.0.1 (supposedly LGUP Common DLL Ver 2.1. included) - flashed V450VM10j_01_VZW_US_OP_0305.kdz from cmd - successful flash - no network.

i have tried flashing with and without the sim in the phone and the phone would simply not aquire network signal, after multiple reboots. VZW does show up in APN (if i understand this correctly), but it doesn't help.

the sim does work in different phone.

any help/advice is much appreciated.

edit: connected to wifi, checked for updates, successfully installed update. still no service :(
[LG G8 Guides, News, & Discussion] EdersonFA:
I know I sound like everyone else who attempted to follow this guide and accidentally did not follow it exactly the way it was intended to, but, after a lot of trial and error I was able to root my LG G8 as well as successfully installing Magisk. A gentleman by the name of @BeAsT helped out a lot in the XDA discord and he also referred me to a LG telegram group where someone else by the name of @Ebizza was able to help me figure out the rest.

I would like to confirm that if you guys take the time to follow this guide and you have all the necessary prerequisites, it 100% works.

Thank you guys so much for making this thread/guide it helped me out so much.

[LG G8 Guides, News, & Discussion] tankcircuit:
So I was giving this a go to try and root my LG G8 from sprint since i had it hanging out collecting dust.

after following the instructions above, I had lost all touch screen capabilities. after the step in QFil right before you go into the adb interface. have i may written over the wrong file? what have i done, and is this this a full paper weight now?
[LG G8 Guides, News, & Discussion] Ebizza:
You flashes the engineering abl on qfil. That's why you lost touch. Restore the backed up abl and you'll regain touch
[LG G8 Guides, News, & Discussion] tankcircuit:
i can not restore back now, its tells me that device is locked, and go to a link for a red case.

I just need the right factory files i believe, but have been looking for them everywhere
[LG G8 Guides, News, & Discussion] AsItLies:
Sprint does not make their kdz public. You'll never find it. Hate to say it but this is where you should have been sure to follow the directions when they said 'Back Up Everything'.

maybe someone has a sprint partition backup they can help you with, which partitions do u need?
[LG G8 Guides, News, & Discussion] tankcircuit:
YES this is where i do realize i messed up, and as for what partition i need, um i think im taking i would need the sprint factory recovery img. or to at least the factory abl file to get touch back
[LG G8 Guides, News, & Discussion] AsItLies:
try this abl_a it's sprint 10, might work for you.

Please tell me how did you go about it (unlock bootloader) because i've a verizon v450vm device and I'm planning to unlock the bootloader but since there's no OEM unlock in the developer option.
[LG G8 Guides, News, & Discussion] fend0rski:
I am not right person to ask - I really have no idea what I am doing, I just followed the guide and had no problems at all. The guide says the oem unlock is for all variants, other than verizon, so I didn't do that.

I did read through the whole thread 3 times though, before I started...
[LG G8 Guides, News, & Discussion] AsItLies:
follow the guide. The guide tells you specifically, for verizon phones you have to flash a special frp image to get around the no oem unlock option.

read the guide.

Hello everyone, I have an LG G8 thinq from xfinity mobile that I would like to open band since it asks me for code without network, but I wanted to open the bootloader first and I would like to know if this method is compatible with my LG since I do all the steps but when I enter the partition manager, I get an error from qfil "download failed: Sahara failed: QSaharaserver failed: process failed"
[LG G8 Guides, News, & Discussion] AsItLies:
Sahara error is very common. Numerous possible solutions: 1) use a usb 2.0 port (not3.0). 2) be sure to use a usb data capable cable, not a charging cable. 3) with windows you sometimes have to disable 'signature verification'

Is this possible for an LG G8 from Sprint? I'm on latest firmware (Android 10 G820U21f) and wondering if they somehow patched something up? Don't want custom ROMs (yet) just want to root the stock android (or maybe even install the stock version of Android 11 from other G8 carriers)
[LG G8 Guides, News, & Discussion] AsItLies:
Yes it's possible, and yes you can xflash to other stock variants. Unfortunately the only 2 that have a11 are Korean Open and Vzw US. The korean model has 3 cameras in back so it's stock camera app doesn't work on other variants, and you can't install the other variant stock camera app. The vzw rom has potential, still looking at it's possibilities.

It's uncertain if any additional carrier roms with a11 will appear.

Oh, we are very likely to see A11 for att and tmo towards end Jan.

[LG G8 Guides, News, & Discussion] AsItLies:
So did you flash the engineering abl to a and b? Did you use the keys needed to get to fastboot from qfil?

There's more to it than just backing up the abls.

i think i didnt flash engineering abl to a and b,i only backed up,probably, but i used keys to get into fastboot but nah,didnt work

The stock abl's don't have fastboot. No matters what keys you use, with the stock abl, you'll never get to fastboot.
