i did reinstall this new error is coming
[LG G8 Guides, News, & Discussion] netmsm:
Reset the phone.

Open qfil and prepare the settings.

Now, reboot the phone into EDL.

Go to partition manager as qfil detects the port immediately.

extracting dz or kdz file where is lun 6 how to flash it is it through bin or image file ?
[LG G8 Guides, News, & Discussion] netmsm:
Press and hold vol_ and power for 10 seconds.

LUN6 and LUN3 are both hidden.

Have you tried diffetent KDZs? and on different KDZs do you get the same error?

Use KDZTools to extract LG new KDZs. It uses Python libraries.

There's another version that uses Windows libraries (attached file).

Read the help file and see examples to learn how to use them.

i get it i have to go in parition load respective lun file bin i should flash all of them will it solve problem?
[LG G8 Guides, News, & Discussion] netmsm:
Actually this case is weird!

I don't think so.

You may try another way of flashing.

First way is to use another app such as LG Flash Tool. It needs some preparations which you can find and learn on the web and also needs to erase the necessary partitions.

The second way is to go through restoring partitions which I completely explained here.

Before doing anything, make sure you have created backup of modemst1, modemst2, fsg and ftm.
[LG G8 Guides, News, & Discussion] Chaitanya More:
I give up on this device it seem there is no way to solved this new error about lun 6 rather than trying n trying different method i did flash every partition it still cant boot there was sudden change saying in security check up message it will boot. later i did flash all of them but it revert back to sprint lol
[LG G8 Guides, News, & Discussion] Andy2004:
Howdy really grateful for this tutorial as I wasn't able to update my device for some reason. My question now that I flashed Android 11 am I able to downgrade to Android 10 to unlock the bootloader? If so do I just follow the steps again. Thanks again in advanced.
[LG G8 Guides, News, & Discussion] syneoa:
Has anyone successfully flashed Sprint V50 to A11 using this guide and kept bootloader locked?

From information gathered from this guide, there is a need for another modem to get signal/data, thanks to @cloud1250000. Also, getting opid mismatch error is almost given since OP is not modified and intention is to keep this clean with booloader still locked to avoid problems with many apps detecting tampered device and refusing to work.

More info is needed but this is all I got from this thread in regards to Sprint V50 and locked bootloader.

UPDATES:

Thanks to @abg360 who have successfully flashed his Sprint V50 to A11 there is more info about it:

Bootloader stays locked.

Key attestation is lost, if you're using NFC for payments, this may not work anymore.

LG mobile switch will not work.

Safety net passed.

Widevine L1 lost, phone is on L3 after flashing.

FTM partition have to be hexedited, erasing serial number and putting correct NT code to avoid signal lost.

If flashed with EU A11, there is new hidden menu with field test in which you can setup VoLTE and hopefully make it work.

There's no OPID mismatched error.

System is running smoothly barring the issues described here.

As we can see, situation is not ideal for Sprint V50 users wanting to crossflash to A11, I will update this post with new info when available.
[LG G8 Guides, News, & Discussion] bigd2337:
I can confirm that this worked for me on an AT&T LG G820UM on Android 9 was able to flash it with Android 10 G820QM20c_00_NAO_US_OP_0809.kdz Thanks !!!
[LG G8 Guides, News, & Discussion] netmsm:
Yes, do it again on an a10 kdz.
[LG G8 Guides, News, & Discussion] AsItLies:
Also Andy, If I'm not mistaken (a11 is very new for G8), there's no reason to downgrade just to unlock the bootloader. You should be able to do that on a11.

cheers
[LG G8 Guides, News, & Discussion] abg360:
I flashed and it is locked.

The modem is from the cross flash v500em guide but you have to edit by hex editor your ftm, to make it work you have to erase your serial number and put the correct nt code to avoid no signal no errors. You lost key attestation so there is no way to use LG mobile switch but safety net pass. I don't know if widevine L1 changes for the A11 update or for the cross flash but now is L3.
[LG G8 Guides, News, & Discussion] bigd2337:
This guide worked for me on an AT&T LG G8 ThinQ cross flashed to NAO_US android 10. the only thing is my serial number is missing now will that affect anything?
[LG G8 Guides, News, & Discussion] AsItLies:
No, that isn't a big issue functionality wise. But you most likely can get it back by using qfil and flashing your original ftm partition back.
[LG G8 Guides, News, & Discussion] bigd2337:
Oh ok thanks!
[LG G8 Guides, News, & Discussion] syneoa:
Thank you very much for a very valuable and technical info about it! I have updated my original post to reflect on your findings.

When/if you can, please tell us more about functioning of any apps that checks device security, like bank apps, or crypto wallets or some authenticators, are they working? Also about op id mismatch error, is it present and how in general you are satisfied with your crossflashed Sprint V50?
[LG G8 Guides, News, & Discussion] netmsm:
Restore the original FTM.

Does anyone know if everything will work just fine if I were to cross flash the A11 Korean update to my US version LG G8? They still haven’t released the US A11 as far as I can find. Would this work or will there be something to worry about?
[LG G8 Guides, News, & Discussion] kesavanarix:
hi, anyone have image file A10 LG-G8X LMG850UM for T-Mobile TMO_US?
[LG G8 Guides, News, & Discussion] AsItLies:
No, not everything will work. The camera app on the kor rom is for the 3 rear lens version (only Kor has that). I've tried a few things to get that app to work with 2 lens version, or install the apk from us version, or modify configs... none of them worked.

The gcam ports work fine though. Also, could not get vowifi to work, it seems there are some basic system files missing for that and they won't install due to diff signature signing. But with just a few config mods you can get volte to work.

personally, I'm waiting until one of the us variant roms come out with a11.
[LG G8 Guides, News, & Discussion] abg360:
Bank apps works without problem, about crypto wallets I don't know because never used that, safety check pass everything, there is not opid mismatch error. The Eu ROM have Hidden Menu with field test to activate voLTE so the system is smooth and even can use velvet 2 pro apps in the phone, so I'm very satisfied only con I found is the Everytime I want to update to newer software version I have to reinstall and setup everything because I can't make a backup in mobile switch but that's only a spending time problem
[LG G8 Guides, News, & Discussion] syneoa:
^ thanks again, I have updated my post. I may try it soon, only worry is NFC paying which I use on my phone and am almost certain will not work because of failed key attestation.

I crossflashed from Sprint to Open US to Verizon A11. Upon booting A11, I get a NT error. NT. (331....) code. How do I fix this? I didn't experience it when I flashed from sprint to open us. I have all OP partitions of the three firmwares backed up
[LG G8 Guides, News, & Discussion] netmsm:
NT-Code relates to region and carrier and you can ignore the error if there's no problem with network.
[LG G8 Guides, News, & Discussion] Ebizza:
Okay. My internet is not as it used to be. Sometimes, i have to toggle flight mode on and off to make it work. You think the NT error is responsible for this?
[LG G8 Guides, News, & Discussion] netmsm:
So far as I know, the problem caused by NT-Code prevents from getting service. I doubt it that unusual internet connection is also caused by it.
[LG G8 Guides, News, & Discussion] chelsea67:
I've got nt error too, but everything works fine. So ignored that.
[LG G8 Guides, News, & Discussion] AsItLies:
There's a pretty easy way to fix the NT code error, but you need root and vbmeta needs to be disabled by fastboot commands.

In the OP section, using solid explorer, find a file called cust_path_mapping.xml. In it is usually just one line and it looks something like;

(this isn't it exactly, doing this from memory)

FF310120,FF=/OP/OPEN_US

All you have to do is jot down the nt error you're getting and add it to the above like so:

FF310120,FF=/OP/OPEN_US

FF312520,FF=/OP/OPEN_US

and that will fix it. Then you can eliminate that as a potential source of any network problems.

I finally unbrick my lg g8x its having lun 6 gpt error after following this tread steps but what i did at 1st deselected abl_a n abl_b in partition dl n that error dont arrive n it flashed after flashing gpt error went solve then follow this page step then deselect sid a n b this time its started but i lost imei n s/n
[LG G8 Guides, News, & Discussion] figer:
Hello,

Yesterday bricked my V500N. I tried to get ROOT, I followed the instructions on the 4PDA website (4PDA topic) and backed up the files

abl_a.bin

abl_b.bin

boot_a.bin

boot_b.bin

Abl_a.bin was different from abl_b.bin - it was 32MB and abl_b.bin was much smaller.

I was stuck with ADB fastboot because the "fastboot devices" command was not showing me the device, no matter how I installed the drivers.

So I decided to go back and uploaded abl_a and abl_b files using QFIL, but when I uploaded abl_a 32MB I had a "data overflow" message or something similar.

After disconnecting from QFIL, the phone remained off - once it vibrated when pressing and holding VOL +, VOL- and POW, and then it did not respond to any buttons, connected to a computer, for nothing ...

I disassembled the phone and managed to put it into EDL mode by shorting the points on the phone laminate (next to the loudspeaker connector).

https://xdaforums.com/t/for-hard-br...ized-by-any-computer-and-no-edl-mode.4299083/

I tried to start the phone using the instructions from this topic:

https://xdaforums.com/t/unbrick-all...-not-turning-on-and-no-download-mode.4363717/

but the phone still not responding to buttons and i couldn't turn it into download mode.

The phone only reacts to shortening the pins on the PCB.

After all these attempts, I stopped at the stage that either after shorting the pins I can enter EDL mode, or the phone is undetected by the computer and the phone screen displays immediately after connecting to USBcable: OPID Mismatched! and the phone does not respond to any buttons.

Can someone help me?

I am open to reasonable suggestions.
[LG G8 Guides, News, & Discussion] netmsm:
After altering abl the buttons stopped working, am I right?

1. Create

backup of LUN5

completely. It is vital!

2. Find and extract the KDZ which is currently running on the phone.

3. Restore the necessary partitions using this guide.

4. Follow this thread to flash the phone.

[LG G8 Guides, News, & Discussion] figer:
I apologize to you netmsm for my ignorance but unfortunately I do not fully understand the instructions - I do not modify phones as a hobby - I wanted to root the phone only to modify the DAC to make it sound better.

I made a LUN5 backup - all files from the phone.

I downloaded V500N30c_00_KT_KR_OP_1021.KDZ which I had installed.

I unpacked the DZ file and then unpacked the BIN files from it, but I still don't know what to do with them.

I can't find the manual you are writing about, I know the beginning of the KDZ extraction guide and I stay with the files:

Progress extractDZFlle Done !!

Abort extract partition file !!

Please, write what next, or at least provide a link to the topic?

How do I get the files visible in QFIL, i.e. abl_a, akmu_a, aop_a ...?

Do I have these files that I pulled from DA put in the BIN folder in QPST and your GPT file will do what it takes with them after using CMD and following the instructions?

Next - I understand that having a LUN5 backup I have to follow the "Ba" instruction, but at the end process I should use my files in QFIL and upload them for LUN5?

Next, from your instructions, I don't know if I should use your GPT file which has LUN0-LUN6 without removing LUN6 in it, or should I delete LUN6 - because QFIL shows that my LG has a maximum of LUN5? Should I modify the command for CMD and enter without LUN6?

Sorry to have so many questions but enjoyed the phone for 3 days, and wish to save it ...

If someone from Poland reads this topic, I can arrange a paid repair.
[LG G8 Guides, News, & Discussion] netmsm:
No friend, I should apologize.

Use the attached file to extract KDZ/DZ file. Read the help file.

Pick the necessary partitions which are mentioned here in the spoiler of part D.

I assume you have created backup of LUN5 and FTM.

Delete all partitions in partition manager.

Restore the necessary partitions

according to the guide

. You need to read the guide thoroughly.

The phone should be able to get into "download mode", so do it.

Flash it with LGUP in "partition dl" mode, unchecking sid partitions.

Note: The KDZ you are extracting should be the one that is already flashed on the phone.
[LG G8 Guides, News, & Discussion] figer:
I'm sorry - which attachment?

I backup-ed only files in LUN5 section. I will backup FTM also.
[LG G8 Guides, News, & Discussion] figer:

After flashing the phone you need to restore these partitions to have the IMEI and other identity information back. To do so, use qfil's partition manager.

[LG G8 Guides, News, & Discussion] figer:
Okay, so I have backed up all the files I downloaded before from my phone.

I understand that only some of them are needed, but the more the better.

I have a problem with the abl_a file - because it is huge and it was trying to restore it that caused the problem for me! I don't know if I mixed up something and it's not some other file?

I am enclosing its content - because it can be opened with 7zip.

They are saved on the Google drive and if I break something again and you need any of these files to help me - I'll just upload a single file and give you a link

But because the buttons did not work on my phone - I decided to test the "push button" stage in this method and because I have the phone dismantled - I disconnected the battery and a bit inconsistently with the instructions - while holding Volume UP +, I connected the battery and connected the USB cable and you know what?!?!

Voila :D

But now, when I try to upload the software, I have such a message. SID a and b unmarked.

I guess maybe because I uploaded these files from this tutorial - LGUP sees my phone as a different model?

https://xdaforums.com/t/unbrick-all...-not-turning-on-and-no-download-mode.4363717/

I have no idea, but I think there is progress ;)

How do I get around it?
[LG G8 Guides, News, & Discussion] figer:
I checked - the LMG850N - is the LG G8X.

Can I replace the files that I unpacked - IMG - with QFIL so that LGUP sees my phone as V500N?

Maybe some files from my backup will work?

Now as I know how to run it in DL mode, it's all simpler!

In this topic above - the author gave the unpacked files from the LG G8X for a replacement

Could any of the owners of LM-V500N get copies of their files - I quote from that post and give us the archive to replace?
