It looks like your timing with pressing the buttons isn't quite right, and the phone attempts to boot up instead of going into the download mode. Try to redo the step with deleting the partitions (because some partitions may be regenerated in the boot process, as noted in the guide) and rebooting into download. The point is to get it into the download mode immediately after restarting - you should not see that message if this is done right.

As for the fastboot, your phone should not even be able to enter the fastboot mode unless you flash the engineering abl image (this is part of the bootloader unlock process described in details in a separate guide).
[LG G8 Guides, News, & Discussion] dr.arest:
I’m sure the phone booted in download mode because the blue download mode logo appeared for a while.

I tried to restore partitions ftm, op_a, op_b, modem_a, modem_b, sid_a, sid_b from my backup.

It was a failure!

The phone gave no signs of life.

What I done i flashed original firmware LOCKED THE BOOTLOADER of dynamic partion .i unable to unlock the bootloader nor delete the dynamic partitions.every timewhen i try to boot fastboot it booted with fastbootd. what to do.. I am unable access "A" partion firmware and bootloader..now my phone running in dynamic partion os and bootloader fastboot d.

Wait for solution.
[LG G8 Guides, News, & Discussion] netmsm:
I wanted to know in case I might have some files for it but I do not.

First

create a backup of lun5 partitions and ftm

though if I were you I would make a full backup.

Then search for how to change the active slot and change it to the inactive side. Check if the phone starts. If not, you need to restore the necessary files from the same KDZ installed on the phone. For this, extract the KDZ and use qfil to restore partitions.

Here you can find some info about the necessary partitions and how to restore them.

Hi netmsm.

Iam currently using open kor android 10 firmware on my lm g820n, which was on skt firmware earlier, thanks to ur guide. Now that the lg g8 has received android 12 i tried to update it through check for updates on my phone and it shows that it's on the latest update, weird.

I just want to know which is the easiest way to get open kor android 12 on my device.

Is it possible to directly flash open kor android 12 according to the guide? OR should i flash skt android 10, then update to android 12 and then crossflash to open kor android 12?

Thanks in advance.
[LG G8 Guides, News, & Discussion] netmsm:
Hi sasindu =)

The message saying you're on the latest update also happens for me. It's common I guess.

Yes it is possible to flash Open KOR A12 following the guide and you do not have to go the second way to return to SKT and...
[LG G8 Guides, News, & Discussion] sasindu:
Thanks for the reply. Ill try with open kor android 12 then.

One more question netmsm,

Are these partitions automatically generated by the OS? And what does they do?

Thank you.
[LG G8 Guides, News, & Discussion] netmsm:
You're welcome bro =]

Partitions are created by GPT files. Each partition has a specific function which I don't know.

I have the LM-G820QM version, and I have previously cross flashed to the official Verizon ROM. This got wifi calling on this phone to work for me, but the Verizon ROM is hot garbage so I flashed back to the OEM ROM which of course broke wifi calling.

Is there anyway to Frankenstein together whatever modem/carrier stuff enables wifi calling on the Verizon ROM with the OEM ROM so I can get wifi calling without the trash Verizon ROM?
[LG G8 Guides, News, & Discussion] Surgemanxx:
It's all under questions,answer,and troubleshooting in the main post.Read this section here to fix the NT Code issues.

ERRORS, QUESTIONS, TROUBLESHOOTING

1. Can I crossflash V50, V60, G8X or other LG devices using this method?

I did it on V50. Maybe it'll work on your devices maybe won't. There's one way to find out; make

backup

and give it a try.

2. SN is gone, zero, etc.

Restore your original FTM.

3. I can't get into recovery.

Restore the original FTM.

4. I got NT-Code error.

It's been discussed many times in the thread and some solutions have been presented (such as this one, thanks to @animo214 and this, thanks to @kt-Froggy as well as this one, thanks to @StvOchi ). However, you can

ignore

it if the phone got network.

For open Canada,you'll need to add this NT Code to your FTM partition for the NT Code.If you can pull your FTM with Qfil,send it to me and I'll fix it for you.

[LG G8 Guides, News, & Discussion] Surgemanxx:
From what I have read and tried it's not possible!When the device boots and connects to the network,it sends data back to see what the actual firmware is running on the device and it enables features from there.I'm not saying there isn't a way,but from my experience it's almost impossible!
[LG G8 Guides, News, & Discussion] nortnil:

Hi guys.

I keep getting "data overflow" message when I try to load original FTM file in QFIL to restore my serial number. It's a small file, only 32 MB. Few months ago it worked smooth, no errors. What can be the reason? What can I try to fix this?
[LG G8 Guides, News, & Discussion] AsItLies:
One thing for sure, do NOT select 'continue anyway'.

When this happens it's usually you've either backed up the wrong partition and named it wrong or somehow, it's wrong.

If you select 'continue anyway' you'll overwrite the neighboring partition, and essentially brick the phone.

You have a mistake somewhere, figure out why that file is the wrong size.
[LG G8 Guides, News, & Discussion] tofik33`:
Hi.

Thanks for the answer. Of course I didn't proceed with flashing.

The file is correct, I kept it on my disk since I flashed it last time few months ago. I have backed up original FTM and modded one with NT-code error fix. None of them work now...

Just few minutes ago I dumped FTM which is currently on my phone and the file size is also 32 MB so there is no mistake on my side.

BTW does anyone know why the NT-code error remains even after flashing the original firmware back on the device? I'm just curious if there is a way to restore the phone to manufacture state.
[LG G8 Guides, News, & Discussion] Surgemanxx:
Pull the FTM and edit it in hex.Should be offset 14000 for the NT-Code.Make sure to paste write it and save.Write it back,should fix that.
[LG G8 Guides, News, & Discussion] AsItLies:
For some reason, unbeknownst to us, the qfil software is saying it's wrong. Did you use a usb 2.0 port when backing up / restoring? If not, it's entirely possible the backup is corrupt, or the restore attempt is sending it corrupted. The qfil software wasn't designed with usb 3.0 speeds in mind.

When you say 'flashing the original firmware' back on the device... how? Did you use the bkerler utilities to backup orig firmware? Or are you flashing a kdz? there's a big difference, the bkerler backs up ALL the original partitions, the kdz is only going to flash generic firmware, and not the original partitions like ftm etc that are specific to that device.

The nt-error code is pretty easy to fix, there's a specific file you have to edit, can't remember off the top of my head which one it is, would have to look if you want to go that route. But it's in the directory that has the oem partition and the file you edit exists now, and has a single line that points to that oem partition. You just add another line, which includes the nt-error code information, which will also point to that oem partition.

I can find more info on that if you want to go that route.

good luck
[LG G8 Guides, News, & Discussion] tofik33`:
Yeah, I know it's important not to use usb 3.0. I've read about that before I attempted to use QFIL :)

I thought flashing kdz file and choosing "refurbish" option in LGUP would be sufficient to make the phone like new one from factory. Thanks for clarifying.

I fixed the NT-code error by editing ftm file in hex editor. But as I mentioned before I cannot flash the file wiht QFIL anymore... Maybe I just try to edit the ftm file I dumped today.

Are you talking about this method or some other? The other method probably needs the phone to be rooted?
[LG G8 Guides, News, & Discussion] AsItLies:
Yes, it does need to be rooted. For sure, if you can edit the ftm file you recently dumped and you're able to flash it back, that would absolutely indicate the other ftm you have backed up, that you say is original, must have something wrong with it.

No, the 'refurbish' option doesn't set it 'completely' back to stock. There are 5 (I think) files that are 'permanent' to the phone, and shouldn't be changed by a 'refurb' or an update or xflash to other rom. Ftm, fsg, modem_a and modem_b and one other, forget.

But those are the files the bkerler utilities would back up, it backs up **everything**, that's why it's so highly recommended to do that backup.

cheers
[LG G8 Guides, News, & Discussion] Surgemanxx:
I would do a factory clear,and re-pull the FTM again and make the edits.If you try to edit the FTM manually in hex it will make the file size slightly larger and give you the error you're describing.Key thing when writing a new NT-Code to the FTM is copy and paste write it in hex so it doesn't increase in size at all.

4. Move "LGUP_Common.dll" and "UI_Config.lgl" into "common" folder. Change the attribute of "UI_Config.lgl" to read only.

the above is from the original instructions, how did you miss it? It says, explicitly, to use 'partition download' doesn't it? But you don't have that selection? And it's because you didn't follow the steps, like step 4 above.

[LG G8 Guides, News, & Discussion] Surgemanxx:
All that's correct!If you plan on cross flashing to the T-Mobile firmware you need to use Qfil and erase these partitions.FTM,OP_a,Op_b,Modem_a,Modem_b,Sid_a,and Sid_b.Once that's done,exit EDL mode then hold vol + to get back in to download mode.After that you can use the T-Mobile firmware,but flash it with partition download and check all but sid_a and sid_b.Then it will bypass the errors you're getting.
