They said that they can't find my phone, anything I can do?
Seems like there's a problem in the driver. Check for USB port and cable and reinstall the driver.
Reinstalled the driver and downloaded the KDZ, but instead this occurs.
What should I do with this?

Bizarre!
If I were you I would make a full backup and then flash via "chip erase".
Just want to say thanks...your instructions were right on perfect and corrected my LG G8 NT-Code Error...good day mate!
i cant download the LGUP 1.16.0.3 ... This site can’t be reachedHi there
Thanks to all other guys here who have made helpful development to tame this beautiful =)
To crossflash models other than LG G8 please read post 3.
Before asking any question please read the troubleshooting section at the bottom of the page.
If you still need some specific help I would appreciate if you bring it up just in the thread instead of sending direct messages.
LG has made things difficult in flashing custom and even stock roms by this new OPID thing! It prevents us from crossflashing but we have been able to use TWRP and change the system and some other partitions to have a different rom. We had to make some changes into OP partition using HxD editor.
But now, through this tutorial, we're able to flash any rom without the need to change OPID in OP partition. Also, there is no need to root or unlock boot-loader.
I was successful to do this on some G8 (LMG820UM) but I AM NOT RESPONSIBLE FOR ANY HARM TO YOUR PHONE!
By continuing to read the following instructions you are actually accepting the risk.
IMPORTANT!
first, MAKE A FULL BACKUP OF ALL PARTITIONS; and I mean it!!!
at least, for your sake, make a backup of "modemst1, modemst2, fsg, fsc, ftm" partitions, for emergency.
Requirements
QPST and Qualcomm USB Driver (get)
LGE SM8150 Firehose (get)
LGUP 1.16.0.3 (get)
LGUP_Common.dll (get)
UI_Config.lgl (get)
LG Mobile Driver 4.4.2 (get)
Preparation
1. Install QPST and Qualcomm USB Driver.
2. Install LGUP.
3. Find the folder named "model" in the installation directory of LGUP, then Create a folder named "common" in the "model" folder.
4. Move "LGUP_Common.dll" and "UI_Config.lgl" into "common" folder. Change the attribute of "UI_Config.lgl" to read only.
5. Install LG Mobile Driver 4.4.2.
Steps
A)
1. Open QFIL.
2. Change "Storage Type" to UFS.
3. Select "Flat Build".
4. Browse for "LGE SM8150 Firehose" and pick it.
5. Now, connect the phone to PC and boot into EDL mode.
6. Open "Select Port" and select the phone, press OK.
7. In "Tools" open the "Partition Manager".
B)
!!!BE CAREFUL TO DO EXACTLY AS THE INSTRUCTIONS SAY OR YOU WILL BRICK THE PHONE!!!
1. Make a backup of and erase these 7 partitions: FTM, Modem_A, Modem_B, SID_A, SID_B, OP_A, OP_B.
1.1. You have to left-click on a partition then right-click on it and select "Manage Partition Data".
1.2. In the pop-up window, you have 4 choices: I. Erase (to erase data on the partition), II. Read Data (to dump or back up the partition), III. Load Image (to restore the partition), IV. Close (to close the window).
1.3. First dump/back up the partition by choosing "Read Data" then Erase it.
2. Close the "Partition Manager" window.
3. Wait for 5 seconds then press Vol- and Power until it restarts.
3.1. Immediately after rebooting, Release the Vol- and Power buttons and press Vol+ to get into Download Mode.
Note: Do not let the phone to begin to boot! If it begins to boot, it may regenerate the SID and FTM partitions data and so you need to redo the whole step B.
C)
1. Open LGUP.
2. Pick your favorite KDZ.
3. Select "PARTITION DL".
4. Press Start. And a pop-up window will appear. In this window you can select which partitions to be flashed.
5. Here, uncheck these partitions: SID_A and SID_B. It will make it able to bypass the OPID Mismatched Error.
6. If you are in Sprint or other platforms you will get the message whether to change the model or not. Of course you know what to do =)
after completing the process it will boot up in some minutes and before starting the customization it will do one restart. just be patient.
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.
Note: You need to disable verity on the phone in advance otherwise changes in cust_path_mapping.cfg won't be saved.
5. IMEI is lost, zero, null etc.
Restore LUN5 partitions. If you have no backup it should be repaired using Octopus box. Go to 16.
6. I got "permanently locked" error.
This is because of IMPL lock and you have to restore LUN5 partitions. In case of having no backup you should use Octopus box.
7. All partitions are deleted accidentally.
Follow this instructions.
8. I need to get into PDM mode.
Unzip and restore the attached PDM to FTM partition. Remember, you need to restore your FTM to get into OS.
9. Can I use another phone's LUN5 backup?
NO.
10. Can I use another phone's FTM backup?
Yes. All partitions can be restored from another phone's backup except LUN5 partitions.
11. My phone is stuck in boot-loop.
Restore the original FTM and if it doesn't help redo the whole crossflash process and use a different KDZ this time.
12. Which KDZ is the best (for any matter of use)?
I do not know.
13. Can I crossflash from any source variant to Korean variant or vice versa?
Yes it is possible but you may get error on opening stock camera application because of hardware differences. There are some methods to solve the issue which you can search and find them.
14. Can I downgrade using this method?
Yes.
15. I erased partitions (ftm, op_a, op_b, modem_a, modem_b, sid_a, sid_b) but it still does not let me to crossflash.
Redo the whole process and this time make backup of and erase these partitions too, on both sides A and B: vendor, product, system, boot and userdata. Do not make backup of userdata partition.
16. How can I write IMEI?
A) Dump modem_a and create a copy of it. Then open it in UltraISO and remove IMEIPROT files from image folder. Save and restore it in place of modem_a and modem_b partitions.
B) Make backup of FTM and then flash or restore the PDM file (attached) into your ftm partition. Restart the phone; you'll get into PDM mode.
C) Open Tutty (attached). Select "Serial" in protocol and the proper port of your phone's modem driver. Click open. To test if you have selected the proper port number type "at" and hit enter it should respond"ok". Type the code at%imei=# (replace # with your IMEI) and hit enter. It doesn't matter you get "error" or "ok" after that, just check if IMEI is written via this code at%imei=?. If IMEI is written so you'll have the right MEID and ESN too.
D) Restore the original ftm and modem_a in place of modem_a and modem_b. Restart the phone.
I've already tested this method on V30, V50 and G8. Remember, if the phone has IMPL lock it'll throw "perm. locked" error even if you have written the IMEI.
17. I have lost GPT files of my LG G8, G8X, G8S, V50, etc. and Qfil partition manager does not show anything in the list.
You need to flash GPT files to your device with fh_loader (see this, part C). For that matter use KDZ_Tools to Extract DZ from a KDZ of your device. Then extract the DZ using -c at the end of extracting command. For example: unkdz -f FILE_NAME.kdz -c. It will extract all files besides all GPTs.
18. Which are the LUN5 partitions?
SM8150 has 7 physical partitions known as LUNs which are numbered from 0 to 6. Each LUN is split into several partitions. In Qfil Partition Manager you can see all partitions except those of LUN3 and LUN6 which are hidden. The number of LUNs are shown under the first column named LUN. Therefore, all partitions in front of number 5 are LUN5 partitions.
Hey! Did you manage to flash your phone? I too have lg g8x 901lg model number softbank ver. And I would like to update to a12 by flashing...so did you flash it? Did it work?
Hello dudes I I have LG v60 Docomo version A51L in qfil mode I can t find OP_A and OP_B bin data file...is there any other name for Japanese version
After erasing FTM, Modem_A, Modem_B, SID_A, SID_B, OP_A, OP_B partitions I tried to enter Download mode.
But the following message appears:
What do you advise me to do?
But the following message appears:
Also in fastboot mode thee device is not visible in
fastboot devices output.What do you advise me to do?
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).
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.

Wait for solution.
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.
Lg v50 sprint I messed up system file. Can someone please send me the stock firmware?
I didn't find it ?

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.1Yeah, 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?
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.
cheers1
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.Yeah, I know it's important not to use usb 3.0. I've read about that before I attempted to use QFIL

So, we just got this sorted. Thanks to SGMarkus as he mentioned it's the ftm partition that controls recovery access and fastboot access. So, with the newly flashed kdz, as it is, you can't even get to fasboot although u flashed the eng abl to it.
But! Restore your old ftm, after flashing, and then you'll get access to both recovery and ability to get to fastboot after flashing eng abl.
cheers!4Some pictures of flashing my LMG820UM, unlocked from Sprint, into OPEN_CA 20j. In normal mode you cannot flash SPR_US to OPEN_CA which is shown in the pictures. But using this thread instruction it allows to flash, even it asks to change the model from SPR_US to OPEN_CA
Until performing the instructions, it shows the "id: 2(SPR_US)" on the Download Mode screen, but after that it cannot recognize the phone model id and shows "id: 0()"
Have fun ^_^4First off, big THANKS to the OP (netmsm) and other people who contributed to this thread and made this guide very clear and useful!
So, after perusing this thread for a long time, trying to understand the ins and outs of the process and any possible snafus, I decided to take the plunge after the Open_CA A12 (40a) got released recently, and to flash it onto my G8 originally from US Cellular. The crossflash went smoothly with no issues at all. A nice surprise was that the BL remained unlocked - I was prepared to go through the whole unlocking process again before rooting, but didn't have to. I got the empty S/N (easy fix), and the infamous NT-Code error. This is where I got stuck for a while. I tried fixing it by editing the cust_path_mapping.cfg file as suggested in the thread. The problem is that I couldn't save the changes in that stupid file by using ANY root explorer/editor! Tried half a dozen different apps with no luck at all. BTW, anyone has any ideas what I may have been doing wrong?? Yes, I am properly rooted with Magisk.
Anyway... Everything worked fine on the phone, but that lame error was really getting under my skin - I could have ignored it, but I hated not being able to get rid of it. So... After more reading, I came across some info on hex-editing the FTM partition (in a totally unrelated topic). The NT-Code in FTM binary is stored at the offset 00014000. My error message was referring to the code "FFFFFF,85". The original cust_path_mapping.cfg file (which I couldn't edit) had a line referring to "FFFFFF,82". So, having all backups available, I decided, just for the heck of it, to change the last digits of the NT-Code in the FTM partition to match the "82" listed in the file. What could go wrong? I can always restore a backup... After flashing the edited FTM in QFIL, rebooted the phone, and - bingo! The NT-Code error was gone, and the phone was still fully functional. This was my happy face after spending a good hour and a half trying to get rid of it, and finally succeeding:
Cheers, and thanks again for all the info!4
