Don't worry!
Everything's gonna be alright ;)

You may accidentally erase all partitions and GPT on your phone. Nothing is shown in "Partition Manager". Since there's no Rawprogram XML file we need an alternative method to get the phone back on again.
This tutorial shows how to recover from a hard brick state. Be aware that identity data of the phone are stored in LUN5 (modemst1, modemst2, fsg and fsc) and are incapable of recovering. So, you need to repair IMEI.
Except using IMEI repair tool box, there is only one possible way to rewrite IMEI but as far as I know the phone will throw an error that this phone is permanently locked.
On the SDM855 flash we have 7 LUNs. Each Lun is devided into several partitions where data are stored. Some of the partitions are necessary in order that phone can turn on. They are in LUN0, LUN1 and LUN4. If you have no backup you need to extract the necessary or all partitions from a KDZ. So, do a search for how to extract the new KDZ files, learn and do it. There are some difficulties with extracting OP partition so make sure you do it correctly. Since, it's been explained in this forum I'm not gonna re-explain anything.
So, let's get started =)


Requisites
QPST and Qualcomm USB Driver (get)
LGE SM8150 Firehose (get)


Preparation
1. Install QPST and Qualcomm USB Driver.


Basic Steps
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". Keep the "Partition Manager" for the entire process.

A) I have a backup.
1. Download GPT files (get).
2. Flash GPT files using FH_Loader (Part C).
3. Flash the necessary partitions using FH_Loader (Part D) or restore partitions using "Partition Manager". ONLY USE YOUR BACKUP FILES.
4. Close "Partition Manager" wait for about 5 seconds then press and hold Vol- and Power for 10 seconds.
5. After restart quickly release buttons and press and hold Vol+ to get into "Download Mode".
6. Flash any KDZ but use instruction in this thread (Part C) to avoid "OPID Mismatched Error".

B) I have no backup.
Ba) I was not on Sprint or ATT last time before hard brick.

1. Download GPT files (get).
2. Flash GPT files using FH_Loader (Part C).
3. Flash the necessary partitions using FH_Loader (Part D). You need to extract and use the necessary partitions from the same KDZ which you had flashed on the phone last time before hard brick or it may not work.
4. Close "Partition Manager" wait for about 5 seconds then press and hold Vol- and Power for 10 seconds.
5. After restart quickly release buttons and press and hold Vol+ to get into "Download Mode".
6. Flash any KDZ but use instruction in this thread (Part C) to avoid "OPID Mismatched Error".

Bb) I was on Sprint or ATT last time right before hard brick.
1. Download GPT files (get).
2. Flash GPT files using FH_Loader (Part C).
3. Flash all the partitions using FH_Loader, just side a, extracted from any KDZ (Part E). To test your luck, extract and use the necessary partitions of an A10 KDZ.
4. Close "Partition Manager" wait for about 5 seconds then press and hold Vol- and Power for 10 seconds.
5. After restart quickly release buttons and press and hold Vol+ to get into "Download Mode".
6. Flash any KDZ but use instruction in this thread (Part C) to avoid "OPID Mismatched Error".

C) Flashing GPT Files.
1. Move GPT files to the "bin" folder in QPST installation folder.
2. While you are in "bin" folder, open CMD there.
Note: Remember you need to have "Partition Manager" opened.
3. Find the port number of the phone from "Device Manager".
4. Add the the number (port number) right after "fh_loader.exe --port=\\.\com" in the following codes.
4.1. For example, mine is "3" so it would be "fh_loader.exe --port=\\.\com3".
fh_loader.exe --port=\\.\com --sendimage=LUN0.bin --start_sector=0 --lun=0 --noprompt --showpercentagecomplete --zlpawarehost=1 --memoryname=ufs

fh_loader.exe --port=\\.\com --sendimage=LUN1.bin --start_sector=0 --lun=1 --noprompt --showpercentagecomplete --zlpawarehost=1 --memoryname=ufs

fh_loader.exe --port=\\.\com --sendimage=LUN2.bin --start_sector=0 --lun=2 --noprompt --showpercentagecomplete --zlpawarehost=1 --memoryname=ufs

fh_loader.exe --port=\\.\com --sendimage=LUN3.bin --start_sector=0 --lun=3 --noprompt --showpercentagecomplete --zlpawarehost=1 --memoryname=ufs

fh_loader.exe --port=\\.\com --sendimage=LUN4.bin --start_sector=0 --lun=4 --noprompt --showpercentagecomplete --zlpawarehost=1 --memoryname=ufs

fh_loader.exe --port=\\.\com --sendimage=LUN5.bin --start_sector=0 --lun=5 --noprompt --showpercentagecomplete --zlpawarehost=1 --memoryname=ufs

fh_loader.exe --port=\\.\com --sendimage=LUN6.bin --start_sector=0 --lun=6 --noprompt --showpercentagecomplete --zlpawarehost=1 --memoryname=ufs
5. Modify the codes and use them in the CMD.
6. If anything goes wrong you may get the "error" message instead of "done" message.

D) Flash The Necessary Partitions.
Note: Necessary partitions are the ones that make the phone capable of turning on and going to Download Mode.

5. Modify the codes and use them in the CMD.
6. If anything goes wrong you may get the "error" message instead of "done" message.


Note: LUN files I provide have ".bin" extension and other files should have ".img" extension, otherwise you need to modify the codes.

Hey man, I need help with my bricked LG-V50.. I have alot of 4K videos on this phone. I think the storage capacity got way too full and couldn't handle the background tasks that is mainly running the phone which caused it to bootloop. It began overheating, constant freezing, and I just can't even get past my lockscreen as it would just restart. Even charging the phone wouldn't help, it would just restart until it would ran out of battery. I haven't tried anything that would cause this like rooting the phone or flashing a new ROM because I have no experience on anything like that. I would just like to get my phone back to stock and get it running again. I tried to do a factory reset with the power and vol+ button and after a few seconds it failed and began bootlooping again.

I can access EDL and have managed to get to fastboot by following this guide to unlocking bootloader https://forum.xda-developers.com/t/...nlock-and-magisk-root-using-firehose.4221793/

But this is where I am stuck at right now

fastboot-bootloader-locked-and-slot-jpg.5194783


I have accessed the fastboot but the bootloader is locked, and I have tried to do the OEM unlock command on ADB but it says FAILED. It's probably because I haven't turned on the OEM unlock option in the developer options. I'm really stuck right now any help would be much appreciated.. thanks.

LG G8X ThinQ
hello I have a g8x sprint, I deleted all the partitions by accident but I made a backup of the 7 partitions that need to be deleted for crossflash, does step A work for me? another doubt by chance do you know how to identify the partitions with the name that QFLI gives them? is that when I save the backup I don't rename them, if the above doesn't work for me, it would be step Bb right? do i need all partitions? I'm looking for a tutorial to extract the kdZ but I can't find it, any ideas?

You do not have backup, so this maybe useful for you plus the FTM you've backed up. Try Ba steps, hope it works.

LG G8X ThinQ
You do not have backup, so this maybe useful for you plus the FTM you've backed up. Try Ba steps, hope it works.
I was able to solve the download mode by extracting a kdZ from a10 and restoring all the partitions with QFIL, but now I have the problem with imei and nt code, I was able to write the imei but not the ntcode and still no service, any possible solution?

PD the fingerprint sensor also gives an error, I imagine that it is caused by the nt code, yes?

We've had much discussion about IMEI and NT Code in this thread, you may found them.

I do not think so!

    Do you think I can enter edl mode through test point?
    Absolutely.
    Before that, try this: connect USB cable and hold power and vol- then burst vol+ for many times at least for 30 seconds.

    I've extracted the KDZ A11, but some of the files are missing, or am I missing something... right now, I only can gain access to EDL, can't enter download mode or even the splash screen. Right before I flashed, I was on 20b A10(sprint), so I flashed a backup (A11) thinking that it should work fine, but I was wrong. I did backup my LUN 5 just incase, I didn't delete any partitions. I should have sticked the A10 if I knew it was gonna be this hard.
    Read and follow instructions. If you need backup files of Sprint ROM check this.

    So bad news, my G8X no longer show any signs of life, can't boot into EDL mode anymore, reinstalled the driver and QPST, I guess my only option now is opening the back and short the EDL pins.. or is there another way around this?
    Plug in the USB cable and hold power and vol- then rapidly press the vol+, do it a lot.

    follow your guide I managed to turn on the phone but it gives me the permanent lock error I have and I do not have a backup how can I solve it
    LUN5 partitions must be restored using backups of the same phone if it's not available the only way to solve permanent lock is to perform Repair IMEI using Octopus box.

    I need the LUN files for the G850UM (SPRINT) do you have them?
    Download from post #3.

    Don't worry!
    Everything's gonna be alright ;)

    You may accidentally erase all partitions and GPT on your phone. Nothing is shown in "Partition Manager". Since there's no Rawprogram XML file we need an alternative method to get the phone back on again.
    This tutorial shows how to recover from a hard brick state. Be aware that identity data of the phone are stored in LUN5 (modemst1, modemst2, fsg and fsc) and are incapable of recovering. So, you need to repair IMEI.
    Except using IMEI repair tool box, there is only one possible way to rewrite IMEI but as far as I know the phone will throw an error that this phone is permanently locked.
    On the SDM855 flash we have 7 LUNs. Each Lun is devided into several partitions where data are stored. Some of the partitions are necessary in order that phone can turn on. They are in LUN0, LUN1 and LUN4. If you have no backup you need to extract the necessary or all partitions from a KDZ. So, do a search for how to extract the new KDZ files, learn and do it. There are some difficulties with extracting OP partition so make sure you do it correctly. Since, it's been explained in this forum I'm not gonna re-explain anything.
    So, let's get started =)

    For other models than LG G8 please read post #2.

    Requisites
    QPST and Qualcomm USB Driver (get)
    LGE SM8150 Firehose (get)

    Other Downloads
    Sprint dumped ROM (get) [optional]
    Necessary files for LG G8X (get from this post) thanks to @davembg [optional]
    LG V50 GPT files (get) [optional]

    Preparation
    1. Install QPST and Qualcomm USB Driver.


    Basic Steps
    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". Keep the "Partition Manager" for the entire process.

    A) I have a backup.
    1. Download GPT files (get).
    2. Flash GPT files using FH_Loader (Part C).
    3. Flash the necessary partitions using FH_Loader (Part D) or restore partitions using "Partition Manager". ONLY USE YOUR BACKUP FILES.
    4. Close "Partition Manager" wait for about 5 seconds then press and hold Vol- and Power for 10 seconds.
    5. After restart quickly release buttons and press and hold Vol+ to get into "Download Mode".
    6. Flash any KDZ but use instruction in this thread (Part C) to avoid "OPID Mismatched Error".

    B) I have no backup.
    Ba) I was not on Sprint or ATT last time before hard brick.

    1. Download GPT files (get).
    2. Flash GPT files using FH_Loader (Part C).
    3. Flash the necessary partitions using FH_Loader (Part D). You need to extract and use the necessary partitions from the same KDZ which you had flashed on the phone last time before hard brick or it may not work.
    4. Close "Partition Manager" wait for about 5 seconds then press and hold Vol- and Power for 10 seconds.
    5. After restart quickly release buttons and press and hold Vol+ to get into "Download Mode".
    6. Flash any KDZ but use instruction in this thread (Part C) to avoid "OPID Mismatched Error".

    Bb) I was on Sprint or ATT last time right before hard brick.
    1. Download GPT files (get).
    2. Flash GPT files using FH_Loader (Part C).
    3. Flash all the partitions using FH_Loader, just side a, extracted from any KDZ (Part E). To test your luck, extract and use the necessary partitions of an A10 KDZ.
    4. Close "Partition Manager" wait for about 5 seconds then press and hold Vol- and Power for 10 seconds.
    5. After restart quickly release buttons and press and hold Vol+ to get into "Download Mode".
    6. Flash any KDZ but use instruction in this thread (Part C) to avoid "OPID Mismatched Error".

    C) Flashing GPT Files.
    1. Move GPT files to the "bin" folder in QPST installation folder.
    2. While you are in "bin" folder, open CMD there.
    Note: Remember you need to have "Partition Manager" opened.
    3. Find the port number of the phone from "Device Manager".
    4. Add the the number (port number) right after "fh_loader.exe --port=\\.\com" in the following codes.
    4.1. For example, mine is "3" so it would be "fh_loader.exe --port=\\.\com3".
    fh_loader.exe --port=\\.\com --sendimage=LUN0.bin --start_sector=0 --lun=0 --noprompt --showpercentagecomplete --zlpawarehost=1 --memoryname=ufs

    fh_loader.exe --port=\\.\com --sendimage=LUN1.bin --start_sector=0 --lun=1 --noprompt --showpercentagecomplete --zlpawarehost=1 --memoryname=ufs

    fh_loader.exe --port=\\.\com --sendimage=LUN2.bin --start_sector=0 --lun=2 --noprompt --showpercentagecomplete --zlpawarehost=1 --memoryname=ufs

    fh_loader.exe --port=\\.\com --sendimage=LUN3.bin --start_sector=0 --lun=3 --noprompt --showpercentagecomplete --zlpawarehost=1 --memoryname=ufs

    fh_loader.exe --port=\\.\com --sendimage=LUN4.bin --start_sector=0 --lun=4 --noprompt --showpercentagecomplete --zlpawarehost=1 --memoryname=ufs

    fh_loader.exe --port=\\.\com --sendimage=LUN5.bin --start_sector=0 --lun=5 --noprompt --showpercentagecomplete --zlpawarehost=1 --memoryname=ufs

    fh_loader.exe --port=\\.\com --sendimage=LUN6.bin --start_sector=0 --lun=6 --noprompt --showpercentagecomplete --zlpawarehost=1 --memoryname=ufs
    5. Modify the codes and use them in the CMD.
    6. If anything goes wrong you may get the "error" message instead of "done" message.

    D) Flash The Necessary Partitions.
    Note: Necessary partitions are the ones that make the phone capable of turning on and going to Download Mode.
    abl_a
    akmu_a
    aop_a
    cmnlib_a
    cmnlib64_a

    1. Move files to the "bin" folder in QPST installation folder.
    2. While you are in "bin" folder, open CMD there.
    Note: Remember you need to have "Partition Manager" opened.
    3. Find the port number of the phone from "Device Manager".
    4. Add the the number (port number) right after "fh_loader.exe --port=\\.\com" in the following codes.

    5. Modify the codes and use them in the CMD.
    6. If anything goes wrong you may get the "error" message instead of "done" message.

    E) Flash All Partitions.
    1. Move files to the "bin" folder in QPST installation folder.
    2. While you are in "bin" folder, open CMD there.
    Note: Remember you need to have "Partition Manager" opened.

    5. Modify the codes and use them in the CMD.
    6. If anything goes wrong you may get the "error" message instead of "done" message.


    Note: LUN files I provide have ".bin" extension and other files should have ".img" extension, otherwise you need to modify the codes.

    the partitions which carry imei / s/n are ftm, fsg, modem, modemst1 and modemst2.
    FTM is a temp place and its data are regenerated after flashing the phone. Changing IMEI in FTM will not change the phone IMEI.
    FSG is the backup of Modemsts. Repairing IMEI process can alter Modemsts but not FSG.
    LG has put a new lock in NVM to prevent identity data from getting changed. In addition, the bridge to Modemsts is Modem partition which carry another lock called IMEIPROT.
    When we erase all partitions, NVM is cleared but IMEIPROT still exists in Modem. The only way to rewrite IMEI is to modify Modem by removing IMEIPROT. However, losing NVM will awake another lock which prevents Modem from detecting Sim, resulting in the error "this phone is permanently locked" even after rewriting IMEI.

    So, I bricked my LM-850UM...yeah, I know.
    I downloaded (3) different KDZ files, extracted them and the DZ files.....
    I did not find the files needed to restore to "download" mode - and my partitions don't "line up" any longer.
    Does anyone have, or know how to retrieve, the partition imgs noted in the "Spoiler" for Step D?
    abl_a, akmu_a, aop_a.....etc

    Update - I did find the files I needed...they are attached. Phone is now it download mode.

    Nice write up. Pretty sure the partitions which carry imei / s/n are ftm, fsg, modem, modemst1 and modemst2.

    Those are the partitions they indicate on v40 tele group anyway, last I looked.

    cheers

    Did you do it according to the suggested instructions?
    Would you try Korean A9?
    I tried flashing open_kr A11 and it actually booted. Thank you for your help!
