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.
howw did you extract the neccessary files? ive tried 2 different kdz but i havent found em....anyhelp would be appreciated.

EDIT:
I found the correct programs to extract the kdz

Thanks very much. Can you tell me the exact model of the v50 from which you shared the LUN partition tables???
You're welcome =)
It's been V405 I think!
I extracted my kdz, there are a total of 17 neccessary partitions as per your guide, but i can only find 15 files in my kdz. I dont have the ''keymaster'' and ''power'' files......what do i do? can i boot without these 2??
I haven't worked on V50 for that matter.
But you can give it a shot and if you do that please inform us of result.

I flashed the 15 files but no luck, it still boots only in edl...nothing else...
btw, v405 is a v40 model, idk if the partition tables are same for v40 and v50.
its either not booting because that the LUNS are from v40 and not from v50, or because im missing 2 partitions to flash, or because of both reasons.

It will eventually work, but i guess ill have to try with a v50 LUN ( i think it might work) and ill try to find a way to get the other 2 missing partitions....If you can help i'll appreciate it!
Its a bit of a problem becuase it is my only mobile device:confused:

another thing to ask:
you separately provided me the v40 files, but btw, the ones you origianly posted as GPT files, in the first post, what mobile exactly are they from?

just asking to try em if they seem better for my v50!

That's right, but it was a typo. The model was LMV450.
oh thats good then , means that I only need 'keymaster' and 'power' partitions to make it work ig? are you sure that missing a single file from the neccessary partitions would make the phone un-bootable?

Edit:
last time i only extracted the neccessary files from my android 10 kdz for v500N
with python scripts, and i didnt find keymaster and power. But now i just extracted the whole kdz- i mean every partition, and I got the missing 2 partitions. Ill update after flashing these two.

There should be these two!
well after extracting every partition from the kdz i did find them....ill update after flashing btw do i have to close and reopen partition manager after flashing LUNS or do i have to flash the luns and partitions in one go??? Which method would be more successful??
EDIT:
i tried flashing both in one go, but phone still doesnt boot anything except edl...

Makes no difference.

Maybe you should flash all partitions.
i just spent an hour flashing every sing partition i extracted , and it finnaly booted!
battery is too low rn, ill update if it bootloops or goes into dl mode etc...

EDIT : I tried booting it and it keeps bootlooping . it stays on lg v50 logo for barely a second and reboots.....and when i try to go to download mode by pressing volume+ , it show donload mod escreen for a split second and goes staright to fastboot mode

EDIT 2 :
i locked the boot loader with fastboot, thinking it might fix the problem, but instead it gives me a red case

Flash the attached file to FTM.

sorry my man college started the next day and i couldnt get free...I tried yout ftm file but it didnt help, but i manually erased all flash and then reflashed the luns u provided, and loaded all partitions from an extraced kdz, and after that it got straight to download mode! So yep i flashed the stock kdz and it was good to go!

thanks very much bro, you saved lives and I also learned a lot.
couldve sent you a tip but you see im still studying. Appreciate your efforts man! see you soon!

Hello =]
You just need to extract a Verizon KDZ. Search for and download one then extract it using KDZExtractor.
Before doing anything, make backup of LUN5 partitions and FTM.

    bro i restore imei by editing meodem.bin

    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.

    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

    laf_a
    power
    tz_a
    uefisecapp_a
    vbmeta_a
    xbl_a
    xbl_config_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.
    4.1. For example, mine is "3" so it would be "fh_loader.exe --port=\\.\com3".

    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!
