[Tutorial] Rescue From HARD BRICK

[netmsm]

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=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.

 

[netmsm]

These codes are modified to work on LG V60, according to LG V60 PartitionList.xml provided by rifay78.
It is assumed that G8's and V60's necessary partitions are the same but in different locations.
Before using these codes make a full backup of your device.

For LG V50S go this post thanks to @Zenozero.

 

[netmsm]

GPT or LUN files for LG v50 are attached.
GPT files for G850X added.

 

[AsItLies]

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

 

[netmsm]

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.

SORRY FIXED I HAVE TO GIVE ADMIN ACCESS IN PROPERTIES
EXACTLY I HAVE TO PUT .\fh_loader.exe

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.

Is this warning normal?
11:25:16: WARNING: User specified --num_sectors=1024 but file only has 6 sectors. **Ignoring --num_sectors

I don't think so!
Where do you get this?

Trying to restore the GPT layouts with:
fh_loader.exe --port=\\.\com --sendimage=LUN6.bin --start_sector=0 --lun=6 --num_sectors=1024 --noprompt --showpercentagecomplete --zlpawarehost=1 --memoryname=ufs

COM port configured correctly, of course.
All the LUN files throw with warning, using QFIL 2.0.3.5 (linked above as QPST_QFIL_2.7.496)

My bad! Sorry, but it won't harm.
This is because of number of sectors that should be 6 for GPT files, all of them.
I'll correct them, thanks.

I was JUST gonna ask you if I could/should try that. I have a "burner" LG8x that I'm abusing for "educational" purposes.

Just dissect it like a lab rat
I did this to one G8 =)) it would take a revenge if it could've

Maybe 5 is the magic number? or SEVEN, SEVEN's the magic number! (name that 80's movie)

update; i removed the num_sectors and no warnings....seems like that should be ok.

 

[davembg]

@netmsm - out of curiosity, what did you use to make the LUN layouts?

 

[netmsm]

@davembg It's just a warning message saying it is ignored so no need to worry. I should check and find out about it.
LUNs can be dumped like other info/partitions and extracted from a KDZ.
If you wanna dump them, modify the restoring code by adding "--convertprogram2read" after port number. The next is to add "--num_sectors=6" after the number of LUN. The latter tells the program how many sector it should read.
For LUN0 it would become like this:
fh_loader.exe --port=\\.\com# --convertprogram2read --sendimage=LUN0.bin --start_sector=0 --lun=0 --num_sectors=6 --noprompt --showpercentagecomplete --zlpawarehost=1 --memoryname=ufs

Now I got it; Idiot Meisam! In restoring, there is no need to specify how long the file is and so you did correctly by removing "num_sectors".

I followed the guide and am having the same issue. The screen flashes the boot logo for a quarter of a second before shutting off for about a second and repeating that until the battery dies. Any ideas would be appreciated, because I am at my wits end. if it helps I have the T-Mobile unlocked version. Also, in LGUP, it says the version is G820UM20j. The kdz I have tried flashing is G820TM20j. Thank you for your help!

Did you try to get into download mode?
For now just restore FTM.

 

[Zayveeo5e]

I can get into download mode, and flash a kdz. I still can't get past the flashing boot logo though. I have tried restoring the partition backups, but that didn't help either.
