@netmsm

Hi Friend,

Thank you very-very much for this great, deeply technical and detailed tutorial!!!

Initially, my LG G8 did not even boot into EDL/Qualcomm 9008 mode, after I accidentally deleted all the partitions in QFIL... I was able to successfully recover it from that Hard Brick/Dead state following this tutorial! Luckily, I also had a backup of my EFS (NV: modemst1, modemst2, etc.) partitions and fully recovered IMEI and phone functionality, as well.

I have also used another great tutorial (mentioned below) to enter into EDL/9008 mode by disassembling my phone and shorting two Test-points on the motherboard...

And I just want to share a few very important findings from my experience for the folks in a similar situation and face these not obvious issues during the Hard Brick Recovery process:

1. At first, I had GPT partition table in place In QFIL Partition Manager, and it looked right, but a few attempts of writing correct .bin files to necessary partitions did not give any results... Then I deleted the partition table, and re-created it using LUN files provided here (flashing LUN0 to LUN6 .bin files). And only after that the process of writing necessary partition worked properly!!!

2. After fixing necessary partitions with QFIL/fh_loader, the Test-point method to enter EDL/9008 mode does not work anymore!!! So, you can use this as an indicator of a successful write into necessary partitions.

3. If the Test-point method of EDL/9008 mode activation is used, the battery can (and should?) be disconnected: mine recognized in EDL/9008 mode and worked just fine in QFIL with the battery disconnected! And it is also much safer to power-off the main circuitry of the phone, especially when operating there with metallic tweezers! I have also isolated/covered SMD components around the Test-points with adhesive tape.

4. G8's volume down button (and only it!!!) does not work with the back plastic cover/wireless charging coil removed!!! So, we can not use button combination to reboot into EDL/9008 mode or exit from Download mode without that charging coil/plastic cover piece in place! How do I know? :)

5. Auto-brightness feature does not work with the back plastic cover/wireless charging coil removed!!!

6. It is not possible to enter into Download mode with the battery disconnected: If it was disconnected (for safety reasons), when activating EDL/9008 mode with Test-points, then reconnect it prior to leaving EDL/9008 mode and only then enter into Download mode!

Again, thank you very much for the amazing work done and shared here! And I wish you all the best!

Regards,

Taron

File backup xml -> partition needed to enter Download mode of lg v50s here https://drive.google.com/file/d/1FyisFVb9GqypBMTeep7CLkt5nE4YYVyU/view?usp=sharing

0. Consult the recovery method of lg v50 or other machine and find the program file to install. QFIL and LGUP or LG Drive.

- Select port

- select filehost

- select build type - fast build:

1. go to load xml.

2. select the extracted lg backup file and select it

all .xml files select open

3. choose cancel

4. choose download

5. wait for it to load

6. When done, press the volume button - at the same time with the power button for about 12 seconds

release, wait 10 20 seconds if no response press again. If it is up, the logo will appear and then turn off. Press and hold volume + button to enter downloade mode and then go to lgup up to rom.

7. In LGUP when pressing Start, there will be a notice board, please select Yes.

Many thanks, my LG V50s now can charging.

But now, my LG v50s is networklocked, IMEI is 0, NTCODE is mismatched, now can I solve this problem? thank much
[LG G8 Guides, News, & Discussion] faethuin:
any solution for imei 0, no s/n, ntcode 0, no backup of partitions of the original before unbrick?
[LG G8 Guides, News, & Discussion] Cryomichel:
OK so while trying to follow this guide I erased all the flash by mistake.... Then, I followed this thread to rescue from HARD BRICK . Luckily, I did a backup of EVERY SINGLE partiton in my previous attemp to crossflash the phone. The problem is when I arrived to step B)3.1 of the OP Mismatch thread the phone NEVER turned on again..... I tried everything I knew, holding vol - & PWR as long as I can, changing usb port, plugging the phone whille pressing volume up but the windows usb sound never happenend again, not able to go to either download or EDL mode..... Some people in this thread had the same issue and get the EDL mode again by miracle so if anyone could help me I would be delighted to get the phone to work again as it is for now a huge brick........
[LG G8 Guides, News, & Discussion] Cryomichel:
Using the 1) section of this post, I managed to get back a Qualcom QDLoader again in my device manager

I amnot able to get download mode... When I connect the phone to USB hlding PWR+VolDown then clicking VOlUp, it appears as QDLoader 9008 (COM11) in device manager and I was able to access the partitions in QFIL but that's it.... I flashed back the OPA, OPB, SIDA,... partitions which was told to be erased in the tutorial but the phone did not boot to LG logo or to download mode again. I also flashed again boot_a & boot_b.

I flashed again all partitions of section using both partition manager and cmd line and I get "Image data corrupted!" when holding pwr+volume-

Any idea ? Maybe flashing all partitions one by one again using QFIL ?
[LG G8 Guides, News, & Discussion] Cryomichel:
UPDATE : flashed back every single partiton (except userdata) of the phone and it booted !

Gladly, I took a looooong time to manually backup every partiton last time I tinkered the phone.
[LG G8 Guides, News, & Discussion] pappakul:

Does anybody have or know where to find the lun files for g8s? Or can I use any of the existing files? Is there any way to get those files from a lg file or something?
[LG G8 Guides, News, & Discussion] daniu:
Hi

Managed to get something back on the display by copying over partitions extracted from a kdz file with qfil. Now I can get into bootloader and from there I can Boot into twrp - however I cannot install twrp and in twrp I cannot install anything (no twrp and no lineage - even I followed their instructions and could flash boot.img with fastboot)

My phone is g8s

Are there official stock roms in img or zip format?

Does that help me or what would?

Would highly appreciate help

Regards
[LG G8 Guides, News, & Discussion] daniu:
can someone help me with some questions concerning this. I think I am not able to find answers on XDA easily:

Most cummulates around the question: what do I need to do differently with a G8S instead of other G8-phones.

in the meantime I extracted GPT/LUN-files from 2 different KDZ files: latesrt and the one before that and they contain a different amount of files: the latest only has 5 files, the one before has 7 - my phone also has 7 - I guess it would be better to use the one with the same amount?

How to get the correct sectors? Will the one described here work for G8S as well or were do I get the numbers?

I would appreciate help a lot and promise to share my experience ...
[LG G8 Guides, News, & Discussion] daniu:
Hi,

just if anybody else is having the same issue: I could solve my problem by flashing some img files from a kdz file. My phone is booting now and of course I made a LUN and partition backup. So if anybody is looking for a backup of G8s I can provide it. Please feel free to contact me

regards

Daniel

[LG G8 Guides, News, & Discussion] Chaitanya More:
what to do now? i did load image of respective partition i have erase then saved it
[LG G8 Guides, News, & Discussion] netmsm:
Just for safety, although I highly recommend, create backup of modemst1, modemst2, fsg and ftm.
[LG G8 Guides, News, & Discussion] Chaitanya More:
there is no lun 6 is it gone its just 5 lun
[LG G8 Guides, News, & Discussion] netmsm:

does FH_Loader means Q-fil?
[LG G8 Guides, News, & Discussion] netmsm:
fh_loader is an application installed with qpst found in the bin folder and works with cmd commands.
[LG G8 Guides, News, & Discussion] blaze2051:
ah okay thanks man
[LG G8 Guides, News, & Discussion] blaze2051:
so i hard bricked my g820um i keep getting these errors, i cant euse qfil to restore because theres an error also. sahara protocl mapping header unreadable. I cant open parition manager cause the head info is unreadble and it wont open it. I have backup files but i need a why to flash them. i dont have a download mode because its a rapid bootloop. but i still have EDL access. I somehow managed to get into download mode but i dont think thats useful at this point. my battery is low and it doesnt charge will its in a rapid bootloop, and it doesnt charge in EDL mode either, But looks like it does charge will in download mode, so thats a good thing to know. So as this point i have sprint backed up files and kdz extacted files. If someone could help me to create or have a link to rawprogram0 and patch0 .xml i might be able to use qfil or find a way to get passed the sahara fail header error.
[LG G8 Guides, News, & Discussion] netmsm:
If you still have "download mode" it's not a hard brick case and can be repaired by this guide easily.
[LG G8 Guides, News, & Discussion] blaze2051:
thanks for the link but it wont let me crossflash because i cant gain access to partition manager to erase sid a and b and op a and b. wont let be go from spr_US to Open CA
[LG G8 Guides, News, & Discussion] netmsm:
You may crossflash using "chiperase" if and only if you have created backup of modemst1, modemst2, fsg and ftm.
[LG G8 Guides, News, & Discussion] blaze2051:
i dont have backup on those files. so how come i keep getting sahara error. is there another way to flash ? is there a why to flash backup files without qfil is modemst1 the same as modem_a?

can i use erasechip and then flash any kdz? what causes not being able to use qfil? is there a way to access fasboot and somehow flash the system_a and op_a?

can you provide me with rawprogram0.xml and patch0.xml or how to make one for the g8?
[LG G8 Guides, News, & Discussion] netmsm:
If you have root access it's possible to create backup of any partition under superuser privilege.

Another way to create backup is through TWRP then backup EFS.

The last one can be done via bootloader, but the bootloader must be unlocked.

I can't provide xml files, but you can search for and fix why you get sahara error, which is the best thing to do.
[LG G8 Guides, News, & Discussion] blaze2051:
(SOLVED)no access to recovery or fastboot, flashed via livedvd Bjoern Kerler
[LG G8 Guides, News, & Discussion] netmsm:
To me it means the phone had no problem in partition table and all the malfunctionings were related to the software, windows, drivers...
[LG G8 Guides, News, & Discussion] blaze2051:
maybe your right idk i have to try like reboot into edl like 5 times or more until it works idk why when flashing kdz does it have to be open CA 20J or can it be open US 20d? does it matter what kdz i try to use?
[LG G8 Guides, News, & Discussion] netmsm:
Maybe it's been because of usb cable or delaying to open partition manager after getting into EDL.

Use any KDZ.
[LG G8 Guides, News, & Discussion] blaze2051:
i solved my problem it was not a port or cable it was the version and it needed to be qfil from qpts 2.7.474 under windows 10 needed admin rights and comp. mode windows 8
[LG G8 Guides, News, & Discussion] blaze2051:
btw do you know if V50 roms are flashable on the G8? im looking for LOS 17.1 for my G820um
[LG G8 Guides, News, & Discussion] netmsm:
I don't think so! You can try the GSI version of it.
[LG G8 Guides, News, & Discussion] blaze2051:
you have link to gsi rom link or guide, i cant find A10 gsi rom
[LG G8 Guides, News, & Discussion] netmsm:

Please write in English so that I can reply.

It seems you have problem with OP partition (Google translate says).

Forget OP partition and just restore necessary partitions to get into "download mode". Then flash the phone with LGUP according to the tutorial here, the C part. For this you need requirements and do preparations suggested in that thread.

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://xdaforums.com/t/guide-lg-g8...nlock-and-magisk-root-using-firehose.4221793/

But this is where I am stuck at right now

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.

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?

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

There are some works and it takes much time. I can't make it on a virtual connection.

Anyway, just to give it a go, send me the PartitionsList.xml file which is generated by Qfil.
