Guys, This fix is exactly what OP says "100%"!!! i say this because i bricked my phone again (on purpose this time) just to check consistency of the fix and im back from the dead once again. Feels like my phone is immortal now! lol....:)

Try flashing h811 20o kdz.

---------- Post added at 01:53 PM ---------- Previous post was at 01:15 PM ----------

Hey guys, This is step by step how i got this to work more than once for my H811. This is provided you have successfully written singleimage.bin to sdcard and can get into the twrp that is installed to sdcard by singleimage.bin.

1.Find and download H811 20i debloated+rooted.zip ROM and H811 20o KDZ.

2.Boot phone to twrp and flash the H811 20i debloated+rooted.zip ROM

3.Reboot and go through setup process normally so you can get to settings to enable OEM UNLOCK and USB DEBUGGING

4.Plug phone to PC and run LGUP as admin

5.Choose update and locate H811 20o KDZ and select it

6.CLOSE LGUP

7.Reopen LGUP and H811 20o KDZ should still be selected and it should be on REFURBISH(DONT CHANGE ANYTHING)

8.Start flash process

9.Once your phone reboots to download mode remove sdcard and let flash finish.

10.Phone should reboot without sdcard.

That is my whole process and i did this again (as i posted) and again and it works everytime. So i hope this helps because

i know how messed up it is to have a hard bricked phone. Good Luck Guys!!!

[T-Mobile LG G4] kenerly:
I tried to flash it again, this time I did it on my laptop using the same steps.... It worked, go figure...:confused:
[T-Mobile LG G4] jam1445:
Bro, the reason is, i find this problem in many refurb phones. They show one model in about page and on phones back but once you check the model in stock recovery, it shows another model.

As your phone is already dead. You should try to use Dump File for H811. If it does not work, then we can go for VS986. I hope it will help you. Most of the times the dump file works for most of the variants just to get to download mode.
[T-Mobile LG G4] T.E.I.M:
:confused:

hi jam1445

i treid the H811 dump file by 32GB SD Card (i havnt 64 GB) ...does nt work

for that i want to try VS986 dump

friends I need your help, my phone enters download mode , but only displays as two seconds then restart and displays the logo of LG and just stays restarting , I need your help. !
[T-Mobile LG G4] drimtea:
Hi guys!

So nice to meet you! Thank you very much for this solution! Bought a phone a week ago (JG G4 H811), and it was hardbricked. But I used a lot of methods and now I am here, the phone is alive, but I am still unable to make it work properly. LG UP says that it is unknown model, and in the Settings/Hardware info/Model number says it is LG-H815... But still it is signed as H811 on the back.

I think the previous user failed to make it work in Russia, and I am also unable due to LGUP's "unknown model".

Please, help to make it work at least as a camera (I could use wi-fi, but camera is not working at all), I can‘t make my notebook to recognize it!
[T-Mobile LG G4] divine1250:
LGUP doesnt recognize your device because your device is mismatched. The h815 firmware on your device does not belong there so LGUP will display your device as unknown. You need to get into twrp and find/flash h811 20i stock rooted rom zip. Then LGUP will display correct model number. Try it, Worked for me with the dead G4 i purchased from ebay.
[T-Mobile LG G4] split69:
Hi Everyone,

Thank you. This solution is such a miracle but I have an H810 AT&T phone. Will this work for me ?

Thank you,

[T-Mobile LG G4] usyusy:
will it work for H815 ?
[T-Mobile LG G4] jam1445:
You can try
[T-Mobile LG G4] jam1445:
Sorry to say but no solution. It is bootloop issue which can only be repaired by changing motherboard
[T-Mobile LG G4] rokaxis:
H815 dump does not work in h818p, try this link, and after several attempts but recognizing worked as H815, I need to h818p, any idea
[T-Mobile LG G4] split69:
Thanks. but do you know by any chance where I can get the appropriate system image bin file ? I couldn't get a hold of it.
[T-Mobile LG G4] cranknet:
Is it necessary to format the memory card to Exfat format? because I didn't do that, May be this is why my phone didn't work!
[T-Mobile LG G4] jam1445:
Bro i may be able to make it but cannot as i do not have access to that variant. I will try my best to get it asap.
[T-Mobile LG G4] jam1445:
Bro each step is necessary. If you missed any single step, it will not work.
[T-Mobile LG G4] split69:
Thanks a bunch jam1445. I will look forward to it. :good:
[T-Mobile LG G4] cranknet:
Damn, I tried this method several times with my G Flex2 but it didn't work, May be because I didn't format it as Exfat ...:confused:

[T-Mobile LG G4] greedness:
To those looking for the VS986 image, I have one. It was extracted from a rooted 13b. I dont know if he had TWRP or not. I tried testing it, but I couldnt get it to work. It would just corrupt the SD card, unlike with the image files in here where it would create an image folder with a bunch of partition files inside. But anyway, if anyone would like to give it a shot yourself, let me know.
[T-Mobile LG G4] T.E.I.M:
let try how...give me link ....?
[T-Mobile LG G4] deanpaul.lt:

Thank you for this guide.

It revived my dead phone back to life.

It had been dead for almost 3 months now with no soution.

I had it only for 2 months or so before it got bricked due to my noobiness.

Thanks once again.
[T-Mobile LG G4] greedness:
I couldnt get it to work myself, and the other guy hasnt responded yet.
[T-Mobile LG G4] T.E.I.M:

Phone goes to download mode after flashing bin file but phone keep rebooting after 2 sec due to which i cannot flash the stock rom any solution?? and i also want to ask is there any bootloader file in systemimage.bin??
[T-Mobile LG G4] divine1250:
Everyone going through lgup error when reaching 9%:

You must start flashing from within rom itself(not download mode). 9% is when lgup expects to automatically reboot you to download mode to complete flash. But if you are already in download mode i think it confuses lgup which results in error and reboot. I went through this until i went into recovery and flashed stock rooted 20i zip and setup as normal. Everything booted fine except i couldnt boot device without sdcard inserted. Thats when i decided to try lgup the normal way. As soon as it reached 9% it automatically rebooted my phone to download mode(at which point i removed sdcard)and the flash completed without error and rebooted without sdcard. Hope this helps everyone having problems.
[T-Mobile LG G4] Malik0999:
i have downloaded the kdz file you provided but LGup asks for tot file, what to do now?
[T-Mobile LG G4] mihelius:
manually change tot extension to kdz in LGUP tool and add firmware asis.

It was brick hard h815 device model can be corrected with the same method did you? Can you give kdz and direct link to the file system, if any?

If there are errors in spelling sorry I used google translation.
[T-Mobile LG G4] abatoir:
Hey guys I'm in the process of trying to get my vs986 back to life using this same method, presently I have not found any system.img for this model. So I'm trying 2 options,1 there is a rooted system.img on XDA it's for v13B. I have downloaded it and I'm presently extracting it. 2 I've downloaded kdz v26a and I'm using the lg extractor to extract the system.bin(also presently extracting) so hopefully I'll see which one works for this model, thanks for the wicked resurrection tut @ OP
[T-Mobile LG G4] T.E.I.M:
keep us on your news

....:)
[T-Mobile LG G4] abatoir:
Well so far it's been unsuccessful, both files didn't work. But I'm still trying, also one thing that's kinda weird: my device comes on when it feels like it(without system.img on an SD card) ,when it don't come on it is detected as qdloader , most times when I try to go into download mode it either freezes on downloading and then go into qdloader mode or it just goes straight into qdloader, any

---------- Post added at 04:39 PM ---------- Previous post was at 04:19 PM ----------

Ok so just something to add to my findings, I have downloaded the singleimage file posted by OP, it's way different from the image files that I have extracted, after writing the image to my SD card I can actually open it up in file explorer. However when I'm finished writing my system.img file explorer ask for reformatting, so I guess the rightful owner of the the h811 singleimage file can enlighten us on the process of how to obtain such a file. It's also way smaller than my img files
[T-Mobile LG G4] greedness:
How did you brick yours? By downgrading to 11a?
[T-Mobile LG G4] abatoir:
Truth is the device ain't mine. Just trying to fix it for this guy. He decided to take it away, so Im off the case, if someone would provide a dump from their device, I'm sure it will work
[T-Mobile LG G4] T.E.I.M:
give us this dump

..lets we try
[T-Mobile LG G4] greedness:
Its probably not hard bricked then. Cause if it was, theres no way it would 'boot up sometimes'.
[T-Mobile LG G4] tavocabe:
Guys what if I can't even get it to boot in download mode or any mode? Using singleimage.bin or EMMC_ROM1_032G74_1803230737_00000000_20000000.bin from another thread but the phone won't show any signs of life. I'm trying with a 2GB Microsd maybe that's why? Both images files are way less than 1GB so I don't know why this should matters.

EDIT: I'm not getting any kind of response from my PC either
[T-Mobile LG G4] waylo:
No response from the PC indicates more that the phone is dead. Has it been charged?

The PC should pick up on an attached phone if it's suffering from a bad firmware flash. Anything more damaging, such as hardware failure, it may not.
[T-Mobile LG G4] tavocabe:
I just bought it and the guy told me it's been around 3 days since it started bootlooping and they put it off the charger, but I checked the battery voltage and it gives around 4V so should it be enough?
[T-Mobile LG G4] greedness:
You need at least 8GB as far as I know, because the files are partition tables, and what it does is it creates different partitions with different size allocations totaling to about 8GB.

It worked for me!

I had an issue with cyanogenmod and cell and data signal, so I decided to flash the modem provided by LG going through the XDA LG G4 cyanogenmod forum for T-mobile. Couldn't even wipe completely and flash new Cyanogenmod rom after that. Then I decided to flash the stock LG rom through TWRP and after a successful flash I rebooted with it charging. Then totally forgot about it and came to check and discover it wouldn't turn on. The same no lights no response no matter what I tried. With your method I was able to get a sign of life "0% charge before turn on" I waited for hours to charge but it kept at zero. Maybe my battery is fried. Luckily I had a extended battery and was able to complete your process without a hiccup!

Thanks!!

Hello everyone

I know this is a thread to unbrick (T-Mobile) LG G4 H811 9008 Qualcomm, but I have a (sprint) LG G4 LS991 brick with 9008 Qualcomm, I think this metod could work for my phone but not sure of what files do I need to try, so if anyone have an idea let me know.

Всё что удалось сделать, это запустить смартфон и увидеть bootlogo. Прошивка записывалась программой eMMC RAW Tool из распакованного TOT файла.

То что у одних получается восстановить через sd карту, а у других нет, объясняется тем, что многие уже обновили прошивку до последней версии, и этот дамп уже к ним не подходит, нужен новый.
