more info is better than none, what did you do to "accidentally brick" your phone? and if you are stuck in download mode you could try the lg mobile support tool and re load the rom for your device.

READ completely, including the link in 4 before starting!!!
download the tool using the lg d851, under t-mobile. the tool is generic, and can be found at lg.com under support/downloads
1. install LG Mobile Support Tool
2. run Tool, it will query lg for updates and do so if needed.
3. Install USB Driver (dismiss if you have done so already)
4. follow this process: http://forum.xda-developers.com/showpost.php?p=51268802&postcount=21 (use 5. below to put into download mode, not vol up and down like the link states)
5. with your device off, hold the volume up button while plugging in your USB cable with the Tool open.
6 you system will recognize the device and configure drivers, this will take a minute.
7. continue following the link in 4.
I ran into the same problem and now i'm stuck in downloadmode!
Does this method work? Or is there any other fix yet?
Thanks in advance!

hey guys, don't ask for a different fix if you don't bother to explain how your phone got stuck in download mode. as for does this work? Why don't you try, it's the same tool used to upgrade firmwares instead of using OTA, and the link included shows how to get the tool to download the file (if it sees the same/current f/w it does not download the firmware) and you have nothing to loose, and this method is often used to recover from "soft bricking" your phone.
i was restoring my LG G3 to stock through the lg flash tool .....when i got through with it and restore was succesfull. somehow i forget the usb cable plugged through my pc usb port ...then connected my lg g4 that is where the flash tool got my Lg g4 on Downloade mode ....i tried all the methodes somehow i think the recovery is messed up .....i can get to the recovery through the button but it reboot straight to the download mode ....thanks every one for their support

don't think it's out yet, however my statement was somewhat incoherent. I meant to say if he had the kdz, he could use the flash tool to recover his phone.

Yea, at this point there no way to fix this without a kdz that I know of.
Call LG and tell them you need the kdz to restore your G4.
i was lucky, i had flashed twrp before my phone soft brick..

I got an LG G4 which is stuck on lg screen. When I put it in download mode, it shows download mode for a few seconds and restarts. I was trying to flash ZVB over ZVD and it ended up like this. Model is ls991 . Any help would be really appreciated!
Anyone got any idea? The whole thing started with getting rid of the Genisys rom ... I did not like it ... I thought I was going to bring it back to the stock, but then LG Up wrote an unkown device ... I thought it was flash with lg bridge ... that's what I lost. .. has removed recovery and has stopped updating at 16% ... since then it is only download mode I tried to update but failed with all three programs ... LG up to start - unkown device, LG bridge stop at 16% , LG Falsh Tool 9% ... sorry for my english
Hi guys I'm a newbie here and this is my first time posting.
I was trying to flash stock on my LG G3 but I made a really really stupid mistake. I used the flashtool found over here at http://forum.xda-developers.com/showthread.php?t=2799647 but I had used the wrong tot file. Now my phone is stuck in download mode. I don't think my phone is hard bricked because it still boots up but only to the download mode no matter what I press. I also can't access my custom recovery now. I have tried flashing with kdz file for my phone using the LG Flash tool 2014 but on the LG Mobile Support Tool the progress bar goes up to 10/11% during the s/w update and I get an error after waiting for half an hour and the progress bar on my phone's firmware update screen only goes up by 2% at most. I can't find the tot file for my phone version to flash with so I'm stuck here. Help please?
phone version : v20g-sea-xx

hi , i have the same problem.
Did you try to flash the correct .tot file again?
Check the logs for the error which is generated from LG flash tool 2014.
May be you have cross D/L error due to wrong tot file flash.
I just bricked my g4 by flashing a kdz but then the kdz fdailed and after rebooting the phone it was only able and was immediately going ( after the lg logo) to the download mode/ firmware upgrade. It was not recognizable by LGUP. I added some dll files to help fix that LGUP issue but i dont know if its working because by g4 cannot be detected by LGUP. Going in recovery to factory reset and selecting Yes 2 times only freezes the phone.

I have exactly the same problem. I can flash v20p KDZ, but reboot still failed (stuck at LG logo).
Then I enter download mode, I can flash v29a tot polish nougat rom , but reboot still failed.
I notice that the LED is not flashing at LG logo screen.
Is there any other way to try?

You're sure that you wait long enough? You check how the process is running on the phone "flash status bar" while flashing in download mode screen?
You try to boot on recovery and factory reset?
I waited for 5 minutes.
The flash process completed 100% successfully.
I tried to boot in recovery and confirm ‘yes’ twice, but nothing happen.
If I flash android 5.1 and flash LG’s MSM big core disable tool tot, it can boot successfully.
So I guess my main board may have problem.
Now I need to see if there is an DIY way to fix this.

The only kdz file that worked for me to go back to MM 6.0 is H81520p_00_0314.kdz and i have tested alot of kdz and tot files too. Only this one kdz worked. I did a little Tutorial how to go back with this kdz, see on Page 16 .....22

This is the dll file i´ve just extraced from the H81520p kdz.
But this dll is normaly only needed when you get Errors in LGUP while flashing or flashing stuck on 11% or 22% etc.

I´m sure this wont help you out, but try it. Please point to the Refurbish tab in LGUP, the Upgrade won´t work.
My other Idea is to crash the Phone totaly, delete all Partions via TWRP and restore them to a working System.

Hi Everyone.
I'm in a big mess.
My LG G4 showed as H815 in device information (But it was F500L) . It had 5.1 (LP).
To update it to 7.0 (N) I flashed the TOT file for N with version H815 thru LG UP.
Now it did complete to 100%. The phone rebooted and showed error like " Central App not loded" or something like this.
I tried again to Flash the TOT file thru LG Up. It went till 21% then shoed error command not recognized.
I triedLG bridge. It shows device as F500L.
Although LG Bridge says update available, it could not update either.
So the problem is I flashed wrong version. My phone is F500L and its showing "firmware update" when plugged into USB with PC.
In LG Up it shows as H81510H
Please guide friends....

Why u flashed the tot file?
For your Location (Korea ? ) there is an official Update to 7....
Look here: https://lg-firmwares.com/lg-f500l-firmwares/
or this Link: https://lg-kdz-firmware.com/
You should use LGUP again and flash back with stock 5.1 or 6.0 kdz, follow the link.
Hope will helps you otherwise reply

Okay, that Sounds good Yes really..
I think the Probelm is in LGUP´s dll, you must replace the LGUP_8994.dll with the L500F kdz from.
Download the Tool LG Firmware extract, Link from my GDrive:
https://drive.google.com/file/d/1NTzwI-qLBpIgTov5PC4THZJWbAOhJDO3/view?usp=sharing
Start the tool and load the kdz in, then you see some files in the tool. Mark the lgup8994.dll and extract it, close the tool.
The dll can find now in the Folder of LG Firmware extract tool, rename it to LGUP_8994.dll
Copy that new dll and put into C:\Program Files\LG Electronics\LGUP\model\8994
The old LGUP_8994.dll remove to desktop and put the new dll in here and start again with LGUP.
Please point LGUP to Refurbish and NOT to Upgrade. The old dll that was in the Folder is for the Nougat tot file and the H81520p kdz only.
Hopefully thats will works for you, normaly it should !

Well this is not working.
LG UP recognizes my phone as H81529a. So it doesn;t let me flash F500L rom.
When I extracted 3994 DLL from F500L KDZ and replace in LGUP folder and start LG UP. It shouts wrong version DLL.
Is there any way I can make LG UP to recognize my device as F500L and Not H81529a.
LG Bridge recognizes it as F500L though but it doesn't update my phone either.
Please help n guide

Hmmmmmm
Okay, the H81529a Header says LGUP that is a G4 H815 with Anroid 7 ( 29a) on it. Okay, the LGUP_3994.dll wont work for your F500L kdz. By the Way..wich kdz you try to flash? is it a MM one or the Korean Nougat ?
On my H815 i had the 29a after flashing the Nougat tot file too and came back to MM ONLY with H81520p_00_0314.kdz other kdz for my H815 did fail too.
This Problem with LGUP is only the dll file...so you must find a working dll for LGUP.
Maybe you download the Korean Nougat kdz and extract the dll like the last posting before and flash the Korean Nougat, i think the Korean Nougat has 29a too, so LGUP should work.....
Or find a F500L20p kdz file...
I don´t know what to do yet. Sorry.

Well...
I have been able to sucessfully flash H81520p_00_0314.kdz on it.
It starts but no signal / network.
I'm from India so I think the version I flashed doesn't match with Indian Band.
Now what to do ?
In India following works :
2G network GSM 850 / 900 / 1800 / 1900 MHz
3G network HSDPA 850 / 900 / 1900 / 2100|TD-SCDMA

For my undstanding....
1) You have still H81520p_00_0314.kdz running on your Phone ? but no Indian Band ?
2) What Header is LGUP showing now?
If you have H81520p_00_0314.kdz on it, you are able to Downgrade to ever Version you want, H81520p_00_0314.kdz make it possible only !
So, find out your Rom for your Location and flash it with LGUP. Keep the 8994 dll it comes from H81520p_00_0314.kdz in the folder and flash.
After downgrade with LGUP (Refurbish Mod ) do a Over the Air update on your Phone or via LG Bridge and do "correct update Error" instead of "Search for Updates" and normaly its works.
Follow this Links for the Roms

If you are unsure what rom you must get, go to https://lg-firmware-rom.com/
and type your IMEI in and watch for the results.

Well
Problems just dont seem to end.
I hooked it up with LG bridge.
It showed model as "G4".
No version no code just G4.
I started to update it (thats before I read your msg)
Update stopped in between and phone turned off. I unplugged it and pulled out the battery. Restarted.
It showed LG logo and agained turned off.
I tried to reset by pressing Down vol n power button.
Options came to reset n I reset it.
Now again turned on. It showed optimizing android.
Stopped at 4 of 32 app and screen went blank.
Now LG bridge reads it as L500F at place of G4.
Hooked up again in download mode and LG UP disnt recognize it. Again restarted.
LG up recognized as H81520p.
I reflashed thr H815 20 p kdz.
Completed successfully.
But the problem is again same. It shows optimizing android and screen goes blank after 3 of 32 app or 4 of 32 app.
Have I messed up the recovery ?
I am able to go into download mode and LG up reads it as H81520p.

I will do my Best my Friend.
I don't understand why the optimizing Process stops....
Maybe there is something blocking the process.
My only idea now is to flash Twrp on it and wipe all chaches. Davlik,Data and Cache and let the phone boot up and see what is going on. This is the working TWRP for G4 on H81520p
https://drive.google.com/file/d/1sOsVDs1vZzuvirWQ0ByFPZv9BC9Eu4yH/view?usp=sharing
But for twrp flashing the Bootloader must be unlocked. You can do this on lg developer page ( https://developer.lge.com/resource/mobile/RetrieveBootloader.dev ), type in your IMEI and you get a unlock.bin via email.
I think you know the process for Bootloader unlocking otherwise i will guide you.

My only idea now is to flash Twrp on it and wipe all chaches. Davlik,Data and Cache and let the phone boot up and see what is going on.
But for twrp flashing the Bootloader must be unlocked. You can do this on lg developer page, type in your IMEI and you get a unlock.bin via email.
I think you know the process for Bootloader unlocking otherwise i will guide you.

Hi
Can bootloader be unlocked in LG G4 MM ?
Initially when i flashed nougat TOT on it, the firmaware update page was either in korean or chinese then after nougat TOT flash ot became in english.
Could it be that the recovery is also overwritten ?
Plz point me to bootloader unlock for it.
Many thanks from India

Hey.
Yes you can unlock Bootloader in MM too.
After the bootloader is unlocked, the Phone will reboot and do a Hardreset itself, you can´t do anything to block the Hardreset.
Notice: After flashing in any Versions the Recovery will be deleted too !! Example, if you have TWRP on the Phone and flashing any kind of firmware, the Recovery with TWRP in it will be deleting..thats normal in the flashing process.
BUT you CAN´T unlock the Bootloader yet ! You must enable the Developer Mod in the Phone first and set OEM unlock.
Your Phone does not boot up correctly at this moment, this Problem MUST be solved first !!
Did you try a Hardreset ?
Switch Phone off, pull Battery and place it back. Press the Volume down Button and keep hold and press Power Button and keep pressed, after LG Logo is showing up, release the Power Button for 1 secound but still keep Volume down pressed. Press Powerbutton again and hold pressed until the Green Android thing is showing up, release both buttons now.
In short: After Battery was pulled and replaced..
Press and hold VOL -
Press and hold Power
after LG Logo is showing up
Release Power 1 Sec. and press again and hold until Android puppy is showing, release both Buttons.
Now the Phone should boot up and do the optimazion process correctly.
If not, then i have no more ideas. Maybe flash a MM 5.0 Version over the MM 6.0 via REFURBISH option in LGUP
Hopefully something works for you.

SO Finally it's dead.
I tried to hard reset and the puppy appeared and then it rebooted. Again went to optimizing apps. Stuck at 14 of 32.
Became unresponsive.
I pulled out the battery and reinserting after 20 sec.
Nothing.
After several battery removal and reinserts, I managed to get it in download mode.
I was trying to Flash H815 20p KDZ again as it was working initially. But at 50% process of flashing, it shows error of USB Disconnected and phone screen went blank.
Since then it was neither starting nor getting in download mode. Tried everything.
It doesn't even show after connecting to PC.
Dead as dodo.
I looked at it with more attention. Removed the battery cover saw the model on mobile body,
it has model no H811
On box the model no is H815
LG Bridge recognized it as F500L.
IMEI No search says its F500L.
So basically it looks to either a refurbished phone or a fake.
I bought it thru eBay on 18th Jan 18. So I had to claim refund against a faulty product.
I suppose I'll get a refund, I will skip replacement as it's likely that the seller might again push a refurbished / fake phone.
End of the story till then.
If I dont get a refund I'll revive the thread.
Thanks to FOTO AG and XDA for support n advice.

You should have hexedited a F500L tot(wich is your motherboard version) and changed the LGX to H815, saved the file and then flashed. That could been solved your issue and turned your phone back to F500 with a functional and booting system
