Hi devs
I am an unfortunate soul as my recently purchased LGOG E975 just got bricked. The whole story goes like this -
I successfully rooted the phone one week ago and it was working fine until yesterday when I uninstalled the Google Play Movies app via Root Delete app. The problem started when I restarted the phone - it gave a "Security error" on boot and went into restart loop. Worried I searched at Xda forum for the solution and tried the "TeenyBins" method first (here http://forum.xda-developers.com/showthread.php?t=2249500). But it only aggravated the problem - at 85% of process the phone showed as disconnected from LGNPST and after trying many times the same problem persisted (the process never got to 100%). However the method installed TWRP custom recovery in the phone and a Google Logo replaced the LG logo at boot. Phone was normally booting in download mode and custom recovery but the recovery is unable to do anything - it shows as "Failed" whenever I try to wipe any cache, mount any partition, flash any custom ROM (which I pushed via adb) or take backup. Rather it shows "No OS installed" whenever I reboot, power off etc. TWRP is also showing no data inside sdcard via the inbuilt file manager. What is the problem?
Fed up, I tried LG Support tool - phone is successfully detected in "download mode" (everything is shown including the OS version which means OS is intact). I choose "phone recovery" option in LG support tool and it successfully downloaded the stock firmware (about 1.1 GB wait wait and wait) and when it tried to flash the phone it showed as the phone is not connected and instructed to unplug the phone and restart it and then again connect to PC. I followed everything carefully putting the phone in download mode again but again and again same error......Oh God for heavens sake....
Fed up, I then tried this method (http://forum.xda-developers.com/showthread.php?t=2010624) - downloaded the latest KDZ (>1GB) according to my phone from LG servers and used the KDZ FW Updater to flash the phone but the tool gave error "File extracted error" and I repeated the process again and again but no avail..............here I am, after 48 hours of desperation having a phone with the same **** Google logo on boot and the screen goes black...nothing happens thereafter..
Please forum devs, experts, moderators or any kind soul, I beg you to help me.... :crying:
If yu ve done the second method before instead of lgnpst tool there may b chances of helping yu.... And make sure which bin nd dll file yu flashed...??

OK One question.
Can you get into download mode? Flash MODE?
Follow this
1.Install all drivers LG
2.Download firmware from here http://www.lg-phones.org/official-stock-lg-optimus-g-firmware-rom.html
3.Download http://www.mediafire.com/download/sj5y073xal03ntw/KDZ_FW_UPD_EN.rar
4.Extract KDZ_FW_UPD on desktop
5.Install msxml.exe
6.When done run windows enabler. You will see the icon and left klick on it and choose ON
Now you should se ON at the ICON
7.When done start KDZ_FW_UPD.exe
8.Chose 3GQCT in TYPE and Phone Mode CS_Emergency
9.Then Turn of the Phone. Now hold Vol UP and Vol Down at same time. Hold and plug in the USB cable into your phone
Now you should be in DOWNLOAD mode
10.Now chose your firmware in KDZ File and press Launch Software Update
If it starts to flash dont interrupt it until you see PARAM 1 again. You phone will auto reboot at PAram 95 but dont discconect until you see PARAM 1 again.
If you get bootloop when restart give it 2 min. If it keeps show LG logo then turn of and do FACTORY RESET
Hold Vol up + Power at same TIME i think Now you should get Factory Reset MENU. Now press power again and it should work.
GOOD LUCK

Thanks for your time dear
but I have exactly followed the process you mentioned and unfortunately still got the KDZ extract error. I have downloaded KDZ for my phone from different locations multiple times but none of the KDZ worked with KDZ FW Updater. It looks like the current KDZ FW Updater is unable to handle the large KDZ files (>1GB) of newer phones while it works fine for older smaller KDZs. In this way this updater is a bit outdated. I request the developers to please update this wonderful tool to make it compatible with latest KDZs.
Try using kdz from romania,it has 982 mb and it's 10D.

But i flashed mine KDZ and its above 1GB and it extracted without issue. It must be something with your PC or something.
Mine extracted without issues
I think you have CORRUPT DOWNLOADS.
Do you unzip the KDZ file from the RAR? Or do you point KDZ Updater to the RAR file? You must unpack RAR so you file will be shown as E97510B_00.KDZ this is the Europe Open Version.
Remember if you unrar the file check if any errors coming when unpacking. If so then your RAR is corrupted and you need to redownload.
'did you RUN Updater as ADMIN?
Download this version of the KDZ European Open

It must WORK.

I have the .KDZ file and not .rar but I did not run the program as admin so will try again. It may be a corrupt download so will download again.
One question though, my phone is E97510E_00 (Indian version) so can I flash with the 10B open Europ. version KDZ you mentioned above?
Basically all firmwares are identical.the only differences are operator related. If you can find what are the 4g/lte frequencies of your operator,i could tell you what europe firmware to flash.if you don't have/want 4g,i guess you could flash the latest 10D european kdz without problems.

Mate just flash EU version so you can have working phone. If you sucess you can seek for answer later to flash indian ver.

exactly same problem!
hello my friend,
i have exactly the same problem as you with the same results.today ill try doing this in a desktop and see if the extract problem is gone...it drives me crazy.
please if yu fing something write it here...you ll save me!thank you!
p.s. i have f180 U+ edition
ok i found solution combining all of what i ve read..(and read a lot)
1)find a custom rom (i used avatar) but unzip it and go to \META-INF\com\google\android and open updater script with notepad.Delete this "(assert(getprop("ro.product.device") == "e975" || getprop("ro.build.product") == "e975");"
then save the file.
go to first folder that u unzipped and take MetaInf,boot img and system and put them in a new zip.
2)so since u have twrp in your telephone,push with adb the zip from step 1 inside the phone (how to push a rom here)
3)the phone will normally open when you reboot.if you dont have signal go here and download your phones modem.Copy it through your pc to your phone and then reboot again to recovery mode and install this file(do not unzip it)
clear cache,do a factory reset and in the next boot you ll be allright!

Hi,
Really excited, but can u please tell me the step by step procedure. My phone is a F180L korean Sim and i really dont know which is my actual make.. i mean like E973 or E975. I bought this phone to india and unfortunately its U+ sim locked and i was unable to use this phone in indian networks. Hence after going trough this forum, i learned how to change a firmware and how to convert this phone to E975 and i downloaded one for india from the official LG site and there were KDZ extraction error. i tried it with the LG PC sync method and its showing the memory is low and free up some space in the memory. but after downloading a firmware for Europe, i could update my phone into E975, but my indian sim is not getting connected. So i request everyone for a solution. I tried many things already and soft bricked many times.. luckily i could recover it using LG support.
SO KINDLY TELL US HOW U DID IT WITH THE AVATAR ROM AND WHAT DO U MEAN BY \META-INF\com\google\android.
Many thanks

so this is what i did.
1.use LGNPST prog with the small file for installing TWRP in your phone (see how here)
2.Download a custom ROM.I used this.The file will be in ZIP format/
3.copy your rom in a new folder.Rightclick on ROM and press extract here.The extracted files will be 2 folders (METAINF,SYSTEM) and boot.img.Open META-INF\com\google\android (these are folders) and there will be a file "updater script ".Right click on this file and select open with notepad.Then delete the following " (assert(getprop("ro.product.device") == "e975" || getprop("ro.build.product") == "e975"); ".Press ctrl+s to save the file.
4.Go to the starting folder,select again METAINF,SYSTEM and boot.img ,right click them and press add to archive(with winrar).In there give a name and be sure to select zi compression.So this new ZIP you've just created is the new ROM.
5.Now you have to send the ZIP you created to your phone.This can be done with ADB push.To read how to do it please read here
6.Once you transfer that file into phone you have to disconnect your phone and press vol+ button and then power on.This is FASTBOOT.Press 2 time the vol- button so it says RECOVERY MODE.Then press the power button and wait to open the TWRP menu.
7.Now that you are in TWRP select wipe and wipe dalvik,cache and do factory reset.Then go to install and youll see the pushed ZIP file that you transfered before.Click on this and press install.
8.After a while it will write that is done.Do a reboot and the new ROM will be fine.
9.If it opens and you dont have signal go to this site here and download the modem for your phone.Mine worked with Korean version modem.I dont know what you should install for Pakistan unfortunatelly.So when you download it,send it in your phone through usb connection (now your phone works,no need of ADB push) and then go to TWRP in recovery mode and install modem like the way you installed the ROM before.Wipe data again and do a factory reset and then your phone should be ok.
BTW you have to know that these ROMS have some bugs but you can do epic customization and the guys always update the rom over the air to do it more stable.
If you have any question feel free to make them!Good luck!

Thanks a Lot MafiaGR....
I didn't tried this yet as i did a different method and i am using it on trial basis. is it works.. then i am more than happy enough to continue... let me explain what i did.. I have rooted my F180L korean U+ sim unlocked phone with motochopper. After rooting the same, then i unlocked my bootlocker with freegee-beta (many thanks to Shell). Then i downloaded a kdz file (E97510D_00.kdz , Europe Open) from the LG server. then i updated the same by putting my phone in download mode (volume up+volume down + USB connected + power ON) and updated with KDZ updated program.. after quite some time my phone got rebooted with E975 Europe Open firmware. Even after this i was unable to get indian network in the phone. So Using Rom manager, i downloaded CyanogenMod 10.1 Rom with GApps and flashed my ROM again. Now my phone is getting connected with indian network. but the problem i am facing is with my network not getting registered... i can find about 12 networks in my phone but unable to register into any of them...Need help from u guys...
Thanks in advance

Finally I got the problem solved and my phone back !!
Unfortunately nothing worked for me as suggested by you, guys may be I was doing something wrong or else.
Finally I decided to contact LG Service Center in my city and after initial try they told me that "the phone is not getting connected in flashing mode" and I had to submit the phone to them. Next day they called me and told that there is a hardware problem and a "part/PCB" will be replaced within next 7 days. And today they called me again with the good news - your phone has been repaired and I can pick it up anytime. Elated I got the phone within an hour, live and kicking. Thank God I got my loving phone back and most importantly they did not detected that the phone was rooted and thus out of warranty. Lucky me!!! :laugh:
Any way thanks everyone for your prompt help....:good:

maybe you hae to try diferent modems for the mobile phone until you find the right one.Mine works with the Korean modem although i live in Greece.You may have to find exactly in what frquency your provider works and then see where in the world a provider has exasctly the same frequency as yours,and then download the modem drivers from the LGOGs that work in this country.
Hope it works!

well this is the best choice,even if they say that if you root your mobile phone,you lose the guarantee.But its a bit difficult for me to do that since i ordered the mobile phone from Chine and i live in Greece!So i should give away my phone a long time to get fixed and i cant wait!XD

You are absolutely correct. The problem for me was with the Modem for sure. I flashed with a Nexus 4 modem in my phone and i could register network in my phone. but the problem now is that the signal is very weak. I tried flashing many modems like E970 Att, then E973 Tellus and few more.. but i couldnt get a better signal. if the signal is good, then the sim is not getting registered. i tried to search for an indian modem for E975 which i couldnt find.. moreover i am unable to download the indian/thailand/hongkong firmwares from LG official site as its saying that the Access is denied. Please help me with those links as i am really desperate to use my phone...
Thanks again

Hi,
My LG G3 died during the night when a firmware update started and the battery was low.
Now the phone isn't booting. It gets stuck at the LG logo.
I can put the phone into download mode but not much else. It it's recognized by any PC I've plugged it into.
The main issue here is that I need to recover some very important data that hasn't been backed up (ye I know stupid). I've searched and searched but all I get are some iffy maybes mostly regarding some Samsung phones so.
You can try a using a linux os on pc sometime it can still pick up ure drives
Thanks I'll try.
Unfortunately I don't use Linux or know anyone that does outside of work so it will take a while.
In the meantime if anyone else has suggestions I'm all ears!
Now r u rooted with twrp
The phone is 100% stock
Just flash stock kdz in a normal mode not cse flash but you have to select exact firmware you had ....so you dont loose any data...hope it helps

How would I even know what exact firmware I had?
The phone actually booted up when started into download mode and gave the 'firmware update' screen but just stuck at 0%
Ok...try to flash what firmaware version you had before software update....i think ota not installed properly...if it doesn't work try to flash latest firmware for your phone...means which version coming as ota for your phone....also remember for the first time it's should be take some time to start.if both not working you have to do a cse flash ?...but if you sacrifice your data....factory reset is a simple option....you don't have flash anything just search in forum how to hard reset and your problem solve,think so ?
Hello, (complete n00b here)
Several days ago I've tried to flash a 6.0 MM (from 5.1) to my LG G4 H815 phone. There was no option to do it automatically so I proceded to do it manually via flashboot.
I hard-bricked it to oblivion as in black screen, no response whatsoever.
While investigating @ the internet I've managed to understand I could get it fixed via quadcomm drivers (mode 9008).
Tried various "fixes" for H815 but was getting safari download errors. For some reason I tried a LS991 fix and it worked. When I started the phone it showed no logo but just a secure booting error 1006.
Still, could enter firmware download so I began to flash a lot of KDZ firmwares with no success.
LGUP shows my model : H81510H.
While in fastboot mode there is a note below (wasn't there the first time) with codes : 633 B46 or something like that.
While flashing anything it ALWAYS STOPS at 9% with a tot anti-rollback error. While flashing the code changes briefly where one can read smth like : LGLS991ZVA ver. 6.0
Managed to download some KDZ for that exact model, SAME ERROR. Tried to find / flash LS991ZVA with no success in finding a TOT file.
Also, managed to get ADB drivers up and it shows unauthorized in listing (LS991). Fastboot does not detect my device even in fastboot mode @ phone.
Please HELP!

H81510h is os version it is still at 5.1 I think....what may help is plug your phone in with lgup and drop the battery out of it then closes of LG up put battery back in and start LG up and find kdz that matchs your phone and make sure that it doesn't have anti rollback.....

Hello and thx for reply. I tried to do what u've said. It did something (I was looking for a while back). When I plug the cable back in, my windows 7 immediately installs quadcomm hs-usb driver (9008) and my phone acts as if it was dead. LGUP cannot find it in that state. I've been trying to QFIL the "proper" soft but it continues to pop different errors (using different QFIL versions). Either saharafail or some sort of download fail.
LGUP still presents an error (if I decide to "fastboot" it) @ 9% 0x2000, TOT antirollback version is smaller than device version.
How can I make sure I've got the proper KDZ without ANTI-ROLLBACK?

Thx again. Uppercut shows H81510H as LGUP did. Is it possible that it's somehow write-protected?
It confuses me, since during the firmware update on my phone, I get this small box below the picture showing wierd codes : 633A Bxx and when I'm trying to flash my phone, the code gets longer with LS991ZVA v6.0 and more other. It then stops.
Funny thing is, when I got the phone I couldn't even connect to the LG bridge to update it at all. I've managed to do it bugging the MTP protocol but THAT on the other hand prevented me from copying stuff / FLASH my phone to MM 6.0. Had to factory reset it back then and all went back to "normal" = LG couldnt detect my device but I could copy photos or stuff from it.
NOW, when my phone is bricked, LGbridge DETECTS my phone (in fastboot), downloads the newest KDZ update BUT cannot install it (same thing as in LGUP). Hence my question : is it somehow write-protected?

Have you tried to eset it by pushing power and volume own then when you see bootsplash then release power button and hen quickly push the power button again....
But in your case push power and volume down within the count or 20 then release power then push power button again and see what happens and then try the same thing on volume up......
Thanks for the reply.
I did what u've said. Despite no logo I tried to release power button for a second just after the screen's brightness goes up (I also get a small vibration @ start). Everytime I get secure booting error 1006 after a few seconds.
On the other hand when I did that with volume UP button there was no error but there was nothing aswell until I release power button in which case I got the secure booting error. All of the above tries were done with no USB connection with anything.

Do try with usb s well it may do something r do nothing......
Can't tell atm since I gave it to professionals. I'll wait and see how it'll turn up. Thx for all the effort tho, was nice to tinker with a lil help
@Longbranch did you solve this problem ? I'm in the same state but my phone model is H810, everything else is the same as yours.
Nope, not really. I gave it back to the reseller and my money got returned luckily.
The professionals I refer to above did install a specific firmware for the ls991 type. Firmware ZVB I think. The only one appliable apparently. Anyways, as I suspected the ls991 type is for the US and therefore it didn't work in my country in EU. My sim card wouldnt work with it. Besides, without the sim card, the phone decided to freeze and die after several minutes every time I turn it on. Swapped for LG G5 and it's working flawlessly up until this day.
good for you, what i don't understand is that it's a h810 model but now identify as ls991 does that mean you can convert it just by a Qfil flash? I may try another model flash if can't find a suitable Rom for it

Yes! That's what I and neutrondev telling everyone :
do not use qfil without the knowledge about the result!
The only working firehose file available out there is for the ls991 and that means if you use it it will turn your device into a ls991 without any way to get back to your previous device model!!

@steadfasterX since I have done it already is there any way to get it working even as an LS991 ?
here is what i did till now
the reason for using Qfill is that it went dead after flashing an H810 rom .
after that when it's in download mode it doesn't allow me to flash the ls911ZV5 ls911ZV6 ls911ZV6_12 roms that i found ( it says LS991ZVA )
so i went in fastboot and flashed boot/aboot/recovery....img extracted from the ls911ZV6 rom then it accepted the rom in download mode
but it is stuck in a hard bootloop ( reboots when it is getting in recovery but still has download mode yet no fastboot as before)
any thoughts ?

Yes it's possible. You can boot a h811 H815 or any other rom you like. Even LOS!!
Great right? BUT you are bounded to the ls991 modem and so you need to be in a sprint network to use telephony. That means the phone is now useless outside the US .
And you wrote you tried ls911 ROMs? I hope you meant ls991
I work on a fully working experience on every network though. Checkout my proof of concept for unlocking the bootloader thread
I can go into details on IRC if you like.

@steadfasterX thank you for keeping up with me ! ( btw what room on IRC ?)
for now I have used Qfill again and got fastboot working again and flashed TWRP ( not sure where ! ) so when the phone is off and i plug the usb it boots to twrp ( but it doesn't in recovery )
normal boot will show "secure boot error 1002"
then i flashed twrp img to recovery partition using twrp but it didn't work in recovery ( still reboots after showing Recovery Mode loading screen )
also tried to load some roms on the device to try them but I got error "file too large for filesystem " when copying them .
atm I don't know the state I'm in and what should be next ?
btw here are the recovery log and dmesg

Np we can bring you back to life but as already said without cell service. That's the price for the firehose and unlocked feeling you have now.
Did you found and read my thread here?

Hi, recently decided to reset my phone back to stock as I had some trouble with a few programs after resetting my phone. I tried factory reset but the programs didn't work so I decided I would try to just restore to stock and start fresh. I followed a guide on how to do the stock restore using LGUP/LG Flash Tool. I followed the guide and put the KDZ File into the program and pressed cse flash. The program worked till around 12% then it got stuck and just didn't work anymore. It said error so I kept trying over and over as some guides on this problem said to keep trying.
Nothing has happened and my phone is now stuck on firmware update screen. I have taken the battery out multiple times and replaced it back in and turned the phone on but it automatically goes to that screen after showing the lg logo. I have tried the volume down and power button factory reset but that doesn't work and tried getting onto download screen if that was any help but couldn't do that either. Now I'm stuck here... Any help? Don't have any other phone and can't afford to get a new one so I would like to try fix this anyway possible.
After failing the flash update thing the program says failed my phone says 0%. It went to 1% once and then just went back to 0% after it didn't work. So don't know if it's been changed in anyway. All help appreciated.

I did refurbish first as I wanted to start new and it didn't work even though I did it a few times. I tried upgrade after and still nothing. Also have tried Uppercut and that does the same as normal LGUP.
The furthest % it got to was 19 on the computer and 8 on the phone and then it just stopped again. It usually stays between 11-19%. But most of the time 11%-16%
Have you made sure that it is the right region......
Try to down load just tot file and try that....

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.

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.

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
