D855 MM Stuck at TWRP after flashing KDZ with LGUP

I dont understand why this happens because i follow the rules exactly.
I was using MM with TWRP+Root.(Not kingroot or other, just SuperSu 2.52) I was flashed .zip file from Xda. I mean i was using L and after that .zip files pops out for MM, i just simply flash the MM zip file and got it worked.
After flashing kdz file with LGUP now my phone stuck at twrp. Now i stuck at twrp. I tried to restore my backup on external_sd but didn't work either. Any ideas?

LG Up can't wipe twrp , so tried flashing again with LG Flashtool with lastest driver.

I had same problem with it being stuck at 60% what I did was not to press cancel or unplug but pressed retry and it worked. Also change the language to English and the question marks will disappear.
As for the device disconnected issue i'm not sure how to solve that one you could try running flashtool in windows 7 compatible mode.

When can't go , I choose phonediag to CSEmergency flashing can finished.
I have use CSEmergency 3 times sucsessfully with CSE Flash and newest driver.

Solved my problem. The problem was using LGUP firmware to go back to stock. LGUP Doesnt work if you had root+twrp. Flashed kdz using the Lg Flash Tool 2014 ( I had really more problems when doing this but i made it.) Phone back to normal.

BOOTLOOP FROM MM 30B-Reason Faulty battery

Also tried using TOT file with showed error message that the model number is not same.
Now iam out of any options..pls somebody help to get rid of this boot loop.

i suspected it after doing some reading in xda...tried replacing battery with another G3 and it seems to
work perfect without any issues.
The battery is still showing some charge like 75 % , is it because faulty battery or some software bug
Any ideas
Thank you for your reply.

Because it's faulty

[Q] My G3 D855 shut down with no reason every few minutes

Yesterday I had a serious problem - my phone had a kernel crash and after a while of working on it I managed to flash through download mode. anyway, after managing to flash the stock 6.0 my phone won't enter to recovery mode, and every time I turn it on after a few minutes when the phone shut it's screen due to me not using it it won't turn on unless I would remove and put back the battery.. Any ideas what should I do? Thanks for every help!

I've Tried, tried through LGUP and it showed me unknown model so I couldn't do it with LGUP. Also tried with lg flash tool and had a disconnection with server and couldn't flash...
When I try to flash the 6.0 kdz it has the same message but after a while I press Retry and it flashes the 6.0 kdz.. after flashing the phone will turn on and work for a few minutes (not 100% ok) and then shut down again, with the ability to turn back on after removing and replacing the battery (and the all shut down process continues).

Think you flashed a KDZ that is not for your model.

I thought so too for a while, but i Double checked and I'm flashing the kdz for D855 European Offical (which is what I have)..

Thanks for everything, for now it works. I flashed all over again the marshmallow version and this time it didn't even turned off yet.

so after a day of using the phone is shutting down again and won't boot into recovery (since I have stock recovery) and won't boot into the android system - can only get into download mode. what should I do?

Maybe you have a battery problem, try another battery.
Verstuurd vanaf mijn LG-D855 met Tapatalk

that's what I've been through: kernel crash due to connecting the battery when the phone was connected to pc with usb cable. than after many times I tried flashing through download mode with lg flashtool it worked for almost half a day and then suddenly it crashed again (when I tried to install spotify on my phone). all through the process when I tried to flash a stock rom with LGUP it wasn't possible because of unknown model error. right now I re-flashed the marshmallow version (because for some reason that's the only stock rom which I can flash and it would work from time to time), and it crashes all the time after a few seconds of using it and getting back to boot loop. Mods I can enter: Only download mode (no recovery and crashes when try to turn it on)... Any ideas what my next move should be?

Lg G4 H815 hard-bricked with different qualcomm soft?

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

LG G4 Stuck In Firmware Update - Stock Reset?

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....
