download drivers, LGUP, and the corresponding KDZ for your phone. i have tmovile H811 we have antirollbackwich mean V1 V2 V3 of course V1 is lollipop or kikat i dont know.. so if i flash latest 20p for my phone wich is marsh mallow am on V3 antirollback. i can not downgrade to V2. so i must stay at V3.. have in mind that not all G4's can be bootlolader unlocked.. and once you in MM. you cant root. root its only possicle on lollipop with locked bootloader.
so if you have locked bootloader and want root i suggest to stay in lollipop. if you dont care for root then use latest MM available for your phone.

firs thing is have the correct drivers. use the ones in the LGUP.
if no go then try it on another computer. if it works then its not phone. i have had times when no phone would recognize. i had to do reformat my pc. that helped. i search and could not find other way to fix .it.. so try it in another computer. as for question it could be that its separate, am not sure.

Hello there,
I have the same problem with my G3 D855.
I send it now but at the LG customer under warranty.
Let's see what it comes out.
Fixed by doing the shorting method. Flashed v10* instead of MM like I was supposed to, but I got to download screen and reinstalled MM

Hey, please share the outcome.
Hey ho,
I'll keep you posted.
The support has now sent me the repair order and the shipping label to the next repair service. On Monday my G3 goes on tour.
Hopefully it is then end of the week back.
As a repair base I had given an update error. Which was caused by the "LG PC Suite" program.
Hope this helps

Hello there,
Yes, the way I have already looked at.
But I have warranty on my G3 until the end of 2016th
Since I try only so dear, and when LG says no because then I try this out.
Would not be the first mobile phone which you have to open and to repair it ^^

As far as I undestand yes. You need an specific LP version but Im still trying to find out this. The thing is that every root method is now outdated and my phone came from warranty with a newer version. I just dont know how to proceed.

Ok, according to http://forum.xda-developers.com/g4/general/psa-warning-try-to-downgrade-g4-t3197675 (bottom of first post) you can safely downgrade h811 from 20i to 10n
This whole situation could be clearer tbh

T-Mobile H811 10N.kdz on back to stock guide from hyelton.. http://storagecow.eu/index.php?dir=Xda/LG+G4/T-Mobile+H811/ 10N..
I came from G2 Dorimanx too Hard combination to beat. You should find the G4 pretty good when you get it set up.

Things to consider:
Windows 10 may not work. I tried for over a day trying to backup my stock system.img using Windows 10 until some guy from another forum told me Windows 10 was probably having incompatibilities with the drivers.
Rooting. I had to make a VirtualBox virtual machine running the last version of Ubuntu (Took me 10 mins in total -downloading-setting the VM) but I also downloaded the files directly to Windows and copied them to Ubuntu. When I was rooting Ubuntu was missing files that were not compatible to copy & paste from Windows to the Ubuntu VM. So download the root_inject files directly to Ubuntu.

Yup that is the low effort root. That one is good when you have a stock room available, in your case V10N.
I went with the Ubuntu one because the version my carrier installed seems to work pretty good so I just needed root and had to do the 3 step rooting method with Ubuntu.
Enjoy!

well i just have root and xposed installed... .
i was told i idnt have balls to unlock bootloader... if he only knew
well i guess you dont know. as you told me i could not root and use xposed without bootloader unlocked.. guess i prove you wrong. as for grow balls dont even go there.. you dont know and once again i can prove you wrong... this isnt directed at you pakito someone else that siad those things.. he said bootloader can be relock and ive never said it couldnt do it.. all i wanted was warrranty. as even new 6xx are getting bootloops...
Whoever said it was not possible to root and xposed with locked bootloader is clearly living in the past. I had Xposed before I sent my phone to warranty, right now Im just trying to figure out why is not installing on my device.

The only flashing method that has ever worked for me when my phone was bricked along with Corrupted recovery is the .TOT method. And that I'm afraid is the one from where you have to start all over from Out of the box experience with 4.4 Kitkat. If the LGFlashTool2014 does not work for you, I recommend the LGFlashtoolv1.8.1 + the crack. It will not ask you for the KDZ and should allow you to downgrade without any hassle.
There are 2 things you will need:
LGD851AT-01-V10c.zip & LGFLASHv160.dll
This will point you in the right direction. Just scroll down to the text where it says "2014 TOT Method (Old/Outdated)"

Solution to LGUP LG G3 unknown
While an old thread, it'll be found in searches. For anybody who gets "UNKNOWN" device with LGUP for the LG G3, I found that LGUP for the G3 is often distributed with the wrong DLL file. See the details here, post #11.

LGUP worked with my LG G3 D851 when I used it as in this tutorial:

Your using a usb 2.0 port correct? USB 3.0 won’t work.

It appears that the LG G4 model for Israel is H815L - you want to confirm that is your model and then look for the firmware for the 6.0 kdz for that model for your specific carrier and, as suggested above, use LGUP-NEW (https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803) to upgrade.
The H815L model doesn't appear to have a bootloader that can be officially unlocked (I will stand corrected if that is not the case). If correct, you will not be able to root your device with android 6.0. You can however root android 5.1, following this guide: https://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586
If you bought the phone originally from your carrier in Israel and LG didn't provide you the correct motherboard for your phone when they repaired it, you have a good case to go back to them and insist on the correct one.

: ) its h815 its right in the hardware info.
in the bin action LGUP all the time he didnt find the kdz i try to downgrade back to lolipop or install a fit MM for my device.
i try both USB 2.0 & 3.0.
the device steel was in warranty so the company that deel with that replace a new motherboard for h815.
i beleive that i miss something in the LGUP about the lg flash tool you allready tell me that i cant so i must use this one with new instructions : )

But what error do you have in lgup?
What do you mean by hardware info? Only real way to know it’s have the phone apart and look at the actual motherboard. Hardware info will say whatever firmware is flashed on it.
If LG them selfs didn’t warranty it it’s quite possible it has a different mode motherboard. It’s extremely common with the G4.
All you do is run lgup, choose refurbish and choose the kdz file. There’s nothing more to do. Just don’t use usb 3.0 as it won’t work.

The H815L model doesn't appear to have a bootloader that can be officially unlocked (I will stand corrected if that is not the case). If correct, you will not be able to root your device with android 6.0. You can however root android 5.1, following this guide: https://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586
If you bought the phone originally from your carrier in Israel and LG didn't provide you the correct motherboard for your phone when they repaired it, you have a good case to go back to them and insist on the correct one.

You upgrade to go from 5.1 to 6.0
You refurbish to go from 6.0 down to 5.1

In LGUP-NEW, in order for it to find the kdz file you have downloaded, you must first select upgrade and search for the file/folder where you placed the kdz you downloaded. If downgrading, you still have to select upgrade first, load the kdz when you select it, then close the LGUP-NEW app. When you re-open it, it will have the file that you selected ready to go and refurbish will already be selected.
Make sure that you are using LGMobileDriver_WHQL_Ver_4.2.0 on your PC as your driver. You can download it from the LG US support site, if you are not using the correct one.
As hyelton suggested already, the only sure way to know what your motherboard is, is to open the phone and look for the model number on the motherboard. My suspicion is that you should be using an H815L kdz but without motherboard model confirmation, one cannot be sure.

It sounds like a DLL file issue. You will need the correct DLL files for your phone model.
You could try using UPPERCUT: Add Any LG Device to LGUP for TOT/KDZ Flashing (G4|G5|G6|V10|V20|MORE???) from this thread: https://forum.xda-developers.com/lg-g5/development/uppercut-lgup-loader-g5-variants-t3511295

You could check out this kdz: https://forum.xda-developers.com/g4/general/kdz-firmware-v20i-france-2016-10-04-t3474227
Seems it can be flashed (LGUP-NEW) successfully on a lot of different H815 models.
See if you can change the language in your settings. If not, read through the posts in this thread (https://forum.xda-developers.com/g4/help/lg-g4-h815-hebrew-removed-restart-t3186330/page2) - one of the members has posted an app (in post # 12) that will help.
That's all I got for you. Wish you luck.

hyelton said:
But what error do you have in lgup?
What do you mean by hardware info? Only real way to know it’s have the phone apart and look at the actual motherboard. Hardware info will say whatever firmware is flashed on it.
If LG them selfs didn’t warranty it it’s quite possible it has a different mode motherboard. It’s extremely common with the G4.
All you do is run lgup, choose refurbish and choose the kdz file. There’s nothing more to do. Just don’t use usb 3.0 as it won’t work.

Thanks for letting me know. Glad you got there.
If you want to gain root now, check out the following thread: https://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586
You can then install Xposed when rooted and customize your rom a bit.
I would also suggest you check out steadfasterX's TWRP-inFiSH (https://forum.xda-developers.com/g4/development/locked-twrpinfish-locked-g4-devices-t3573048) - it's a custom TWRP version developed by him for LG G4's with locked bootloaders that will allow you to back up your rooted system image, so that you can always restore back to where you were. It works like a charm and I recommend it.
great!

Suggest you check out the following link: https://forum.xda-developers.com/g4/general/guide-unbrick-via-external-sdcard-qfil-t3748946
steadfasterX has more knowledge about lg hard bricks than anyone - post your issue there and see what he suggests BEFORE doing anything. Your issue may not be exactly the same as the issue he describes how to solve in that thread but he will be able to suggest the best course of action for you to follow.

Those refurbished franken phones become very inconsistent after software modifications.
Before anything the best is to dissasemble the phone and see on the motherboard wich is the real model. After this you can download the right firmware for flash the device and it should be back in the game :good:
