Cannot Unroot/Stock! LG Suport Tool stuck at 4%. LG Flash Tool Stopped due an error - G3 Q&A, Help & Troubleshooting

Hey Folks! I need help!
First sorry for my english, im from brazil.
I'm a Lawyer and i'm gonna sue LG company for a hardware problem ( SIM CARD REMOVED PROBLEM ). But my LG G3 have LG 6.0 Stock rom installed. I tried to root with King Root, it failed, but now even if i hard reset the phone it keeps installed!
(in brazil unlike USA, the company's don't support the costumer. They have given 1 year guarantee, i have the phone for 1 year and 1 month. They told can't help me but the brazilian Law says that if a unkown hardware problem appears then you have 90 days to sue the company.)
So i want to Go back to stock 4.4 ou 5.0, so if the judge need to avaliate, at least it will be known as unmodified.
When i updated to 6.0 Stock, i did with LG Flash tool 2014.
So i tried again to downgrade with LG Flash tool, but using the 20x kdz. I tried diferrent KDZ. My phone is D855P, tried D855 normal KDZ, tried 855P KDZ. but downgrade always failed " due to an error " on flash tool.
So i tried LG support Tool, gone do Download mode, but it stucks at 4%. ( and yes i tried to hard reset before starts the procedure.)
Someone can help me to unroot(i don't think is unrooted, but King root remain on the phone as a bloatware now), or return to 4.4 ou 5.0 stock?
thanks!:good:

Assuming you able to boot the phone, try to downgrade using LGUP instead lg flash tools

I was thinking about. As i already use "stock rom 6.0" and i just figured out how to uninstall "king root app". So now my Phone looks clean from bloatware. Guess now i can sue the company without being afraid of someone detect some mod on the smartphone.

@jellysteve
I've solved my mirrorlink problem like this
I have G4 europe H815, brand vodafone
Search in this site kdz vodafon file
There's very few files kdz vodafone, not found for italy
I find in this link posted by a great guy here
Don't know if i can post the link, i have few posts
I can't, anyway, it's the list of kdz files here on the 3d "go back to stock G4"
I've download "portugal vodafone v10b"
It'real 10b, not 10c as some called 10b
Normal flash with lg support tool
And the vodafone 10b was in my g4
Automatically i find OTA update for v10c, 330mb
After the update with ota
The problem mirror link it's solved
So, you have mirror link problem after kdz file v10d?
Or problem after OTA update v10d?
Hope i can help-)
Hi-)
Hello the mirrorlink issue is since OTA update
I found a kdz on the lg phone firmware website but the link for download doesn't work any idea ?

Hello
The link doesn't work even for me
So mirrorlink on g4 it's not easy to solve
You have international g4, so model H815?
I can't post links for now
I can't say this is the solution for you
But i solved mirrorlink in this way
Go here in the Forum at the section for G4:
G4 General- [Guide] LG G4 Stock Firmware (Go Back to Stock) KDZ & TOT Method by hyelton
In the middle of the post there's:" KDZ Firmware Files; HERE"
Click HERE
A link will open with some kdz files for G4
Download kdz before v10d
Important, your g4 is brand or no brand?
You have choose the right kdz for your G4
If you have H815 europe, try d.load these kdz file:
Europe General H81510B_00.kdz 1697378KB Jul 06 2015 04:43:29 PM
Or kdz files of your provider, if there's in list
As most of v10b kdz, it's not v10b, but v10c
Good for you 'cause you have v10d
Run lg flash tool 2014
Put kdz file
Select CSE flash
Leave all the others fields as they are
If Cse flash don't work, do normal flash
At the restart, you'll find v10c
And 99% find the Ota update for v10d
Before the Ota update do a hard reset
At the restart, run the Ota update v10d
And see if mirrorlink works
If not, with lg bridge run "fix update error"
Don't do with lg bridge the software update, this will put mirrorlink error
If you have windows 10, maybe Cse flash will not work
No prob, normal flash work back to v10b-c
Hope will work
Sorry for the long post-)
Yes I comfirm my g4 is h815 unbrand.
I found the kdz v10d for France it's my actual version.
I'm ok with the process : lg flash tool.. question if I use normal flash it's necessary to make hard reset or not.
Thanks for your help and time ?

The point is to go in downgrade, v10b or C
If you keep kdz file v10d, i think the problem remains
Your G4 is no brand, so in the link if kdz files try d.load the file kdz i've posted above
With flash tool try normal flash
So you have v10c, then accept the Ota v10d
And see if mirrorlink is solved
If not, do hard reset
Then with Lg bridge do fix errors update
I'm italian but i live in France like You
In this time is almost impossible download flash tool and drivers
Many french sites in these days have put in web around 50 virus
Keep update-)
Hello
I found V10C and I downgrade my g4 with flashtool and I make the update with lg bridge and same problem with mirrorlink
I make a hard reset and same problem I don't understand
I think i wait a new update for solve perhaps the problem.

Well mirrorlink is hard to solve
I've done the steps to solve m.link by my idea
Can't found nothing on web
I don't know if you have patience to make again all the steps
You said you update with Lg bridge after downgrade v10c
Only my opinion, this is the mistake while I'd m.link problem
I said in my previous post:"don't do with lg bridge the software update, this will put mirrorlink error"
If you want to retry
Downgrade v10c, wirh cse flash, then wait the OTA update, not update with lg bridge
The best way is downgrade v10b, like i did for vodafone
But v10b no brand kdz is hard to find
It depends what problems create m.link at your g4
If it's only the message at start, it's not bad problem
In my case, many icons of app on screen disappears
I hope is not your case
Just value the problem, only a message, it's not so bad
As you said, with a new update the problem should be solved
Hi-)
It's my guess, but i think mirrorlink problem will persist for those, who has unlocked bootloader and ignored LG warning that some apps, based on DRM will stop working

I totally agree
I'd unlocked my vodafone bootloader
And so here mirrorlink problem
It's strange that i've solved with downgrade and Ota update, but not @jellysteve case
Mirrorlink is useful if you have a modern car that fit with
If like me, i have a modern car not compatible
The error message m.link can be ignored
I must fix 'cause many icons of apps disappeared at start
But it seems icons problem, happened only for my G4!
Then, with windows 10 i can't do cse flash
So i go back to Win 7, and cse flash works
Hi-)
I started to face this problem, but my H815 fully stock, no unlocking, no rooting. And I wish it to stay that way for now... So the only solution for me is wait for LG to fix that?
Weird thing, I uninstalled quick circle apps, quick remote and quickify, and the problem seems to be gone

Is your bootloader unlocked and are you rooted?

no, I'm not rooted, bootloader locked. I started having this issue when I started experimenting with various apps for quick circle case.
Hello, maybe my solution will help for you too. Ive got h815, locked bootloader with low effort root.
Ive installed super manager app with root permissions. In the app go for the system folder, when you trying to enter switch system folder to r/w (the app automaticly asks it). Go to the priv-app search LgCover folder and rename the app inside of it with .bak extension. Reboot the phone.
After that repeat the process but you should remove .bak from the end of the app's name (back to the original) and reboot again. Mine started to work without any issues. I guess that will work with the mirrorlink app. Location of the app: system/app/MirrorLinkServer folder. You should do the same thing with it
Good luck

G-Pad 10.1 Verizon Return to Kitkat (VK700)

Hi, All. Ive followed XDA for a long time and love it. I love my verizon G-Pad but ever since the Lollipop update it has just been so slow and almost unsuable. Well ive got good news. Today i found a way to downgrade back to LG Official Kitkat 4.4.2.
Tool Used: LG Flash Tool 2014 - you can download from this thread
http://forum.xda-developers.com/showthread.php?t=2785089
I could only get this to work from LG's Download Mode (with tablet turned off, hold the Vol Up Key and plug in USB cord)
If you are running version 23A Lollipop you must downgrade to 22A first. Attempting to downgrade straight to 11A (Kitkat) will fail at 57% restore.
After downgrading to 22A, allow the device to fully boot then shutdown and return to download mode
Now push 11A firmware, everything should now go smoothly (at least it did for me)
Firmware Download and LG Flash Tool Bundled

Many Many thanks to the Devs of the LG Flash Tool for such a wonderful utility on LG Devices
tutorial?
How do I downgrade to 22a?
In the Firmware download link I've provided is the 22a and 11a firmwares. Follow the LG Flash Tool link for usage.

Hey man gotta question, my pad was on lollipop and only rooted with no real tweaks and I rebooted one day and it sticks at the Verizon logo. I can get to stock recovery where any selection goes to fastboot where any selection goes to a blank screen where I have to kill it. The couple others I've seen with this problem had success with the support tool / update recovery deal but mine says everything is up to date. I tried flashtool with a kdz and I get all the way to it supposed to send it but the tab download stays at 0% and nothing happens....I would rather have kk anyway would it be worth trying this , **** can't hurt the damn thing no worse lol tired of it sitting in my dresser where its been for months ...I really wonder wtf happened to it
EDIT...... OK I feel like a real dumbass lmao... Apparently the pc I was using had an Antivirus on it and apparently the flash tool doesn't play well with an Antivirus
OK has anyone found a twrp that will flash correctly on the vk700? The twrp floating around for gpad 10.1 only works on the v700 cuz its been bumped To work on the locked bootloader....

Does anyone know if it works on v700 ?

Well this downgrade is for vk700 not v700 which is a big difference, I found that out by trying to get twrp to work on my vk700 when it's only for v700 which if you have the v700 your better off

Help save a bricked lg g3

:crying:
My issues is quite complicated. Please be patient and read on.
Less than a week ago, I bought an LG G3 D855. It wasn't brand new and definitely out of warranty.
It was on the 4.4.2 Os version but I couldn't update it because I couldn't locate the UPDATE CENTER and after some research online, I found out it was because it was rooted. I couldn't find a Supersu application anywhere on the phone anyways but Root checker confirmed that it was rooted.
I downloaded the stock kitkat firmware in a .tot format and I tried flashing using LG Flash Tool for TOT but it failed because "Device version is different"
I checked the Imei online and it stated that the device is a Sprint LS990 but the details embedded in the phone all say it is D855
I checked online and found a couple of posts about this error and one user said he was able to fix it by flashing the actual Sprint .tot with the lg flash tool. I tried that but it didn't work. It still said "Device version is different. Check BIN or dll"
I checked online and found results pointing to a generic .dll file for G3s and I downloaded it but when I used it on the Flash tool, it resulted to an error "CrossDL blah blah"
So I found a Marshmallow kdz file. LGUP won't see my device model so I was able to flash it after editting the software in my build.prop to D85510n.
***I have always changed the port to COM41 in all the steps I used
The LG UP detected my model and it flashed to 100% but got stuck on a bootloop by loading the lg screen, freezing and restarting by it self. It never gets to the homescreen.
I downloaded lollipop kdz reflashed using LGUP in a form of downgrade and it got to 100% and got stuck at the lg screen while trying to reboot.
I redownloaded the stock kitkat rom and used the Lg flash tool but it failed. It said 'PID null IMEI Null"
I used LGUP to reflashed. It came to my understanding that the LGUP can flash both kdz and tot. So it flashed to 100% but got stuck at the lg screen and I have tried all I can but it is stuck. It can go into download tho. I don't know what to do about the IMEI. I don't know if the last flash retrieved it. I don't kniw what to do.
It no longer shows as LGE AndroidNet USB Serial
Please can anyone help me?
I just need my phone to work again. I was stubborn and now I regret it. I should have just stuck to kitkat. I'm so desperate to get my phone working that I wouldn't mind Android Froyo Os if it was ever possible.
PLEASE HELP!!!
I think you have to repair the IMEI...
maybe this can help

I think that he forgot to hard reset after flashing the kdz.
i completly know what you should do:
1: force your phone into qualcomm 9008 mod.
2: use board diag unbrick instruction and it will boot on download mod. for unbrick you will need best kitkat tot for your G3 model.
3: flash best lollipop or kitkat tot to make your phone alive
and then flash it with any kdz you want(it should be for your G3 model)
my telegram ID : @Erfan_rv
pls help me
Apparently, it seems my bricked phone keeps disconnecting during flashing process. I dont think it the fault of the cable because I have used different ones and they all seem to work fine with other phones. I have tried a different computer and still the same results. it connects as qualcom 9008 but once I try to start flashing, it disconnects and interrupts the flashing process. my phone just shows a grey screen now when I power it up with the battery in. also, I was trying to upgrade from linear os to the latest linear os. I cant fine the tot out there so im using zv6 currently. could this also be the problem? thanks in advance

I have been trying to root my LG G3 D852 on 6.0 mm, i have found that there is nothing out for that yet. I know know that have to downgrade and I have tried but since I'm on virgin mobile so the downgrade file I tried to use bricked my phone so i had to send it back to LG to get it fixed. Is there any other way to downgrade or root without bricking my phone again?
Thanks

Hmmm. I had the same problem as you did with my G3. Same model and everything. Tried to downgrade it using my computer. Can't remember what tool, but it said it completed successfully. When it went to reboot, it would stay on the LG logo for 15-30 seconds, before going to the broken android screen. After a few minutes, it would reboot. Could enter into the recovery menu from the broken android screen, but when I tried to bump the files or flash a rom, there was nowhere on the phone to store it. I think it removed the partitions during the flash, hence why it couldn't store the files. It's not that I didn't have permission, but it showed in the console that there was no directory to mount. Couldn't even charge the phone in the state it was in. Guess it relied on the OS to control the charging. I'll probably try to simulate the phone, with the stock OS, and see if I can find any exploits that could allow for a "safer" rooting method. Tell me if you find anything yourself!
