do you have sdcard inserted in the phone ? or maybe you are mistypping partition name .... sorry for my english.
in linux that error is based on fstrim error, wich means that the memory hardware is corrupted.
If you want you can jtag that phone via Octopus box.

Just stop using your phone and keep it dead for a week. It will get back to normal.
LG G3 Fastboot
i am having the exact same problem with my lg g3, and i cant find the solution anywhere on the internet. If you solved your problem please kindly share the procedure.....
Same problem here
Any news from the topicstarter? I have the same problem as well on my D855 that only fastboot is working.
I am not sure what happened but my phone just rebooted out of the blue and booted android as far as the lockscreen when it froze and rebooted again. After that only fastboot is showing up.
*Update: I brought my phone back to the store and it is fixed under warranty. I haven't received a report on the repair carried out so I only can guess what they have done and that is that they have replaced the mainboard (different IMEI now). Good news is that it works like it should. It's shipped to me running Lollipop so I will downgrade to Kitkat but that's just my personal preference.
I have the same problem with D855, is it dead mmc? any suggestions, anyone knows something?
Same problem here. Anyone can help finding a solution for this?

Same Problem here.. Any luck ?
The pad is stuck at Download mode/logo ( turn it on , it goes to download mode, plugin computer without Vol up , also goes into download mod )
I already tried the lg flash tool 2014 tool with kdz file and it got server disconnection error after extraction.
With the offical LG Mobile tool (it can detect correct model ) which downloads 1.4GB, it fails after finish dowloading/extraction
The only method I have not tried is the TOT file which I cant find it for free . And I am not sure if I bought the file , it would fix .
So, does anyone get any idea about what happens ? bad / dead flash rom ? bad usb port ? etc. ?
Is there a way to force flash with diff TOT file like with V510 ?
TIA
The "Server disconnection" error dialog and other error dialogs are common and normal. 99.9% of the time if you totally ignore any error dialog, don't press any buttons in the dialogs, just at the most drag them out of your way and ignore them, then on the VK810, within 20 minutes I find that my VK810 is successfully flashed.
NOTE: Before we begin, let me tell you that from my experience the D851 does not require shorting at all. it will be identified as Qualcomm HS-USB in a brick state without any opening up, check your device manager!
Hello guys, I spent 2 weeks analyzing hex files in order to revive a D851 that I got my hands on. It was not an easy journey but I would like to share this with the devs or people who are looking at bring their bricks to life.
What I did was actually hack the Sahara programmer files that WillCracker (BoardDiag) programs use. This comes in the attached files. Seems like there was no site on the Internet sharing this unique files and thus not allowing us to unrbick the D851.
For a more detailed view of how I got these modified files created please look at this post
But with this uniquely created files we now have unbrickable D851's , I have revived one D851 phone that I had dead. Right now it already booted into download mode and it is loading the *.tot.
Instructions
Connect your D851 phone without battery via USB to a Windows Box.
Make sure you have installed the HS USB 9008 Drivers installed. If so you will find something called "Qualcomm HS-USB QDLoader 9008 (COMxx)" under device manager, make sure you check the COM Port number, as you will need this later on the next step.
Open up BoardDiag.exe (from the downloaded files here, as it includes modified files specific for D851) and select: B2 (MSM8974AC), and pick up your COM Port.
Under 'Image Extraction' select your bin which should be the *.tot file (I used LG_D851.10C_TOT&DLL.7z).
Hit the 'extract' button into a directory of your choice.
Pick under 'COM Port' the 'Target Dir' and select where you have extracted the *.tot. This will allow us to start flashing the partition files.

}
Select on the checkbox "AP check".
Check the box called "RESTORE BOOT IMG", in here start picking up the partitions, write each one of them (not system, userdata or cache -- those are worthless for now), and ONLY in the end flash LAF and then finally SBL*. After this you will see the phone boot up with the battery icon since you do not have a battery connected. This is when you can tell you have now the bootloader reflashed.
Unplug the USB cable, insert the battery into the phone and hold UP while hooking up the USB cable again. After doing this your phone will boot up in download mode and now you can go ahead and flash the correct firmware using a tool such as LGFlashTool.
Below you can see a screenshot of the dmesg showing that it is already in download mode (after being in QC HS USB 9008 mode)... I am so !"#$ happy
I flashed the partitions like in this other guide but please use the attached file or else it won't work.
NOTE: Do download the attached Willcracker Version I attached specific for the D851, this is a modified one and is the only type of program I managed to use to revive my phone. I cannot stop insisting that any other set of files will not work on our D851, which is what most people reported on the forums for some time.
EXTRA: Disable Windows driver update, updating the Qualcomm HS-USB driver can cause conflicts and problems on the process.

No problem man. I am also so glad to have unrbicked that phone as I can now give it to my dad as his phone (a really old Samsung Galaxy S3 was dying of slowness). I hated to have a ~$200.00 brick :cyclops: not being used! And I am a big fan of this LG G3 phone.
Btw, what I did after unrbciking first after fastboot started was that I shutted down my phone by removing the battery, and disconnected the USB cable. Then I reinsrted the battery and put it in download mode by using the: 'Keep pressing up and insert the USB cable'... and after that re-flashed the *.tot using downloaded mode as it is way faster with LGFlashTool.
Amazing work man… my D851 is working now. Earlier it failed to boot in all other methods. Thank u so much
@Omar-Avelar , Man, today i've seen my pm box and checked your message and looked here, nothing to say just.

I've faced the same fate as you because I flashed a D855 on a Phone that was a refurbished D851. Took me like a month to figure out how to unbrick it.
By the looks of it it seems that your phone still has the LAF partition of the D855 but you recovered the other bootloder partition files allowing you to boot into the download mode 'thinking' it is a D855.
I suggest you use the LGUP_8974.dll instead of the 'supposed' D851 *.dll in the *.tot files... I think that will flash the partitions regardless if it is a D855 or 851 and force enter the files.

Well, that images posted before whas with lgup_8974.dll and gives me the errors, I think I need to modify the hex file to put it as a "d855" and makes the program recognizes it, me fear is that if I flash the d851 firmware maybe I can loose the imei a mobile information ( before the brick the phone has d855 software ) or it will not erase my efs partition ? What u recommend me ? Flash d855 or d851 tot?

If it is a D851 motherboard but seen as a D855 via firmware I would try using the *.dll of D855 and the *.tot file of D851.
Seems like while being in HS-USB 9008 mode one of the partitions was not flashed correctly and the downloader mode still sees it as D855. The other option would be to brick it again with D855 *.dll and *.tot if the first try does not work. And while being in HS-USB 9008 mode please make sure you do flash most of the partitions there (not system, nor userdata, not cache) but the rest and end up with LAF > SBL* partition. That will flash the correct *.tot files for D851 and hopefully you will see the D851 now as D851 in the downloader mode.
I believe IIRC that the LAF partition has the downloader, and that's the one I believe is still written from when you overwrote it as a D855. If you wrote SBL* before LAF it might have booted with the LAF partition of the D855.
All done! Phone works and is alive!, @Omar-Avelar i've did what i told you, i've used a hex editor in a linux distro and modified the first "D851" mention to "D855" and goodbye CrossDL error, flashed sucessly, now my phone it's a real D851 and its hardunbricked! thanks all to you, you are great!.
Thank you, sir. You are live saver.
I have bricked my phone (d851) and I had been looking for days and nothing works.
Fortunately, I went to this thread and had successfully unbrick my phone.
God bless you.
D851 unbrickable

My case is almost similar. As per software info it was d855 before bricking. So I flashed mm kdz for d855 and bricked.then I opened the cover and found this has a d851 board. So ,as per this tutorial I flashed everything for d851.phone booted but booting into fastboot mode only no download mode. Then I followed some other tutorial and again flashed laf. Img .now it can enter in download mode. But have a big problem .As it was a real d851 rom it cant connect to 3g net work here in india(2g ok). Now I am so disappointed because such a good phone with 2g only.....
But how initially d855 rom was flashed on d851 board???? There may be a way..
Ofcourse only beacuse of thread my g3 is live now. Please help me to get full out put from that.
There are threads to manually add bands to qualcomm device.Can I go for that?

Yes, it is such a great feeling to be able to bring the phone back from the death.
BTW, I do believe also the phone bands can be changed using QPST since I have seen Argentinian D855 phones changed to D855P (Adding another LTE band).
You might need another phone reference (LG G3 that worka on the band you want) and using QPST might let you modify some specifics.
Go ahead and Google translate this post for analysis: http://www.grupoandroid.com/topic/112493-guia-habilitar-bandas-lte-para-argentina-en-d855-int/

Modified Files huh??
The miracle file is a file that has been around all along. It can be found in the Smartboot Diag Tool. Its called LGD851_ATMO_TMUS.mbn.
All you have to do is rename this file to 2nd_loader.hex and put it inside the Board DIag Tool > Model > B2(MSM8974AC) Folder. Replace this file with the old one.
Now start Board Diag tool and load and decompress your tot file, and flash away.
For other models, you could try renaming your devices mbn from the Smartboot Diag tool to 2nd_loader.hex

I am currently in class. Will check when I get home.
It has taken me many days to find a tool to flash KDZ AND TOT since many people show an error at 4% of FlashTool and there is no solution so this is your Post.
LGUP is a tool used by Lg for phones that still have a guarantee such as a system error or a software error.
Compatible with Windows vista/7/8/10 No macOS No Linux
Thanks to DroidTH for giving me a link
ok let's start
Renember: All will be erased in the internal memory.

Wait for the process to finish (Do not disconnect the phone)
At 80% the phone will restart (not yet to be disconnected)
When you reach 100% the phone must have turned on or starting on the TMO logo
If it does not start
-------------------------------------------------- -------------------------------------------------- ----
If it does not start
---------------------------------------------- -------------------------------------------------- -----
If it restarts constantly and does not enter the system (It restarts before reaching the optimizing application)
Turn off the phone completely and remove the battery
Wait 10 seconds. And put it back
Press Vol- and on when logo is released and press them again.
Give you everything
EYE: all files on the internal SD card will be erased
A factory reset will be made and then it must be turned on normally.
If it still does not start, remove the chip (SIMCARD)
Well that's all if you have any questions please write
Sorry if I needed something, it's just that I'm new and I do not know anything about xda
I hope you understand.
When I run LGUP it says Model is Unknown, then gives an error telling me I have to choose a known Model. Drivers are installed, USB debugging is enabled, not sure what else there is missing. Please help.
my phone: (T-Mobile lg g3 d851 30e)

sorry you had problems
the error is one of the drivers lg
you should plug it into one of the main USB ports on your PC.
or rather entering device manager and re-assign drivers to ports.
Have you downloaded the lgup for lg g3 and g2?
Drivers are installed, USB debugging is enabled, LG PC Suite OK.not sure what else there is missing.
Download : lgup-g2-g3.zip
Solve it FIX
good after I found the problem LGUP
roms apparently change the model of the device as it changes cm11 to build Cyanogenmod 11 xx
AOSP - to AOSP rom 2 etc.
the solution would be to install a stock rom clean no matter if v10 v30 etc. The important thing is not having changed the model number and manufacturer.
I hope I have helped and sorry
that includes cloudy fa's roms

the solution would be to install a stock rom clean no matter if v10 v30 etc. The important thing is not having changed the model number and manufacturer.
I hope I have helped and sorry

Hi !
How do I do all the above ?
My PC recognize the phone without problem, but LGUp won't start unless I "select a known model"... (LGUp window shows : Model = Unknown ; COM Ports = [COM5, CloudyG3] )
Problem is that my phone is softbricked after installing a new ROM, and I can only enter download mode (not even recovery). I just want to downgrade it and reflash a LG's stock ROM (or whatever ROM that would make my phone actually work !!! )
Can you help me do that ?

LGUP "UNKNOWN" and FlashTool failure with LG G3 (and possibly others)
When I downloaded and installed LGUP with the DLL installer stated to be for the LG G3, the program did not recognise the phone, reporting it as "UNKNOWN". The LG FlashTool also failed, reporting the IMEI and PID as NULL. After spending a lot of time on this, I twigged that the DLL file in the LGUP model directory was for the 8994 processor; but the G3 has an 8974, quite different and incompatible. I located the DLL installer MSI file for 9874 devices, uninstalled LGUP and the DLLs from Windows add/remove programs, ran the 9874 DLL installer and reinstalled the LGUP program, and everything worked.
The file is, amongst other places, on https://uptoandroid.com/download-lg-up-tool-for-lg-smartphone-latest/. Do not download DLL files for LG G4, LG V10, LG G3, LG Stylo, filename LGUP_Common_DLL_Ver_1_0_28_5 .msi, but instead For LG phones based on Qualcomm Snapdragon 800 MSM8974 SoC, filename LGUP_8974_DLL_Ver_0_5.msi:.

23 Aug 19: I find that I've rediscovered the wheel. Exactly what I said was posted in 2016 - if I'd found it, it would have saved me a lot of time!
Hello Guys
My friend ask me for get a Lineage OS to his H815 with Nougat. I agreed as I made few successful changes from stock to Lineage OS with Samsungs and older LGs (like L3 E400). But G4 is really more complicated, more than I expected . Firstly I wanted to unlock this phone with FWUL, so I download a VirtualBox emulated image with FWUL and after it boots I opened SALT program and it detects the phone. I made a basic backup and then I choosed Unlock G4 (UsU). After that some windows pop up. Last window was a pre-checking, when the bar gets to the end window closed and nothing more was happening. So after almost hour of waiting I just turned off the phone - I thought its all. After that while phone is booting I have those messages in the left top corner:
[820]-----------------------
[870]
[920] Secure boot error!
[970] Error code : 1009
[1020[ OFFICIAL !!
[1070]
[1120]-----------------------
Its booting, but only sometimes its normal boot, most starts are with bootloop, sometimes its start after 10 restarts, sometimes after 2nd restart, sometimes after plug in/plug out USB cable it starts boot normally (connecting cable only to phone, not to PC), sometimes only thing that helps is to take out the battery. I made full wipe to be sure that its not a software problem, but only thing I achived with that is fact that phone has a Nougat and now it have a Marshmallow. It is (was?) H815, but now model name is LGLS991 (?), it gets very long until it shows software version (V20g), IMEI is unknow, even when I type *#06# I get the null response.
I can get into recovery, can put phone into download mode. But i'm not able to do anything to get LOS or a least Nougat.
I've read many, many tutorials how to get G4 working properly after unsuccessful unlock, but nothing helps. What I've tried:
1. Flashing stock Nougat for H815 with LGUP, installed USB drivers, proper DLL, set com to 41, but when I trying to flash, after a 4% i get error: KDZ file is invalid. Downloaded few KDZ firmwares, dont belive that every single one is invalid, there is something wrong with LGUP or with settings, but I cant find what
2. Flashing with LG Flash Tool 2014: tried both normal flash and cse flash and always stoping in the same moment, with "Connection to server failed. Try again in a moment". Read many tutorials about this error, none was helpful in my case.
3. Flashing with LG Flash Tool v1.8.1.1023 and a TOT file, but after select of dll and tot file and press the yellow arrow I get an error: "Failed PreviousLoad()"
Tried all this methods on second computer but without a luck.
What else can I try to get this G4 working properly? Maybe try to install some rom from stock recovery? But which rom will be ok and dont get things worst?
If you need more info dont hesitate to ask. Would be very greatful for any advices .
you definitely didn't read enough... go to read again the UsU thread and as you've read the whole tutorial, you can also read the whole FAQ and the OP, because 90% of what you pointed out in your publication (which incidentally is in the wrong section) is explained there.
A quick advice: Don't try to flash any KDZ/TOT again.
