system.img firmware only -from 10F KDZ file

HERE is the system.img firmware only from 10F KDZ file, should work with all variants of the G4 (i hav'nt tried it myself yet, as im away in hospital all day)
DOWNLOAD HERE
It's google drive so quata will go fast, so if youd like you can mirror it.
Download the system.zip file and extract it.
instructions by TEAM_CodeFire modified by smaberg
1.) install all windows driver and adb, fastboot files, download and extract LG_Root for appropriate files http://d-h.st/uO8h
2.) Enable ADB debugging on your device, Go to Settings > About Phone > Software Information and tap build number until you are presented with "You are now a developer"
Exit back to Settings main screen. In Developer Options enable USB Debugging (Some devices require enabling PTP for debugging to work)
3.) In the root of LG_Root folder start a command prompt, Inside of LG_Root folder hold shift and right click a blank space you should see "Open command window here"
4.) Well that was easy , let's continue (Now that we have the files on our device we want to put our device is download mode)
Power off your device
When the device is powered off, hold volume up and insert a USB cable connected to the PC
Wait for the drivers to install
5.) Let's find which COM port our device is connected to
Double click ports.bat (This will give us the COM port in which our device is connected we are looking for the Diag port)
Let's run Send_Command.exe (It couldn't connect? Make sure you COM port number is correct it varies)
Code:
Send_Command.exe \\.\COM3
6.) in command prompt Type "id" and press enter (no quotes).
You should get back some text starting with "uid=(0)root gid=(0)root". If not, press CTRL-C, and do step 9 again (the application sometimes doesn't respond on the first command).
7.) in command prompt type
dd if=/data/media/0/system.img bs=8192 seek=55296 count=529920 of=/dev/block/mmcblk0
For other variants then eu815 look here
8.) After a few minutes of sitting, you should get back a "#" prompt. This indicates the process has finished.
Type "LEAVE" (no quotes) and press enter. Your phone should reboot. DONE!!!!!!!!!!!!!!!!!!!!!!!!!!!

All flashing is on your own risk, i cant help if you get a seagull in your face

It´s rooted?

no, stock at the moment.

No possibility to have a zip file? I do not have windows, but only Mac.. with a zip file for who has the unlocked bootloader is simpler

I tried it on my Sprint variant but it did not work.

Ofc, its for the H815.

is it possible to change the build.prop in this .img before i flash it into my G4?

Could you post a link to the 10f kdz file?

Where did you get that? Was there another update this week?

Look at the date of the OP. This was posted weeks ago.
There are different version upgrade paths for different G4 devices.
For example, my TWN (Taiwan) device latest is 10C. You should really only use the version designed for your own device.

You're right. I didnt check that after being redirected here from rooted img thread. This software misleading stuff provided by LG is confusing. Sorry once again.
LG G4 H815 ®

when I flash the system.img I lose the exfat support for sdcard , I downgraded back to v10E with kdz flash and it fixed sdcard issue.
I will be very thankful to get 10F kdz
I think this way I won't lose exfat support .

Hey nechmadi,
i'm quite sure that any available KDZ is and will be listed here http://storagecow.eu/index.php?dir=Xda/LG+G4/ (link is from this thread). depending on what device you are using (it appears to me that there's a mess with version numbers among carriers etc... i'm using a no-carrier H815 international device) v10d/e* is the latest.
(sais v10d in UI, but v10e in build.prop)
my humble advice, stick with what you have, enjoy your sd card and just wait for future upgrades to see the light of day
edit:
hmm, i see 10f mentioned here.. i didnt get anything 10f related so far... since i'm using a dull no-carrier device i think that's where 'LG updates' arrive first? i'm fairly new to this whole ordeal so take anything i say with a grain of salt - however i'll stick to my previous statement. sit and wait

unbrick LG G2 Force Flash with Send_command.exe

Use it if you cannot flash with any flash tool (no root needed)
Note: Use this at your own risk! Use it as a last resort!
I'm not responsable for anything, this may not work with yours
Sorry for my poor english. I tested this method with MY bricked LG F320L, no root, no boot, no many partition pop up, partial
downloadMode (just download mode and can't see the USB logo nor S/W update) then can't flash with KDZ/TOT file,with adb mode
recovery when holding pwr and vol+ ( lucky ), with stock recovery but I have to write adb reboot recovery to get it
what you need (sorry, I'm too lazy to put a direct link, I found all of them in xda):
- Install driver for your device
- .kdz file of your model
- WindowsLGFirmwareExtract-1.2.5.0-Release
- Send_Command.exe and ports.bat (ports.bat is optional if you know the port where your device is plunged can be in LG_root.zip)
This methode needs that you can access to downloadmode or partial downloadmode like me (vol+ and plug USB cable)
1- Run WindowsLGFirmwareExtract
. browse your .kdz file with "Open" button
. click to "Extract KDZ" button and wait until finish
. browse the .dz file abd extract it with the appropriat button
. click to "Extract DZ" button and wait until finish
. select all system files and clic Merge system-bin (you will get system.img in another folder and you don't need all system****.bin)
. copy all files in same folder
2- change extension of all files .bin to .img and remove any numbers
example: aboot156.bin => aboot.img / 1-aboot.bin =>aboot.img
3- Push or copy all files to your device. You have to find also the laf.img of your device, sometime it's not in the KDZ file.
Maybe it's optional, but I'm not sure.
Remember the path, for this tuto I'm using adb and push all files to /data/local/tmp/
You can also copy all files with another method
4- Run Ports.bat
Double click ports.bat (This will give us the COM port in which our device is connected we are looking for the Diag port)
keep in mind the COM of \Device\LG*******DIAG*
5- Go to downloadMode
6- Run send_command.exe in command prompt
type: Send_Command.exe \\.\COM3 if COM3 is the port where your device is pluged
wait for #
flash all .img like this, replace NAME by the name of the file ex: aboot.img replace NAME by aboot
dd if=/data/local/tmp/{NAME}.img of=/dev/block/platform/msm_sdcc.1/by-name/{NAME}
ex: dd if=/data/local/tmp/aboot.img of=/dev/block/platform/msm_sdcc.1/by-name/aboot
Except for backupGPT.img, I don't know what is it. Maybe in this partition:
dd if=/data/local/tmp/backupGPT.img of=/dev/block/platform/msm_sdcc.1/by-name/gpt
personally , I have not flashed this one
If you have finished type: LEAVE
Flash completed

Thank you guy, your tuto saved my device

@santatralalaina
I'm in a similar situation like you. No download, fastboot or recovery and phone is not detected by Windows. As u said PARTIAL Download mode only. I'm not very good with adb also. Could you please guide me about force pushing of the .img files please! Where can I get send command.exe and ports.bat? Could you please attach some screen shot of Step:6. Renaming the file and command is bit confusing for me.

Hi, Don't panic! Take a deep breath.
Firstly: What is your phone model?
Secondly: What happen when you plug your phone to your PC?
Finaly: What you have did to try unbricking you phone?

Hi..thanks for the reply....My phone is G2 F320L..Korean version with removable battery and SD card....I tried to install a non compatible ROM..got bricked with only fastboot...Then I try to flash aboot.bin..boot.bin..laf.bin..etc files (which I have extracted from the kdz) through fastboot...during flashing my phone was disconnecting and connecting back again...thats where all the problem started I guess. Now I dont have fastboot also. If i connect my phone to PC.. LG logo comes on the phone screen...on PC it try to detect as LGE android MTP devices and try to install the driver of the same. But the driver installation fails eventually.... At windows device manager it show as LGE Android MTP devices with error code 10...and showing connected to port:COM3....If I try to get in to the download mode..it get stuck at the (.............) download page...it is not going to the page with big USB picture...
My thinking is...Since the device manager is showing that it is connected at COM3.....Can I force flash the boot.img, aboot.img, laf.img etc files with "Send command.exe?
At least I can try to force flash right? If it is possible..may be I will be able to enter in to the download mode:fingers-crossed: Right? Where can I get this "Send command.exe" and how it works?

Hello,
It was easy to unbrick the fastboot but now... ok, you are stuck in LG LOGO but after no black screen? can you charge you battery? And if you try to go to RecoveryMode, what's happen? do you have multiple partitions and QHSUSB_DLOAD trying to be instaled? It's also easy to unbrick the QHSUSB and if it is the case, don't use send_command to flash manualy your device.
Maybe, you can force flash. You have to find a solution to push all .img files to your device. If you cannot use ADB, try to put the img files to sdcard.
you can found send_command.exe and ports.bat in this zip file, it's an utilities for having root on LG G2 :
LG_Root.zip
you can use all root command with it!

Hi!
As I known, LG G2 is unbrickable
This method is for last resort because I havn't complete documentation about this!
I've tested it with my own LG F320L only
Try to flash with TOT files or LGUP
Try to repair the download mode http://forum.xda-developers.com/showthread.php?t=2706590
Try to force the QHS_USB to appear then use the appropriate tools http://forum.xda-developers.com/lg-g2/general/file-unbrick-qualcomm-9006-qhsusb-t3056800
Try send_commande before shorting testpoint (it's less dangerous IN MY OPINION)

I just wrote and shared my experiences. Forcing the qshusb by shorting the right pins in the motherboard is the only solution if you cannot push the img files to your phone with adb, by sdcard, by MTP or something else

Modify system.img on Marshmallow ROM locked BL to gain adblock, edit build.prop etc

Hi
I wonder why no one is doing mods as the Sprint G4's forums are doing http://forum.xda-developers.com/spr...-mellowmallow-debloated-60fps-camera-t3341993
Take a look at this, they are using Send_Command exploit, as used in Lolipop to gain root. Many of you after MM update thought the LG blocked this metod but actually we can use it again. Just start flashing any .kdz by LG UP and at 9% at computer, and when green COMx shows on screen just unplug USB.
After that run Send_Command and you are root. We can dump system.img, modify it in any way and using dd command, flash it back to phone.
I am 100% sure this will work.
We can't gain ROOT on Marshmallow this way but we can de-bloat and put modifications or even themed/modified stock LG apps.

It's for both (H815 & H818). Check again.

Last night I actually modified my system.img
I have right now 530DPI, all apps in Dual Window and louder headphone output.
Edits were made to /system/build.prop and /system/etc/mixer_profiles.xml
Everything is working great so far.

Now keep in mind if u pull the plug to late you risk hard bricking. There have been cases reported. And this is a dangerous method but it does work

You can check out my github repo for examples.

Last night I actually modified my system.img
I have right now 530DPI, all apps in Dual Window and louder headphone output.
Edits were made to /system/build.prop and /system/etc/mixer_profiles.xml
Everything is working great so far.

Anyone tried this?

The commands are the same for H815P, H818P and international H815. You can use this translated page to do it yourself but be aware - google translate messed up commands so go copy them from source, not this translated text.

Out of curiosity, would it be possible to add root to this?

No, you can't root Marshmallow without modyfing kernel (boot.img) and you can't do this because you have locked bootloader.

On what firmware this thing is based? 20a? 20c?

LGUP for most International, and Domestic G5s

I have done my best to make sure most of the LG G5s out there will work with LGUP.
DISCLAMER: first and foremost, I take NO responsibilities for the possibility of a bricked phone(none whatsoever). if you brick it, it's YOUR fault, not mine.
ALWAYS BACKUP YOUR DATA BEFORE YOU DO ANYTHING
now for the fun bit:
1. Download and extract the LGUP.zip file from here as it contains everything you'll need except the firmwares.
2. To install the drivers for the device, go to the Drivers folder located in LGUP, and select InstallUSB.exe for a 32-bit system, or InstallUSB64.exe for a 64-bit system.
3. Install LGUP_Lab_Frame_Ver_1_11 that is in the LGUP folder
4. Install either the G5x86.reg or the G5x64.reg depending on whether you have a 32 or 64 bit windows installed.
5. Put the "model" folder in the LG Electronics\LGUP folder which will be either in C:\Program Files or C:\Program Files (x86) depending on whether you have a 32 or 64 bit windows installed
6. Put phone in download mode ( Phone off, vol up while plugging in usb from PC), start LGUP
7. Make sure you see a com # and phone model and at the bottom where it says BIN, select it, at which point you should see 3 dot on the right, select it and choose the .tot or .kdz file listed for your device, then hit start and wait for the magic.

Any possibility of achieving root with this on locked bootloaders?

From what I understand, as long as the stock firmware is published by LG or the carrier we can inject root.

This only if the model support the fastboot oem unlock command.
Without an unlocked bootloader is not possible to obtain root on Marshmallow, the only way would be find an exploit.

A992 in OP is typo.. should be AS992 obviously.

Thanks a bunch gwolfu. However, what I really need are the LG<model>_DLL.msi files. Specifically, I need it for the RS988. It was listed in the supported devices at the beginning, but can't find it =(

When you open "Settings" -> "General" tab -> "About phone" -> "Hardware info" what does it have for "Model number?"

Model number: LG-H850

OK looking at the screenshot, I'm wondering if somehow the install got messed up. If you go to:
c:\program files (x86)\LG Electronics\LGUP\Model
What are the contents?
Also, open powershell as an administrator (usually can just type "powershell" from an elevated command prompt) and run this command:
Get-ChildItem -recurse 'HKCU:\Software\LG Electronics\LGUP' | where-object { $_.Property -like "DLL*"}
Then copy/paste the results so I can see them =)
In regedit, go to:
HKCU:\software\LG Electronics\LGUP\Model

Contents is (screen A and B).
Question. They must be unlocked bootloader?
Because my LGG5 be unblocked (Demo Unit).

You should be able to use the LGUP tool regardless of whether or not you have an unlocked bootloader. You may not be able to flash every kind of *.tot file, but whether or not your phone's bootloader is unlocked will have nothing to do with that error you're getting.
What about the output of the powershell command:
Get-ChildItem -recurse 'HKCU:\Software\LG Electronics\LGUP' | where-object { $_.Property -like "DLL*"}
?

Here is the result Powershell command:

OK, so, do the following, and then try to run LGUP with the phone connected, and let's see if it works:
1. Create a blank notepad file
2. Save it as something like h850.reg to your desktop where you can find it easily.
3. With the file still open in notepad, copy/paste the info below info and then save it again.
4. Close the file, then double-click it from your desktop to import it.
I've also attached it as a *.txt file which you can just change the extension to *.reg if that's easier:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\LG Electronics\LGUP\Model\H850]
"MODEL_NAME"="H850"
"DLL_PATH"="C:\\Program Files (x86)\\LG Electronics\\LGUP\\Model\\H830\\LGUP_H830.dll"

How Do I Downgrade The LG G6 H873 From Android 9 to Android 7.1/7.0?

Hey. I'd like to downgrade my LG G6 H873 from Android 9, to Android 7.1/7. I've been thinking about factory resetting my phone for a few reasons, and, coincidentally, I have been thinking about rolling back to Android 7/7.1 for more RAM storage, where it is recommended to factory reset the phone before doing so, which would kill two birds with one stone. So: can I? I understand that the boot-loader is locked, which, unfortunately, kills the option of rooting, but I'd like to know if it is possible to rollback, and, if I can: what are the steps to doing so? A response will be greatly appreciated. Thank you for reading.
