It would help if you were more specific about what you are trying to do.
With that said, are you talking a stock kdz or a rooted system image? If a rooted system image you can do it with TWRP-in-FiSH, provided you can obtain the one you want from a member who provides his own TWRP-in-FiSH system image backup but you can't do a stock KDZ. Cross-flashing any different model firmwares, at this stage (until steadfasterX completes and publishes his boot loader unlock process), runs a high risk of a hard brick.

Hi Sdembiske, I read about the unnofficial bootloader unlock: https://forum.xda-developers.com/g4/general/bl-unlock-unlock-bootloader-proof-t3648288 and it seems H812 is not fully tested yet (see Proofs section). I'm not brave enough to try it on my phone until it has been fully tested. I know if everyone thought like me, there would be no progress.. :laugh:. Thank god theres some brave people out there....

Thx. I was provided a tot of genysys with Twrpinfish injected. Just thought there might be a way. Also, itd be neat to flash my kdz or tot from the device

Thx to @the_naxhoo for this tot
Also there seems to be easy ways to edit a kdz with hex editors apps than winhex for example, which requires a hefty priced pro add-on. BTW I've flashed different region kdz with LGUP without issues.

Being able to flash different region kdz's is very Model specific - e.g. H815 International/Europe version plus a very limited number of other models and only one or two with locked bootloaders (most of which have issues from what I can tell). Some models, like the H812 are locked up tighter, running a very high risk of hard bricks screwing around with other model/region firmware flashing- So again, you have to be specific.

Apologies. I own a H815T and have flashed H815 kdz's , so my question is- if there is any way to zip a kdz for flashing, extract correct partitions for the zip , edit the kdz for flashing from the device etc, i think it would be a pretty handy tool
Just a thought.

Once steadfasterx releases his unofficial bootloader unlock you can flash any g4 variants firnware and even better, custom roms. Just hang in there man...its coming soon

Check out steadfasterX's SALT: https://forum.xda-developers.com/g4/general/tool-salt-lg-revolution-t3717864
Has some of what you're looking for now and will eventually, when completed, be able to flash what you need.

Thanks mates

Sorry if I'm asking in the wrong place but I followed your guide to bullet proof method to get started with SALT - FWUL 2.5 persistent.
I get to the welcome screen but when I press enter on 'FWUL 2.5 persistent' it says no such directory.
I have chosen -linux ,arch linux32bit (64bit wasn't available on my laptop) after following steps to create the .vdi drive in VirtualBox directory

Nevermind ,I had to use x64 arch Linux.

We should move this over to the FWUL thread.
First, confirm you have downloaded only from this location in the FWUL OP for the persistent versions (my concern here is that you have downloaded a forgetful version):
https://androidfilehost.com/?w=files&flid=214529
Make sure you are running the latest version of (Windows) VirtualBox and that you have installed the Extension Pack as well.
Even if your Windows PC/laptop is 32bit, the VirtualBox drop-down menu should allow you, in the 'New' setup menu, to select Linux and under that entry, the 64bit Arch Linux OS (it should be right above or below the 32bit version in the drop-down menu) - that is what FWUL is based on ... i.e., it doesn't matter that your PC/laptop is 32bit.
Ensure you are matching your .img file name in the conversion command exactly to the persistent .img file name you downloaded, extracted and moved over to the VirtualBox original install folder to run the conversion command. Copying and pasting the conversion command from my post, is the most error free way to do it, provided the file name matches exactly to the .img file you downloaded.
Important: Insure you have enough available hard drive space on you PC/laptop to install the size of FWUL .vdi disk you created, in addition to the .img file you downloaded.
Check the following two locations on your PC/Laptop hard drive for the .vdi file you created from the conversion command.
C:\Users\Your_User_Name\VirtualBoxVMS
C:\Users\Your_User_Name\AppData\Local\VirtualStore\Program Files\Oracle\VirtualBox\
If you need to try again, remove the FWUL install and delete all FWUL related files - double check the two file locations above to make sure there are no FWUL related files there whatsoever.
Any further questions, please post to the FWUL thread.

Thanks dude. It worked :good:

No problem. I can probably use the troubleshooting guide I prepared for you again on the FWUL thread.
Glad it worked - had me concerned there for a bit as I thought I laid everything out pretty succinctly in my original post, to avoid errors.
Enjoy - particularly when steadfasterX completes the full-meal-deal.

One question. How may hours does it take to do a full backup in salt?
I don't mean to be rude, but its been like 3 hours..

Sorry , took a basic backup but it failed verification. I'll have to do some reading
epescially when trying out the usu unlock feature!!!!

Downgrade from MM to LL with LGUP is possible!

Just wanted everybody to know that you CAN downgrade your MM LG G4 for Verizon by using LGUP.
And this is how...
1). Download all The Files Below!
1) Firmware Files - Click HERE!
Or Here LGKDZ.com for your exact match KDZ for your model
2) Download LG Drivers - LG Drivers Here - 10.9 Mb
2.1)Verizon Drivers (Verizon Only)LG_VZW - 7.8 Mb
3..LGUP can be found on this website LG UP DOWNOAD
You have to sign into one of your accounts and like the page for them to open the downloads in the middle of the page.
4. install the drivers then the .msi file for LGUP. Usually there is a DLL file and the LGUP application, install the .DLL file then install LGUP.
5. First make sure that your phone is showing up on LGUP, if not make sure you have USB debugging enabled and the you are connected with MTP.
6. Find your .kdz file, and don't press start VERY IMPORTANT!!, Exit out of the application and then REOPEN LGUP and your 13b.KDZ should still be in the box at the bottom.
7. Now just press start and wait for it to do it's magic.
And now your back on LL and you can get back to rooting this phone.
And just so people know it is not possible to downgrade from LL to KK, it will brick your phone for some reason, and trust me I had to send mine back and get a knew one, nothing would get it to work again!
So that's how you get back to LL from MM, which seems to be the only way to have root at the moment...
One more thing, I was able to transfer the files for the effortless root on MM but you can't do any send_command.exe commands because it just says FAIL. but it did switch the system software from Official to Modified so it did something just not what I wanted it to do....
If there's anyone wondering why this works, it's because both the 13b and 24c kdz's both have the same qfuse number, so the bootloader accepts both without bricking. If Verizon ever puts out an update that increments the qfuse value and you take it, you won't be able to downgrade to 13b or 24c.
I have the kdz file but it wont let me put it on lgup. It's looking for a .tot file. Help would be greatly appreciated
Nevermind. Figured it out
would this work with h811

Thank you for the info! Just curious: how do you check the value of qfuse?
I did this on a Canadian variant H812 and it worked. Rooted right after and that worked too. I am a happy camper.
I loaded H81210n.
Anyone reading do note that I did not use the Verizon files above.

What you must do is tick the update and select the kdz file. Then close LGUP, open it again and select refurbish and kdz file should be there. Start the load.
This phone with L and root is perfect. No M for me until root (if it happens). Really enjoy having the changed DPI with root and no permanent notification for Priority mode.

*edit* sorry did not mean to quote the person above me. I'm asking about actually getting from MM back to LP
Hate to ask this but has anyone verified this? I'm wanting to do this to mine tonight but I don't have near the experience a lot of others do here.

I haven't done it just yet. And I know I'm not the smartest here. But to my knowledge yes you will lose everything. So always good to back up all your files. I've got all my photos backed up to google photos. over 5000 lol. But yeah from what I understand it's the same as doing a factory reset except instead of factory resetting back to MM you're factory resetting to LP.

OK, I did mine last night and using the refurbish mode as said does in fact delete all data.
((TO MODERATOR CAN WE GET THE ORIGINAL POST UPDATED TO INCLUDE THAT TO LOCATE THE KDZ FILE YOU NEED TO FIRST TICK THE UPGRADE CIRCLE)) I found it down the thread, But just figured it would be easier for others if it was included in the original post. Thanks
Big ups to everyone who made this happen!

Hey sorry but the www.lgkdz.com doesn't work. Is there another site we can find all lg firmware to downgrade for our exact lg variant match....
From OP second 1), try : http://storagecow.eu/index.php?dir=Xda/LG+G4/
or check the XDA G4 section for your variant.
Thank you for your response. I did actually download the H812 kdz from storagecow however when I put it in the LGUP tool it read as an error in the tot file. I'm not sure what happened or where I went wrong. I'm so confused at this point and without my G4 being unuseable at this time. I also wanted to ask if the kdz you directed me to are in fact the file I need to go back to LP from MM?

LGUP Oreo DLL File for V30

I had this issue last night so thought id save people some trouble and share the the file needed incase you need to flash over 20D's KDZ file either to go back or forward.
Please unzip and put in C:\Program Files (x86)\LG Electronics\LGUP\model\common
Works with LGUP 1.14

Damn.
I had it working with 1.14, but I thought I had the wrong version. So I uninstalled it.
Now I can't get it to load - wrong dll for VS99620a.
Plus I wanted the developer version of LGUP.
Pretty sure I need the Partition option to flash other-model KDZ.
Hi there,
I need some help because i fell so stupid.... I cannot use the patched DLL for uppercut in order to flash the newest Oreo KDZ for H930...
I installed LGUP 1.14, USB DRiervs, etc... Download and uncompress uppercut 1.0.0.0. I downloaded the patched DLL 1.0.31.9. Even if I copy that dll on the uppercut folder or wherever i copy, the version shown on LGUP is always the 1.0.28.9... SO I cannot flash the latest Oreo KDZ
Help please?
thx in advance
you have to run lgup.exe not uppercut shortcut.

Hi, has anyone been able to revert back to N from O, please? I upgraded my H930DS (Hong Kong) to the Open Euro 20d ROM, but haven't been able to go back to N using either the patched LGUP or UPPERCUT (… I'm not happy with the limitation on the use of the dual SIM). With the phone in download mode, the error I get is "DLL for H93020d is invalid. Please install valid DLL package(*.msi) for the model". I get the same message if I try both methods with the phone in its normal operating mode. Thanks for any help.

Thanks, but I think the operative word in that quote is "should". I've tried that method with the phone in download mode and with it in its normal operating mode, but LGUP no longer recognises my phone model. I can get the LGUP pop-up with the serial port but the pop-up shows the phone as an unknown model, which I guess is the issue preventing the firmware update.

Here is the reply I received from LG about reverting to Nougat (I asked them to do it for a fee):
"Dear Peter,
Thank you for contacting LG Customer Support. I apologise, but please be advised that we cannot put back your the previous software of your phone.
We suggest that you perform Factory Reset to your phone. This will not restore its previous software, but can fix issues of your phone. However, this will delete everything saved in your phone memory. You may back up first your files.
To reset:
Go to Settings
Select Backup & Reset
Select Factory Data Reset
If the issue will still continue, please let us know so we can assist you further.
Thank you. Have a great day ahead.

… However, I was able to flash my LGH930DS to Oreo for the LGH930DS using LG Bridge after a few attempts (I couldn't get UPPERCUT to revert my phone to Nougat), resolving my issue with using the dual-SIM with the cross-flashed firmware and thus obviating my need to revert to Nougat.
Looking for some guidance please & thanks.
I have a H933, converted using the Frankenstein method to a US998. Then Unlocked BL, TWRP and rooted. Upgraded to US99820d
I would now like to flash back to stock H933. I have installed the Patched version of LGUP. I have extracted the DLL here into a common folder inside the model folder. I put the phone in Download mode, plug it in and then launch LGUP (patched). it finds the device but then errors saying the DLL is not valid for US98820d and to get a compatible DLL.

H810 10o MM kdz or modem img

Hi I successfully unlocked by UsU thanks to steadfasterx. But I overlook the q&a and that was I must be on MM before unlocking....ahhhh I was on L.P.. I'm now searching for mm kdz for h810 10o. If anyone have pls share. Twrp successfully installed. Gpt compatability is h811. Arb is 2.

You will have to extract in SALT to determine whether arb 2.
Thanks for reply and links. I've already try this file as described in thread. OTA starts and phone reboots into TWRP., don't know what to do from here. Luckily u gave me an idea to check in SALT. Do i rename the file as .kdz? Meantime i'll try it as kdz in salt.

OK, sorry I didn't download and extract it. Doesn't look like a complete kdz file. Do not use that thread process or any other app other than SALT to extract a proper kdz file to get the mm modem image.
I would then, in that case, google search for:
LG H81020 KDZ
with a version letter closest to o, e.g., LG H81020p; LGH81020q ... etc.
and then extract in ONLY SALT to determine whether arb 2.
Ok thanks i'll try to find one and post the results afterwards.

first of all - great job steadfasterX and cWks! with unlocking LG G4
probably I bought (in China) "Frankenstein" LG G4 phone, because it should be H810, but on mainboard is written VS986. I have unlocked it by SALT and instaled TWRP, but I have not find any ROM which would work
based on the information from the vendor it should have V10o ATT firmawe, but in the LG software it shows that is model H815 with firmware V29a.
subsequently I brick it and unbrick it a try to fash .tot files using LG software, but unsuccessful. Because the LGUp shows, that it is model LS991 finally I flash the LS991ZVD.tot file. during booting, the android will stop, when "configuring your phone", probably LS991 files have wrong modem...
now works the download mode and recovery mode only for this phone (no fastboot) and in SALT shows that is ARB4 which is not possible to unlock
Is there any possibility to:
1. to flash correct modem (possibly for VS986?) - 1.a) how is possible to modify the modem in tot file?
2. erase eMMC or go back to ARB2?
I have the backup prepared in TWRP with ARB2, but how us it to recover the phone?
Many, many, many thanks for help!
Or it is easier to buy in Chine the new motherboard? and which?
Thank you very much for answers!!!

Ok well first of all read my signature about the anti roll back details. It is absolutely impossible to flash lower ARB . That's for what it is made for obviously .
Next is that you have flashed stupid files and besides they're with an arb higher than 2 so you cannot unlock it anymore.
we all know that Frankenstein devices are special in many terms .
one example is nobody knows what they do or flash in the primary boot loader which we cannot read out. That means we don't know which RAM is compatible and we do not know if they make any modifications in the signed boot loader stack which ensure they can load Frankenstein devices.
So even if you flash for example h810 files with an arb of 4 it may not load or working properly the same goes for vs 986 of course .
yeah and I have to repeat myself but flashing that arb of 4 was bad in another way,too. Having that arb you have no way to use qfil anymore as that works only up to arb 3. So you have no way to use it to flash for example other models image files or even more important to unbrick your device if it ever hard bricks.
You can of course use a text editor to modify any kdz file and flash whatever you like .. The other option is to use the SD card unbrick method linked in my signature but it requires to hard brick your device first. I can tell you how but in your situation it is very risky if you can't get the SD card unbrick working . so I would recommend to go the Hex editor way just search XDA for how to use it and flash vs986 files with an ARB of 4

You are right. I have done some stupid steps, because the method for unlocking my "Frankenstein" phone did not work. I read about the anti roll back, but I hoped that something had changed (also the unlocking process has gradually developed )
I had to take apart the phone first and find out what was written on the motherboard This was a big mistake!
Today I have bricked (hard?) my phone by flashing LS991 ZVB ARB3 tot file, because I don't know, how to work with Hex editor.
Which KDZ file I need to download for SD card unbrick? I suppose that VS986 with ARB4, right?
Thanks for a help and reply!

well I see. the ARB is (as written in the linked guide) a (extreme likely) physical blown fuse, so a process which can not be reverted..
yes you hard-bricked the phone by flashing a lower ARB then the current one. once you flashed ARB 4 you can't flash ARB lower then 4.
the good is as you have hard-bricked it you may be able to use the sdcard unbrick but that requires the 9008 qdl mode:
connect the device to your PC and view the device manager. does it add something like QHUSB BULK? If yes use the vs986 files + UsU files as written the sdcard thread.
You can also use FWUL from booting on USB and just type: lsusb in a terminal after connecting the phone. paste the output here then. It should show something like "QDL 9008" or "QualComm...". If thats the case use the vs986 files + UsU files as written in the sdcard thread.
If both of the above does not show up the QDL 9008 mode.. well try it without battery in again. If it still failing it is likely gone. sorry. The QFIL files available do not work with ARB >3 so.
You can still read on in the sdcard unbrick thread in the second post to find out how to force the sdcard unbrick mode (that differs from the the QDL mode and so need to disassembling the whole mainboard and doing tricky stuff without a guarantee of that it work at the end.)

Yes, Q HS-USB QDLoader 9008 is in the Ports (in DevMan), but now I need to prepare SD card, because the old files (which I have used for unbricking last time) do not work .

I don´t find the right kdz for VS986 with ARB4. Can I use yours? (these two with ARB2: http://leech.binbash.it:8008/stock/LG/vs986/2BA/)

well you still do not read my linked guide or understand what ARB is, right? Its IMPOSSIBLE to use an ARB lower then 4 in your case. so NO you can NOT use these.
Well I assumed there would be firmware with ARB 4 for the vs986 but it seems the highest is ARB 2..
keep in mind: everything you do now is extremely risky with maybe no point of return! If it bricks and is not switching to the 9008 mode.. you are lost!
After looking around a bit including in my ARB thread (which I mentioned) the LS991 seems to be the only one with ARB higher then 3 (so 4).
you are stuck with LS991 now. that means even when you may be able to unbrick with the sdcard unbrick it means you may never get cell service.
so try a LS991 kdz with ARB 4 (ZVD as you flashed that one should be fine) for the unbrick files to bring it at least back to life.

OK, so we understood each other. Because I flashed wrong file LS991 ZVD, I can't go back - only to the same firmware (because of ARB etc.). There is no way to change it (to VS986) or flash anything else
and, if I will be lucky, then the phone comes back to point during booting, when it stops in "configuring your phone". Never use him anymore for call services? How to go through this (configuration)?
There is only one way - to buy in Chine the new motherboard, but which (H815)?

buy a h811 one as you can unlock h811 within just fastboot.
if you can't get one: the h815 international (so no h815p, h815tr etc) as it can be unlocked officially by the LG website.
if you can't get one: any h815 model should be fine as you can unlock by UsU and I haven't heard any big issues here.
good luck

OK, I understand.
Could you be so kind and send me a link for kdz file? I don't find it. I have only LS991 ZVD tot file. It is possible to convert it to kdz?
Thank you!
I have prepared the SD card from tot file (not bin but img files) except PrimaryGPT.gpt (I don't fin it in tot file, only the PrimaryGPT_0.bin from another KDZ).
The proper KDZ for LS991 ZVD I could not download from LG support site, because my FR phone has IMEI VS986.
Until now the SD card unbricking method doesn't work for me.
I will try LS991 ZVB, which I used for bricking the phone.
Any idea what to do?

Lg G8 AT&T full firmware backup file

Please can someone help me with their full firmware backup so I could restore mine. I mistakenly wiped both slot A / B and now my phone won't boot up. I just bought the phone and to my surprise AT & T doesn't work in Europe.

No still hoping someone would upload it.
Guys just crossflash with lgup, somewhere on XDA are instructions. Then at least the phone would be working.
It won't work I have tried it except you know another way. It's lock to AT&T America.
Hi I came by this post about an LG g8 att model. So I have such model and going to wipe it and flash a custom rom on it.
Perhaps before I do that I can put the original file here. Can someone guide me and point me to the proper page to do this?

Another utility to use for backup and flashing back would be the bkerler edl python utilities.
Search for it and you'll find his github page, and on it, he even provides a bootable image you can flash to a usb drive, boot it and it's ubuntu with all the utilities and all dependencies resolved.
I've used them many times and it's the first thing I do is use them to backup original rom on the device. Sorry, don't have at&t, just sprint.
Keep in mind there are some partitions you NEVER want to flash from someones backup, they contain imei and s/n.

Does anyone have firmware for ATT G8?
So I tried many ways, as an unexperieced rom flasher, and so far had no luck.
The LG G8 ATT phone doenst even want to boot into recovery mode.
Also connected to a PC via USB and entered some commands via ADB tools and even then it will just reboot the phone.
Anyone got a clue what I am doing wrong?
