Solution: Downgrade from MM to LP by using lg up

first of all i want to say that i already seen similiar thread like mine but it is all about using tot method but my thread is all about lg up .
First of all it"s not my work,full credit goes to autoprime. On autoprime thread in the first page i dont see the updated dll file,he gives the update few page later. So i think people face problem during downgrade like me, So thats why i am opening this thread but if moderator thinks its not nedded, please delete this thread.
so here are the Steps
download kdz for your phone from here http://lg-firmware-rom.com/
install dll file from attachement
installing lg up and how to connect your phone...follow the instruction from here http://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
make sure you install dll file before lg up.
Open LGUP on your computer, click on upgrade and point it towards your LP KDZ. Close LGUP and re-open LGUP and select refubrish.. Make sure you select REFURBISH this will do a full wipe, tick BIN file. Press Start. Now you are done and hope it helps people, who are face trouble during downgrade like me also don't forget to hit thanks if it's helpful to you.

OMG I LOVE YOU... I've tried everything, almost lost all hope, thank you thank you thank you! Works like a charm!

OMG! you're the man! All this time, i've been installing the LGUP before the dll. no one said it's the other way round. Thanks a ton!

How do I register the DLL file? I am running Windows 7 64-bit and I get this error when trying to register using regsvr32 in both system32 and syswow64 folder.
The module "LGVS985_20140620_LGFLASHv160.dll" was loaded but the entry-point DllRegisterServer was not found. Make sure that "LGVS985_20140620_LGFLASHv160.dll" is a valid DLL or OCX file and then try again.

Thank you for your help, much appreciated. I have been running into this problem when trying to refurbish 47a or 48a. When LGUP is waiting 120 seconds for restart (about 80% in LGUP), my phone just keep restarting without completing the installation. It keeps bootlooping and then LGUP keeps waiting for my phone to restart. LGUP will say 100% but my phone is just bootlooping constantly.

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.

(Request to a moderator below my response to stephen293)
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 shows unknown model ????

Hi Guys i have LG G3 D851 ..i am currently on MM i want to downgrade to lollipop so i downloaded the kdz file V20e but the problem is that LGUP cannot detect my G3 shows the device as unknown model but correctly shows the comports i even tried using LGFlash tool used seems that i cannot downgrade shows error and stops so i wanna know is there any way to fix this unknown model in LGUP ...

Guess no one wants to help here ?? To anyone else who has this issue u may need to change the buildprop file and ur phone must be rooted it still doesnt shows as unknown in LGUP but since i have rooted my phone n bought a new battery and installed xposed and im having a good battery life i still want to know why it aint showing up in LGUP

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:

LG G4 H812 & H810 - External SD-Card fails to mount in both phones

I jumped into LG G4 wagon and got these two phones- first H812 Canadian variant (rooted H81210n) and second H810 AT&T (non-rooted locked H81021y).
External-SD-Card fails to mount.... how is ext-sd mount activated , assuming that its a software Linux mount problem and not hardware???
LG firmware has special external sd-card permissions??
Any tool(s) or apk to activate or check the mount and read status within LG Firmwares??
Very perplexed!!
HELP Please!!

IF, your SD card for the H81210n is formatted exfat, that is likely the problem, if so, check out the Addendum in this post: https://forum.xda-developers.com/showpost.php?p=73250389&postcount=37
All install files are linked there.
If the same applies to the H810, it may be a similar issue - you can try the same exfatfs.ko linked there - I don't see any downside to trying it but if it doesn't work, ask a member to upload and link the the appropriate exfatfs.ko for the H81210.
If not exfat formatted, this will give you an idea in file manager to start looking for the issue, i.e. /lib/modules .ko files.

Still no love from G4-H812 and G4-H810 with Mount

Thanks for replying.
I did try moving exfatfs.ko using ES File Explorer with root permission on.... but alas, still no love on H812.... mount just does not get activated..... (exfat or fat32) I am confused ... maybe other *.ko files are corrupted or can its kernel mount config / permission issues still??
for H810-- I am using stock locked H81021y, so could not get to write system file unless I find a rooted image to flash.

Here is list of kernel modules I have on H812

I would start by getting a copy of the kdz version for your carrier, extracting it and then copying all the files you copied from the zip provided in that post back to your H812. Any files that were copied from that post that are not in your extracted kdz I would try and delete from your phone.

I know my big mistake.
I read I can use UsU now?? I updated FWUL/SALT today under VM Windows 10.
Seems like I have to update TWRPinFish version too. Let me try that or Can UsU will update all- twrp, all base system files for G4??
Little summary of steps to follow would be helpful.. if you dont mind, as I get confused reading so much happened while I lost interest/time to update and get H812 working again.

What you need to do, IMO, before UsU, is to try and flash the LG Lollipop stock kdz for your carrier in LGUP-NEW and then upgrade to the the stock Marshmallow kdz for your carrier. You will have fewer problems if you can get your stock MM kdz on your phone before proceeding to unlock your bootloader ...

Yes, it's not a problem - I did it many times but I would suggest if you're on a rooted LP 'H' version you flash the stock 'H' version (with LGUP-NEW) - if on a rooted LP 'N' version flash that one ... then upgrade to MM with LG Bridge. Then back up the MM stock rom in SALT and proceed to the UsU bootloader unlock procedure ...

Okay.. I did try stock KDZ LP / MM .... still audio and camera does not work on H812, in addition to external-SD fail ... will UsU help in sorting these issues when it unlocks ?? Seems like this phone is behaving like as rigid as donkey...
Will UsU load all necessary files on its own using SALT/FWUL under VM?
I was tempted to flash H815T to test.. but I didn't. :fingers-crossed: seems like some system files are registered and locked in bootloader or somewhere else. makes me wonder if TOT is fuller than KDZ and maybe posted h812 kdz versions are not complete in itself ?? oh well....hope UsU helps resolve those issues. Please highlight steps if I need to download supplementary files before using UsU under SALT.

- Did you first flash your Lollipop rom in LGUP-NEW, as I suggested, before upgrading to Marshmallow? I think you should try and solve these issues you are facing before proceeding to unlock. I strongly suggest now that you read through thoroughly the OP in the [UNLOCK][UNOFFICIAL][G4] Unlock **ANY** LG G4 device with UsU thread and post exactly how you messed up your phone so steadfasterX can advise and hopefully help you solve. He will be the one to indicate whether you can or should proceed to unlock.
- read the OP thoroughly in the bootloader unlock thread (refernced above) and make sure you understand it fully to answer your 2nd question.
- If you flash ANY H815 rom you will brick your device. In SALT, the GPT compatibility should show as H811 but do not fash anything else now until you get help from steadfasterX. Post on his threads, please, from this point on ...

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

Do you happen to have a link to LGUP 1.4? I can only find 1.14.3.
Thanks

Interesting. Looks like they updated the KDZ format again.
*Sigh*

1.14 is the latest. I found some other typos in other LG threads also calling it "1.4".
Sent via open market LG US998 V30/V30+

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.

My bad my folders in setting was hidden

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.

Yes. I saw a report yesterday of someone who had downgraded. Just flash the KDZ:

to downgrade just use the new oreo lgup_common.dll and you should be able to flash previous N KDZs again in LGUP.

ROM or the KDZ? You probably mean the stock open European KDZ.
For the KDZ, go to the thread. Instructions are there.

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.
The version of LGUP_common.dll that I'm using is 1.0.35.3, which should be the latest. Its digital signature is dated ‎Tuesday, ‎19 ‎December ‎2017 3:33:29 PM. Its MD5# is c3df15812c1294028bfd330eb725519b.

i doesn't work for me on my ls998 v30+ sprint. do i need to make new folder (common) in the model folder? i tried with and without...

Looks like there's no going back...

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.
