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.

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?

How far back did you come from? Were you on the most recent version up to that point?
Thinking of finally abandoning 13B with the inability to tether reliably (bizarrely). Wi-Fi calling would be a good feature to have, anyway.

Is there information anywhere about which versions are safe to 'Upgrade' to which?
In other words, from 13B do I have to KDZ to 24C to do an 'upgrade' before going to 26A or higher?
Or can 13B fly straight to 27C or 26A with an 'Upgrade'?
I've been reading for hours and can't find folks claiming which versions they were on previously when they went to MM from 13B.

When it comes to upgrading you can go straight to the latest. But be sure you choose referbish so it wipes the device. Not Wiping can cause issues. But you should be able to update your device via OTA or the Verizon software assistant as long as your not rooted. But remember you may not be able to downgrade once you go MM

I couldn't find a back-to-stock guide myself (and when I got to stock 13B, verizon updates seem to fail for some reason anyway) - but I just used the basic KDZ instructions.
https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
I got the 13B image from the links floating around. I guess I'm going to use the same links to get 24c and 26c and 27c on the phone. Weird that updates won't work, although I do recall going to great lengths (before doing the KDZ) to make sure automatic updates don't go.
Edit: Also, everyone should be aware:
Every new firmware (including the new 29C that came out yesterday) seem to be available here:
https://lg-firmwares.com/lg-vs986-firmwares/#comment-539
I can't verify the legitimacy of them other than that I just downloaded 29C and we'll see how she rolls.

Anything we can do to help with rooting this 27c or 29c kids file ? I just got a g4 vs986 27c, and am still reading up about it... What is the kdz, like our version of a .img file that most other Androids use?
Can't we just unpack the file, change permissions and settings then repack it & flash it like any other update?

No. Kdz files are official files from LG. They can't be changed in anyway.

You can unpack it. But you won't be able to repackage it back into a flashable kdz format. You'd be able to turn it into a tot file though.

Well ok then we're in business... We unpack the kdz, root the os files inside, then push all the files into the phone.... Yeah?

D85130g Downgrade can it be done or not

About to buy this phone and am getting mixed answers reading through the threads. Can the latest build (D85130g) be downgraded or will I get an error with the flash tool. Don't want to spend the money and be stuck on stock. I know kingo only works with earlier firmware.

Yes you Can.

Obviously. It's 3 years old. That being said, some of us are broke af and are buying it for the good specs. Despite the age

It still do the job well if hardware not failing. If you root it and put new software on it work as new so its very good.

I actually ended up buying it after confirming it could be downgraded. Ran lineage for a few days but despite being fast, was a little buggy for me. Currently running the stock 30g rom and aside from the crappy battery life, i have no complaints. This phone was definitely advanced for its time and gives new phones a run for their money. This phone is solid. 80$ well spent imo

I've been trying for 2 days to downgrade my G3 D851 and it will not flash using LGup or LG Flash tool 2014. The process starts, but always stops due to error. LGUP always shows Unknown Device [COM41, D85130e]. Have set port to 41 and random. Can anyone offer any solutions? Have tried tot and kdz.

i believe the flash tool I'm using is from this thread(https://forum.xda-developers.com/tmobile-lg-g3/general/firmware-t-mobile-lg-g3-t2818667) under "kdz flashing method". Using a stock 30D kdz from one of these threads. I don't set the port to anything. Never fails for me. If it doesn't work I'll zip the exact one i have and upload when i get home. Where is it failing? What percentage?

Thanks. I finally succeeded with LGUP. Turned out when I downloaded and installed LGUP, it came with 8994 dll, and the D851 requires 8974 dll. It still didn't work with KDZ, but I got it to work with TOT. What a PITA!!! I don't envy anyone else trying to root D85130e without advanced knowledge. Thanks for your offer to help. Maybe this will help someone else that is having problems. The LGUP download with the 8974 dll is here. http://oceanhost.eu/545euinlq0hw/LGUP_LG_G3.zip.htm

Maybe this will help someone else that is having problems. The LGUP download with the 8974 dll is here. http://oceanhost.eu/545euinlq0hw/LGUP_LG_G3.zip.htm

Good luck to you. I was able to root with stump root after flashing this.

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

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.
