Reverting LG G7 G710EMW to Stock Oreo - LG G7 ThinQ Questions & Answers

I have an original LG G7 G710EMW completely untouched, updated to Pie and not impressed with more apps no longer working. I've never rooted etc, what's the correct way to downgrade to Oreo from early this year?
I found this
https://lg-firmwares.com/downloads-file/16711/G710EMW10i_00_0924.kdz
I'm in AUstralia
Not sure if I have to unlock something to downgrade back.
Also when they say backup your stuff, since everything is in my google account I only need to save DCIM folder right?
Do I need something to save call history/sms?

[Q] [D855] branding regardless of ROM

Broke my Nexus 5 display and the insurance replaced it with a G3 (because the Nexus is out of production). So, things are a little different here from what I can see.
First off: Branding and Bloatware. New things for me coming from the Nexus family. There, I only needed for flash YAKJU over TAKJU (or something like that - was a long time ago) for the Nexus 4 and you were completely in LGs hands regarding updates. No other intermediaries or stains from other carriers. The G3 being a Vodafone terminal it had a lot of branding.
To get rid of branding I went ahead and rolled back to v10f, rooted and deleted the /data/.OP/VDF folder (after backing it up of course). Then updated to v20h. The result? Stock LG boot, sound, no VDF apps.
A couple of things remain though:
- the software version is V20h-226-01 . Why 226 and not EUR like I saw around here? Doesn't matter which stock ROM I put on it (bumped stock ROM). It still adds 226.
- default language is my native language from the start (Romanian). Why? Shouldn't it be English?
- still, the update center tells me I can install 18 apps, all Vodafone crapware.
I guess my question is, how can I get a pure international D855 without any carrier involvement? Is it even possible?
Thanks in advance.
You could roll back to kitkat, root, install TWRP, then flash a rooted version of stock lollipop. Should be the generic one. Personally, I use cloudy g3, which is still on 20F I believe, but if you want a 20H stock, try http://forum.xda-developers.com/lg-g3/development/stock-t2961073
That is the one I installed and that is the procedure I used to be rooted, bumped and lollipoped.
Doesn't matter, still v20h-226-01 appears, still VDF apps in LG update center bugging me to install them.

If you can get by with just not seeing the notification, just long click the notification, hit app info, and untick show notifications. Not exactly the solution you may want but at least it won't be an eye sore.

Understanding the correct KDZ file, help!

Hi,
I purchased the phone in the UK from the network carrier Vodafone. I have done a fair bit of research on the rooting and unrooting process mainly via videos and reading tutorials on XDA.
I would like to root the phone and gain super user access and install some Xposed modules but would also like to be able to unroot and flash back to a stock Vodafone firmware encase I need to claim under warranty. I have been trolling the internet to get the correct KDZ file and found this site (ttp://devtester.ro/projects/lg-firmwares/country.php?country=United+Kingdom). I believe that the correct firmware may be on here but am a little confused on what the suffix and software version means to be honest.
The reason for my confusion is that I updated the firmware to 6.0 Marshmallow through the LG bridge but when I now check my phones software version it states v20b-234-15. I assume this is right but from memory the first software version when I got the phone was something like H81510B_00.
I cant remember exactly what it was before unfortunately but the KDZ files I have found state H81510C_00 (Suffix - AVDFVK) and H81510C_00 (AVDFLR) and this does seem to make sense but I'm thinking it was B instead of C but and not 100% on that.
Do you think these KDZ files would be the correct one to flash back to encase I run in to some problems rooting?
I am also assuming that this KDZ is Android Lollipop and not Marshmallow so is it OK to use this to revert back from Marshmallow?
Thanks and any help would be much appreciated.

The 10X version are all Lollipop, 20X is marshmallow.
When flashing a KDZ on your phone, what's important is what model your phone is. H815 in your case.
If you want to restore to stock in case something goes wrong, you can find everything here: http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
In there is a link to this directory: http://storagecow.eu/index.php?dir=Xda/LG+G4/ where you find pretty much all KDZ files for G4 phones.
I'm not that experienced myself, but I rooted my phone just recently and I can share my experience with you.
I have a H815. It was a V10c-TWN-XX version (Taiwan). I updated to Marshmallow with LG Bridge also and the new software version was V20b-TWN-XX.
Marshmallow rooting is not possible on my phone because I can't unlock the bootloader on it. And Marshmallow rooting is only possible with an unlocked bootloader. Unlocking the bootloader is only possible on European phones (http://developer.lge.com/resource/mobile/RetrieveBootloader.dev?categoryTypeCode=ANRS). I asked autoprime (renown user and developer here) if I can unlock bootloader after flashing an European KDZ on it. He said no, having European software on it is not enough, it has to be a phone manufactured for the european market. Dont know why, guess because of different hardware.
So, not being able to root MM, I had to revert back to stock (downgrade) using one of the KDZs.
I chose the most recent one in the directory I linked (which is the Poland H81510E). In the "Go Back to Stock" thread I linked the OP says to use LG Flash Tool 2014, which unfortunately doesn't work with Marshmallow. But fret not, it works with LG UP! http://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
When I tried flashing the KDZ with Flash Tool 2014, the process failed with an error at 5%. It worked flawlessly with LG UP. Here's more information regarding downgrading, but it really isnt hard. Just download + install LG UP. Launch it. Connect your phone. Choose KDZ file. Select option "upgrade". Hit start.
NOTE: after the firmware update was done, the phone rebooted automatically and for me it stuck at at the LG Logo (bootloop). But a simple hard factory reset did it, the phone booted and my new version was 10e-something. With Lollipop 5.1 of course.
After that, I rooted my phone using this pre-rooted image: http://forum.xda-developers.com/g4/development/h815-eu-l-p-t-sea-twn-t3176195
and this guide: http://forum.xda-developers.com/g4/...-tmo-vzw-intl-variants-soon-root-lg-t3164765/
I now have a "H81510e-EUR-XX" Lollipop 5.1 with root (SuperSU 2.49).
I don't really know about Vodafone and if carrier specific firmware is necessary in this case. If not, you could use any 815 firmware.
From the site you have linked with the KDZ files..... it seems they are all the same.
If you check the table for H815 KDZs from Vodafone, there are some 10C and 10D versions. Now I compared the fileKey parameter in the URL to the 10C files and the 10D files and also the bytes of the files.
All the 10C version are identical to each other, same for 10D.
Check out this screenshot I made for you: http://i.imgur.com/Ie0w4us.png
Bytes are also identical, so it's pretty safe to say those are the same files.
Dont know why they are listed several times there. The suffix doesnt matter.
I'd grab a 10D if I were you. But I think the Poland 10E should work, too. Better confirm it with somebody else though.
If you flash your system to 10e, you can use the pre-rooted image I used. Otherwise you will have to inject root yourself: http://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586. In this method you create an image of your system and inject root into the image, which you then flash back on your phone.

The correct way to update an AT&T model

So I've just recovered my phone from my 1st attempt at updating to Pie on my unlocked AT&T v35.
But I'm left wondering if the process for updating from Oreo to Pie is somehow different than when I successfully updated from Marshmallow to Oreo.
The process I thought was:
1. Put phone in download mode
2. Connect phone to pc
3. Run the Modified version of LGUP
4. Select your ULM KDZ choice (any of the three will do)
5. Select Upgrade
6. Flash phone
Are any of these steps incorrect and should step 5 be Refurbish instead of Upgrade?

I used upgrade, when going from ULM 8.0 to ULM 9.0. I would assume you would use refurbish if going from stock to another firmware. Of course assumptions aren't really reliable.
I've been trying to figure out if I should do UPGRADE or REFURBISH as well.
I found this: https://forum.xda-developers.com/lg-v30/how-to/guide-how-to-upgrade-downgrade-restore-t3738917
Says REFURBISH wipes user data, UPGRADE does not. If moving from one image say from AT&T, to the Unlocked firmware I'd assume you want REFURBISH.
So since I used refurbish to go to the ulm software from 7 to 8, do I still need to refurbish going to any of the ulm pie variants?

That's what threw me for a loop on my first attempt. Since I'd successfully upgrade from the AT&T 7.0 firmware to I believe the Amazon 8.0 ULM firmware without issues, I thought the process would be the same going to 9.0. But I ran the upgrade through LGUP which was the modified version, and it crashed at 74% and sent me down a wonderful rabbits hole of brickage.

I don't understand how were you on Marshmallow before flashing to Oreo. I'm pretty sure the the V35 launched on Oreo 8.0. But I'm also looking for a way to get from Oreo to Pie on ULM kdz.
I went from AWM12k to ULM10i choosing REFURB and all went well (I followed xatokk's post on the lgV35 subreddit).
When I try to get from ULM10i to ULM20d (Pie .kdz) I guess I only have to drag ULM20d kdz in LGUP window?
I just want to make sure that's not how you bricked your phone before I try REFURB from ULM10i to ULM20d
Any advice would help, I'm a noob at this.
FWIW, partition DL worked fine going first from AT&T firmware to Oreo ULM and then again to Pie. Sadly I had to set up the phone again.

Sorry, Brainfart, I was completely out to lunch on that. I wanted to flash the latest available security update, but since I'm in Canada I could never get that from AT&T so I had to find a way to flash it and that led me to XDA and the whole LGUP process. So you were correct on that, and I did flash the Amazon 8.0 KDZ I believe without issue.
My brick happened when using the Amazon pie KDZ and using the same Upgrade process in LGUP. The update got to 74% and then crashed. I then tried to run the refurbish option but that crashed as well so by that time, my phone was beyond my knowledge of how to fix it

Partition DL was not available in the process list of the modded version of LGUP I used. Which one did you use? I think I found the right one.
Now, selecting PARTITION DL, do I need to select all like mentioned in the Frankenstein Phone thread for the V30?

This phone launched with Oreo and had nothing prior. He's mistaken, confusing some other model.
That's what I did.
The error you experience may be due to a usb cable. a particular usb port on your computer, other software on your computer, and maybe bios settings. The v30 WTF and Frankenphone forums would be good places for background and solutions.
Fingers crossed for a successful flash.

Here's what I did if you don't already found a way. I also faced an error trying to flash to Pie ULM.kdz.
I don't know why but LGUP for developer patched from 9to5lg.com didn't work for me. I tried PARTITION DL it crashed at 91% and I also had to reboot my PC. I kept the phone plugged and reinstalled LGUP.
My V35 was on AWM12k when I got it. I followed xatokk's post on the lgV35 subreddit to get it to to ULM10i choosing REFURB.
I kept the same .dll I extracted from to ULM10i and I did a REFURB to ULM20d .kdz just dragging it to LGUP.
I hope this can help you.
To update my earlier reply on this topic. Somehow flashing REFURBISH from AT&T stock Oreo to ULM(Unlocked) Pie it failed and bricked my phone. As mentioned in another thread regarding unlocking the bootloader and root, I had to call on @motogvasyag to not only unbrick my phone remotely but he also unlocked the bootloader and rooted it. If anyone has any issues with bricking you might want to contact him. He's fast and does amazing work. I only mention this because I am very appreciative of him and his work. I'm not sure why my flashing failed at around 70 something percent but I'm glad to have my phone working again along with the update to pie and root.

@motogvasyag unbricked my AT&T V35 that was stuck in fastboot from a failed flash. Took care of it right away. Phone is now factory LG on Google Fi, Pie, wifi calling and all three carriers. Highly recommended!

Stock LG messaging app

Hi there!
Recently i've crossflashed my V35 from AT&T to NAO USA ULM firmware.
Before flashing the new firmware,my default messaging app was the common stock LG app,but after flash,the default app is Google's messages.
I've downloaded and installed many versions of the stock LG app from apkmirror,but unfortunately non of these are working..when i try to use it as default messaging app,it always crashes and stops.
I tried disabling the Google messages,just in case of conflicting apps,so i can use the other app,but no result.
Ok the Google message app is working flawlessly,but i want to have the old class school app too as an alternative..any idea?
If you're rooted maybe try installing it as a system app? Also grant it the permissions it requires

No i am not rooted..i've granted all permissions it requires but it doesn't work.
Thank you for your reply anyway.
This is not normal and shouldn't happen. Was the stock messaging app missing altogether? What option did you use in LGUP when you cross flashed, whether it was a clean install or you used upgrade option and kept your data? Did you use any batch programs to remove bloatware? No matter what, it still is very strange that a kdz not include LG stock message app. This could also pose a security/malware risk as some out of ordinary behavior by OS could point to it having being altered. Which android version kdz (exact kdz name from lg firmwares download site would be great) is it and where did you download it from? My understanding is that usually kdz file cannot be altered so this is very strange. If you let me know which kdz it was, I can try test it on my spare v35.

Hello and thank you for your reply.
Yes the LG stock messaging app was missing from the begin..when i flashed the kdz and when i completed the whole set up of my device,i started checking if everything was fine.
When i opened the message app,to make my in app settings,i saw it was the Google message app and not the ordinary stock LG app.
For cross flashing i used the Partition DL mode for clean install..i dont know if this caused that problem,but i dont think show,because i've used the same method for my V30 without problem.
I never used any programs to remove bloatware..before cross flash i just disabled some AT&T apps but my device was working perfectly.
The kdz was downloaded from lg-firmwares.com,and the version was the V350ULM20f_00_NAO_US_OP_0218.kdz
It will be very kind of you if you can test it too and give me some feedback.
Thank you in advance!

Sorry, I was mistaken and also, I misread your original post. Since the days of LG V30 I haven't used LG's default Messaging app much as I started using Hangouts to call and text entirely, so I didn't even notice that messaging app had switched sometime in the last year or so. It seems that I have the same 20f version kdz from same website installed on my both V35 and don't have LG's messaging app either. I did look around online and although i didn't find any definite answer, it seems that a while ago probably starting with Android Pie LG messaging app stopped being offered or supported. You probably had Oreo when the phone was on AT&T and it had the LG's default messaging app preinstalled but once you went to Pie ULM kdz it was not bundled with the 20f kdz. By looking at dates on apkmirror website, it does seem that LG last updated it in February 2019. I also installed LG Smartworld and tried getting the messaging app that way but it is not offered there either. The ones offered on apkmirror and elsewhere on web do force close as you mentioned If you do get it working please share details or let's hope someone knows more and have a workaround. Good luck.

Hi!
Before crossflash i was on Pie with security patch level July 2019..this is how i received the phone from the seller..maybe this is the way the ULM kdz is been released without the LG stock messaging.
I dont know if a pre-20f ULM version has it included.
Maybe somebody else can give us this info.
Thank you anyway for your help.

Please help. Upgrade/Flash to ATT Moto Z2 Force, and restore google backup

I just bought the Moto Z2 Force today (ATT version yuck). Basically I need to be able to restore data from google's automatic backup since I have apps and data there that cannot be reproduced (my launcher was discontinued etc). Since the ATT version cannot upgrade past android 7.1.1 it cannot restore from my old phone which was at a newer version of android.
Is there a way to kill two birds with one stone here? I don't want ATT on my phone but my main priority is to restore from google backup. What ROMs allow google restore? Is there a stock unlocked (not carrier version) of android for the Z2 Force that I can flash? This would be optimal for me since I like the android experience.
Would Lineage or Resurrections Remix work? (I have never used those so Idk how close to android they are. As long as I can backup I'd be happy to try).
Any help is appreciated, thank you!
further questions...
I see this post:
https://forum.xda-developers.com/z2-force/development/att-ocxs27-1094717-xml-zip-grabbed-t3905967
which sounds like it forces an update on the att phone. If I follow these steps I'll be able to at least restore from my old phone? But then is there a way to unlock / remove att bloatware after that?
EDIT: update. I'm using the LMSA to flash a newer version as found in this thread:
https://forum.xda-developers.com/general/general/update-moto-lenovo-moto-smart-assistant-t3951714
hopefully this will let me restore. But I still need to unlock the phone and remove bloatware.
