Hi!
I have this G7 with the model LM-G710V with an unlocked bootloader and managed to successfully flash Phh-Treble by following this thread:
https://forum.xda-developers.com/lg-g7-thinq/development/rom-phh-aosp-8-1-t3808649 :victory:
but then i would like to convert back to stock but unfortunately there are no available KDZ for G710V in the interweb.
would it be possible to convert G710V to G710EM ,or to a similar effect, by flashing 10b Vendor img and boot img then the kdz found in this thread:
https://forum.xda-developers.com/lg-g7-thinq/development/dump-g7-stock-vendor-t3840834 ?
or would this just leave me with a dead bricked phone?
additional notes:
bought this phone as a secondhand from someone in facebook with the bootloader unlocked and with, as the seller stated, "G7+" rom with issues.
no backup was made before
Thank you for anyone willing to answer! :good::fingers-crossed:

Hello @xElouise, according to the LG Open Source Code Distribution website (here), the G710V is equivalent to:
G710VM
G710AWM
G710AWMH
G710VMP
G710VMX
KDZs from any of the models above should work fine, just note that they may come with carrier bloatware. Reflashing the stock firmware is the same as any other G7 version (here, up to the first half step 5).
Does your phone have an IMEI code and working telephony? Because from the info I have gathered on the internet, looks like the G710V is a retail demo unit without either baseband or IMEI.
Hey there! Thanks for the reply!
Unfortunately since after flashing Phh-Treble LGUP does not recognize the phone anymore (Shows up as Unknown)(maybe because i flashed the vendor img(?) idk.)
Anyway, since back then before flashing Phh-Treble i was already trying to flash KDZs Thru LGUP, but unfortunately LGUP throws me error saying it does not support cross flashing.
I have tested the following before:
G710VM - LGUP Error cant cross flash G710V to G710VM
G710AWM - LGUP Error cant cross flash G710V to G710
G710VMX - LGUP Error cant cross flash G710V to G710
This unit IMEI & Baseband says unknown. This also has the white sticker at the back with some of it's details like unit model, FCC Id, etc.

Try hooking it up to LG bridge. It will automatically recognize the phone in download mode and it will update it to the latest stock.

LG Bridge fails to recognize the phone on download mode.
It says " Notice: Can not connect. disconnect the USB cable from your computer and reconnect" done this multiple times, even swapped usb cables with other phone
edit: So i was able to make LGUP recognize the device again but still same problem with cross flashing <see pic for reference>

You can contact the guy that sold the phone to you and see if he has a dump. Otherwise I can pack the system and the vendor but I'm not 100% sure if it will work
Hi, is your unit the demo unit one, without phone function and with retail mode app? Did you encounter any issues with the flashed ROM so you're changing again? I managed to land one of those demo units but there's too much restriction for usage so I was thinking of flashing another ROM but I'm a complete noob with regards to that.
Thanks.

@LameMonster82 , The seller said that he bought it off someone when it has boot loop issues and have his buddy fix it for him & he does not have any backup (guess that makes me a third hand(?) not really affected by it since i got the unit for a dirt cheap price around <$100 and it's quite a smooth unit too).
If you could, in your spare time of course, make the pack that would be really much appreciated! Thank you very much!
@ceezae , This may be a demo unit since i got it without any sim functions and a blank IMEI. I don't know about retail mode, though there was an widget applet before which showcases LG G7's features. I already bought the unit with it's boot loader already unlocked so I have no idea how a G710V got unlocked. When i bought the unit it does not have any audio at all either thru the headphone or speaker that's why i flashed a custom rom.
Anyway , since I flashed Phh-Treble 8.1 the phone's working smoothly aside from the aforementioned bugs in this thread
I am going back to stock since i can not utilize the quad DAC feature in custom rom and I could not get Gcam to work (it either crash or extremely Laggy)
I would also like to mention that:
I can not seem to boot to recovery via (Vol down + Power button) it always say that "Factory Reset is Disabled by Kill Switch" even though OEM Unlock is ticked in the developer settings as well as unsynced Google Account.
And my internal storage is showing that I only have 16 GB of internal (would be easy to fix with TWRP but again no luck with custom recovery)

Hi there!
I am terribly sorry but my device is kinda a bit soft bricked(?) at the moment.
I was trying to flash the Stock Korean PIE KDZ and was successful but it had problems like WIFI can not be turned on and Random Reboots.
I think I also have lost access to Fastboot since the phone only Reboots itself normally.
My dumb self did not make a backup so I am a bit screwed at the moment.
Someone with an intact phone (which hasn't been flashed) will have to pack up their partitions and post it here. The G710V seems to be technically similar to the G710N but can't actually be flashed to a G710N (you can force this through using LGUP but it results in a phone that crashes all the time due to some issue with the wifi driver).

Hey, I tried backing up these via adb shell myself on my G10V but... "permission denied". Great. Probably because the demo units force a Retail Mode device administrator that you can't remove at all. Can't even access the page itself in Settings ("you are not authorized..." blah blah). It's a shame, because I was really looking forward to helping OP.
have you succeeded I have the same problem as you

Hi,
I just got a refurbished LG G4, and i'm unable to reboot to fastboot mode. I want to install TWRP and LineageOS. Before that i have to unlock the bootloader.
I followed this guide : [HOWTO][H815] Complete Guide to Unlock Bootloader + TWRP + Root + Xposed + ViperFX . I'm stuck at "1. Unlocking the bootloader officially" -> viii) ...adb reboot bootloader etc...
I tried on Windows and GNU/Linux "adb reboot bootloader" and "adb reboot-bootloader", with and without administrator/super-user right without any success....
The phone reboot to Android. However the phone can reboot in recovery and download mode.
The phone is still in android 5.1, and come from T Mobile (the phone suggest upgrade from T Mobile).
One strange thing is the dmesg usb connection log on GNU/Linux :
Code:
[195563.124097] usb 2-2: new high-speed USB device number 43 using ehci-pci
[195563.257487] usb 2-2: New USB device found, idVendor=1004, idProduct=631d
[195563.257498] usb 2-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[195563.257506] usb 2-2: Product: LGE Android Phone
[195563.257512] usb 2-2: Manufacturer: LG Electronics Inc.
[195563.257518] usb 2-2: SerialNumber: LGH81029e8b9d6
The serial number start with H810, and the phone is labelled H815 in the stickers under the battery, and on the info on Android...
What can I try to get the fastboot mode?
The refurbished phone says "H810" on download mode. The IMEI was modified too to appear be a H815, as the stickers etc... The phone is counterfeit...
Someone have/had the same problem?
Settings -> developer options -> OEM unlock enabled?

frankenphone maybe someparts from h810 and some from h815 and manipulated or edited software.. we had this in G2 alot. only wasy to find out was by looking at motherboard its printed what variant it is only looking at it physically. mean to take out on you hand and read the number model.

I requested a refund. The vendor falsified the IMEI and model number. The Android image seems to be frankenstein-like too. It proposes me to upgrade with "T-Mobile" (and fail at reboot), and the default welcome page on the web browser is att.net (after a complete wipe out)...
I don't know how to solve this problem. I need more LTE band (working but it's poor comparing to my Xperia Z1c). I have the band 7, but I need band 3, 20 and 28.
1. Which method (unlock bootloader, install TWRP, etc...) i must use the one for H815 or the one for the H810 ? Which image of Lineage OS ? Logically the H810 one?
2. Is there a way to revert back the phone to its original model and IMEI ?
3. Finding the original IMEI? Maybe with the original SN?

I tried LG Bridge, and it detect the phone has a H815. When it tries to upgrade the phone, on the reboot, on download mode, the phone show information like H810 H81010o, and stay stuck here. The software on windows report a fail.
"LG Phone From" report a H815, with the IMEI on the label.
I read that it's possible to modify the model name(here on XDA) and the IMEI (QPSK or LG "something" by Octopuss). Seem's that some vendor in Aliexpress are not very straight...

Did it. The discussion is on the way.
Opened the phone, the mainboard is labeled VS986.
So :
-Download mode claim H81010o
-Android show H815
-Mainboard is labeled VS986
So my phone is a VS986 (ie the mainboard). Is there a way to make it a VS986 for Android and Download Mode, like the mainboard was originally?

I tried the KDZ for Verizon (VS986). LGUP fail because the model reported is H815. I will try with "LG Flash Tool 2014".
Another solution could be writing directly the eMMC with eMMC DL Tool. I didn't find the VS986 bin file for now.
I successfully flashed the phone with "LG Flash Tool 2014".. It's now a VS986 (claimed by android) and as labeled on the motherboard.

is all working .. too bad you wont have unlocked bootloader.
Yes, and :
LTE isn't working (verizon limitation)
Sticker labelled H815
What I've found out about my G4 Frankenphone so far:
- sealed box said LG G4 'dual LTE'
- sticker on phone under battery says H811 and has a valid corresponding IMEI
- phone model in settings/device info is H810 with IMEI 0! :crying:
- download mode screen is in Korean with some mention of F500L v11d...
- the phone came rooted running LP
- it is registered on my network, working 4G LTE!
I've been hoping to custom OS and reinstate a sensible IMEI but from everything I've read and not been able to do (can't flash anything and always coming across 'barriers') and to avoid bricking the phone, I am giving up. I have contacted the vendor and told him to find a replacement, clean G4 or clean G3. Seems to me that the G3 is a lot more versatile in terms of the support, especially here, for it. I shall miss the spec. of my G4 and it's greeeat camera!
- unless someone can convince me otherwise or point me to a G4 FrankenRom link and successful instructions!

open phone . take out mother board .. and read plaque model. if sprint flash sprint KDZ and LGUP. if H815 then do that .. thats the only way to be sure.
U have a refurbished model.Go to nearest mobile repair shop & take out your motherboard to see what model no is written on this.Then flash a rom accoringly. Don't flash any other rom just by assuming else you will brick your device.
Yes my phone is refurbished...
But how to flash the rom?
If I found it to be a sprint version and flash a sprint rom ...it will be locked?I am using phone in India...
Any chance to root the phone and install twrp?
Then flash a custom rom?
Please help...

Most probably it will be locked cause most higher Android versions LG has blocked rooting or unlocking..But you can always browse few threads.
Mine is also a refurbished model with F500L motherboard,LS911 body & had H815 global rom installed out of the box.I am currently on F500L Nougat locked & unrooted..I have tried almost every method.It failed to root & even to enter fast boot.
If you get your proper model no on motherboard then just flash the rom with ToT flasher in download mode with respective DLL.

Your network is locked?
You cant unlock it?
Can we degrade our Os to lollipop to get root?
Even I cant turn on the Enable OEM unlock under the developer mode...
Any more advices?
Please help.....
I have tried almost all h815 ans ls991 roms with all flashing methods but still unable to successfully flash my device...lg tot flash tool always show dl error after 4 to 6 percent of flashing...
Please help
Any idea's?
Pick the phone, and send it to the place where you bought it. If you have warranty the repair is free, if not, then you must pay sadly.
Still no solution, I even cannot enable OEM unlock under developer options...
It automatically disables it...
Please help
Just experienced this issue after changing sim card... Call and Camera stopped working over and over again.
How I solved it: Go to the specific app that is causing you trouble, and clear cache/files (too bad I only found this after 3 factory resets).
Maybe it will help ... LG G4 CAM
Helle everyone, I recently purchased an LG G4 H815 running MM from eBay, it is supposed to be INTERNATIONAL VERSION, but I had noticed first that Android PAY does not work (when I try to launch the app it does not let me in and says that I am running a custom ROM or I have a rooted phone or unlocked bootloader) which none I personally did. Then I tried to verify my anti-rollback version because I couldn't update to Nougat, the HIDDEN MENU code supposed to work for my model H815 didn't work, but instead, the code related to the American versions (ATT and T-Mo) WORKED, AND MY DEVICE HAS anti-rollback version = 4 !!!! as far as I know, the most recent one is 3, how is that even possible??? (see Pictures for more infos)

There are many Frankenstein devices out there.. One thing is 100%: you have a refurbished device. So it's definitively NOT a pure h815.
H815 devices have no ARB!
Please make a backup of your device with SALT ( https://bit.do/SALTatXDA ) - basic is fine. And share the resulting files i.e. via Google drive.
Having that backup is crucial important regardless. And I want to take a look into your bootloader stack to find out which one is installed.

H815 devices have no ARB!
Please make a backup of your device with SALT ( ) - basic is fine. And share the resulting files i.e. via Google drive.
Having that backup is crucial important regardless. And I want to take a look into your bootloader stack to find out which one is installed.

Thanks for the reply man, i really appreciate it.
1/ Yes it is a refurbished device
2/ I think it is Sprint version LS991 (according to the ABR - Sprint is the only version that has version 4)
3/ I checked the IMEI online and it confirms that it is a SPRINT device
3/ I found online that there is some CUSTOM ROMs that "converts" literally any version to H815 (mine shows 4g LTE logo when I am using ONLY 3G WCDMA in settings)
How to retreive the bootloader stack info in order to share it here for you to take a look ?
I am now trying to install SALT in LINUX - I will keep you up-to-date

Making a backup with SALT will also get the bootloader stack. Just share the files afterwards.

Pls paste the SALT debug log in advanced menu as well. It's enough directly when started SALT with the device connected.
Many thx
Nvm got it. The important stuff is in your screenshot.
You have a converted device. Meaning you have the ls991 bootloader stack plus the h815 system. This is possible but more interesting would be: is your SIM working? Do you get mobile Internet? 3g,4g?

Many thanks for reply, yes everything works fine (Android Pay does not work), DATA works fine BUT even using ONLY GSM/3G WCDMA (no LTE) in the settings, I always see the 4g LTE logo when using DATA, I think they somehow changed/ replaced the 3g data logo in the status bar with 4g LTE logo, in order to make the user believe the device is compatible with his LTE carrier frequency (which is not correct of course)
This SPRINT device does not support LTE in the country I am using it in (Czech Republic), I verified it with the help of willlmyphonework.com website.
This is really so disgusting and unfaithful behaviour from SOME Chinese sellers on eBay, the SPRINT version is the cheapest one, so in order to RIP off customers, they CONVERT these models to H815 in order to sell them for more, and not everyone would have the knowledge to dig deep into the device info in order to verify the legitimacy of their product specs, this is sad...
Anyway, what should I do now which this devise? how can I at least install Nougat or have the OFFICIAL firmware without breaking the device??
Thanks for your time and precious information

Well.. We don't know if it is a ls991 or a h815 or a complete other device. The only way to say this for sure is to open the device and looking on the mainboard(!). But regardless you have a fusing device now and so you cannot install a h815 bootloader stack anymore. Say thx to ARB ( https://bit.do/antirollg4 ) which can hard brick your device.
It SEEMS that you can boot h815 ROMs but if you try to replace the bootloader stack coming with the N zip or the TOT (which you can find here on XDA) it will hard brick.
Interesting is that h815 is able to boot. It MAY be possible to boot N by just replacing modem, system and boot partition though. That depends on your bootloader stack.
Try to boot into fastboot from android:
adb reboot bootloader
You should see the fastboot screen. Could you make a photo of that? We MAY have luck and its a special one.

Unfortunately this command adb reboot bootloader just reboots the phone normally to android ( normal reboot)
I couldnt boot into fastboot because the Send command returns FAIL when I type id (so i cant move on in the process ...) Maybe locked bootloader??

Too bad. Try that :
Power off phone
Press vol down and keep it pressed
While doing so plugin the USB cable and wait
You may see fastboot now.

Well no. Some firmwares do not allow to boot into fastboot that's not that unlikely.
So what I can say is that you have a ls991 bootloader stack with a h815 system so it MAY be possible to install nougat but not yet. I will integrate flashing partitions to SALT soon. Until then you have to wait.

read the SALT thread. I provide changelogs for every release.
flashing is possible even now in a beta state. waiting on IRC (read the SALT thread - OP) is the only way if you want to participate on the beta test.

Hello! I have similar situation I have H815 ... but LGUP says H81521y it seems it has some strange software/modem/rom uploaded. It is marshmallow 6.0 I cannot get into fastboot mode so I cannot unlock bootloader. I tried to install TOT of Nougat via LGUP but no luck cause it turned out I have antirollback V3.
Is it possible for me to install TWRP and then any custom ROM? I don't know what to do right now...

It seems it's H815 with AT&T Software with anti rollback v3. Adb reboot bootloader just restarts the phone, I tried to enter bootloader by keys combination. It enters firmware update mode.
I think due to v3 rollback I cannot do anything with this phone, am I right?

Correct (axcording to my experience). I had the same issue with my previous phone. It turned out to be a ls991 with H815 software.
The only way to know your Hardware is to take a look inside the phone , you will find it printed on the motherboard.

Mine has H815 printed on antenna and few other parts, in system it also says H815 in LGUP its H81521Y I think it's H815 with AT&T bootloader and therefore they flashed anti rollback V3 so at this point I cannot do anything...
As you have read in the FAQ sometimes when you send your phone away to be repaired (under warranty in my case) you may get your phone back where what is flashed on it does not match the actual hardware. In my case the motherboard was an H810 and the software claimed it was an H812, even SALT thought it was an H812.
Well the good news is just flash on what your motherboard says it is. In my case the H810 unlock and roms both work great. Everything except for the flashlight works but that is a known problem with the LineageOS 15.1 rom as of writing this. The phone has been in use for over a week with no freakouts, reboots, excessive battery drain, overheating or otherwise.
REMEMBER! caveat emptor, this worked for me and might not for you!
TL;DR you should disassemble your phone and make sure the hardware matches up to what you are using to root it with. And also make damn sure you carrier unlock it first before flashing on a custom rom. The custom roms will not carrier unlock your phone and in my case claim to be successful and fail silently.
One additional thing to note here, I do not know if this was incorrectly flashed by the tech or if putting on the H812 rom was intentional. I did not use the stock phone whatsoever so I do not know if all the hardware (calls/camera/flashlight/etc) even worked properly.
@steadfasterX per request.
Hi, I too have a frankenstein h810 device, but I only realized it after I unlocked flashed a custom rom and everything. I bricked the phone, but I'm using the sd card unbrick method to run the phone. With that said, you mentioned to use h810 files and everything should work fine. I've tried that, but with little success. Either there would be no sound or LTE or no video. I'm currently running h812 roms/modems and my lte does not work and my battery performance is less than stellar.
My question is, what are the current builds of the files are you using? Also, what can I do to unlock my phone? I got the code, but it does not work and you mentioned that its best to unlock the phone before installing custom roms.
One last tidbit, when I go into download mode and try to use LGUP to unbrick the phone, it says my device model is unknown. Is this something to do with the frankenstein motherboard?
Thank you

LGUP cannot recognize my phone model while it is in download mode. Even salt is all over the place with its information. I bricked the phone a while back so I forgot exactly how I did it in the first place.

Ok, I managed to get LGUP running with an edit to the build.prop of the device. LGUP says the phone version is H81220x. I checked the motherboard and it is the same model as baconbacon's LGG4, h810. What are my choices on flashing a proper KDZ? I've read certain things about ARB, but I'm not 100% sure how it works. Looking at the LGUP tool, it wants to select a .tot file. Any suggestions?

You should be able to.flash 812 software on it then. Google 20v kdz for 812 and flash it with lg up. If .kdz extension isn't available select refurbish....it can be tricky but eventually it will give you option to flash kdz

I want to root an LG g4, the bootloader and/or recovery seem to be missing from the device. Purchased used off ebay. Is the LG LS991 [H811] Model (Sprint) (also seller claimed its unlocked and that seems to be so when i tested my sim). I can only get the phone into download mode, so when i check it with SALT I see the antirollback says "40". I heard the term frankenstine device thrown around before. IS it even possible to root this phone anymore? IS it possible to get access to the bootloader? I feel like i've been walking around in the dark for a while. I would greatly appreciate any advice

Hi, I've got a similar issue. US991 bought new 2017 from LG via newegg. Advertised unlocked, assumed that just meant carrier unlocked, which it is, but also has OEM unlock flag in developer options. LGMENU shows ARB=2 but SALT stable shows ARB=20 so won't flash USU. SALT develop mode shows ARB=2.
Do I USU from develop mode? Does this one need USU (have never tried to flash TWRP or root or anything. Any help/guidance is welcome. the MM LG pushed to it in 2017 doesn't have firmware support for VOLTE which i was hoping to get by flashing a new ROM since i have have no calling since the AT&T 3G shutdowm.

only H811 does NOT need UsU. The h815 can be unlocked as well but only when you have the unlock bin already as the LG website closed. so: yes you need UsU.
yes keep SALT on develop and flash UsU there. The good thing is that FAQ #1 applies to your device so you could even go back if something is not working as you want it.
Thanks for your help steadfasterX.

well there are 2 problems here:
1. not many us991 users here so less user feedback
2. usually no one wants to stay stock so less user feedback
the main problem is that the baseband files are incompatible with your bootloader stack (hopefully its just that). a fix for that would be creating a new baseband flash file from your modem partition. pls provide it from your backup BEFORE using UsU and I can take a look
