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)
( Unfortunately I couldn't figure out a way to upload pictures here so here is a link to Imgur)

Thanks for any further help or 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.

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...
So I was on Oreo and accidentally flashed back to 7.1.
Didn't brick it but now it doesn't recognize my sim even after flashing back to Oreo.
I tried to fastboot the tmo baseband but no luck there.
Anyone run across this or have any suggestions?
That was one of the 1st thing I ran across in the Oreo update thread. With development just really getting fired up I'll be surprised if you find a fix. If. I was you I would flash the mod that hides the unlocked bootloader warning and take it to TMobile. It's only a 5 dollor charge for defective devices. I've returned a total brick before.
So I am on the same board. The problem is I'm in UK and I cant claim warranty repair. Also my warranty was void in December soon when I generated bootloader unlock key.
SO what have I tried so far?
Hard brick bootloader to state when it is Qualcomm loader- only blank flash and Oreo Flash All is able to bring it back to live.
Ive also tried boot from B slot in twrp but it looks like my B partition is messed up. Fastboot will show red warning about no flashable A/B slot and only oreo flash can get it back to boot because it will oem lock itself.
When I get back fully on unlocked bootloader to 7.1.1 I cant update via adb sideload or update menu in settings. Both will fail.
Sim looks like it is detected on start but when taken out and slided back in it wont show up.
I have QCN area backed up with nv data but it wont help me.
Please note when boot is bricked oreo flash all will flash it on locked bootloader and will not show warning screen at all about botloader. However I was unable to boot to recovery from that point so I had to unlock it and flash 7.1.1 then oreo again.
So if someone could do nandroid backup of clear not set up rom it would be great. I can try restore it. I dont even know if twrp is able to do backup on A/B device.
Also if someone could read NV data from phone and share it ( from phone with working radio of course) would be really appreciated.
Can someone PM me NV backup? I need urgently qcn file. I think my hw partition is messed up. Please don't share it in this post as it can contain IMEI.
this is what i did, and why there is a giant post in caps in the thread that says not to do this. You essentially end up with a bootloader mismatch which hoses the radio. the only solution is a replacement.
and DONT DOWNGRADE !!!

Sorry but warning isn't clear. I did not enjoy Oreo and was looking for unlock method.
Also bootloader match to my current Oreo rom and radio but still no sim detected so I think it is hw partition messed up. When I flash retail Oreo on it bootloader just change itself to retail Oreo version. Still no sim.
Device is useable as paperweight with WiFi
I think I've found a way to unbrick your phones guys!
If someone still has their bricked phone could they tell me what state they're in? I managed to successfully unbrick mines but had to stay on 8.0
Everything about the phone works 100% except the Sim slot. It's like it can't read the Sim. It knows there is a sim in, but it can't access it.
On Oreo oem retail version.

I'm happy to stay on 8 but need my sim get back to life. All works fine except SIM card is not detected.
My phone boot as normal. When downgraded it won't accept ota's. It won't install it via sideload too. SIM card remain undetected no matter what rom and what version( T-Mobile, retail, etc) when I try to boot from slot B via twrp it won't boot. It will show bootloader screen with unbootable a/B partition.

Not OP, or guy with a link, but I did a similar bad thing and ended up on the retail Oreo without working SIM. What I did was take the modem file (the one that you fastboot flash to modem) from the tmo oreo zip and replaced the modem file in the retail oreo zip with the tmo one -- just change the name of the tmo modem file to the one that comes in the retail oreo zip and then run the retail flashall.
Still no way to get the latest tmo update that fixes some volte issues, though. Since I purchased within 14 days, I just added insurance and will probably end up drowning the phone to replace it... unless someone has a better idea. :/

guys i tried blank flash oreo on mine bricked tmobile moto z2 force and it isnt working, any help would be great on this , thanks.. and also i have tried many blank flashes some for even other moto phone models none worked so far.. one or two of them got really close the oreo one did but failed at last part... tried about hundred times and yes i even tried holding down power and volume button with no success it didnt work it did though recognize the phone but still failed trying to boot or flash it though... seems to me it needs either up to date or just different blank flash it seems, but i dont know that for sure...

G'day everyone!
Much like @mr turtle droid , I've decided to create this sister thread to keep us all informed of the progress towards Root, TWRP, and ROM's for the CARRIER UNLOCKED LG V30+ variant.
At this point in time (15:50, 21st Feb 2018), LG HAVEN'T placed this model on their Unlock list, on the LG Dev website. The LG Models that ARE there are the H930 and the H930G for the Euro market. I've emailed LG Australia about this, and am still waiting on a response, but doubtful I'll get a helpful one. I've also asked on the LGDeveloper twitter page, and received a stock standard response: "We are sorry that we can't be of much help. If there are any changes to the supported devices, we will let you know via our website".
Not being a dev myself, I don't know if any fastboot commands work or not, so if someone can get us going with potential methods, that'd be sweet.
I have a link for the Firmware *.kdz downloads, for what it's worth. Link is found HERE.
If anyone has any ideas, please share them. The more that we know, the closer we get to unleashing the full potential of this great phone.
Also, if someone could explain why exactly LG doesn't unlock all the different models of their flagship, or at least give an ETA for the unbranded one's, that'd be sweet. Is it because of licences, or patents or something? Or is because it's a Dual SIM model? Curious more than anything.
It just seems nuts to me that the V30+ that I bought from JB Hi-Fi wouldn't be on the unlock list, if it's an unbranded / noncarrier variant.
Once again, this is for the carrier UNLOCKED variant, H930DS.
If the bootloader is unlocked on the H930DS then this thread might be a step in the right direction for route

Hi, reports on there suggest that only one sim is working after using that method.
Seems like flashing back some partitions from another ds model with lgup could be the solution.
I have been tempted to buy this phone only put off by no root.

Is second sim not working at all, or is it possible to use it as a data connection only?
Hi, I have only had mine for 3 days so haven't tried yet
I think as a H930 single sim unlocked bootloader is loaded, you will only see 1 sim.
Dont quote me on that as I am still reading up
Any experts who can answer?
Both SIMs work for H930DS. Just flash unlock bin and TWRP as described in WTF thread. Need to mention that I've had official H930DS Oreo update prior to attempting this.
Hi, well thats the first time I have seen that stated.
There are no specific instructions for the DS.
Are the one's with only 1 sim just flashing a single sim rom and keeping it for the bands or something?
I have V10e-AME-XX and no Oreo update is showing.
So do I
LGUP to convert to open single sim H930
Adb reboot bootloader
fastboot flash unlock new_unlock.bin
Install Twrp
Then how to get dual sim rom?

I wouldn't flash single sim rom on a dual sim device if I was you. You need to flash Oreo dual sim firmware and then everything is straight forward. Bootloader unlock process as well as flashing TWRP won't effect any fuctionalty and procedure is simple.

But you had to flash H930 to get bootloader unlock. You seem to be contradicting yourself... please clarify?

Hi, still not quite getting it
Is H930 eu 20d a dual sim rom then?
Otherwise what exactly is "Oreo dual sim firmware"

Yes, that's what I am trying to clarify.
Just a bit paranoid about accidently flashing a singles sim rom as I have had this worry on my M8
OK, hang on, just searching around, is it this?

I have a H930DS flashed with H930 firmware. It's rooted with Magisk installed. Both SIM slots are working. Both data and calls are fine.
I used the H93020d_00_OPEN_EU_OP_0326.kdz firmware.
The phone is still identified as a H930DS and the software version is called V20d-GLOBAL-COM

Thank you. So you flashed the H930 Oreo KDZ. Just like the instructions say in the WTF thread.
To me, the only way for H939DS users to do this is to flash H9390 and run the command. One India H930DS user says that is what he has done and he has BOTH SIMS. Now you have confirmed it. That's two H930DS users who have bootloader unlocked and rooted, just like I said they could do -- and they both retained dual SIM functionality. Every V30/V30+ can be bootloader unlocked and rooted, except for the T-mobile H932.
Even @crubbish seems to infer that but he contradicted himself -- saying he didn't flash the H930 firmware, which I'm pretty sure HE HAD to -- which is frustrating.
hmm, so I have just re-run LGUPP and device is recognized this time but I get and error 0x8... Please us latest dll LAF protocol version is not match
Do I need to go back down to nougat and them back up again?

No, the H930 variants (which include the HD30DS) do NOT need to downgrade to Nougat.
You just need to figure out how to install and use the LGUP.

@crubbish, I'm sorry but you seem to be contradicting yourself. Please clarify. You either used the WTF instructions or you didn't.
I WROTE the instructions for the WTF thread and they clearly say all H930 variants -- which included the H930DS -- needs to flash the H930 Oreo KDZ to get the fastboot flash commands. So, unless you are saying you somehow managed to enable those commands some other way (and H932 T-mobile users would be all ears for that!), then you did indeed flash the H930 Oreo KDZ, did you not?
Two other H930DS users -- at least one from India -- have used the WTF method, of course flashing the HD30 Oreo KDZ -- and they are bootloader unlocked, have TWRP custom recovery, rooted, and have dual SIM functionality.
Unless you have figured out some other way, THAT is also exactly what you did.

If you've connected the phone to a USB3 port, try a USB2 port instead. That usually works.
Also, if you're not using the cable that came with the phone, try that as well.

No, you need a newer DLL for LGUP which can be found in this thread: https://forum.xda-developers.com/lg-v30/development/lgup-oreo-dll-file-v30-t3779441
Put it in the C:\Program Files (x86)\LG Electronics\LGUP\model\common (create the "common" folder if it's not present). Start LGUP WITHOUT Uppercut.

Thank you.
Besides trying a different USB port or different cable, also try to enter download mode manually (power off completely, then hold volume up button while plugging in USB cable), THEN open LGUP to make it recognize your phone.
Also, try a different computer if none of those suggestions work.

I've had Oreo OTA flashed on my H930DS after which I've followed WTF procedure without flashing any other firmware. Sorry if I wasn't clear on this.
It looks to me that as long as you're on official Oreo firmware you can appy unlock.bin straight away, no need to pre-flash any other firmware. Also someone has reported on losing dual sim functionality after flashing plain H930 firmware, that's why I think it's safer to flash specific dual sim rom for dual sim devices.
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

Is that where you got the files? Then I can just extract them from a stock KDZ from the internet myself. I'm wondering if there is anything I can do to unbrick my phone. 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
My phone is a 810 with 811 software. So when I used lg up I flashed it back to 811

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.

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

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).

I have a dump. I did it using the EFM program from the Z3X team.
If you want to try to restore, write to the telegram.
