Well If you would have a backup of efs yes... Which you can't have until you have twrp or similar installed.. So idk no way to recover it without a backup. Is the phone still booting? What is working what not? Do you really mean the imei or "imei sv"?
You wrote you send LG the imei? You have not go through the official unlock page by LG? The imei was taken from the sticker behind the battery? Or from within a booted rom?

easy contact LG and tell them what happened. since you had a working imei and after unlock it was deleted, wiped

I'm having same thing, although it happens when I try to install a custom rom. Imei gets wiped. Even though i have a backup of the original efs in twrp, restoring it makes no difference.
Sometimes when i try to restore the original non rooted system including backed up efs i still have a problem with no mobile signal and blank imei. Restoring efs from a different backup fixes it for some reason. Apart from using non rooted non custom Rom i basically can't get mobile signal.
Any ideas?

It is for unlocking ur phn to use any network operator i.e any sim card.some devices like M-150 mostly comes with network boundations.so we need to unlock it to use any desirable sim card

If you are trying to unlock it, I believe firmware M15020e or M15020d can be unlocked for like 2.00 (via ebay)
the newer firmwares L, M etc.. cannot.
Your firmware will be listed on the box or in settings/about phone info
If you have the newer firmware, you could possibly "downgrade" to the m15020 d or e version.

By now downgrade is the best solution to unlock this device with M15020L/M/N firmware. If someone with the older firmware (E,D) that actually can be unlocked, pls submit it so we can downgrade, even when we'll still need a method to do so, cause there's no LGUP DLL for this model yet.

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.

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

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.

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.

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.

You could try a factory restore if you haven't already. Also, the LG Bridge app for your pc (download from LG site), may provide an update or an option to reinstall your firmware.
The alternative is to check (private message) with other H810 XDA owners in relevant threads to see if someone has a copy of a suitable stock firmware.
Note: If you want to install a custom rom to update to the latest security patches, etc., , you can unlock your bootloader unofficially with steadfasterX's brilliant work (many H810 users have gone this route now) - check it out here: [UNLOCK][UNOFFICIAL][G4] Unlock **ANY** LG G4 device with UsU. Read the OP thoroughly and make sure you understand it fully. You will have to have an ARB version of two or less in order to go this route, so before upgrading to any other H810 firmware, check your ARB version with SALT.

I already tried the factory reset, but no lights on.
Tha LG Bridge won't work as i know cuz i don't have active AT&T Sim card and i don't live in tha usa.
Asking other H810 XDA Owners for a suitable stock firmware, i really didn't think about it so i will give it a try.
My H810 already have H81021y software which has ARB 3. so no root for me, i guess :crying:

Yes, no root, no bootloader unlock for you, unfortunately.
However, ALL MAY NOT BE LOST ... check out this thread that I found: link... to Android 6.0 MM h81021y archive tot
There are a couple of links to the firmware you seem to be looking for. It is a TOT file but you should be able to flash it following the TOT method as outlined in this thread: [Guide] LG G4 Stock Firmware (Go Back to Stock) KDZ & TOT Method - scroll down to the TOT method.
Good luck.

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.
US991_UsU_unlock.zip in develop mode worked great.
twrp-3.5.2_9-PREVIEW-275_g4.img worked great.
however, i have a new issue. when i flashed US991_UsU_baseband_flash-in-twrp.zip my SIM is no longer recognized; mobile data can't be enabled, says connection not allowed so can't add an APN. LGMENU shows normal APNs (ATTPHONE, NEXTGENPHONE, etc are gone). has a couple prepay APNs listed that i don't recognize and can't edit thru LGMENU. SALT GPT is H811 which i thought was just for the ROMs. do i need to actually flash H811 basebands? or just flash one of your H811 ROMs like lineage 18.1? not sure how to fix this. again, any help/guidance is much appreciated.

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
