Hi,
I am confused regarding my LG G4 model number.
Because Under About Phone -> Hardware Info it shows LG-H815.
But when I connect it to pc & using adb devices, adb lists it as LGLS991e484402e.
Also LS991 0423 is printed on back of the phone near camera & speaker.
But under the battery the sticker with IMEI displays LG-H815 !
What is the model number ?
I need to find it in order to update it.
Are you checking for compatibility with a rom? If so, H815 is the number you're looking for.

& Is it possible to run H811510h on LS991 model ? or is it possible to change LS991 model number with H815 ?

Don't worry about the LS991 number. H815 is the version of your phone, the G4 international.

How are you planning on updating? Flashing a rom from xda-developers? If you're not sure, I'd recommend something like imperium rom, which is based on stock and has much the same behavior but is rooted with more options. Just make sure to download the one for H815. Of course, you'll need to have an unlocked bootloader and custom recovery before you can do this. Do you have custom recovery already?

Is there any way to install custom recovery without Download mode (& of course without root !) ? Because there is one more problem ! I cant get into download mode. If I use Vol up+ & insert usb cable then I get "Secure boot error 1014" & if i use adb reboot-bootloader or reboot bootloader phone restarts normally. Also fastboot mode is not working. Fastboot devices either do nothing or waiting for device ! USB debugging & OEM unlock is on.

The only method we have for our phones at this point is to use Download mode.... have you done some research on that error? Google or the forum search tool?

Yes I have searched for that & some related errors. But almost all of them says that it is because of locked bootloader & to unlock the bootloader I need to enter fastboot mode (Not working as of now) also I have tried many drivers mentioned in the posts (LG universal, LG WHQL etc), LG Bridge, LG PC suit, LG flash tool, LG mobile support tool etc & Also tried the same things on Windows 7.
I don't really know much about fastboot problems, you'll have to look elsewhere for help. Sounds like that's your next step, though. Look for people who can help you get fastboot/download mode working.

Hi Vishesh,
Were you able to rectify the problem and and update the phone ? I am facing the same problem with my g4 H815
hi.
1.
propably it's too late now to ask this and search box doesn't really help nowdays since it gives me thousands of results.
when we flash a kdz to update our firmware, modem and bootloader , our bootloader locks again and we need to contact LG to unlock it ?
if yes,
~we can use the same unlock.bin from before or we definately contact LG again ?
2.
is there any other way to update the firmware, modem and bootloader without flashing the whole kdz ?
~maybe if there is any way on linux we can extract the kdz and get the .img files ?
~maybe a tool that gives us a choice what to flash from the kdz like the mtk devices have (the mtk devices don't use kdz, we already have the .img files) ?
flashing genysis rom for example, i saw it was flashing bootloader, modem, etc. Is it possible genysis rom to be able to update our firmware, modem and bootloader ?
And sorry ! Close to 1 and half years or more to ask this question but i really need it to be cleared for me and everyone and i will edit the title later properly if there is a way so that everyone can find it with the search box.

in my case of h811 it stays always unlocked . the best way to upgrade is to do a KDZ. thats a clean installaion. selecting the refurbished option. so it wipes everything.

Oh very nice. It stays unlocked ? Great. That's what I needed to know.
Then kdz or other method doesn't matter.

but us h811 dont need .bin file. all am saying for h811 we just enter command thats it. no bin file request. and i think it should be unlocked. maybe if LG changes board or something inside then yes it would be locked. am just guessing.
Hello guys I have H815 and I can't proceed with unlocking bootloader cause my phone cannot boot into bootloader/fastboot mode. I'm not newbie, but with this phone everything goes ****ing different than in instruction.
I the instruction there is adb reboot bootloader. Of course my phone is seen in adb mode but after this command it just reboot to system. I tried also key combinations with no luck...
What to do?
My system is android 6

Hi,
I'm the same...
looking for solution I found this on Youtube:
Pratically, you have to press vol up while connect USB on PC....
I haven't the G4 with my today and so I cannot test if this is a valid mode...
If you do this, let me know if you can enter in fastboot mode

I did that and yeah it entered this mode but it's not valid bootloader/fastboot mode. It's some service mode to update firmware. Anyway it's not visible in pc as a normal fastboot and I cannot proceed further with unlocking bootloader...
Edit: it's download mode... So as I said it's not fastboot mode.
Anyone can help?
Seriously nobody? I thought this phone has good community and support...
I'm facing the exact same problem with my H810 on 6.0. Sick of not being able to root atleast.
Seriously hasn't anyone on earth found a way to boot this **** in fastboot? I mean there are a number of tutorials but everything goes different as F*** with this thing. Hope someone will update with good news. :fingers-crossed::fingers-crossed:

Thanks yeah I checked but that's for ARB<=2 devices. I forgot to mention earlier this godforsaken thing is ARB3.
I have an H811 (T-Mo) running firmware H81120p, ARB3. Doesn't seem to be much that can be done with it as far as rooting. It also has no stock recovery, only boots to system.
you did follow this official guide right? it unlocked mine after a few angry moments
http://developer.lge.com/resource/mobile/RetrieveBootloader.dev
use minimal ADB https://forum.xda-developers.com/showthread.php?t=2317790
Only way to boot twrp later is to use fastboot with ADB, recovery with buttons doesn't work.
if the device wont boot a rom use adb to get back in recovery.
if you use bank apps, install magisk before installing rom, do not get SU

Only problem is that the info linked to above applies to ONE G4 variant only - the H815 international model. The rest of us are SOL. The bootloader on US carrier G4 - AT&T, T-Mo, VzW, etc (most later firmware revisions for G3 as well) models has been nailed down. The only exception is a G4 with ARB <= 2 can be hacked with UsU in order to root it and install a custom recovery.

Tmo is very easy
Go to dev options and enable adb
Then run "adb reboot bootloader"
Once there, run "fastboot oem unlock" and voila, you have an officially unlocked bootloader with no restrictions related to UsU
Please be aware the above will factory reset your device

Do you know anyone who has done it with H81120o or later? I've seen posts for two yrs about doing it that way, but I don't remember reading about it being done on 20o or later.

Why v20o
Remember, this has nothing to do with UsU and therefore ARB etc doesn't matter
Edit: ps there are loads of H811 users in my Lineage thread and the other ROMs too

Got it. Guess that it makes sense. ARB prevents rolling back to earlier release than 20o, I'm ok. Will try the BL unlock today then.

I actually managed to get my LG V20 F800L into same situation after messing up my rooting process.
First i was stuck at logo and factory reset did nothing. Bootloader was working then.
Then i downloaded new firmware through "Download Mode", and after that i lost access to bootloader.
I know the phone model is different, but process seems to be very similar for all LG devices.
Trying to troubleshoot that atm, if i'll have results i'll post them here.
P.S. I know original poster long left (probably after throwing phone into a grinder), but maybe for someone with same problem as us in the future the info will be useful.

Ok, now i have to reply to my own post, since i believe i understand now something important:
LG phones usually dont have bootloader open to access. Until you use some exploits to do so.
I did not know that at the time of writing that reply.

bootloader unlock code different from frp unlock code.
installing other device firmware has chance to replace oeminfo.img partition. Changing this partitin often causes locked frp.
If lucky you can wipe from the erecovery that is loading. maybe even couple times. Then maybe it will boot. Other that that there has been no public mention of any fix.
do your best to fix it using hisuite or other methods if you can. if you have twrp that can help if you have stock recovery and locked frp your only hope might be hisuite and if that fails you will need a paid option like dc-phoenix or funkyhuewei. i only have experience with dc-phoenix, and it did fix my locked frp completely bricked phone, but i read that funky also works well but is nearly 3 times as expensive. (15€ vs 50€)

I know each device has it's own proceedure to, flash and all, and they are similar but different.
So can be confussing
I entered my device info (European G8s) on the LG bootloader unlock page and they actually sent me a key
I flashed it and the bootloader is now unlocked.
Are there any custom recoveries for the G8 so I can root it?

You can root without twrp in fastboot. No custom ROMs because most people can't unlock bl...
Just tried with my LMG820QM. Does not work. I was hoping it would because the G8s isn't on the list either.
Thank you.

I can't manage to unpack the KDZ and get to the img but I would really love to get root already

How do you lock the bootloader?
I bought an unlocked LG G8 ThinQ US Cellular version here in HK. Works perfectly fine but I receive the bootloader is unlocked message when loading up. As a result (or at least I think it's linked), when I try and install any banking app for Citibank on my phone, it insists my phone is rooted and I cannot use it. I have checked with as many different apps as possible and they all insist that the phone is not rooted. I don't need/want the phone to be rooted and I want the banking app to work on my phone, so I am trying to lock the bootloader. Apparently, this is doable using ADB and loading in fastboot, unfortunately, I cannot load the phone into fastboot mode. Any ideas on how I can lock the bootloader as it's not clear how it was unlocked in the first place? The version I have is LMT600US.
Also, if anyone knows whether locking the bootloader will somehow render my phone unusable - that would also be helpful as I clearly don't want to do that? :good:

Well, you can first try to install magisk manager and try to enable magisk hide (the default settings for play services and for your banking apps). If it says you don't have magisk, make sure you try and backup your boot img first and then click direct install. You can also hide magisk manager in settings. If you still don't pass safety net, clear data for Google apps and look up the pxl4xlprops module
I have an LM-G810EAW with Android 10 (V20a-EEA-XX) and tried to unlock the bootloader. Got unlock.bin from LG and tried to flash it, but got the message:

Sending 'unlock' (1 KB) OKAY [ 0.009s]
Writing 'unlock' FAILED (remote: 'Flashing Unlock is not allowed')
