Is the bootloader unlocked or no?

On the tmo lg g4

Yes. Enable OEM unlock on the dev options.

With the TMO version unlocked you'd think we'd have a simpler root method than flashing the entire /system partition, wouldn't you?

Great. Thanks

G4 newbie here, so the bootloader is fully unlocked on the T-Mobile version then? You don't have to do the official LG Developer unlock method that currently only the 815 EUR model can do?
When ROMs drop, you have full access to the phone? Just want to confirm, I had a non EUR model on AT&T that worked great, but was sick of not having any access to the system. Does the H811 have the bands required for AT&T?

Fully unlocked. No LG dev stuff.

Question to anyone willing to answer:
How did people figure out that enabling OEM unlock made the bootloader be unlocked on the T-Mobile variant? I'm wondering because we have very little info on the H812 variant to determine if this technique would work. And please don't give me that canned answer "IT ONLY WORKS ON H815 and H811", as I know what I'm doing... I just want to understand why the H811 T-Mobile is different and if other more obscure variants could also have this solution.
Thanks!

I Attempted to flash the twrp one click recovery to my friends LG G4 H811 TMOBILE, I went to developer mode, checked the box to OEM UNLOCK, and whenever the phone reboots to Fastboot or Download mode, if done by the H811 one click bat script, the phone only reboots regularly, if i manually adb reboot-fastboot then the screen shows a barcode, and the phones IMEI number. Whats up with this?

If you want root H81110N, just go this route. Much easier and works. http://forum.xda-developers.com/tmobile-g4/development/h81110n-stock-rooted-image-t3191038

The H811 Tmo is different because the carrier, TMO, decided to allow it to be unlocked. That is pretty much all there is to it. I am sure that is frustrating to non H815 and H811 owners.

The first post in that thread says:
"T-Mobile USA LG G4 H811 10H. WILL NOT WORK ON 10N."
I have the 10N. I also don't have a Windows computer. Where can I find instructions for obtaining root? (I prefer a manual method using Linux commands if possible.)

LG G4 ZVB

I got a phone for a deal from a friend today in hopes to unlock it to use with my Cricket Sim card. Well i am new to all of this but notice its running Android 6.0 or ZVB and see its a Death Trap.... ????
Does this mean the phone is not able to be rooted and Carrier unlocked since its ZVB ?

please help guys

Unfortunately there is an anti roll back mechanism in ZVB, meaning you will not be able to go back to ZVA, ZV9 nor ZV6 which is the version I know it can be rooted. You may find more information here. Now Sprint can unlock it for free, you just need an account with them (cell number) and they gladly help you at no expenses.

I called Sprintbonce i read about the ZVB junk and they required a security pin
Do you kniw if it must be a Sprint customer to get help withbit or has to be the recent user ?

Yes, you will of course need the original owner, which if you did buy it from a friend, should be nbd.

You can use basic flasher/dfs to get the spc and unlock.

I flashed mellow mallow rom as i was in zvb already from OTA. I turned on airplane mode after i turned it off radio didnt turn on anymore. Tried alot of things still nothing. Sprint lock phone info so i cant turn manually. It also says unable to control device radio. So i flashed global MM and now it does not ask for my pin. I thought maybe i can use some tool or a comand to force turn it on. Maybe its sprint blocking my phone even thought ESN check online seems clear. any idea ?

TOT back to Sprint ZVB factory firmware?

only thing that comes to my mind is that your phone is not a h811......
plastic and software says it is. but maybe your motherboard could be h810...
if you cant find a fix for this.. open it up search for dissasembled video of LG G4 and take motherboard out physically.
and read the plaque variant model... maybe its not h811 thats why it might say its locked..
or return it.

So could you explain how you did the crossflash with the bootloader not being unlocked. I have LGUP installed and the US unlocked KDZ file. It failed for me.
Which guide did you use or if you care to explain the steps here. Thanks!
EDIT: Figured it out.
New question, are you able to put TWRP on your phone with current methods out there? if so, how?

Will OTA still work?

Do you mind sharing how you figured it out? I've tried doing this with my Sprint unlocked device but I have had no success so far. Device isn't recognized despite downloading LG Mobile Drivers.

Yes. I'm not very good in English and I do not know how to create a guide here in XDA. But give me a chance and I'll try

[Guide]
I am not responsible if something goes wrong.
everything works perfect with total comptability, but I can't confirm if fastboot can be accessed after crossflash. Also, there is no option of wifi calling or calling plus, I cannot confirm OTA, because I installed android pie and it is the latest version for US unlocked. ***Maybe if you install the latest android 8 oreo before ,then you can test if ota works***

firmware: https://lg-firmwares.com/lg-lmv405qa-firmwares/#tab=firmwares
*rename the firmware file to pie.kdz and put in desktop*
install lg usb drivers (be sure your device can adb. enable usb debugging, open command and put adb devices. check notification on the device and hit always. also Switch between all USB connection modes from the mobile so that Windows installs all the drivers
install lg up
Put LGUP_command.dll it into the folder: C:\Program Files (x86)\LG Electronics\LGUP\model\common ( if there is no common folder, create one and put the file there )
now...
put device in download mode
power off device
connect usb cable to pc, but not the phone
Hold and keep phone volume up
Plug your USB Cable to your phone while holding volume up, already in download mode, release volume up button
now go to device manager an check in ports/lge the value number for example com3, save it
Then go back to C:\Program Files (x86)\LG Electronics\LGUP
Hold the shift key and right click on a free space.
Choose to open a command prompt or PowerShell in Windows 10
After oppening it, type cmd and hit enter.
now you need to put this
lgup_cmd.exe com3 “C:\Program Files (x86)\LG Electronics\LGUP\model\common\LGUP_Common.dll” “C:\Users\your desktop username\Desktop\pie.kdz
and hit enter, but need to change the com number value. for example mine was com3. if yours is com2, com5 or another just change the number.
and that is. if you do it right then it will start flashing and you will see the progress on the mobile and the powershell

Ok so I just upgraded to android 11 and want to unlock the bootloader but while doing it through the app it says failed to unlock the device why is that?
Also I have never unlocked my device before it's the first time I'm trying to do so..

Do a backup of your data you don't wanna loose and flash raw file with A10 available here in ROG3 section. Then your unlock tool will work. After you unlock you can update and restore data. Bootloader remains open until you lock it again with abd or app.
