How to root the European LG V40 without issues? - LG V40 Questions & Answers

Hey all! I'm wondering if there's a straightforward guide to unlock, flash TWRP and root (magisk) on the European LG V40. The fora I read are mostly about the US model, and I read many issues with partitions and the enforcing thing. What does the enforcing mean exactly?
I just want to have magisk with root on stock rom. I guess I won't be able to have OTA updates when done that, right?
So if you have an European LG V40 could you maybe help me to successfully root the V40? If so, I'm gonna buy one (wanted to be sure first).
Thanks!

That I'm aware of the EBW V40 from Europe is the only one with official unlock support from LG...

Simply use fastboot to flash TWRP .-. since you have access to Fastboot out of box...also SGC Marcus has the EBW European variant as well

What if I have the same version but when trying to go to fastboot it simply reboots ?

Then it sounds like either 1) how you're trying to go to fastboot is wrong, or 2) you don't actually have the same version...

Is the bootloader unlocked or no?

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.)

I did the crossflash of my lg v40 to the US unlocked pie V405UA20a very very simply without unlocking bootloader, root or some other step. Everything works great, my imei was not deleted, nor my serial number. just flash the kdz by installing lgup and ... can i help you to do the crossflash
Everything works perfect but there is no option for Wi-Fi calls? someone knows?

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***
Downloads:

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

You sure you used the right one? You can get it in the Sprint g8 bl unlock thread, or the other one for models with kdzs by me (forgot title)
Only tried the one from bootloader unlock thread for ones with kdzs. And thanks for that one btw. Lol

hmmmm, no, I don't think so. But why would you want to even try? When we have the engineering abl, which has fastboot, which can easily unlock the bootloader?

Ahhh sorry may have misunderstood your wording. You don't use 'edl mode' to unlock the boot loader. You DO use edl to flash the engineering abl to then use FASTBOOT to unlock the boot loader.
But that may have been what u meant. So yes, use edl to flash the eng abl, then use it (fastboot) to unlock the boot loader. Yes, it will work with 409n, but any time u unlock the boot loader, user data gets wiped. Nothing you can do about that.
cheers

As far as I know u can, I've had both 409n 30e and an older version of ebw on my device - think it was 30b UK. Although there is some talk recently on tele group indicating LG has done some things with newer roms to stop crossflashing. I'd check there first.

I'd suggest you find threads about crossflashing and reading the posts about problems people have come across when doing so (you can even search within the threads for specific things like imei).
Your approach seems to be 'ask for help how to do it, then cry when it doesn't work exactly as you want'.
Many people have posted in threads here about losing imei, and what they've done to fix it. Read them. It's not anyone elses job to do it for you.

Question Orange State - NE2213

Hello,
After upgrading my op 10 pro to C.22 it started to show a message on boot: Orange State (Screenshot).
Bootloader unlocked and rooted.
Is there any way to remove it?
i cant be sure. but i would assume it is a cross-flashed device, and something in the new bootloader does not like a mismatch somewhere.
i have no information or proof or anything to confirm this, just a random thought i had.

You mean if I rollback and try again it would solve?
Would someone share the update files to C22 for NE2213 plz?
It affects all models. This popped up on the Chinese op forum and I was wondering wtf they were blabbing about until I updated my 2215. This is normal on all previous op devices. Not seeing it was odd when I rooted.
I got the same message when upgraded to C22 on NE2215 from setting update.
i had the same problem when i updated to c22. after a moment of confusion i used adb relock the device and the orange line disappeared kkk

It won't brick if nothing of system was changed I've always unlocked previous devices and relocked them with no issues. As long as it's not rooted or system changed.
