Use this alone with LGUP
Your to pick "upgrade" option and select stock lollipop kdz then change to "refurbish".

After trying several tutorials, i found out that i cannot unlock my bootloader. I thought that my 815p could pass for an 815 but no.
I also looked for specific info on rooting this variant but it seems its not common enough. Can someone direct me?

use the same method as 815 EU. i'm using 815P from south africa and you can root it so easily with the low effort root. choose the 815 EU/international command

I get what you are saying, but all the guides i saw mentioning the 815 EU do the unlocking bootloader step. When i go to the official lg site after getting the info from fastboot, i get a message along the lines of "your model is not supported".
Can you link me to the guide you used, if possible? How did you unlock your bootloader?

not unlocking bootloader... your heading says "Need help rooting". you can root the H815P but can not unlock the bootloader. i'll paste the link for the low effort as they came up with it.
http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
only for Lollipop (android V5)
rooting it is exactly as the H815 EU version.
get the Send_Command files
get the rooted system.img
connect your phone
type in the commands to verify connection
type in the dd commands for H815
your done and phone is rooted and can install all Lollipop ROMS

great thread.. thank you! Did it work for you?
it did
Guys I was able to root the H815P: First I flashed it with 5.1 (it had android 6), and I flashed it with H815.. not the "p"..
Then I was easily able to root it with that dd command.. smooth!
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.

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,
I just bought a t mobile LG G4 from market here in Pakistan. its software version is H811-10n. My sim is working fine in it so it must be unlocked. Now I want to remove the bloatware but in order to do that I need to root the device.
To root the first step is to "enable oem unlock" however when I go to developer options and click on it and then click enable, nothing happens. A tick never appear in the box next to "Enable OEM unlock"
Can somebody tell me what am I doing wrong.
jeje, there is a lot of info, is not as easy as activating oem unlock, just make some research. it is a sticky thread

to roo it theres 2 ways. one with locked bootloader. that you need to be on lollipop. i suggest lollipop 10n .kdz
on h811 we have antirollback means once you are in specific version you cant downgrade or you brick phone.
so if you want to have it unlocked bootloader. and want to stay in lollipop and marshmallow you can use either one lollipop 10n and MM 20i.. they both version antirollback v2 so you can switch between MM or LP.
for root and twrp bootloader unlock . fisrt you must flash KDZ 20i. from there you unclok bootloader. the root and install twrp.. and i think you can use lollipop 10n and rooted never done this though... or if you dont care about lollipop use the latest MM 20p. kdz thats V3 once you there you cant go back to 20i or lower only to 20o.

I'm on marshmallow 6.0
Dont know what is LGUP =/
Lgup is a program to write kdz file into lg g4. On MM you cannot simply access the phone with Send_Command.exe, you have to use lgup, that will open a port, the pull the cable and stop the lgup program. After that send_command.exe will work.
But you will not be able to root, as without unlock bootloader there is no root on MM.

There is a tool by LG that lets you flash approved firmwares only. LGFlashTool2014.exe or something like that.
The luck was that I have an old KDZ I found around on the internet, which has lollypop and allowed me to flash an older version.
The name of the firmware was "H815L 10F.kdz"

Those codes are ROM dependent and you're using a brand new version (nougat for your device is just a few weeks old)
Maybe try
