First off, you do not need to necessarily unlock your bootloader to have root BUT you do need to have an unlocked bootloader and a custom recovery in order to flash custom roms.
Check out steadfasterX's thread to unofficially unlock your bootloader here: [UNLOCK][UNOFFICIAL][G4] Unlock **ANY** LG G4 device with UsU
- the caveat is that you must be on or be able to downgrade to MM and have an ARB of 2 or less. Use SALT to ascertain your ARB version and to back up your MM stock rom (important!).
Then read thoroughly (everything, including the FAQ's) and make sure you understand fully the directions in the OP of the UsU unlock thread before proceeding to unlock ... and ... learn to use the Thanks button at the bottom right of the post where an XDA member is trying to help or guide you - it's an XDA courtesy.

You could refer to: Root ANY LG G4 Variant 100% Success Directives | Root Injection | Less Bricks
Use the search function, putting in your phone model, in the thread to get specific relevant posts to find any issues/problems. IMO, I would go the UsU unlock method, if you're able to ... and then root.

No video that I'm aware of. You don't know your network carrier? Go to Settings > Network & Internet > Mobile network > Advanced > Access point names (APN's).
You can unlock your bootloader with steadfasterX's UsU method: https://forum.xda-developers.com/g4/general/unlock-unlock-lg-g4-device-usu-t3760451 ...

LG G4 H815P - Need help rooting

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!

i have not use this one but its similar.. i used for h811 system image... on mine i had to be on LP 10n not sure aabout your variant... then copy the system image file ... its a 4.2GB file then put phone into download.. i opened folder and do a comand promt in there.. follow the commands and it moves the system image enter leave and it restarts with root on the phone....
like i said this is for the tmobile h811.. but its similar to this guide never done this guide so follow their steps..... good luck
First of all thank you for sharing this Im afraid i might brick ny device i thought there was some easy method like CF Auto root one click n done ... I Have to wait for bootloader to unlock i cant risk or is there any easy method flashfire?

i know i did mine too.. i was afraid too.. but there was an eaiser way for my h811.. its the same but it only talks about that phone... but it should be similar..
Theres no one click methods unless bootloaders unlocked which dont look like is ever gonna happen. As long as you follow the steps ure pretty safe.
NOTE THIS IS GOR TMOBILE ONLY H811
just read and since its shorter maybe you can get an idea on what to do with the other method .. this guy says to read the low effort as its the same....

seems like you may have the G4 that cant be unlocked.. so thers no way.... you could root and install xposed but on LP only... with locked bootloader.. only a few h815 from some countries can be unlocked..

Just got an LG G4

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.

The problem is that all unlocking tutorials ask me to "enable oem unlock" but when I cannot do that. I would appreciate if you can give me a direct link to tutorial that will work for my phone .
