h810 has bootloader locked so no twrp... and only injecting system rooted.img. but...... not on marhsmallow you need to be on lollipop... but theres antirollback. you need to findout if you can downgrade fisrt.

Use the search function and really do not open several threads asking the same question this is not the way it works

search for how to enter hidden menu on your variant ... enter code then go to software on bottom it says antirollback i think if its 0 then you may proceed..NOTE not sure so if 0 then it means theres no antirollback..
downgrade only if you are sure you can..

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

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 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....

i assume your variant doesn affect antiroll back.. you can check this on hidden menu i think its says software info. it would say antiroll back 0-1-2-3.? not sure but on mine h811 tmobile. i can only downgrade from 10n to 20i wich both are antirollback V2. the new 20o its V3.. son once am on 20o i cant go back. this is my case. not sure about other variants but if 0 then i think you can.. better ask.. but yes you can root it only and install xposed..
ask some one about the antiroll back.. and please let me know if it doesnt matter so that next time i can help better.

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.

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
*#*#06#*#*
##06##

Can you check your anti rollback please? I don't know if the f500 has it implemented but that could be the reason.

thats very good (and so not the issue)
try to use an USB 2.0 port if u currently using a 3.0 one.. sounds still strange to me but I saw that error related to the usb port somewhere.
Besides that it could be likely a wrong msm DLL issue or you're just following the wrong guide.
I think this one should work for you too:
https://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
otherwise do a search on this error like here: https://forum.xda-developers.com/search/thread/3107848?query=0x2000
I would recommend better asking in the above thread for further help is better than going on in this thread here (has nothing to do with your original question btw... )
