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..

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?

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 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!

Bootloder unlock

How can I bootloder unlock my lg g4 "TWN"
my phone does not support bootloder unlock
so what can I do?
You can wait or do some research and write a bootloader unlock tool for everyone
...we are all waiting :/
You would probably be waiting indefinitely. It does not look like there will ever be a bootloader unlock for the G4's which are locked.

you can root yours if it is dual sim model . Forget unlocked bootloader .
My H818P is rooted with Lollipop.
But to Be honest, I'd rather have an unlocked bootloader :/
No root on MM and up is a pain.

Not sure but i think not possible, check General and development section please.
You can still root...I have h815 twn model, running 5.1 rooted...if you are on MM you need to use LGUP tool to downgrade to LP and then flash the rooted fw with flashfire...there are YouTube vids on it, just search

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 ...
