Is your boot loader unlocked then you will get trwp installed....

Think only H811 & H815 can have unlocked BL, but a quick search in the thread turns up
https://forum.xda-developers.com/g4/help/how-to-downgrade-root-rogers-h812-t3431724
Apparently that works to get just root on LP H812.

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

You're right. I need help rooting, its just every guide i saw on rooting the EU version does the bootloader unlock thing. i didnt know one could root the phone without unlocking the bl. Thanks for the link, i'm working on it now..

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!

Rooting H815 V20c-SEA-XX?

After searching all day, I can't find a complete answer, can I root my H815 SEA model?
1. it is not a European model, so the boot-loader is unlockable, already checked on lg site.
2. I've been looking for a rooted system image but there are only for older lollipop versions, can anyone share updated rooted system for v20c?
Have you unlocked the bootloader ?
Because just now i tried the same thing for my h815 SEA version and it cannot be unlocked
sorry, i am missing the huge NOT word in the first sentence, the bootloader is not unlockable unfortunately
Are you sure? This post is very old and says that you can unlock your bootloader
http://forum.xda-developers.com/g4/general/psa-official-lg-bootloader-unlock-815-t3233391
im sure
I have the same problem here... :crying:crying:
any progress on rooting this variant/version?? I was disappointed to find my phone is bootloader locked...

Rooting H815T Marshmallow

Hey all. So basically I recently purchased the H815T Australian optus model. It was initially on Lollipop but updated to MM & I need root so I can restore all my data from my previous device but seems I need to unlock the bootloader. Unfortunately it couldn't be done because the H815T isn't supported on the LG unlocking website. Is there another way to unlock the bootloader or rooting it? Please help guys, I really need to retrieve my data but can't do so till there is a method to root. Or would I have to downgrade to Lollipop & root? I'd immensely appreciate some assistance with this, cheers.

Thanks for your help. I really enjoy being on Marshmallow so don't really want to downgrade. Thankfully I got most of my whatsapp messages through google drive backup & most of the other apps did have some form of cloud storage. I'm gonna stick to MM till a rooting method does eventuate.

[H812] Possibility of flashing H815 or H811?

Does anyone know if it's possible to have the H815 or H811 firmware on the H812 (Canadian version)?
I want to root my phone, but alas the Canadian LG G4 cannot unlock bootloader.
I'm fairly new to rooting and flashing, so any help is appreciated!

No that would hard brick your device.
You CAN unlock the h812 though by UsU.

follow SteadfasterX instrustions to unlock bootloader. UsU. It works! I did it. Now I can install h811 ROMS on my canadian h812!
Will I be able to flash custom ROMs on it afterwards? While researching, I couldn't find any custom ROMs that were available for the H812.

During the bootloader unlock process it tells you what firmware your device is compatible with. Mine said h811. yours will probably be the same.
Cool! I'll try it out sometime and see how it goes. Thank you two so much!

Hello again,
Which ROMs were you able to install? I tried using Genisys, but I can't even use the touch screen, let alone use it as my daily driver.

Suggest you close this thread and move over to steadfasterX's bootloader unlock thread - in the search bar there search for H812. All the roms are in the OP in the Downloads section. There is an AOSCP N specifically for the H812.
Are you sure you have followed ALL the instructions to unlock the bootloader using usu? Maybe you missed a step? I'm using the h811 ROM from this thread... Genisys. Daily driver, no glitches. It works flawlessly. Check the usu instructions again. I think you missed a step. It wasn't a quick easy thing. I made a bootable flash drive using steadfasterX's FWUL Linux distribution and used the tools on that... Takes about an hour to get to Twrp and flashing ROMs.

This is the one I'm using... https://host.llamasweet.tech/genesixx/LineageOS/h811/
I can't even tell you enough how valuable the tools and instructions from steadfasterX are for installing TWRP on the canadian LG G4. there is no other way. SteadfasterX spend a lot of time and energy developing the tools and the instructions to make it work. He should get some kind of gold metal for saving all the useless canadian G4's from going to landfill without updates!

LG G4 VS986 Root question. 2BA or 13B

Hey guys. I had a VS986 back when it was 13B and all I did was downgrade to stock with LGUP and i flashed a rooted stock room, i remember doing something with chainfire "Flashfire" at the time because there is a locked bootloader issue and a custom recovery is not available..?|
Well now i have a new LG G4 VS986 that is 2BA. Can I root the 2BA or do i need to use the LGUP to downgrade to a specific version (like 13b?). And then what is the rooting procedure? YES, I tried to look it up, but i havent been following development for so long I am out of the loop and so much info from the gate is ALOT to take in.
So can someone PLEASE give me a quick run down of the rooting VS986_2BA procedure, and I can figure it out from there- Im not asking anyone to do the work for me, just alittle help. Or a link that could point me in the correct direction. I just dont want to have a new brick! Thank you!!
If you want to root 2ba you need to unlock the bootloader
https://forum.xda-developers.com/g4/general/unlock-unlock-lg-g4-device-usu-t3760451
Make sure you read the instructions and warnings because the bootloader unlock is permanent!!
Do not flash the baceband packeage you don't need it and your SIM won't be detected after flash
After you do that you should know how to get to fast boot mode and you need to flash this patch boot imge https://drive.google.com/file/d/1GH00BeWsEtKE2Ea34dXLmeMUC4Ts8XEI/view?usp=drivesdk
Here's the command
Fastboot flash boot (filename).img
And that's it all you have to do is install Magisk Manager from the play store
If you need any help please quote me

Not as of March 2018. https://forum.xda-developers.com/g4/general/unlock-unlock-lg-g4-device-usu-t3760451
I did it to my Verizon LG G4 and am now on Marshmallow, rooted by Magisk, and running XPosed. It's not a "double-click, next, next, finish" process. Read the entire OP in that link. And here is my summary of what I did https://forum.xda-developers.com/showpost.php?p=76691955&postcount=1063.
Oh wow that's awesome, I didn't know that was possible. But since you personally confirm it then I'm going to check out those links!
I wish I knew about this a month ago, I just downgraded mine and my girlfriends phones and flashed the rooted 13b system images.
Thanks for the info! ?
