The H818 cannot be bootloader unlocked officially. It could be unlocked unofficially with steadfasterX's UsU method ... BUT... you will loose the touch screen function on your phone, rendering it basically useless. So, you are basically out of luck and I wouldn't hold your breath that it will be solved anytime soon, if ever. If you use the search box on the linked UsU thread you will see that this has been asked and answered ad nauseam and you are not alone in this. Unfortunatey, it's one of the only LG G4's suffering from this issue.

Rooting H815 with locked bootloader.

hi
I did a lot of reading here in XDA lg g4 forums and still i didn't understand if it is possible to root a g4 h815 device
while to bootloader is locked.
i tried to unlock it with no success.
My software version is V10c-SEA-XX
Model number LG-H815.
Any idea?
thank!
If you can't find the answer to this question, you should stop looking. Rooting is dangerous and can ruin your expensive new phone.

No need for sarcasm, i just want to make sure,
i read this post http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
but still i want to be 100% sure that my phone is supported...
I wasn't being sarcastic. It's my honest belief, that if you have to start a thread to ask "can I root my phone" you should be warned not to try.
bump
as long as you are on lollipop or can downgrade yes you can.
if not sure if you can doengrade enter hidden menu. search if you dont know code. go to software all the way down and check antirollback.. i heard all h815 can but better to check..
then follow this procedure i did it when my bootloader was locked for warranty.
i created a .img from my phone.

Lg g4 bootloader talk

Well i took some time to send a long email to lg and i might got somewhere. Some of you may say its not worth the time and so on but who knows lets try. Lg send me a link to there forum for devs. And i looked up the lg g4 vs986. I got 3 post. Thats it. 3. Is it worth a shot if we all post to there forum and demand a bootloader unlock for our vs986. They have a bootloader unlock for there fancy h815 phone but most of us are stuck in the dust with nothing knowing we paid $600 for this phone. Why not give us the freedom to do as we wish on our phone. It be nice to see a bootloader unlock soon so that we can have a custom recovery and all the things we want, including 6.0 that may just required a bootloader unlock. Here is the post if someone wants to start and maybe show lg to get off there a$$ and start working on a bootloader unlock if we all keep pushing the demand for it
I hope i at least helped the community here at xda. If i did help thanks just want to be part of the team

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! ?

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 ...

G7(Sim Unlocked LM-G710ULM) Bootloader unlock and/or root?

Hey guys i just got this with the ULM model and was wondering if anyone had a bootloader unlock for it. also if possible a root
There are rumors of a new bootloader unlock for G710ULM but I haven't tried it myself. If you decide to go for it let us know.
I managed to unlock my bootloader with some help from the telegram group
Yes, there's a new unlock method posted on one of the famous Russian forums. I haven't tried it, but it involves booting once with a rooted boot image, using root and a root adb terminal to overwrite the bootloader with an unlockable one, unlocking the bootloader, and copying the original boot loader back. It seems fairly straightforward, though, as I said, I've not tried it.
Yes, thats a very good explaination of it
Link to the method?

As far as I can tell the method has only been posted in the G7 Telegram group. I think I'm not allowed to link to the group invite, but if you Google for an LG G7 Telegram group you should be able to find it and get access to the group.
This thread is kind of old, but I found this thread before I found the latest and best one, which is here: https://forum.xda-developers.com/lg-g7-thinq/how-to/how-to-bootloader-unlock-g7-thinq-t-t3963568
The answer to OP is YES it is possible to unlock bootloader on ULM and other G7 models, and the instructions are in the thread above ^
