THANKS!!!

Thanks a million for divulging this method, I just rooted my LG G4 H815P ZAF (South African variant), had to downgrade from Marshmallow to Lollipop first... Still, the process is pretty straight forward for anyone that has hung around this sort of dev/tech forums or has flashed any other phone before, just need to take it slow and read the steps as many times as needed so that you can do things well and in the right order... Still, it worked at my 1st attempt, so I'm really glad.
THANKS AGAIN!!!

Since I'm here, I'm going to ask, is it possible to install a recovery image, cause for what I read around while I was still looking for a way to root the phone while I was still on Marshmallow, you can only install a recovery image if the bootloader is unlocked, and even though the phone is now rooted... The bootloader is still locked, correct??
I only ask cause I wasn't able to look around yet, but I'm going to start looking for it, the only reason I rooted the phone was because there are some apps I want to use that require root access (like some vpn sharing hotspot apps), but also cause I'm curious to try the Android 7.0 Nougat, via CyanogenMod, even though I'm quite happy with the Marshmallow and even Lollipop performances.

Thanks everyone that contributed with valuable info!!
If anyone has this same model as I, is having trouble rooting, and needs any help, I'll be glad to help with some tips.

Cheers!!!

You are correct, the bootloader is still locked so you wouldn't be able to root marshmallow or install a custom recovery for CM14. However, it's possible our bootloader will be unlocked in time. One developer is claiming to have found the method and is currently working on making it work for all variants.

Thanks for confirming it!! So basically... Rooting LL on the H815P, it's useless ATM, at least that's what I felt like so far... I haven't been able to get anything that I wanted...
It's great news though that there's a DEV trying to find a universal unlock Method for all G4, that way, no one will feel left out if it works!! It's ridiculous that LG doesn't offer to unlock all devices of the same Line/Model, after all, all pay about the same and buy the same model, but only some get to have unlock bootloader??? Especially when you think that H815 (Internation) and H815P (and other region variants) are the exact same device hardware Wise, even the H815 KDZ works on the H815P... Hum... Now that I mention it... Do you think that if we flash a H815 KDZ on a compatible variant, we'll be able unlock the device via the LG official unlock site..? hum... probably not, cause it's based on device ID, not firmware... The ID will reveal the variant...
Going to try @BySezerSimsek's Genisys ROM 4.8 Which works for locked Bootloader and is based on MM, seems to be a really nice ROM.

Do you have a link to the quote by the dev you mentioned?

You are right.
I hope that we don't have to wait too long.
As we can see it takes a lot of time because he hasn't finished it yet.
And after his release it also takes some time to get a recovery working on our (H818P) phones + some custom Roms.
So let's hope he is successfully finishes this project soon.

Good day,

Have a Canadian LG G4 H812 and want to do a system image for backup purposes. I've followed all steps, drivers installed, proper com number etc however after doing this step:

H812 Canada (All H812s) : Code: dd if=/data/media/0/rootedsystem.img bs=8192 seek=65536 count=548352 of=/dev/block/mmcblk0

...it always gives a fail. Have people had luck making a system image via this method for a Canadian H812?

Thanks

Never was, always MM. I believe I might have just been told the answer today and it was 812 people CANNOT take a system image. (just to state I'm not referring to MM root, only my 812 and taking an image)

thanks
In either case this flashing a system rooted image on a MM device, will fail and probably brick the device

Yes that is what I believe as well.

It was my understanding that canucks flash 812 lp stock and then over that flash 812 lp root. (appropriate versions of course) To go back just flash mm 812 stock (appropriate version) and people have had much success with this method. This is my plan of attack. I was only attempting to create a stock image of my phone before I do anything to it.
