H815 USA Any working root + TWRP installation method ? - G4 Q&A, Help & Troubleshooting

I have an LG H815 USA version. I have updated to MM using KDZ and LGUP method. I am not rooted and I can't seem to find a method to root and install TWRP on this device. All methods require "Unlocked bootloader" but H815 USA does not have an unlocked bootloader (not yet ).
So how do I proceed ? is there a method ? maybe downgrade back to LP and there is some method for perm-root and custom recovery installation ?

Nope need the bootloader unlocked, so i think your luck is out

1. Flash the 10C KDZ using the "LG Flash Tool" and method in this thread
http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
(you will have now lost TWRP and root)
2. Re-install TWRP and install Supersu following the method you originally followed
Thanks..

And disable automated ota updates when you're finished if you don't want this to happen again.

3. and NEVER EVER take an OTA update when rooted or bootloader unlocked
I recommend after each update to make clean install
has anyone with the SEA variant tried flashing the Euro Open KDZ? They are both h815 so it should be fine right?

If I downgrade to Lollipop from Marshmallow can I root?

Hi Guys,
I tried rooting my Marhsmallow LG G4 now and I couldn't get passed the step where you type in "ID" in accordance with this guide: http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765.
I read somewhere that it was because I upgraded to MarshMallow.
Now - I want to know - If I downgrade to Lollipop can I follow the above root again and it will work?
Thanks!
Yeah.its possible. I returned lollipop from mm using LG up. Used to inject root and I'm using currently my g4 with root access.my recommend try to inject root. You don't need to open bootloader lock.

Does the method of loading a rotted kdz still work? I am wondering if I can do this with a Canadian H812 that was updated to M?

LG G4 Best root method?

Looking for the best available root for the lg g4 marshmallow international version, even a 1 click method
If you searched you'll realise there's no root for locked bootloader G4s on MM.

He said international dude... The H815 which has unlocked boot loader. Very useful reply. But I too need to know the best method.

What? H815SEA and H815EU are both international variants but only H815EU can be unlocked.
The best method is to flash boot.img unpacked from the custom kernel like SimpleGX via fastboot that will allow you to further flash TWRP in which you'll flash full kernel package to avoid software problems and lastly SuperSU
the method i followed was-
1. boot into twrp recovery with adb command(you need to have the twrp.img file in PC and also copy it in internal memory of your phone with SU)
2. flash systemless root with twrp
3. reboot
4. install flashify
5.flash twrp.img from your phone.
6. done
but there aren't as much benefits of rooting as any other phone. viper4android doesn't work. spirit fm doesn't work. xposed doesn't work properly.(these 3 were the main reasons for which i rooted)

Cyanogenmod Bootloader Help

I recently Rooted my LG G4. I did it using the RootJunkys video using Download Mode and Coms etc
I am successfully rooted. Have TWRP Installed
(Never unlocked Bootloader) (Video didn't show)
Now whenever I try and Flash CM13 I get "Error Executing Binaries etc"
I read it's due to incompatible Bootloader.
Would my bootloader not being unlocked be the issue? If so is there any tutorial how to Unlock Bootloader.
Running 1110N Software Version
How did you even managed to install twrp? The bootloader unlocked is a must. But only H815 can be bootloader unlocked, if you don't have h815 you have to wait until our Devs find different way to unlock it
I used Flashify. To Install TWRP
For Root I used COM Port and Command Prompt while Phone was in Download Mode

Dude you are posting in the wrong forum. You are on old firmware you need to update to the new marshmallow firmware for CM13. Go to the T-Mobile G4 forum and follow the instructions in autoprimes 20i thread.

Lg g3 d855 v30n twrp

Hi,
i want to get TWRP on my LG G3 D855 with Android 6.0 and Software-Version V30n (latest version, i do all updates when they was available).
I know that i must unlock my bootloader, but all information to do that is older that 1 or 2 years. (something like that: https://www.xda-developers.com/lg-g3-locked-bootloader-bump-xdatv/ )
Is it possible to use this guide with my Software-Version?
If i unlock the bootloader with this method, is it possible to install TWRP and root it with this guide ( https://www.getdroidtips.com/twrp-recovery-lg-g3-d855/#comment-1948 ) ?
I never done that before with any Android device, so i am a noob.
Sorry for my bad English and thank's for helping me.
You need to downgrade first to version 30j, 30f, or lower to root the phone first. Then you can flash a bumped v30n zip and use it with root like magisk or supersu
Sent from my LG-G3
And what is a bumped .zip and where can i get those?
What does this .zip do if i flash it to my phone?
