Im super new to rooting in general, and the guides here have so much information and I don't really get most of it
My LG G4 is Verizon on VS9862BA on Android 6.0.
So I have a lot of questions:
Whats the difference between unlocking the bootloader and rooting
What comes first unlocking the bootloader or rooting
How do I get TWRP on my phone and do I get it first before unlocking the bootloader and rooting
What are KDZ / TOT, ARBS, Salt, QFIL and Bootloader stacks, flashing, fastboot mode, fastboot flash, fastboot boot
(Was looking at steadfasterX unlock guide and I have no clue what any of these things mean)
I have no clue what to do but I'm really interested in rooting, just super confused on everything and trying to be careful

so rooting the latest FW requires unlocking the bootloader.
unlocking the bootloader allows you to run unsigned code on boot (for an example rooted FW or custom FW)
exclamation for rooting:
so there are different types of user privileges on Android or any Linux. the most important one is root. the root user has full read/write access to the / directory (so pretty much everything ) and can run any command since they have all the privileges. The user you are login to on android does not come with root privileges. so what the term rooting your phone means you have the capability to call an app to run under the root user. (if this helps, its similar to running the sudo command on Linux or for windows granting an app administrator access to run. )
kdzs are the FW files that you flash from download mode. you don't have to touch KDZ / TOT, files at all if you are on the latest FW or when you unlock it since you will have TWRP.
salt is the tool used to unlock the bootloader. if you don't have Linux use FWUL
fastboot mode is a bootloader mode where you can flash files and do other stuff.
you don't have to even mess with bootloader stacks since you are on the latest FW.
hopefully that helps, its kind of hard to answer everything in one shot so if you still need help just quote me.

Now since our Lg g4 has been recently rooted how can we install twrp on the h815 without the bootloader being unlocked?
You can't flash TWRP without unlocked bootloader.
Can't root access unlock the bootloader?
Pardon my ignorance of the platform, but can't root access be used somehow to unlock the bootloader? How is it locked?
On a related note, is there a simplified explanation somewhere of all the various layers of the Android experience? I have at least a basic understanding of the BIOS/EFI/LILO/GRUB/kernel/init boot process of a regular computer, but when I was first told about the steps required to install a custom ROM (e.g., HyperDriveOTA or CyanogenMod), it seemed confusing and much more complicated than the standard PC boot sequence. Bootloaders, recoveries, and launchers, oh my!
Thanks.
then how to unlock bootloader (non-EU 815)?
You can't unlock it. There has been no way found yet.
I have received my new LG G4 H815 (EU) phone today and I definitely want to root the phone. Now I'm asking myself whether I should unlock the bootloader or not.
As far as I understand, there are two completely different options for getting root access to the device:
1. Register on LG site, officially unlock bootloader, install TWRP image via fastboot, install root via TWRP
2. Walk through the instructions in this thread:
http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
According to the thread you should disable OTA upgrades after rooting it and there is always the possibility that LG patches this rooting method with future Android Upgrades. However, I do want to upgrade the Android system image from time to time (LG will probably provide an upgrade to Android 6.0 sooner or later). Will upgrading the Android system (without loosing root) be less problematic when I unlock the bootloader now? As far as I understand it so far, you can easily root it again after an upgrade if you have unlocked the bootloader. Is that correct? Can I still use OTA upgrades when the bootloader is unlocked and TWRP is installed? I don't mind running fastboot to reinstall TWRP after an upgrade but I don't really like to manually download each Android upgrade from shady mirror sites instead of using the official LG OTA updater.
I do know that unlocking the bootloader will void the warranty and that some Apps may refuse to work no an unlocked device. I'm ok with that and I want to have the phone permanently rooted and install updates (without loosing root) with as little trouble as possible.
Since unlocking the bootloader will wipe everything, I want to do it either now (before setting up the phone) or never. So what would you recommend?
Hi everyone.
I have honor 8 pro (DUK) which has locked bootloader and yes I know it is not possible (officially) to unlock it. I have read several threads which state that unlocking bootloader is not necessary to root your mobile. Ok that was interesting, so I have searched all alternative methods of rooting which does not require unlocking bootloader, but none of them helped.
Attempts I made:
1. Many guides show to root the device via twrp. Flashing twrp requires unlocking bootloader, so out of options.
2. Tried to flash the twrp image via adb command but i get the message 'Command not allowed'. The obvious reason could be the locked bootloader.
3 Tried with Kingoroot and King root, none of them helped.
4. Magisk is unable to flash the magisk.zip file (I don't know why) and hence unable to use magisk as well.
Any other methods to root my device. Please help me dear developers and members. I don't want any custom ROM, all I need is to root my device.
Thank You.
Following. After Huawei/Honor decided not to provide the bootloader unlocking. I do not think we can and now there is no development for this handset at all.
Yeah and its sad that we are stuck here.
Hello!
So, I've purchased a T-Mobile LG G8 ThinQ phone for use in Canada and wanted to remove the T-Mobile splash.
After reading a bit on the forums here, it seems like it'll be too complex for someone like me. (I'm lazy)
So, I uninstalled Magisk, which supposedly uninstalls root and I'm looking to relock my boot loader.
Just I'm having a hard time getting back into bootloader with the vol- and power button method, and using adb to reboot into bootloader doesn't seem to give the desired results.
The phone just reboots like normal with the unlocked bootloader warning.
Reason I wanna relock it is so that I can use Android Pay again and using Magisk Hide or the alternative would require them to give a guaranteed result.
One day it could be patched and I won't be near a PC to resolve the issue and I personally don't like carrying my wallet.

I'm not an expert (or even that experienced with phone flashing), but a li'l Googling gives this result. The relevant part being:
Re-locking the bootloader​To re-lock the bootloader:
For newer devices (2015 and higher):
fastboot flashing lock
For older devices (2014 and lower):
fastboot oem lock
Note: Re-locking the bootloading on a Motorola Xoom erases all user data (including the shared USB data).

Sure, I'll try that if you can help me figure out why I can't get back into the bootloader.
You need to use QFIL to put flash back the engineering abl file to get fastboot. Then you can run the command.

Thank you! That worked, I was flashing abl_a and abl_b with the backup images to see if that did anything.
I just followed some tutorial on youtube to unlock the bootloader and now my touch doesn't work. Please help
Well there's a lesson in there, first, don't follow any guides but the ones here on xda. Many people creating those youtube guides are following some 'generic' instructions that work for some android devices but not others (and the authors don't know which devices they work for or don't work for).
And second, I'm guessing here but did you do a backup of the partitions you changed? Did you use qfil to make the changes you made?
and last, what variant of the G8 do you have? Sprint? At&t? If it's one of those that causes additional problems, because they don't make their kdz available. Without a backup of one of those, you can't restore it.
cheers

You apparently flashed the engineering abl through the qfil, according to the manual for unlocking the bootloader. This engineering abl is needed to get into bootloader mode (for fastboot has become active). After unlocking, you need to push back the native abl_a and abl_b, did you make their backups, according to the manual?)) In general, as far as I understand, the engineering abl, it is originally from the 850th model (in the bootloader, when the engineering abl is flashed, the displayed phone model changes), but it can be used to unlock it on the 820th, but since it was originally from the 850th, so the touch does not work. thats normal. finally. after you unlock bootloader push back the native abl_a and abl_b
I followed the un-brick guide and crossflashed another kdz so now i have bootloader unlocked, root and twrp.
Thanks everyone for the help.
