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?

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 am currently on android 5.1 and I want 6.0 so I heard I can update it with lg bridge.After that I have to unlock bootloader so I can acquire root permission.Would either of them make my phone not updateable with officials(ota)?
You probably will have to manually upgrade with a KDZ file. Maybe the real question is... is it worth to unlock bootloader and lost warranty?
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.
I've asked this on Reddit already, but thought it was worthwhile to ask here as well
It's been a long time (3 years) since I had a device that I'd been able to root and I wanted to make sure I'm ready to do it on my UK 7T whenever a solution becomes available (I've checked here and it seems a bit hit and miss at the moment). In order to get my device prepped should I just unlock the bootloader and wait for someone to get TWRP and Magisk working? Basically, I want to avoid losing all my stuff in x weeks time when the process becomes safer/simpler and from memory I think unlocking the bootloader causes everything on the device to be wiped.
TLDR
2 real questions:
Does the process of rooting the device wipe it, or does that only happen when unlocking the bootloader?
If I unlock the bootloader when I first get the device, will this be me prepped for rooting later on without losing all of my data?
Thanks
If you're not going to install a custom Rom, you're prepared for root without losing your data. I did it too yesterday when my 7T arrived, right after update oxygenos.

I can't see myself moving from OOS, I just want root. So you're saying if I unlock bootloader from the off I'll be good for rooting in the future?

I'm changing from an iPhone 7+ to Oneplus 7T and got it yesterday. Why you don't make a backup when it's time for root? So far I can't see Custom ROMs or a working TWRP for the Oneplus 7T.

Yes, i lost data when unlocking the bootloader but then it was okay while rooting. I think you should unlock the bootloader and root as soon as you get the phone, but after updating to latest 10.0.4 version
Unlocked Bootloader / no Magisk Hide
Consider that apps like GooglePay or other apps will refuse working since they detect the unlocked bootloader state as possible security leak. GPay says, that due unlocked bootloader it does not want to initialze it.
So after facing this problems I would recommend, since magisk is limited to patching the actual boot.img, to stay on locked bootloader and unlock it after a secure method exists to install magisk and maybe TWRP. Otherwise, if you donot use these kind of apps, you can stay with unlocked BL.
Would there be a way to do one-click-root on the Motorola Moto G5 (XT1672) or another way that is easy and does not do a factory reset? Thanks!

I really don't know how this is going from root very well, but as I understand it, you need to unlock the bootloader of the device (which requires a factory reset). If you already have the bootloader unlocked, try KingRoot, The truth is the only root of a click that I know, I have not really tried it on this device, but on an old phone, and it worked fine. The only problem I have had and I do not know if it is the fault of the device or KingRoot, and is that when I try to uninstall an application which I gave it the root permissions, the phone restarts, to uninstall an application I had to deny it permissions and then I could uninstall it, I repeat, I do not know if it is a problem that only happens to me

Rooting the phone does not require a factory reset but unlocking the bootloader does
So if you haven't unlocked the bootloader you will have to factory reset it during the process
If the bootloader is already unlocked you do not need to factory reset your device again in order to root it
Magisk should be the only way you should root your device - do not use other methods like kingroot as this has bloat and is not systemless (meaning it alters the system partition)
You need to root with magisk in order to maintain the system partition in its original state in order to pass basic integrity & to be able to pass cts profile (may need a magisk module) and to hide the fact you are rooted from apps that will not work if your device is rooted

Thank you for your help. I tried several One-click-root, none worked, so I researched, they only work on android 7.
Could you tell me if it is possible to Downgrade from Android 8.1 to 7 without unlocking the bootloader? All the videos I find, the bootloaders are already unlocked.

As mentioned before - you cannot root a device without unlocking the bootloader!
Why do you want a one click root? They are buggy & full of bloatware
Magisk should be the only method you should be using to root a device - either flashing through twrp or by patching the kernel and flashing the patched image through fastboot
What ever method you choose you need an unlocked bootloader to root!
Why would you want to downgrade? You can flash all parts of a firmware image except gpt & bootloader but again you might need an unlocked bootloader to do this but I don't see the point

In fact, since i need to unlock the bootloader to root, for now, it wouldn't be a good option for me.
But there are apps that I really need and that don't work correctly on Android versions above Nougat, if I could get Downgrade without losing data, that would help me immensely for now.
Is there a possibility that I can downgrade to android 7 with the locked bootloader ? What can go wrong? Brick?

You would have to format data - it would bootloop otherwise and I've already said. Flash all parts of firmware except gpt and bootloader however it may not flash as your bootloader is not unlocked
If the flashing goes wrong and your bootloader is not unlocked you will not be able to recover the device without taking it to a repair shop
My advice just don't bother - if you want to mod your phone unlock the bootloader!
And what app doesn't work above nougat?
