Having trouble getting to bootloader - LG G6 Questions and Answers

So I got my g6 from sprint and of course they have to throw their customers under the bus and give them a bazillion apps pre-installed on their phones that they can't get rid of. So I've been trying to root my phone because I'm pretty sure a superuser account could let me get rid of all that stuff. I think I'm somewhat familiar with what I need to do, unlock the bootloader, flash a custom rom, yadda yadda yadda. But to unlock the bootloader I need my devices ID to get an unlock key from LG. Problem is I need to be in fastboot to get that info with the application I'm using. Whenever I try to do 'adb reboot fastboot' it just reboots the phone. When I tried to do the thing where you power it on while holding down one of the volume keys it did nothing. I've tried looking around to see if anyone else has this problem or if the U.S. models are't able to access the bootloader menu but I can't find anything. Every tutorial I've watched and read uses the same process but it never works. What am I doing wrong?

Sprint g6 is locked. No way to unlock. In guide sections you can find a thread about debloat without root.

Rooting a flashed NS...noob

Hello everyone, Im new here so please dont kill me if this is a common question. I have searched all over but cant find the answer I need. Im excited to learn from all the wonderful information here and cant wait to get started.
Anyway, I had a Nexus S 4g flashed to work on Boost. I would like to root it so that I can change some things. However, I do not know if my phone was previously rooted. Is there anyway to find out? If it was, and I rooted it again, would that cause problems? Also, does rooting the phone cause problems with the flashing, or will it keep all of the necessary network information intact (so that it doesnt screw up my service)?
Rooting doesn't cause problems with the flashing, it just -potentially- opens up the system to damage. This is a user responsibility and not a fault of the rooting process; it's a possibility of having too much power over the system.
Most likely it would have had the bootloader unlocked and have been rooted. Turn off the phone and turn it on again by holding Vol. Up and Power simultaneously for a few seconds. If it was rooted, the best way to know is if it says "bootloader unlocked" in the upper half of the screen. If not, there is a high chance it isn't CURRENTLY rooted. If it is unlocked, the most work you need to give root access to android is going into recovery and installing a .zip file.
Exactly so after finding that out just look over one of the many guides we have here at XDA to flash the superuser package.
Sent from my Nexus S
I didnt see anything saying unlocked. I see 'Lock State - Locked', so Im assuming this means that it is not currently rooted. I guess now I will go through some guides and learn which method would be best for me. Thanks for the quick reply and help.
Most likely you aren't rooted either - you can test by typing "su" in terminal emulator.
Just remember if u unlock bootloader the internal data and sdcard will all be deleted.

Need som clarification on bootloaders..

As I'm writing this, the vBulletin search is down, so I'm unable to see if others have already asked.
Okay, rumors say, that LG will soon allow unlocking of bootloaders on many on some of their flagship devices.
But this left me wondering, what will the advantages of that be over what we have now? I mean, we can install custom recovery, custom roms, and all that. Sure, we might not have to look at the LG logo every time the phone boots, and we wont get the "press power button to enter recovery" screen, but I dont care much for that. So to sum it up, what are the advantages for he G2 to an Unlocked bootloader?

Advantages, More acces, No need to lokify that's the biggest advantages :/
I also had the same question. I read that the bootloader was locked, and then was relieved seeing there were quite a few custom AOSP roms. It flashed just fine and it worked for me. So, how did the bootloader affect me? In no way at all, but apparently it's thanks to a specific hack called loki which is a workaround for the bootloader. This means that you can't know for certain if it works for all users or when it will get patched/stopped working, or even bring more problems into the phone. At the moment there's some problems in making both AOSP and stock roms working in a dual-boot way and apparently it's due to the kernel which gets loaded.
The dependence on the hack means that at any point LG might release an update to break it. Although that doesn't seem to be the case as we have received an email from LG saying they might consider unlocking the bootloader after all (see p880).

Root Help, I need some advanced thinkers.

For work I have to use mobileiron, which detects everything from root to the unlocked bootloader. I am not sure if it simply detects the unlocked bootloader or detects because of the warning that comes up, I would guess its the latter.
So not only can't I root, I can't unlock my bootloader in the current state. At the very least I would like to enable wifi tether, and I would do that through TWRP but then I can't unlock my bootloader. So way to relock without wiping.
So I guess the question is for people who don't know about MobileIron is will we be able to unlock the bootloader without setting off any other options? or is there way to at least edit build.prop without root or unlocked bootloader?
I guess ideally if I could root without unlocking the bootloader then unroot that would solve my problems. Thoughts anyone?
Here is a thought, although it might fail. You could unlock your bootloader, boot TWRP without flashing(fastboot boot twrp-rgvrg.img), make your changes, then boot back into the bootloader and relock it.
Still can't say for sure it would work and it will virtually guarantee your userdata be wiped.
Buy a second phone for work related purposes
I'd never spend so much on a phone just to let my company lock it down
You could always test out various configs and see what trips the software or not. You might be able to keep TWRP and root just turned off via supersu and everything work. Similar to android pay. You might not even be able to unlock the bootloader. Anything in between in possible.
Regardless it is pretty trivial to go back to stock and get everything locked back up again. So there is little risk in trying.
If it were me I'd try root and see if it worked. No? Ok, try to disable root with supersu. Will work or not. If not then make your host file edits for adaway and such and then completely remove root. See if that works.
You can also try to unlock the bootloader now as stock and see if it impacts the software. See exactly where it trips and prevents you from using it. Then work from there.
If nothing works, go back to 100% stock and lock the bootloader again. At least you gave it a go and had some fun for the evening. If I had to guess something in between will work and you can work around the limitations.

Have an unlocked bootloader - how to re-lock? Google Pay fails because of it?

I bought a used Essential (love it!). It came with the bootloader unlocked, so every reboot I get the "your device software can't be checked for corruption. Please lock the bootloader."
I am not really concerned about that (should I be?), but when I try to set up Google Pay I get this:
"Couldn't finish setup to pay in stores. This phone can't be used to pay in stores. This may be because it is rooted or altered in some other way."
I'm not sure that the Pay issue is because of the unlocked bootloader, but I don't need it rooted/unlocked, so I might as well re-lock to eliminate it as an issue.
There's a lot of info on the forums about *not* relocking when you have a custom rom, but I'm pure Pie.
So - is there a straightforward way to relock? I have things backed up/etc.
back to official rom, before that
First of all make sure you are pure stock
Then boot into fastboot by holding vol- and power button together.
Download android platform tools https:REMOVEME//developer.android.com/studio/releases/platform-tools?hl=th, unzip it, go into the folder, open cmd there, and type
Code:
fastboot flashing lock
And it's finished!

Look at the other threads about rooting.
You can do a couple of things to solve the issue:
Install ElementalX kernel
Install Magisk

Perfect! Flashed the latest original from Essential per HapRow's comment, pulling from Essentials current build website.
Had to wait a long time to restore everything. Then the "fastboot flashing lock" erases everything, so I had to restore again.
Took a while, but was thankfully uneventful.
And now Google Pay works!
Thank!

oneplus 8 pro crashdump/fastboot brick, again

i know there are a ton of discussions on this but it seems that every thread just dies off and nothing in depth gets discussed. oneplus is useless in this, and it also figures that the phone would wait for me to pay it off before it self bricks for no reason.
i know im gonna have to wipe it at some point, but i REALLY need to get some data off of it. the bootloader claims its locked when i know i unlocked it forever ago, and nothing that fastboot offers is doing anything for me. i cant use oem unlock, i cant flash anything to it, and unlike earlier today, multiple reboots no longer bring it back to life.
so, is there a way i can force this paperweight to take a dirty software load? or can i get fastboot to dump all my data into a folder or something? i havent been around really since the CM days, and Im very sure I simply cannot search for the right terms in the right places.
ive also made posts in the xda and oneplus discords with little reply (it is late in the US so im not overly surprised about that at all.
as an update, it booted into recovery this morning, i backed everything, unlocked the bootloader, and got about 5 hours out of it.
after getting fastboot to finish the oem unlock, i tried flashing twrp recovery which did nothing, flashed carbon, which did nothing, used the MSMdownload tool, which has done nothing but relock the bootloader again. im at a huge loss here.
is this motherboard level?
Alright mate. Sounds like you're having a mare.
Personally I haven't had a single bootloop besides, OnePlus do provide tools that a lot of companies don't, like MSM, so be grateful for that. Plus it's super easy to unlock and relock the bootloader, also OnePlus will allow you to retain warranty even if it has been unlocked.
So go easy on OnePlus. Believe me it could be worse, naming no names.........
Samsung. LG, Motorola, Sony, apple.
As for your issue, when and how did it bootloop, it is quite rare for a phone to simply behave that way on its own
Are you / were you rooted?
Did you confirm that the bootloader was unlocked? If you're rooted then I think that confirms that you did.
The only way I know of to relock the bootloader is the fastboot command to relock and or the MSM tool.
So can you fill in the gaps as to how you managed to get there??
Finally, if you are indeed bootloader locked and unable to get into your device then yep you're screwed, however you could wipe system from recovery, this will nuke your apps, but your storage will remain intact .
So if that suits your needs then go for it.
Let me know about the bootloader before you commit
