First time LG USER (Apart from Nexus 4) - Bootloader question - G2 General

Hello!
I have a question regarding the bootloader og the LG G2. Maybe this even applies to previous products.
I've owned the HTC one X and if it was a branded phone you could not flash any stock firmware unless you would get S-OFF.
Now what i would like to know is how this is handled by LG? Can anyone enlighten me?
I'm deciding to pick up this phone and i'm not sure about the bootloader but it's of huge concern to me
Thanks in advance

First:
The Q and A section are for questions
Second:
Loki method was just confirmed for the verizon and AT&T version of this device. All you have to do is flash the recovery via adb (or maybe in the future with goomanager) and flash roms (when they are available. currently they are not)
This has a locked bootloader like the One X but Loki is an exploit that goes around the bootloader without having to unlock it.
Third:
htc one x didnt require S off to flash, it just required unlocking the bootloader via HTC DEV after changing your CID (i think that what it is called) to all 1's. S off is security off, it allows you to do more with the bootloader like remove tampered and unlocked or change your CID to another HTC One X variant to get OTAs

My god I had totally forgotten about the Q&A forum. I apologize. Due to my excitement for the LG G2 i just couldn't resist getting this posted ASAP. Much thanks !

New to Evo 3D GSM

Hello,
I got a big sale on HTC Evo 3D (the GSM version). It costed only 300$ without contract.
I owned a lot of Android phones before and i'm not a noob. I was in the testing team for a lot of ROMs.
Since this is my first HTC, can someone explain to me:
- What's HBOOT?
- What's S-ON/S-OFF? Ok, i know it's security ON/OFF, but how does this affect the phone?
- What's the best ROM for the GSM version?
- Why are so few ROMs available?
I installed CWM 5.0.2.0, i rooted my phone and i unlocked my bootloader via htcdev. My HBOOT is 1.49.0018 and my device is S-ON. I have the default firmware (Android 2.3.4, Software number 1.20.401.8).
You were a ROM tester and don't know what hboot or s-on/off is.? Hmmmmmm
From the Best : Galaxy Note
Samsung Galaxy i5500 had an unlocked bootloader.
Motorola Milestone had a locked bootloader, but we could bypass the bootloader via some exploits.
LG Optimus 2x had an unlocked bootloader.
Xperia X10 mini pro had a locked bootloader, but we could unlock it via an exploit made by the great the_laser (the master of Sony Ericsson).
When i said ROM tester, i was saying "TESTER". Install ROM, check the functions, check the stability, check the temperature etc.
Do you get it now? It's the first time i have a contact with the HTC phones.
Don't be rude and be happy when a new guy buys the phone. He will be another person who will install the custom roms on the phone. So, another person who can find bugs.
Wasn't being rude, just wanted clarification. I am glad you're here and always welcome new members. Sorry it came across that way.
Welcome aboard in any case

[Q] T-Mob Update Risky?

I have the m8 rooted unlocked s-off'ed. I have not removed bloatware
or flashed roms. What are scenarios for accepting or not accepting this update.
Thank you any help is appreciated.

This forum is for the M7 variant, but if M8 is similar you will have to put the stock recovery back on the phone. If you unlocked it, then there is the possibility that your data/preload apps are missing and these will have to be replaced because the OTA will check for it. You might check with the HTC One M8 forum, I'm quite sure this is a big topic over there right now.

LG G5 root available for H831 in Canada

Ok, one last desperate kick at the cat. If anyone knows of a root for my G5, speak loudly please! It's a H831, presumably only available in Canada. And for what it's worth, my carrier is Rogers and I'm running Android N 7.0. Solve it, come to town, and I'll buy you beers all night long until the ambulance shows up
Sign the petition to release LG G5 Canadian bootloader
Hi there's a petition to release LG G5 Canadian bootloader on Change.org (Unlock the bootloader for h831, Canadian LG G5) Just sign it and spread the word..
That unlockable bootloader is everything....
It'd be really great if people could do even some cursory searches.
https://forum.xda-developers.com/lg-g5/how-to/info-autos-g5-thread-t3350648
OMFG!! i thought there was a breakthrough!!
stupid title!!
I don't believe this will ever happen
So confused
Ok...... so as we know now... i think (still kind of confused)
There is no bootloader unlock method available for the H831 because even though us canadians give everyone maple syrup and dont start wars,
nobody gives a **** about us..
That being said.... Am I able to unlock the bootloader by flashing a stock rom from a carrier that does allow bootloader to be unlocked, then follow instructions to unlock the bootloader under that stock firmware?
am I missing something?
so to reiterate...
Can I flash my LG-H831 with LG-H850 stock ROM,
then use the method for unlocking bootloader for LG-H850 to get my bootloader unlocked?
I really dont feel like trying to flash TWRP without my bootloader being unlocked because I do NOT have the money to get a new G5 if I brick it...

Sorry buddy, this won't work.
The H831 bootloader is locked, hence it will only run H831 firmware. The moment it sees something different, it will brick.
**** LG
And **** ANY piece of **** corporation that sells ****ing worthless GARBAGE WITH LOCKED ****ING BOOTLOADERS!!!
Extremely near-sighted profit-making scam that negatively affects the entire ****ing world for years if not decades. If you think, wtf do they even gain after the few months that their all-new "apps" and "services" are obsolete??
---------- Post added at 02:47 AM ---------- Previous post was at 02:44 AM ----------
Have a H831 here, mistakenly sold on ebay as a H850 :/
3 years later ! I'd really wish I could do something with this phone, but it looks like it will go to trash
never again i buy a phone from a carrier.
now its unlock from the start or nothing.

Just bootloader unlock won't help for the carrier branded models. Here's why... the T-mobile LG G6 already has bootloader unlock, but LG removed all the other ADB flash commands. So, bootloader unlock is useless on the T-mobile LG G6. Six months later, still no root, no TWRP custom recovery. It's like having the keys to a new car but the car has been melted down to block of metal. The keys are useless.
"BOOTLOADER UNLOCKED" T-MOBILE LG G6

All the fastboot commands have been removed on this device other than lock and unlock. Until there is a method to flash a custom recovery we can't really do anything.

Some more information on the T-mobile LG G6 from an expert:
autoprime said:
T-mobile H872 G6 doesn't have root yet and will only have root once they have a method to get TWRP onto the device. Fastboot boot/flash commands are disabled so it will take an exploit of some sort to get TWRP flashed to the recovery partition.
The only other G6 device that will have root is whatever device LG adds to the official bootloader unlock list which can be found here: http://developer.lge.com/resource/mobile/RetrieveBootloader.dev?categoryId=CTULRS0703
The models added to the bootloader unlock list will be the models to get for proper bootloader unlock, TWRP and root without jumping through hoops like the Tmobile H872 variant does. (currently U.S. and European unlocked carrier LG G6)
For all the other G6 variants without bootloader unlock (AT&T, Verizon, us cellular, canadian, australian, south american, korean, chinese, etc..), a new root method of some sort would be needed but there is nothing public yet. Once a public root arrives and if a debug bootloader image is leaked (like the LG V20) then other G6 variants might be able to have an unlocked bootloader allowing TWRP and permanent root.
Just laying out all the current info to this date. I have no plans to work on any of this as I do not have the device.

Even if you could unlock the bootloader to the other carrier-branded models, LG has probably removed the ADB flash commands from those phones as well? Only the official carrier unlocked versions are eligible for REAL bootloader unlock, the way you are thinking about.
Look down in the development section here for the official carrier unlocked LG G6 (which is eligible for REAL bootloader unlock with ADB flash commands present). TWO pages of ROMs, kernels, custom recovery.
Yet, over on the "bootloader unlocked" T-mobile LG G6 forum, there's 23 pages of root begging thread, which has now been abandoned as a lost cause.
Not only would you have to get bootloader unlock from LG, they would have to add back the ADB flash commands -- or a dev find some exploit to get TWRP custom recovery installed. And that's not been possible yet on the T-mobile LG G6, even though it's bootloader unlocked!
If you are interested in dev stuff for your phone, sell your LG G6, and get one of the official carrier unlocked models -- either the LG G6 or even the new LG V30.

For the carrier-branded models, yeah probably no hope.
My point is LG will say if you are interested in REAL bootloader unlock, they already provide that for the official carrier unlocked models.
Removing the ADB flash commands on the carrier-branded models was very devious "security" method so that cracking the bootloader on carrier models with an exploit (like Dirty Santa) still wouldn't do any good.
With the T-mobile LG G6, devs have has six months to try to find some method of installing TWRP on that unlocked bootloader and not been successful. They may do it some day, but when? Meanwhile the carrier unlocked models have bootloader unlock AND ADB flash commands. If you were a dev, do you go through the already open door or try to break through the brick wall?
Decided to sell my G6 and switch to Samsung after this twitter reply from lg.. this will be last lg phone i bought until they let us unlock bootloader or anyone unofficially unlock..

Why? They said that they don't make the policy of what to unlock.
LG provides two phones that are unlocked and you can develop on.
Most carriers do not want you to have a rooted phone.
Samsung has KNOX which is even worse. If you try to root the phone you can trip KNOX and brick the device.
Samsung does not unlock devices unless you buy a, wait for it, developer version.
HTC is fairly easy if you find someone to S-OFF the device. But that's not HTC.
Mototola will not unlock the bl on branded phones. On other phones it's hit or miss.
LG with their carrier unbranded phones and Google seem to be the most supportive.
If you buy a Pixel from Verizon, the BL is locked and you can't unlock it.

Glad you found a solutions.
IT varies from country to country and sometimes I forget that.
Here in North America (US and Canadian carriers) getting a Samsung unlocked phone just isn't normally possible.
You can't get a version that supports North American LTE with a boot loader you can unlock.
LG and HTC along with Google phones that are unbranded usually can be unlocked here.
Never buying or getting an lg phone ever again...not even for free. Biggest mistake I have ever made...

check the t-mobile threads. there's already someone trying to do just that
Can we start a petition to at least unlock the boot loader for Non carrier branded G6 versions ?
I am losing more and more confidence in LG on supporting our device after their concentration on V series and branding change for G series.
We definitely need software support to our phone to justify all the initial hypes and the money we spent.
Please clear my mind, if someone is officially unlock the bootloader for LG G6 (H870 or US997), then the phone will just lost the warranty. So LG will deny the device.
Than why the other types has not got the possibility to unlock.
If they do so, then we (customers) will have just one way - not to buy phones from them in the future.
Hello,
I just started the petition "LG Electronics: Unlock boot loader for all variants of unlocked LG G6 Smartphone" and wanted to see if you could help by adding your name.
My goal is to reach 100 signatures and I need more support. You can read more and sign the petition here:

Same pinch.
I am coming from LG Google Nexus 5x and I am already suffered a lot for coming out of Nexus line.
I assumed that we can at least Install custom firmware and can be in the bleeding edge.
But LG has prevented that as well.
I would also never buy an LG Phone again.

You need the right file sent by LG because content of the file depends by your IMEI and Device ID. Each unlock.bin file is unique.

Same here. I don't do much dev work or CFW now, but I hate that it's not even possible with this variant. I owned a Google Nexus 6P that started having battery drain issues at just over a year. Nexus Protect will send you another phone for $75, but since they refuse to acknowledge that the battery issue exists, if it starts having issues, they expected me to pay $75 to get another defective one. No thanks.
This phone can't be unlocked, but I suppose I'm just thankful that it doesn't drop to 20% battery in 2 hours and then shut off 10 mins later!

Will a Rootable Android Phone Remain Rootable After Flashing a New ROM

I searched for this question, and couldn't find one detailing exactly what I intend to be asking. I am going to be getting a Samsung S20+ SM-G9860 so that it would be rootable. However, after I get the phone, I intend to flash the AT&T ROM to it so that I may use my carrier specific features. Will the phone remain rootable after doing this?
AFAIK AT&T will not have ROMs with an unlockable bootloader.

So even if the device itself has an unlockable bootloader, the AT&T ROM will not allow it? If so, then that's very unfortunate.

My previous post was erraneous: sorry for this. :crying:
The correct answer is:
Once a device's boot-loader - it's like the BIOS in the PC - got unlocked you're able to root it. Some manufacturers provide a boot-loader unlock tool for certain models of their phones.
If you are able to modify device's boot-loader - means unlock it, then in turn you are able to load whatever Andoid OS you want (clearly and obviously, as long as it works in that device) and root it.
