The issues with getting root and idea to change it? - LG V30 Questions & Answers

Hello everyone, I have found that every since the LG G3 development for most LG devices that are from carries are usually neglected development wise. I have been on websites from other places like smart things where people share their code and it isn't about the money, it's about having fun doing things you are not supposed to with the device. I had the Verizon LG V10 and I never got Jack S***t for development sadly, I tried my best with a few people to try and develop root, but our knowledge wasn't great enough. So my idea is this. what if we as the v30 community used all our knowledge to take root? we find an exploit and put our time in to make it. This is just an idea and am wondering if somebody has good code knowledge and would want to do a community made root. I hope to hear some comments on thoughts. thank you guys.

Development has slowed to a crawl because LG has made it next to impossible to root their phones. The only reason that the V20 has root for all models is because an unlocked engineering aboot leaked.
I have done several write-ups on how protected boot works in the V20 forums ... you should check them out.
The bottom line is there just aren't any attack vectors. Quallcomm took Google's reference implementation, and took it even further.
Let's say that a kernel exploit was found for the V30. Without the ability to unlock aboot, you are still stuck since aboot verifies the integrity of boot and system.
Attack trustzone used to be a possibility, but with the PBL verifying the integrity of EVERY piece of the SBL, you would need a piece of hardware between the CPU and the NAND to do a MITM attack, and that is just way outside the scope of your average Android hobbyist.
The V20 will be my last LG phone due to their security.

This has all been discussed thoroughly since early September (even before release of the LG V30) in this thread:
LG V30: Unlock bootloader and Root
That thread currently has 30 pages. I'm just pointing out you are starting a duplicate thread to discuss the same thing...
On the first page of that thread, in post #7 (September 3) and post #9 (September 4), I posted in depth reasons (based on the 2017 LG G6) why there would probably be no dev work on the carrier-branded LG V30 models, and why no one should buy carrier variants if they cared about root, ROMs, TWRP, kernels. And I gave recommendation of exactly what to buy ("open market" North America US998 and Europe H930) if you cared about XDA dev work. September 3 and 4 was WEEKS before even the South Korean models were released, and over a month before the U.S. carrier models were released. My point is everyone who researched knew beforehand what to expect.
And in that thread, after the U.S. carrier models were released, people confirmed exactly what we said back in early September. Almost all the carrier-branded models have locked down bootloaders, and while the T-mobile H932 bootloader can be unlocked it really does no good. (If you don't know why, keep reading.)
Someone else later started a T-mobile LG V30 H932-specific root thread, based on the idea that the T-mobile variant at least starts with the advantage of having easily "unlocked" bootloader. (Skip the first few posts, as the OP initially didn't specify he wished to ONLY discuss the T-mobile variant; he later clarified that.)
Of course, we all know that having "bootloader unlock" does no good with the 2017 LG flagship carrier-branded models, since even 7 months after released the 2017 "bootloader unlocked" T-mobile LG G6 still doesn't have root or recovery (23 page root pledge thread abandoned as a lost cause).
Yet, there's two pages of XDA development on the "open market" LG G6 models (North America US997 and Europe H870.
WHY? Because starting with the 2017 LG G6, LG has removed almost all the ADB fastboot commands on the carrier-branded flagship models -- so that even if you unlock the bootloader (on the other carrier branded models) with an exploit similar to "Dirty Santa", then you probably still can't do anything. You either need root first to get recovery or you need recovery first to get root. Can't have one without the other. So, even if this LG V30 T-mobile H932 group DOES get root/recovery on the T-mobile H932, then what? Well, yes the T-mobile H932 gets dev work -- but then you would still need to crack the bootloader of all the OTHER carrier-branded models to implement that method.
I wish them luck, but we know the hurdles the face. But you are welcome to go discuss ideas there. There's 5 pages of discussion in that thread.
T-mobile LG V30 H932: Progress Towards Root/TWRP/ROMs (not achieved yet)
So, there's two threads already going about this topic. Anything you wish to discuss can probably be addressed in either of those two threads.

Which is why the "open market" LG phones that are placed on the LG Developer Bootloader Unlock List is really the only guaranteed option. You get bootloader unlock with full ADB flash commands.

Note the "open market" LG V20 is clearly on that list. These models do NOT require any exploits or attack vectors.
In the past, if you found bootloader unlock exploit like "Dirty Santa" -- BOOM -- you could then get root and TWRP recovery even on the carrier branded models because the ADB commands were there. Now, starting in 2017, it seems the ADB flash commands are only present on the "open market" models.
But, there's plenty of XDA development on the "open market" LG G6 models (North America US997 and Europe H870, and there will be even more for the "open market" LG V30 models, once they are placed on the LG Developer Bootloader Unlock list. (Took six weeks after release for the LG G6 US997. Released May 12 and placed on LG Developer Bootloader Unlock List on June 30). That's why I'm waiting for the LG V30 US998.
These North America US998 and the Europe H930 are GUARANTEED to have dev work.

The G6 is considerably newer than the V20, and as long as you bought the correct G6, is easily rootable. Only the H870 International variant and the US997 could be rooted, due to the unlockable bootloader and the ADB commands.
But then it should be easy - register with LG for the unlock, use the tool to flash TWRP, install SuperSU or Magisk and you're done.
You just have to do a bit of research, and have a lot of patience because the dev models come out later than the carrier models, before buying.

I am well aware that the unlocked models that you buy from LG have full fastboot. What the unlocked V30 doesn't have is the 600Mhz band.
I use TMobile, and I am not about to buy a phone that doesn't have that band.

Since the phone's not been released yet we don't know that for sure. LG could file an FCC amendment for the "open market" US998 or perhaps that band can be enabled with root (if hardware permits) by flashing the T-mobile radio over it.
No other phones, T-Mobile or otherwise have that band 71 either right now. So what will you buy instead if you want root?
You going to wait for the 2018 "open market" LG G7 -- which will probably have that band already enabled? Because the 2018 T-mobile G7 variant will be locked down, as will the 2018 T-mobile Samsung Galaxy S9/S9+.

You are 100% correct, they could file an amendment, but I am not holding my breath.
I don't *need* a new phone right now, but the V20 was getting a little long in the tooth, so it would be nice to upgrade
I am just going to wait for the next refresh cycle to see if there is a phone that meets my requirements a little better, but it will definitely be either an unlocked LG, or a phone from a more developer friendly manufacturer -- like OnePlus, or Razer.

quick question is there a way you can see list of available commands like how sometimes you type help or w/e it may be over adb to see which ones are avail is it possible they just renamed commands that you would use to flash

Yes, I can see all the list of commands available on my phone -- but my phone is the open market US998 V30, which is bootloader unlocked and rooted.
However, I believe someone else did the same for the T-mobile H932. I remember one available command surprised them, flash all? I would have to go back to the thread to confirm my memory.
Found it in the general Bootloader Unlock and Root thread, from October (now up to 50 pages). This person is the one who then started the H932 specific thread (which is up to 94 pages).

Looking through the fastboot command and I mean command because there is one I think I may have a way to root possibly. we have fastboot flash all still, if we modify a ota zip to flash via fastboot and modify the boot.img we maybe be able to get magisk.

When you're in the bootloader, you have to use fastboot commands. This lets you see all the available fastboot commands...
fastboot help
Apparently on the H932, only "flashall" shows up when using the help query.

not so sure how to post pictured but i put a link there of the commands avail.. Anyways i have a question if anyone knows if i take the stock roam and load it into the emulator im not sure if thats possible, can you root the rom then save it and load it onto your phone or will it not take .?

For the T-mobile I don't think all those commands are actually available, even though they are listed in "help". I know T-mobile users have tried to run some of those commands and were unable to. So, I guess "help" is not the resource to use, then.

They stripped the commands on the T-Mobile H932, but apparently left them in the help file.
Member @crazyut posted here (in the T-Mobile H932 root thread) the outcome when he tried to run fastboot boot on his carrier unlocked US998. His phone should have the full list of fastboot commands (assuming it is the open market US998) so it stands to reason that it would accept fastboot boot -- as apparently it did. He received a security error, either because it was still bootloader locked at the time (which would prevent fastboot boot from working altogether) or because the image he tried to boot didn't pass dm-verity or RSA checks.
I have not seen reports from anyone actually trying fastboot boot on the H932, but I am sure some must have tried it. Based on input from @runningnak3d and others with deep LG experience and insight, it was stripped from the T-Mobile models along with the fastboot flash commands.
I highly recommend the H932 root thread, as much terrain has already been covered. For those without time or patience, you could start here (page 70).
Personally I should stop following these root threads: My fingers are itching to experiment on my own TMO V30+ but I simply cannot risk busting my warranty. In our household we only buy new phones every 3+ years, and we were only able to afford V30s thanks to TMO's BOGO and LG's $400 rebate. I don't strictly need root anymore, my interest is mostly custom ROMs for when LG/T-Mobile stops updating us.

When you type fastboot help, the output comes from the fastboot command that you have installed. There is no command to query the phone to determine what commands are available. Prior to the SD835 you could decompile aboot to figure out which commands were actually available. With the SD835 the apps bootloader is now called abl and is encrypted. Thank you Quallcomm for a completely useless piece of "security".

Oh, I see. So the help text is completely separate from the phone. Duh...
Thank you for that explanation.

In terms of software mods (ROMs, etc.) are the V30 and v30+ for Sprint identical?

Question in topic. I'd like to get the V30+ if there aren't any differences as so far I'm not finding any modification discussions on the V30+.

There's no functional differences (software) between any of the V30 and V30+, except for extra 64GB internal memory (which is hardware). Some carriers are offering free premium earbuds in the V30+ box, but that's nothing to do with the phones themselves.
As for mods, unless you mean simple debloating there's nothing you can can do to "mod" without bootloader unlock and root.
No carrier branded versions will qualify for LG's bootloader unlock list and root. Only the North American and European carrier unlocked versions ("open market" versions) will get guaranteed bootloader unlock and root.
* European H930 was released in early November.
* North America US998 will be released in early December. (THAT is the official carrier unlocked V30 version, NOT the U.S. Cellular carrier-branded model. Carrier-branded versions will not be eligible for LG Bootloader Unlock List.)
Neither of these models have yet been added to the LG Developer Bootloader Unlock list, but should be in the coming weeks. Took six weeks for the LG G6 carrier unlocked models to be added to the bootloader unlock list. When they are you'll start seeing Development threads.
So far, none of the official carrier unlocked versions are V30+. EDIT: The LG V30 H930G (which is V30+) was added to the bootloader unlock list today.

I haven't had a LG phone since the LG G3 and was wondering how unlocking the bootloader would potentially affect the warranty. With the G3, it was unofficial for my device and wasn't traceable if I had to send it in for warranty claims / service as long as I did a hard factory reset. Prior to owning the G3 I owned exclusively HTC devices that had the bootloader modified check showing "S-Off" or "S-On" depending on whether the bootloader is or was tampered with. Thankfully there were simple exploits to restore this prior to sending it in for service. I know Samsung's KNOX is also a pain in the ass. I guess my question is since I will purchase the US unlocked model regardless, will there be any way of protecting my warranty if I unlock the bootloader? For example, could the official unlock software be reverse engineered to create an unofficial unlock method that would circumvent tripping these potential flags? Or could an exploit be found after the fact to erase signs that the bootloader has been previously unlocked &/ or tampered with?
*Edit*
I probably should have started a thread about this...

Feel free to start a thread but do NOT do it in this Q&A format. Start a REAL thread. You have to use a web browser to answer these Q&A format questions and you can't easily quote, etc.
Unlocking the bootloader will void your warranty if you do it officially through LG. LG3 was a long time ago in software years. It's harder to crack bootloaders and LG removed most of the ADB flash commands even if you do so. Only the "open market" versions have LG sanctioned bootloader unlock and full ADB flash commands.
See posts #6, #7, #9 of this thread, which was written back in early September. Yes, it seems to discuss T-mobile a lot, but that's only because T-mobile bootloader is easily unlocked. Still doesn't do any good. The answer is REALLY for all carrier-branded models.

No Fastboot?

Hello, I have a Sprint lg v30 plus. I'm new to lg devices. Whenever I try to boot into fastboot mode the device just reboots. I tried using adb and reboot bootloader from recovery. I know the device probably locked but lg also removed fastboot? I can get to download mode and recovery. Any ideas?
Seems the Sprint model is locked down... Was hoping it was like the T-Mobile model so I could at least unlock the bootloader
EDIT: Since this thread was dug up, all V30 now have bootloader unlock with TWRP and root possible

No all carrier models have locked bootloader except T-Mobile. And for the T-Mobile variant, they removed most of the fastboot flash commands.
Only the open market variants have (or will have) unlocked bootloader and fastboot flash commands.
Over in the T-Mobile thread, they're very close to finding a workaround to get root.

I have an LG-H931 (US AT&T). I cannot reach the fastboot mode in any way. adb reboot bootloader does a regular reboot instead of into the fastboot mode. Power off, hold volume down, plug in USB cable, it boots normally. Power off, press and hold power+vol. down keys, release when logo appears, boots normally. I tried adb reboot recovery. It loaded into recovery, but no options of any kind were available. It's as if fastboot does not exist.

What's the point anyway? H931 will never get bootloader unlocked so fastboot is useless for you even if you could boot into it.

You replying to a thread back in February 2018. Try looking at current threads where we discuss all this stuff.
You have to Frankenstein to US998 to get fastboot flash commands to unlock the bootloader for Sprint LS998, Verizon VS996, AT&T H931, Canada H933, "regional" AS998.
If you have Sprint LS998 and want to use Sprint, you need to activate your phone first before doing any of this.
After Frankenstein to US998 you can bootloader unlock root, install TWRP, root. And you can still use the phone on Sprint by flashing back the Sprint modems.
If you are not using Sprint, and don't care, then don't worry about flashing back Sprint modems. I converted two LS998 V30+ to US998 and use them on AT&T.

Hi ChazzMatt,
Thanks for your reply and direction. After I posted last night I did some deeper reading into both the Frankenstein
and WTF threads. I figured I needed to flash the different ROM before creating access to the bootloader. I thought I could circumvent the flashing process and access my Sprint bootloader. I now realize the Sprint version does not have access to it.
Regarding the last post being in February, no one ever closed out the question. People forget all the time to follow up with what they found. I googled "no bootloader V30" and came up with this thread. Now anyone else who finds this will know where to go. Thanks for your help.

Well, back in January/February 2018 we weren't aware of Frankenstein here on XDA (converting to another variant, like US998) -- but online unlockers were doing that with dedicated "Octopus" boxes.

}
And even when we did become aware of Frankenstein (whether by Octopus box or dev patched LGUP), you still couldn't unlock the bootloader by yourself. You needed an OFFICIAL device-specific bootloader unlock code from LG, and those were only distributed to certain models (open market US998 V30, open market H930 V30, and H930G V30+). LS998 is NOT eligible for that "official" bootloader unlock code, even when converted to US998. You had to register with LG website and provided proof your phone was eligible with purchase receipts and not only IMEI but DEVICE-ID.
Simple OEM bootloader unlock in Dev Options (since Lollipop) doesn't do anything unless the carrier/OEM wants it to do something.
So, at first the Frankenstein method (thread created in late April 2018) -- which used dev patched LGUP and replicated an Octopus box -- was mostly used to either SIM card unlock Sprint LS998/AT&T H931 to carrier unlocked US998/H933/AS998 OR sometimes convert the "cheaper" LS998 to more expensive Verizon VS996. Nothing more than that.
At that point in time, with Frankenstein you still could NOT bootloader unlock an LS998, even when converted to US998. You could only convert to one of the carrier unlocked variants to SIM card unlock the LS998.
THEN, in mid-May 2018, EVERYTHING changed. @TxanMoe discovered the WTF LG Oreo bootloader unlock exploit which allows all variants with fastboot flash commands to use a "fake" bootloader unlock code. So, Frankenstein + WTF bootloader unlock exploit allows ALL V30 (except T-mobile H932) to have bootloader unlock and root. H932 only recently joined the V30 root party (mid September 2018) through another method developed by @runningnak3d.
See this quote below? I'm only using it to point out the danger in resurrecting "old" threads.

What's the point anyway? H931 will never get bootloader unlocked so fastboot is useless for you even if you could boot into it.

Sounds hopeless, right?
Yet, @padmanek is the person who then gave us dev patched LGUP, which is critical to Frankenstein and WTF bootloader unlock and root. Yes, used on the H931 which now has bootloader unlock. Every place I post dev patched LGUP, I give him credit. I myself said many things months ago that are now totally wrong, with new information and developments.
@JWnSC;75213369, who started this entire thread, later created a thread devoted to HOW to bootloader unlock and root the LS998:
January 2018
JWnSC said:
Hello, I have a Sprint lg v30 plus. I'm new to lg devices. Whenever I try to boot into fastboot mode the device just reboots. I tried using adb and reboot bootloader from recovery. I know the device probably locked but lg also removed fastboot? I can get to download mode and recovery. Any ideas?
Seems the Sprint model is locked down... Was hoping it was like the T-Mobile model so I could at least unlock the bootloader

US998 to LS998 *Sprint LTE + Root*

Is the LGUS998 Official Bootloader Unlock No longer available?

I bought a carrier unlocked LG-US998 phone on ebay and attempted to unlock the bootloader. I followed the instructions which have you go to the official LG bootloader unlock, fill in imei and device id, inspect element, and replace the LGUS997 text with LGUS998, but it won't work.

No, you are quite fine and can unlock your bootloader in just a few minutes. See point #2, but first I'll explain your issue with the LG Developer Bootloader Unlock website...
1) Off eBay, did you buy an open market LG US998 V30 (originally sold through 3rd party retailer like B&H Photo) or just a U.S. Cellular model US998 V30? Or US998 sold by other regional carriers? They are the SAME model and BOTH are "carrier unlocked." Unless you buy it new, you can't know. Unless the seller includes the purchase receipt.
The difference is the B&H Photo and other authorized retailers sell the OFFICIAL "open market" LG US998 V30 -- and those have IMEI and DEVICE-ID registered on the LG Developer Bootloader Unlock list website to be eligible for bootloader unlock code.
U.S. Cellular model US998 and other carrier-sold models are not eligible for LG bootloader unlock code.
2) None of this LG Developer website stuff is necessary at this point in time.
Every LG V30/V30+/V30S on the planet -- except for the T-Mobile H932 -- can be bootloader unlocked and rooted, thanks to a wonderful bootloader unlock exploit @TxanMoe discovered in Oreo. We don't need LG permission and unlock code any more.
See the WTF bootloader unlock and root thread. Since you already have US998 is going to be very easy for you. You already have fastboot flash commands, whereas other models like LS998 have to first go through Frankenstein method to get fastboot flash commands.
US998, H930, H930DS, V30S are the easiest.

I guess it must not have been a true open market version. I saw the method you mentioned in the thread, but it looked sketchy, so I wanted to make sure I couldn't do it the original way first. However, I tried the WTF Bootloader unlock and it worked! Thanks for taking the time to explain the different phone versions and linking to the thread. I now have an unlocked bootloader!

You're welcome!
I have three official open market LG US998 V30/V30+. I also have two LS998 V30+. Five, total. Most are bootloader unlocked, but I only used the LG Developer Bootloader Unlock list website (and LG code) for the very first one. The others used the WTF bootloader unlock exploit. MUCH easier!
For the LS998 V30+, of course I had to Frankenstein convert them to US998 V30+ to get fastboot flash commands.
Point is, I've done it both ways -- as well as starting with US998 or having to convert to US998...
I also wrote the guide for the WTF bootloader unlock and root method.
US998 stuck in fastboot mode
The WTF method isn't working for me, I also need to see if anyone has a fix/ soluttion for US998 stuck in fastboot mode

Strange then you didn't post in the WTF thread, instead of this totally irrelevant thread from July 2018. Why did you dig up this OLD thread and post something not even related here?
If WTF isn't "working" for you then it's because you aren't following the instructions. I also bet any problems you are having has questions and answers IN THAT thread. Not this one.
For instance, OH LOOK:
https://forum.xda-developers.com/showpost.php?p=79359056&postcount=2854
Please continue any discussion in the WTF thread and not this thread you hijacked.
Please enlighten me then.
If you're so positive it works and you feel that I'm not following the directions properly please enlighten me on how I should do this because I've tried numerous times and now I'm stuck in fastboot mode and cannot get out of it I can't even access the download mode The flash the firmware using LG up patched. Also I would appreciate the sarcasm to tone down, it's unnecessary and quite frankly I'm simply just asking a question there's no need for a snippy response.

Why don't you go to the right thread first.
Why don't you see the link I posted for your solution.
Snippy response is for digging up and ruining this thread. You posted in totally irrelevant thread for no reason whatsoever, and when I pointed that out and gave you a solution, you pretended you didn't see the solution and posted in the wrong thread again.
"LG Official Bootloader Unlock" (this thread) has NOTHING to do with your problem.
Go back to WTF thread which is what your issue is about. See the solution I posted above and there are probably more in the WTF thread.

And your first response was to POST in this thread that has nothing to to with your problem, instead of asking for help in WTF thread? Has nothing to do with being tech savvy, but has to do with forum etiquette. This thread has outdated answers (H932 is NOW rooted, but wasn't back in July 2018).
The first thing you should have done is post in WTF thread.

US998, Unlocked or US Cellular?

Hi guys, I am looking for a concrete way to tell. I called us cellular they said "I am %110 sure it is not a us cellular phone" and the current patch on the phone is us99820a.
Is there a guaranteed way? Something I can see and then be guaranteed it's the unlocked version?
And no it does not have the B&H logo.

Not sure why you are asking. All US998 are SIM card unlocked/carrier unlocked. Even those Frankenstein converted from Sprint LS998 and being sold on eBay as "US998". As well as those US998 sold by U.S. Cellular. All US998/US998U are carrier unlocked (from release date in 2017) and can be bootloader unlocked and rooted (since May 2018).
The only difference is the official "open market" US998 V30 (64GB) phones (like those sold by B&H Photo) have their IMEI numbers and DEVICE-ID registered on the LG bootloader unlock website, which make them eligible for now irrelevant LG official bootloader unlock code.
HOWEVER, even "open market " 128GB US998U V30+ are NOT eligible for official bootloader unlock -- only the 64GB V30 US998 -- and LG won't explain why. So, there's NO difference in any of the 128GB US998U V30+ for U.S. Cellular, B&H Photo or some other North American variant "Frankenstein" converted to "US998" V30+.
GUESS WHAT? NONE of that matters anymore. We have bootloader unlock and root for ALL V30/V30+/V30S thanks to XDA, and don't need LG's permission.

No phones sold by B&H Photo in New York have a "B&H" logo on the phone. Why would they? I bought three US998/US998U from B&H Photo. B&H Photo is a company in New York city that sells electronics. They are one of the "open market" LG authorized 3rd party retailers, along with Best Buy and Amazon.
You are obviously confusing B&H Photo with B&O? B&O is a global sound design/manufacturing company that has partnered with LG on several occasions. But no North America LG phones will have B&O logos because OTHER companies have rights to that logo in U.S. and Canada.

If they are asking, they are asking out of ignorance and you need to educate them. It doesn't matter what kind of US998 it is, it can be bootloader unlocked and rooted and it's already carrier unlocked.
All US998 are SIM card unlocked/carrier unlocked. You will see some eBay sellers saying U.S. Cellular US998 are locked to U.S. Cellular but that is not correct. That is generic language that may apply to OTHER U.S. Cellular phones, not the V30/V30+.
If have a US998 V30+ you bought off eBay from a dealer like yywireless, it probably previously was a Sprint LS998 V30+ and was Frankenstein converted to US998 V30+. Doesn't matter. Tell them it's a SIM card unlocked US998 that can be easily bootloader unlocked and rooted. Point them to this thread below:

All security updates are posted here in XDA as soon as they are released. He can easily manually install them when he wishes instead of the partial image OTA being forced on him.
20E is the latest update for US998, released in September. You can update to that very easily if you wish. Just use "upgrade" in LGUP app. All data is saved, all apps saved. Takes 5 minutes.
The only thing is you NEED Oreo 20A or 20B to bootloader unlock, THEN you can update to the newest. Unless you or the buyer doesn't wish to unlock bootloader and root.
When you are selling the phone, STRESS THAT IT'S ON Oreo FIRMWARE THAT CAN BE EASILY ROOTED. 20A is a SELLING advantage! If you update to newest firmware, they will have to downgrade anyway (temporarily) to unlock bootloader.

Thank you so much. If I can bother you one more time, Is there a way to tell if Frankenstein has been used and how to tell the bootloader is unlocked. I asked before I bought the phone and the seller said no to both. (I bought it two months ago).

If the bootloader is unlocked 99% of the time, when turning on/rebooting the phone you will see a VERY annoying -- even scary -- bootloader unlock warning. It's just a "picture" LG throws in your face.
For the US998, there is an obscure way to hide that, but most people don't bother or don't know how. I don't bother. If you do not see this message, your bootloader is probably not unlocked.
Yes, there's an ADB/fastboot command you can run that will also tell you for sure: fastboot getvar all
This is how @TxanMoe PROVED his WTF bootloader unlock method worked for LG V30 Oreo.
But if the seller says it wasn't unlocked, then it's probably not unlocked especially if you don't see that warning message when you turn on the phone...
How to tell if it's been Frankensteined to US998? The IMEI will correlate to another North American variant's (LS998/VS996/AS998/H931/H933) database of numbers -- but that's beyond my knowledge as to what those numbers would be.
There are IMEI online database search engines that claim to tell you that:
https://imei24.com/imei_check/LG/
Like that one above and there are others.
When me and my friends/relatives stick in our AT&T SIM cards, the phones work with fast LTE so I don't care. My wife is currently using an LS998 V30+ I converted to US998 V30+, on AT&T. Her bootloader is unlocked but she's not rooted. I may do that at some point in the future when I have more time.

Do I plug in my phone, open cmd, and just type fastboot getvar all?
Or do I need to plug it in, shift+right click adb folder, start adb, and then do it?

Thank you for all the info. The only reason I thought the bootloader might be unlocked is when I start the phone into fastboot mode, it says:
Check if bootloader is unlocked
Fastboot getvar unlocked

Do it the same you you have done previously to start the phone in fastboot mode.
I assume you must have turned on Developer Options in the past, turned on USB debugging, allowed authorization for your PC. You said you were in fastboot mode before... You're now just typing a command that will give you information about the phone.
See screenshot on previous page for @TxanMoe.
If you want to make sure that your phone is connected:
adb devices
Which will simply list android device connected to computer (devices with usb debugging turned ON). This isn’t really necessary as it’s a part of the commands used later on, but sometimes it’s a useful way to make sure all things are GO.
First we need to reboot phone into bootloader mode
This you can either do manually, or with ADB and Fastboot installed on computer. You have a simple way HERE how, or use the more complex android sdk way. Simply use a ADB command for it.
adb reboot bootloader
This will force the phone to reboot into bootloader, if everything works like it’s supposed to, you will see windows load the fastboot driver.
Now you enter the fastboot main command with the command getvar (get variable) and “all” as parament for that
fastboot getvar all
Which will get you a list of various variables on the phone.

Thank you a million times over. I have confirmed it is indeed locked "(bootloader) unlocked:no". I appreciate all your help and patience with me today

How to tell if it's been Frankensteined to US998? The IMEI will correlate to another North American variant's (LS998/VS996/AS998/H931/H933) database of numbers -- but that's beyond my knowledge as to what those numbers would be.
There are IMEI online database search engines that claim to tell you that:

Thanks to that page I confirmed a slight suspicion I had about the phone I bought as a US998U - it was originally an LS998U. The reason I was suspicious is Verizon's website won't accept the IMEI to do an official swap from my Droid Turbo - I just put the SIM from the Turbo into the V30 and it's mostly working. The other time I had that problem I was doing an IMEI swap to move a Nexus 6 from Sprint to Verizon.
I say my V30 is mostly working because I've been having signal issues with it recently - I didn't seem to have as much trouble when I first got it. I'm looking at nuking it and reinstalling US998 firmware from scratch to eliminate that a possible cause.
EDIT - when there was the Magisk bootloop problem, I did some things to fix it before I knew it was the source of the trouble. I was doing some other firmware experiments that I thought caused it, and may have made things flaky.

Sure, reinstall US998 firmware but also be sure to flash Verizon modems if you want to test signal differences. Some people like the US998 modem on Verizon, while others like the Verizon modem on Verizon.
For Verizon, for most/all of these Frankensteined phones, you will need an already-activated Verizon SIM card. They don't understand that the IMEI does NOT equal the current version of phone. It's no longer a Sprint phone (or whatever), it's now a carrier unlocked US998 -- no matter what the IMEI says.
Someone else had some similar problem with AT&T, trying to bring over a Frankensteined phone to officially "register" it. No, just stick in an already activated AT&T SIM card! Maybe they didn't have one. AT&T accepted my true US998U V30+ to register it, but for my wife (she's used both true US998 and Frankenstein LS998 V30+ converted to US998U), I didn't even bother going to AT&T store. I just stuck in her Moto Quark SIM card card.
When I moved my mother over from Tracfone LG "feature phone" to my AT&T account this last summer, luckily I had a spare "true" US998 V30 to register her. I didn't have an already-activated AT&T SIM card for her phone. They just scanned the bar code on the box and it was good to go.
The Verizon modems were what I was fooling with the same day Magisk 17.0 was released - this is why I didn't realize that was the actual cause. I don't know if I corrupted something or not trying to fix the bootloop before knowing the cause was updating Magisk without uninstalling, so I'm going to start clean with full wipe and fresh flash of US998 20e firmware and Verizon modem.
As I said the SIM I'm using is was already in use with Verizon from my Turbo and the phone works - I've been using it for about six weeks. The IMEI swap on Verizon's side is because of insurance coverage - since I have to deal with a rep (since the website won't accept it) it has very low priority.

Hi bro, thanks for your usefull info.
But to make it more clear to myself, so US998 V30+ is basically already unlocked right?
No need any Factory Unlock like t-mobile version to use other carrier, even I'm doing flash/update or even softbrick bootlop which ended to flash stock rom and it will not locked.
Mean is I can use it to my country (Indonesia) which have band support LTE 900(8) this band doesnt exist in US988, but the other one 3(1800) can be used on Telkomsel carrier.
Why I'm buying this over H930DS officially distributed in Indonesia?
Because US998 can be unlocked and use any custom rom here, which is really important things for me to have rooted and banking apps run well (magisk)..

Yes, all US998 are carrier unlocked.
But anny H930DS in the world any be bootloader unlocked and rooted and use custom ROM. Because any V30/V30+/V30S in the world can be bootloader unlocked and rooted.
Lots from India, Pakistan, Indonesia (which are all same EAS region) have done so. All the H930DS have fastboot flash commands. You just need to temporarily downgrade to pre-July 2018 Oreo firmware if you have newer than that. Unlock bootloader with WTF bootloader unlock exploit, install TWRP and root.

I know it doesn't have LTE Band 8, but the other one which LTE Band 3 (1800) have it. So, will it work with only 1 band cover it? And does it have affect to signal strength while only 1 working band?
In fact it only have 1 band that works, beside H930DS which cover both of them Band 3 and 8.
The H930DS price here almost twice with US998 version distributed by black market here, so this price comparison really matter to me. I like this phone because it has nice design and of course Quad DAC feature.
And oh, most of the time I live with wifi connection in my house/office.
Really need your best opinion, thanks Matt

H930(Europe V30) has these bands and is carrier unlocked. If you find one that is not for some reason, you would just flash the H930 Open EU KDZ:
If you have"H930" (either actual or converted), you will either have these bands:
2G GSM: 900 / 1800 / 1900
3G (HSPA): 850 / 900 / 1900 / 2100
4G LTE: 1/2/3/4/5/8/12/17/20/28/38

That would give you LTE band 3 and LTE band 8. How are the prices on those?
But if you have to go with US998 for price, then that's what you have to do.

Need some help declaring what varient of LG V30 I have TY<3

Hello everyone and thank you for clicking my question. I just got my girlfriends LGv30 delivered to me today and wanted to make sure I understand the variant before I go for a bootloader unlock since I got it off of ebay.
So the vendor on ebay says its US998 GSM, this is the part that confuses me. He says its only GSM meaning T-mobile, ATT, etc. I thought that US998 was CDMA and GSM?
'''DEFINING FACTORS'''
The back of the phone displays a B&O (Edited, originally said B&W)
In software (in my settings) it says lg-us99820b
fastboot devies brings back
LGUS998c7507e2c
My firmware version is 8.0 may 2018
Will this model be eligible for WTF bootloader unlock?
Thank you all, just making sure to be extra careful so I can avoid a brick
Mate try IMEI info and use your imei to confirm your device model as long as its imei is not changed,also bootloader might also be the way of determining it but I don't recall bootloader's on LG displaying that info

It may say B&O (Bang & Olufsen, stereo manufacturer who helped tune the Quad DAC), but B&H Photo retail store sells carrier unlocked phones and they do NOT have their logos on the back panel. I have three genuine native US998 V30/V30+ bought from B&H Photo.
Whereas, B&O logo means it was not a genuine US998, nor is that back panel from a North American phone. LG does not have rights to sell B&O branded objects in North America. Another company has licensed those rights for North America. B&O branded LG V30 phones were sold in Asia. But don't worry, it's probably only the back panel.
There's some eBay refurbishers who are mixing and matching parts to create "like new" US998 phones.
Doesn't matter what it started as, as long as it's running US998 firmware. It's US998 now.

Most US998 being sold online nowadays are former LS998 -- especially if it's a 128GB V30+. That's OK. It's now carrier unlocked US998 V30+.
This means your mainboard is former LS998, and other parts (like back panel) are sourced from other V30 phones. They have already Frankensteined it for you to US998 firmware.

Yes, US998 has both CDMA and GSM/HSPA/LTE. But:
* Verizon won't let you activate a US998 as it's not a Verizon-branded phone. People get around that by having an already-activated Verizon SIM card or finding a Verizon rep who will bend the rules.
* Until last year (2019), Sprint would not activate a US998 on Sprint network, as it doesn't have 3 Sprint LTE bands. (Sprint finally changed their stance and allowed activation since mid-2019, but Sprint is going away. That brand will disappear in August, after being bought by T-mobile.)
So, anyone who bought a 2017 US998 in the U.S. could really only use it on AT&T or T-mobile or MVNOs using AT&T and T-mobile, while it was being manufactured. Unless you jumped through a lot of advanced hoops 99% of people don't even know exist. Dealers don't want returns or refunds -- so they play it safe by saying it's ONLY for AT&T or T-mobile.

Hmmm... Do you have 64GB internal memory or 128GB internal memory? Native AT&T H931 is only 64GB V30 while Sprint LS998 is 128GB V30+.
As I said, they've built this using parts from other phones. Looks like they have used part of LS998, part of H931 and back panel (B&O) of an Asia V30 to create this "US998". Still it's now a "US998" since it's successfully running US998 firmware.
You would use WTF bootloader unlock and root. It's already been converted to US998, so you have fastboot flash commands and it's already on pre-July 2028 early Oreo firmware, if what you reported is correct.

Wow Im stupid, yes it is B O Not BW. So I declared it was safe for flashing the new_unlock.bin via fastboot flash unlock command and for some reason am not getting a response. I can check if the phone is unlocked and it shows up on fastboot devices. I previously used the WTF method on my LG V30+ way back and loved the results, I just wanted to pass forward the joys of bootloader unlock and magisk to my girlfriend
Do you have any idea what I would do?
Does having OEM unlock on in developer settings make a difference?
Also I am in photomode for usb transfer as suggested.
EDIT:
also if I use fastboot oem device-id I get back
< waiting for device >
...
FAILED (command write failed (Too many links))
finished. total time: 0.004s
which is basically the same response I get when trying to flash unlock.bin
Also 64GB
Also Ive tried the exact same process on debian linux with no luck either

"Too many links" means ADB/fastboot is not communicating well with the phone. 11 of the 12 WTF Section 7 Trouble Shooting Tips are about the V30 ADB/fastboot communication issues.
Go check out WTF Section 7. Different port, different USB cable, different computer, etc. One person had to use 4 different computers...

Glad you got it working. Sorry it's not a 128GB V30+, but your girlfriend will still love the phone.
Flash to last Oreo 20h through TWRP flashable zips to get DTS Surround Sound stereo. You'll need to successively flash 20e, 20f, 20g, 20h all back-to-back in TWRP in one session (you can auto stack in TWRP) + Magisk, then reboot.
Later Oreo has much improved camera, plus DTS libs (but need root). However, you can't just jump to 20h with TWRP flashable zip, there's too many changes. So you have to incrementally update, but you can do it all in one TWRP session.

I totally will do that, thank you for the advice! Ill also do that for my 128 GB lg v30+ (my firmware has been buggy lately. Might be time to start from scratch again.) Do you know off hand what kdz id likely use as a preflash before updating?
Actually it appears that I did that process before as I am on US99820h. Is it safe to reflash only that one (20h) if my phone is already on the firmware or do I need to reflash to a preexisting fw and then update each?
Sorry for the late reply I went to sleep haha.
Btw you are awesome

If you are on US998 20h -- either by flashing 20h full image KDZ or you stacked 20e, 20f, 20g, 20h TWRP flashable zips and flashed those successively in TWRP -- then you can simply re-flash 20h TWRP flashable zip + Magisk to refresh the installation.
The latter Oreo TWRP-flashable zips have DTS Surround Sound build prop already enabled by the Dev (JohnFawkes). So even if you flash full image 20h KDZ, it's advantage to reflash the 20h TWRP flashable zip (+ Magisk). Otherwise you have to go make the build prop changes manually.
If you really want to refresh, you can factory reset just prior to flashing 20h TWRP flashable zip + Magisk. Just don't wipe internal memory,unless you have the zips backed up to microSD card or you can connect to PC while in TWRP to transfer them off.
