Awesome find! /kappa
Most models have this option, but it does nothing for us without fastboot, for now..

I saw this in the options, but wasn't sure how it helped us. What is the plus value of doing this? Does it permit to fasboot oem unlock?
**Edit** Read up on it. It only enables fastboot, which you could do once root was achieved anyway, so no big exploit. Anyone courageous enough to attempt to bootloader unlock the sucker?

I thought they all had this option but the T-Mobile variation was the only one where it actually did anything?
EDIT: I attempted to enter Fastboot with Vol-Up and Power without success.

To my knowledge the only G4s that are unlocked are the TMO (811) and International (815EU) everyone else, that option is a dummy option. the reason thats there is because that option is a default dev feature in LP. Checking this unless you have either of the two listed variants has no effect. It makes you able to use the fastboot oem unlock command which is only supported on these two variants.

Has it been confirmed that the Canadian version has a locked bootloader? Or would it be carrier dependant? There just isn't a lot of people, understandably, talking about the H812.

Connect your phone to your pc, and run this command in terminal: adb reboot bootloader
if it puts you in fastboot you can issue this command: fastboot oem unlock
if you can't even enter fastboot, then you device bootloader is locked.

Confirmed: Does not work. (Telus H812)

Confirmed locked, Rogers H812.
Worth a shot anyhow I suppose

Well... At least we're one step closer to getting root on Canadian variants. It's a step in the right direction at least.

This is a standard Android option. it only works on a couple of devices. T-Mobile is one. It's definitely not a quick and easy fix to unlock your bootloader for 95% of people.

Ah well, I can certainly live without flashing a new ROM. LG's take on Android isn't as absolutely foul as Touchwiz was on my S3. I'll be perfectly sorted once we have access to Xposed, Viper, and the other incredible applications that require root.

I guess if it just restarts as usual after issuing the command then the bootloader is locked.
Talking about MTS H812.

Has anybody bugged LG about unlocking the bootloader recently. Last I see is that they unlocked 815 and others were to follow.
I did, however, find this: https://www.change.org/p/lg-electronics-unlock-bootloader-on-all-g4-devices

ETA ?
Is there some information about possibly having support for CM on the H812? It's suck that LG don't seem to want to unlock the locked Canadian and European variant of the G4. If I would have known that earlier I would have went for a Nexus 5 or 6 and not a G4 :/

Not sure where everyone is coming up with this uninformed bullcrap that if your able to boot into the bootloader you are unlocked. The boot loader on EVERY single G4 is LOCKED until you have LG provide you the unlock.bin, after giving them the Device ID from fastboot. If you own an H811 from T-Mobile you can unlock without the unlock.bin. If your lucky enough to be able to access fastboot on other models, it just means you are able to obtain your Device ID for the day LG decides to support the US models. End of discussion, nothing more to talk about!

I've recently contacted LG Canada about releasing an unlock tool for the boot loader on the G4 Canadian variant. I conveyed to them that it is one of the primary features I look for in a phone (I have the G2, G3 and got the G4 in expectation of eventually getting to install other ROMS). I've not received a response yet.
Given that the hardware features are gradually becoming indistinguishable between vendors (and LG is no longer on the world wide market share short list), one way to differentiate yourself and place yourself apart from others is to permit the user the ability to do as they wish with the phone, especially when the costs to maintain future OS releases becomes onerous and unprofitable and developers and open source communities are willing to pick up where vendor left the phone to wither and die.
I had advised them that the G4 will be the last LG phone I will be buying if this is the stance they take.

I gave up on this phone, it's out for hardware repair right now, I'm not even anxious to get it back, I'm enjoying my old unlocked rooted s4
Sent from my GT-I9505G using XDA Free mobile app

Well, that is disappointing to say the least.
I am bought the Canadian LG G4 without even anticipating that it wouldn't be unlocked. I had a LG G3 previously and was generally happy with the phone. Lesson learned I guess. I'll make sure my next phone does not have a locked bootloader, and LG won't be on the list for my next device.

LS997 wave lost

Has any find a way to fix the issue with the latest ota update on the sprint ls997. its saying invalid sim and cant get into the bootoader so no root or even into the hidden menu option

What do you mean by "wave lost"? In order for people to help you, you need to detail what exactly you are trying to do, what you previously did before issues arose, and what is currently wrong with the phone. The ls997 doesn't have an unlockable bootloader or fastboot commands, so there isn't anything you can do from the bootloader.

After updating my lg ls997 to ZVC firmware and resetting the phone its saying invalid sim so no network service cant load into boot-loader either or go into hidden menu. I cant make or received any calls or even flash a different rom

Ah. There's a thread somewhere by runningnak3d that details the issues people are having with unlocking the carrier variants. If you are using the ls997 (Sprint device) on another network, many people have been reporting issues with the unlocked state resetting upon updating or wiping the data partition. Many of the people have root though, so they can either downgrade their firmware, or try different modems. If you're not rooted currently, there is no way to do this at the moment for Sprint devices with zv8 or higher due to antirollback being enabled. Here's the thread https://forum.xda-developers.com/v20/how-to/hardware-modem-modem-firmware-ril-t3744860

@Zhanozuki Are you using your phone on a network besides Sprint? If so, was it working before you took the OTA update?
Also, were you rooted, or were you asking if there is a way to root?

Yes i was using it on different network in my country which is "Digicel". i didn't have root because i just received the phone after purchasing it off eBay. I didn't get time to root it i just put in my sim using it for 3 hours saw the update went ahead and update then reset when i lost network:crying: now my phone is useless

Hmm. @runningnak3d this is almost the exact same situation that happened to those us996 users from England. They took the 10n ota and suddenly their phones could no longer connect to their network. One of them sent his phone to LG and it was found that there were non-LG parts in the phone that would cost 378 to replace. Some of these refurb phones being sold by not reputable vendors are replaced with knock-off Chinese mobos and parts that break very easily. May not be the case here but just a thought.
Here is a link to that thread https://forum.xda-developers.com/v20/help/lg-v20-us996-radio-off-security-update-t3718507

It think it much more likely that the Sprint modem had bands enabled that Sprint doesn't use, and they sent out a modem that disabled those bands.
OMG OH NOES someone can use our phone on another network -- hurry up and disable that!
Super Di**s

Ls997 ZVC to US996?

Is it possible to safely flash a us996 unlocked rom onto my ls997zvc? And will it allow me to continue to use my gsm att based sim card? I bought this phone used the other day. He said it was Verizon unlocked but turns out its this sprint model. No carrier branding anywhere. No splash screen on boot. I almost thought it was a non carrier based unlocked phone until i looked up the model number.

Bump
Buuuuuump. I bought my phone through sprint, paid it off, they keep telling me It's unlocked, but i have to factory reset every time i turn my phone off to get it to work with the other carrier sim. I've contacted them over and over and all they say is "we sent the unlock signal, that's all we can do on our end" but their signal is only working on factory reset. I really want to root this and install the unlocked firmware so i can have my phone without having to reinstall everything constantly. I mistakenly upgraded to ZVC update before having it unlocked and now I'm stuck. Any updates on an unlock eta?

Unfortunately I believe that ZVC is ARB 2 and it has the latest lafd with copy2 pulled, so that means that even once the lafsploit is finished, the LS997 will not be able to use it because you can't roll back to a firmware version that has copy2. If I am wrong, and ZVC is still ARB 1, then you can roll back to a version that has copy2.
If I can find a dump of the ZVC firmware, I can tell you for certain what ARB version it is. If no one has made a dump, you can do it yourself by grabbing the patched LG UP, and used the dump option. If you grab one of the full stock flashable zips from another model, you can see what partitions need to be included. I could just tell you, but I think people need to learn

I accidentally updated mine to zvd the other day. A brand new release. Would be very nice if you could tell me exactly how to flash the us996 firware safely. Ther3 has to be a way to unlock this damned phone. I paid 200 for it and now i am ****ed.
Please help me out. I could post a dump of the zvd firmware if i can figure it out

@me2151 Welcome back dude
If all goes as planned, we will soon be able to root any model on any ARB version. My info above about ARB 2 being an issue was incorrect (must have been on crack when I typed that post).
LG phones with unlockable bootloaders (or that have an engineering aboot / abl) will be rootable indefinitely -- a hole that can't be closed without changing their security significantly.

Please keep me informed on your progress. I really just want to do this to gsm unlock my phone for my at&t sim card. Guy sold me it saying it was unlocked already.
Do i have to root to flash us996 rom onto my phone? And does that unlock it or the root method from dirty santa exploit what uicc unlocks the phone. I read tidbits of information on this forum that say the phone is uicc unlocked after rooting and/or flashing us996 firmware, but all are supposedly only possible on zv7 or older firmware of Sprint phones.

Hello, I'm here with Ls997 ZVA, ARB=1 and are waiting for any update from you guys.
Thank you ^^

Does anybody know If i can do the similar thing but towards using TMobile network?? Can I flash Tmo H918 stock rom to LS997 Sprint variant?? I just want to use my Tmo Sim, or maybe if my LS997-SVC still a problem?

2 years late but better than never I suppose?
No idea what my LS997 is using. Performed the dirty santa a long time ago to root, and just this morning I flashed /e/OS over Lineage to test the waters with a de-googled experience. I'm now on T-mobile magenta max plan following the merge and daily driver is a Pixel 4A 5G. Popped the SIM into the V20 running /e/OS and data works but voice and text do not. Not sure if this is a hardware, firmware, or software incompatibility.
Honestly the V20 really pissed me off with how locked down it was. I am NEVER buying a phone that is not easy to root or repair. that is 100% deal breaking for me. Pixel phones have unlockable bootloaders so not too much bull**** necessary to break from the clutches of these damn phone companies and carriers.

Any way to carrier unlock the AT&T V35?

Without AT&T's help?

No, you can contact AT&T, https://www.att.com/deviceunlock

Yes you can. I've done it with a site called unlockplus.

Here you go. Flash one of these KDZ to carrier unlock the phone. You want the ones that say "open" -- which means they are not locked to a carrier.

Bottom link is for Central/South America -- but if you use that, you do NOT want Claro. You want the other one (carrier unlocked) MIA.

Just so you know, you're replying to a guy who (besides other feats) made it possible for anyone to carrier unlock virtually any LG V30 model no matter what carrier it was on previously. And that was made exactly by crossflashing. So yeah, I would kinda listen to him.

Because that's EXACTLY how we carrier unlock the LG V30/V30+. We flash carrier unlocked firmware over carrier locked firmware -- specifically AT&T and Sprint variants. The principle should be the same with the AT&T LG V35.
Besides the two carrier locked North American LG V30 phones (AT&T & Sprint), some of the European LG V30 are also carrier locked. Cross flashing the region appropriate "open market" firmware carrier unlocks them.
I haven't done it on LG V35, but I've done it many, many times on the predecessor LG V30/V30+.
We flash V30 firmware and forth at will to carrier unlock the phones, get fastboot flash commands, bootloader unlock, install TWRP and root. The simplest of all these goals is carrier unlock.

He says it won't work. Whereas I've carrier unlocked several LG V30/V30+ doing EXACTLY that. And so have hundreds of other people. I've written a couple of guides on the subject.
While I've not done it on LG V35, I suggested this method because it seems reasonable and logical based on the immediate V30 predecessor.
Something similar (cross flashing) also worked on the LG V20. However, in both cases we had Dev Patched LGUP to use. IF it doesn't work for the LG V35, that would be why -- because perhaps the appropriate .dll has not been used to create LG V35 dev patched LGUP.
I can't guarantee it will work on LG V35, the way I can guarantee it does for the LG V30.

lg V35
You can flash it and it will boot (not dead, frozen or stuck in Qualcomm 9008 mode like when you normally flash mismatched firmware, picks up signal fine)
Yes I am aware of how to unlock G6, V30 and G7 by flashing a different firmware and I have unlocked several HUNDRED of them. Even LS998 on V22B firmware.
This will flash successfully (I use Octopus tool, the newest LGUP tool is not released so can't do it that way) but it will still show the V350AWM model and will still be locked to AT&T. Only it will remove the AT&T bloatware.
It is a good solution to flash these if you brick your device. But it won't unlock them.

1) Well debloating V35 is at least one advantage others will like, even if it won't carrier unlock it -- and this answer is much better than your first attempt. Can you also now access the bootloader on the V35 and do fastboot flash commands work when, once you flash the open market KDZ? Cross flashing carrier locked North America V30/V30+ to open market US998 allows this, besides carrier unlocking them.
2) If you are aware of how to to carrier unlock AT&T H931 V30 and Sprint LS998 V30/V30+ by flashing different firmware -- like to the US998 V30 open market KDZ -- as well as other LG phone series (G6/G7) using the same technique, and you say you have carrier unlocked "several hundred" by using that technique (with Octopus box, it seems), then your previous insulting post looks like it was written by someone totally ignorant of this Frankenstein process which we use every day to carrier unlock phones like this...

I have pulled the RSA certs from every model V35, G7, and V40 that are currently available, and LG learned their lesson from the WTF V30 exploit .. they use different certs for every model.
If you have cross flashed the V35, or G7 .. you are only flashing boot and system. If you had flashed an RSA signed partition, you would have had a brick.
I will be glad to post the certs if you like.
-- Brian

Oh sorry I didn't mean it to be insulting at all but flashing these files will not unlock it.

I'm new on this forum. Sorry for being disrespectful.. Everyone is very thankful to you Only WTF? Why would you suggest to flash something if you never tried it before?
To flash I did flash these firmwares but I used Octopus box (super highly recommended)
Lets do something constructive here though. If you have signed cert files let me test it. I have a couple AT&T V350AWM, we can brick them, it is OK. I'll load anything and post results here.
Again sorry about insulting retort but a forum like this should have only 100% clean reliable info.

Interesting, since the G7 and even V35 was released before V30 WTF was discovered (mid-May 2018). @TxanMoe started the WTF thread with his "crazy" story May 14 -- and you helped him unbrick his phone soon after that. I wrote the WTF instructions on May 21.
Well, V35 was released beginning of June 2018, but it was already in the pipeline by May 2018.
The RSA stuff for every variant is probably more an extension of what LG started with T-Mobile H932...
Very sad.

Well, let me clarify. I have only been able to check models that have a KDZ that I can pull the certs from. Any model that either never has KDZ (AT&T or Sprint), or if a KDZ isn't publicly available yet .. I haven't been able to check since I can't get anyone to dump abl.
I will try to post a list of the ones I have checked when the holidays are over.

If you put an AT&T MVNO sim in it, it should update. When I put a Red Pocket Mobile (MVNO) sim in my v35 along with wifi working, it updated the software to version V350AWM10w even though the phone was not yet activated on the red pocket network. If you can find a pre-paid AT&T sim, it should also work, but I'm guessing there.
(note, my v35 is locked to AT&T, I wonder if your phone being unlocked might have some other 'thing' that might be stopping it from updating)

Updating LS-997 Help

I have got LS-997 model and software version is US99610f (Nougat). I want to update it to oreo since its a tempered device all sims are working globally all bands are working too, FOTA updates didn't came to this device. I wanna know that if its safe to install US oreo firmware on LS-997 ? Or not. This is the only option left since no kdz is available for sprint models.
I tried to check bootloader it says your account might get suspend, 9 Times Left bla bla ... and fastboot bootloader variable says unlocked = 'NO' .

As for carrier swapping, I am not sure, there are some other forums on here that are talking unlocking carrier after Oreo Sprint so I am sure it can be done if it happens to relock. I would double check before attempting. Here is one thread... https://forum.xda-developers.com/v20/help/lg-v20-ls997-successfully-unlocked-oreo-t3835061/amp/. Don't update until read though. Just use caution.

You are Right I will share my experience soon

It looks like you have an older, rootable LS997 that has been cross-flashed to US996 Nougat firmware, essentially a Sprint V20 disguised as a US996 that is SIM-unlocked. You won't be able to install the official LS997 Oreo update until you go through the DirtySanta procedure and then flash an old Sprint Nougat ROM near the end of the process. However, after you update to Oreo this way, the phone becomes completely and irreversibly unrootable, which pretty much defeats the purpose of the DirtySanta procedure, so I highly discourage you from doing this. The Sprint firmware is not really useful for anyone who doesn't use Sprint as a carrier.
If you want Oreo or higher, you're much better off installing one of the LineageOS-based ROMs.
One thing I haven't seen anyone do on an LS997 cross-flashed to US996 is trying to flash a US996 Oreo KDZ firmware file. No idea if that works or not, but it would be quite a risk to try since there seems to be no documentation of anyone having done that before.
For more details on just about anything related to the LS997, I've written up a bunch of information here.

If you want full root don't update to Oreo if you are on a full rootable firmware still. All up to you of course. My full root is still Nougat, a Sprint ls997zv7 firmware

Yes thats what I thought exactly .. I found a forum someone did that and he flushed his imei modem completely and there is no way that he can reverse Plus Unfortunately No firmware is available too make sprint phone work again..
