I'm new to the LG Ecosystem and I have a few questions.
I have an LG G6 H870 from Entel in Chile, its currently on Android 7.
1) Can I flash it to something like the OPEN EU images which are newer?
Because they're all H870's are they the exact same hardware, meaning the functionality on different H870 kdzs should work fine? The Entel doesnt even have a 2018 release yet so I don't have great confidence they will update the LG G6.
2) Does flashing a KDZ affect the boot loader?
If I unlocked the bootloader for rooting would flashing the KDZ back reset it back to locked?
3) Is it safe to flash a KDZ via a virtual machine? The LG Bridge app wont detect my phone on Mac no matter what I try (High Sierra), (adb is fine iv tried the drivers etc), however it shows up when I connect it to a Windows 7 VM.
4) Is it likely that when the official Oreo 8.1 update comes it would be better to switch to something like an OPEN EU or UK image?
Or even just flash the new 8.1 KDZ when its available?
5) If I rooted and flashed something like LineageOS, can I easily go back to any of the KDZs with the LG tool?
I noticed theres an "error link which seems to download a KDZ for resetting your phone. Does that work off some kind of internal hardware serial, meaning that if things are ever soft-bricked I could just hit that button and go back to square one no problems?
6) Anything else I should be aware of or concerned about if I want to play with flashing different KDZs or custom roms? I dont care about warranty e.g. unlocked bootloader.
7) Whats the best tool for unlocking bootloader and gaining root these days, I know theres a tonne of AIO tools and things like KingRoot. Any suggestions from other LG G6 modders?

1) If it's just an "H870" than yes, it should be fine.
2) You cannot unlock the bootloader. Only unbranded US997 and European H870 can.
3) Never tried, it should, but in this i cannot give you a certain answer.
4) 8.1? We don't know it'll be 8.1. Anyway it's always better to flash the right firmware for your region.
5) You cannot do any kind of modding on your device atm, see the 2nd answer.
6) Flashing a wrong kdz could hard brick your device, so be careful on names. For the warranty you're good to go, you cannot do any kind of modding.
7) For G6 there is no "best" tool, there is only ONE way to unlock the bootloader but it won't work on your model (as explained in the 2nd answer), other tools like KingRoot don't work at all.
Bonus answer: No, flashing an european firmware won't allow you to unlock the bootloader.
Sorry for the noob question, it's probably been asked on here, but have not been able to find a solid answer. I have a US Cellular LG G6, which by now I know bootloader can't be unlocked. But, is there any way to update to Android Oreo? Currently on Android Nougat 7.0. thanks in advance.

I have found out the hard way that there are several versions of the model US997 variant of the LG G6:
https: //lg-firmwares.c o m/lg-us997-firmwares/firmwares/
(I apologize that the forum's spam filters are preventing me from posting a working link. Just take out the spaces.)
There is a USA unlocked version, two US cellular versions, two "Brightpoint" versions (whatever that is), and an Amazon version. And they all share the same model number. This is quite confusing because with most phones, usually there is only one version per model number. If your phone is stuck on Android Nougat, chances are you're like me and you're on the USA unlocked version of this phone, not the US Cellular version. The US Cellular and Brightspot versions have all been updated to Oreo and the latest update was in September 2018.
I have no idea why LG isn't upgrading the USA unlocked version. It was very frustrating when I bought it used and found out it was still stuck on Nougat, which I was not expecting.

Actually the US Unlocked version has gotten the update and it's bootloader unlockable... My phone is the US997Z which is the US Cellular version. I believe you have to be connected to their service to be able to receive the update through their towers. I went ahead a upgraded my LG G6 with the US unlocked version kdz as the @HueyT mentions above. Update went great using LG up and uppercut no set back going through the update. If you need help I would happily help you out. Because I was in the same boat as you.

It's very strange that some versions of the LG G6 "US997" are not updated to Oreo yet and other ones with this version are. But if there is anyone out there reading this, you know know there is a workaround and you can force your computer to update the firmware on your LG G6 with the official LG ROM that runs Android Oreo.
For the $254 I paid for this phone used, with a case and the original charger, I can live with a phone that I have to update manually if I won't get OTA updates for some reason. And I did not break the phone's security because I'm still able to use Google Pay and online banking.

Hi.
I am expecting delivery of an LG V20 h910 from eBay in the coming days, but don't have an AT&T SIM (EU user).
Is there a way to flash an unlocked, stock version of the software (eg US996) so I can update the phone to the latest version?
I heard non-AT&T SIM users don't get updates thru AT&T, so wondering how I can get the latest software for it.
I would prefer not to root the phone, but would do if necessary (and if I can then get a fully functional, up-to-date software version).
Thanks in advance.

First off, if its not sim unlocked phone, it will forever stay sim locked unless you get the network unlock for it. EVEN if you flash any of the other brand roms. Also, AT&T doesn't have the full stock kdz to revert to, there are work arounds to return to stock. This phone has trouble with the screen ghosting/retention, as well as bonkers HDR camera performance, also not to forget, GPS inaccuracy upto 50 meters. I'd suggest look away from LG unless you're going for LG v30 which doesn't carry any of these issues.
If you have already bought, paid and "expecting" shipment anytime soon, you should make sure that its network unlocked H910. (make backup of your partitions before flashing any other brand rom because you will need modem, modemst1, modemst2 and misc partitions in-case you lose the signals). Then you can easily flash it with H915 rom which is the best among debloated stock roms. Flash H910 v10m firmware over it, then flash the modem/modemst1/modemst2/misc files from fastboot to get network signal. From there on forward, you may keep H915 rom with H910 v10m base, or you can even move on to lineage roms. I'd suggest stay rooted with manual color calibration for no-ghosting measures.

You can't flash another variant rom until you unlock the bootloader and root. As far as functionality with the 996 will depend on the bands your carrier supports
Sent from my LG-H910 using XDA Labs
I received my used AT&T V20 yesterday also bought from eBay. I'm on O2 and it works fine. Just be sure your phone is network unlocked. Only thing is the bloatware.
So much misinformation in this thread, but I will just address the original question....
Yes, you can flash the US996 KDZ without rooting .. just flash like you would any other KDZ. You lose some AT&T specific features while running US996, but if you are overseas, I don't think that will bother you.
As far as I know, that will SIM unlock the phone if it is locked. If it doesn't, then the engineering bootloader that you use to root will SIM unlock the phone as well as bootloader unlock it.
So, first try the US996 KDZ, if that doesn't SIM unlock, you will have to root.

The phone should come pre-unlocked for all networks. I'm mainly concerned about system updates. US996 sounds good, as I can't use AT&T here (AT&T doesn't exist in my country). Would I be able to update the firmware in any way once US996 KDZ is installed? Thanks in advance.

No system updates. Had the latest update with the latest security patch, but I downgraded because I want to root it. Still 7.0, but with a earlier patch level.
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.

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.

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)
Hello all,
I'm really new to the phone modification scene. I tinker around with computers mostly. I have an unlocked sprint version of the LG v20, the only problem is I am not receiving data on my new carrier (even with the correct apn added). I'm pretty sure this is a firmware issue. I was wondering if there was a way to flash the us996 or verizon version of the phone to get data to work. I know the sprint version is super locked down. I just didn't know if using a modded version of LGUP and the us996 kdz would brick the phone or not, or if there was a way to flash different firmware on the version I am on.
Thanks and cheers,,

Your firmware has anti-rollback enabled (ARB1), and the US996 and VS995 do not (ARB0), so flashing any KDZ (Sprint does not provide KDZ files at all) will surely brick your phone permanently. You're pretty much stuck with the Sprint firmware you currently have, and the only change possible is taking an official over-the-air update to Oreo, but that could re-lock the phone to Sprint only again.
If you're getting into phone modification, then you'll be much better off with any other LG V20 variant as they are all rootable, unlike the Sprint model with ARB1.

That really sucks, yeah I don't really want to try and hassle with sprint customer support, I got the phone second-hand from my step-brother. So, i'm not sure if they would even unlock it again for me. Thanks for the information. I wasn't sure if there was a way to flash certain parts of the software to possible fix the modem issues or not.
Bought a H871 cheap on eBay and it worked awesome at first..then i got the software update notification to upgrade to Oreo. Thats when it all went downhill. The phone is just a laggy mess now ive deleted the cache and factory reset the phone so many times I lost count now. Nothing has made it any better. Then i get the update to go to pie and its the same story. I've factory reset and deleted cache so many times with no improvement. So my question is how can i go back to stock 7.0. Where all was right in the world. I saw you can use LGUP but I cant find a h871 kdz to flash....thanks for any help that can be provided

Here you can easily find the nougat 7 but my question is that can you downgrade your phone to nougat from pie without unlocking your phones bootloader.....?
the phone is probably damaged internally causing the processor to run slower to keep itself from overheating? no way to downgrade as the at&t firmware files have never leaked nor been made public. best bet is to follow a flash guide to load up oreo from US997 device.
see this guide -->> https://forum.xda-developers.com/att-g6/how-to/convert-upgrade-att-g6-to-h873-oreo-t3791848
please note this firmware will work on AT&T network however you will lose the ability to revert back to AT&T firmware. You will also not be able to use AT&T wifi calling

This is a great question. I believe some users have successfully tried it with Oreo. I tried unsuccessfully with my AT&T H871 but it is currently on pie. I have asked this question for my situation, but so far I have not received an answer. Head on over to the thread referenced above for conversion. You may need to read many pages of posts, but there are some who have tried this with Oreo and may have suggestions for you.
I have an AT&T LG G6 H871 that has been updated to Pie, and I was looking for a way to flash it so it would no longer have AT&T firmware. I live in Canada, in a rural area, so it would be great if I was able to switch the Network Mode to LTE( it favors HSPA signal at the moment) and get rid of the AT&T bloatware. I have tried using LGUP to flash this thing following the steps laid out in various forums, but I can't get it to work. Any help would be appreciated!
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' .
Non Rooted Device
Thanks Indeed,

Oreo update is doable, I have one of mine on Oreo. You just can only temp root if you want, but that is flakey to do.
Did you mean US version of Oreo Or sprint version ?

Im on Sprint and in US.
My phone is working for all carriers , Question is, Installing sprint will relock my device for specifically sprint or will it remains like before flashing ?

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..
