US996 unlocked firmware - LG V20 Questions & Answers

does anyone know what the latest software version that's available for the US996 unlocked non-US Cellular device is? searches reveal there a US99610h, but no idea if it would work on the non-US Cellular version. if it does work, is it root-able?

I check there for update releases. I haven't tried 10g yet. All revisions are rootable. See https://forum.xda-developers.com/v2...y-unlock-v20-root-shell-t3490594/post72591452

something doesn't seem right with my 10h/dirty santa unlock.. just booted into fastboot/bootloader mode and all the version strings are blank and lock state = locked. also the fastboot oem device-id command returns unknown command. Downloading 10h kdz now.. I just want the official bootloader unlock to work the way it was supposed to.. main reason I bought this model over H918
C:\Windows\system32>fastboot getvar unlocked
unlocked: no
finished. total time: 0.057s
I am running WETA 5.0.7 right now so dirty santa must have at least partially worked

WTF?! So LG registration says "Carrier: ulocked phones" based on IMEI, but after reflashing us99610h from LG-Firmware's site, re-entering fastboot mode "looks correct again", obtaining the device-ID.. LG bootloader unlock tells me this "unfortunately your device (US_CELLULAR_TULSA(USA) does not support bootloader unlocking.. this device-id better be based off of this ROM being a USC based one or I'm going to be livid! Going to flash the 610f now and see.

Hey, I have the US Cellular V30. Same model as the unlocked V30. Are you saying that you flashed something to your V20 that made the LG Bootloader Unlock website think that it was a US Cellular Version? Do you think the IMEI or the Device ID was changed? I ask because I'm wondering if flashing the Unlocked v30 KDZ will make my US Cellular Version operate as if it were the real unlocked version.

As far as I could tell with the v20 is the device IDs are hard coded and LG can differentiate the USC from the unlocked models.. so even flashing the unlocked kdz didn't change it allowing a factory LG bootloader unlock

In a conundrum
I am try to take a lg v20 vs995 and flash lg us996 trying a few different things a kept getting radio off. Tried *#4636#*# service menu settings. Turn radios on . But won't actually turn on. Keep getting messages " Radios off" Turn off airplane mode. So I saw your guy's post. And wondering if is possible to take lg vs995 wipe it clean blank , delete all partions , repartition , the flash a complete new operating system. I want to make mine a Lg Us996 unlocked version. Removing all parts of Verizon.

Undefeatable Boot loop :(

I was comfortably running WETA rom on my US Cellular US996 and I decided to install Magisk so I could use Android Pay. Doing so only allowed me to boot into Fastboot and Download. So I put in download and flashed the KDZ for it. It worked for about 5 minutes and then I was greeted with a static screen. I then re-flashed and now I get a boot loop that i cant escape. I have flashed both the 1205 and 1216 kdz files, as well as a bunch of factory resets.
The boot loader is now locked as well.
Any help is appreciated. I have gotten kind of attached to this phone and have assigned sentimental value to it. I would really hate to rid of it.
Thank you much!
Anyone?
US99610f_00_1205.kdz is intended for the Unlocked (Non US Cellular) variant of the US996
US99610g_00_1216.kdz is intended for...supposedly...a "Brightpoint" variant of the US996
You should probably try out US99610h_00_0413.kdz which are intended for the US Cellular variant of the US996. Hopefully you have better luck with that.

Without an unlocked bootloader I don't see much else that can be attempted. While I doubt it would work, you could try to flash the Unlocked US996 KDZ and then attempt to unlock your booatloader using LG's online tool. I've seen a report that the the LG website was flagging someones phone as the US Cellular variant when they flashed the US Cellular firmware onto their Unlocked variant. Possibly you could have some luck the other way around making LG's website think your phone is an Unlocked variant. If that works, you could possibly unlock your bootloader and try some more additional steps.
Another option is to open an RMA with LG. I've heard of them being pretty lenient on bricked phones due to root attempts.

LG G6 Using different KDZ's

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.

Just use the US997 and NOT US997U and it'll work perfectly on non-US-Cellular or US-Cellular KDZ. 21B is latest Oreo

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.

Unbranding h910 AT&T

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.

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.

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.
Hello everyone,
I just bought a LGV35 form eBay for a few bucks but has bad imei is there any chance that I can unlock the phone? I want to use it outside USA, any idea or can somebody help me?
Regards

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.

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.

How did you go about unlocking it? Did you buy it from ATT without a contract.. Did you use an unlocking service or from att directly for unlock?

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)

V20 LG Official Unlock..

So, I happened to get my hands on a pair of V20's. Both were us996 models. One was the USA and the other was UCL (US Cellular). In the past, the UCL was not able to be unlocked on LG's website. I was able to unlock the USA model just fine this time. I've tried a BTP model in the past and was not able to, and knew also the UCL was not able to as well. However, I tried anyway. The first hurdle was the IMEI # is 14 digits, which you need 15 digits for it to unlock correctly. (Typically 14 is ONLY CDMA), which UCL is.
This gives the full 15... https://www.imei.info/calc I proceeded to follow LG's guide, going to fastboot, then fastboot oem device-id And guess what, I got a valid unlock.bin from LG and was able to fully unlock the previously unlockable model us996.UCL. (which is not on the list of unlocked still, only us996.USA).
I then flashed my us99610n.zip (The 20f was installed, so needed to downgrade). The phone boots just fine now and works for GSM/CDMA like any other us996.USA device. It presents the yellow warning, vs. the red stop alert.
With all the said, I'm not sure if ALL V20 models are now unlockable, but others will have to try. Ie.. vs995/h990/ls997/h910. I know the h918 was already was, but some fastboot commands were missing. So if anyone else wants to try and report back. You may not even need to really flash the unlock.bin file, more so LG's website initially would not even email the unlock.bin file if it was not able to be done.
LG's Guide: https://developer.lge.com/resource/mobile/RetrieveBootloader.dev (you need an account)
You need to make sure in developer settings to enable OEM unlock. YOU may need to go back to stock to get this option to enable it. Not sure coming from Lineage what will happen.
EDIT: Fortunately I had saved my device-id and IMEI before I rooted so I didn't have to flash stock to test on VS995. I had a 15 digit IMEI without having to find the 15th digit.
Unfortunately it didn't work. I got a model not supported message on the LG developer website. Hopefully it will work for everyone with a UCL model.
Original Post:
I am unable to test this on my dirtycow rooted VS995 because "fastboot oem device-id" does not work presumably because of engineering aboot. EDIT: I see now you did mention this OP.
I get this:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot oem device-id
...
FAILED (remote: unknown command)
finished. total time: 0.073s

I suppose I could flash stock to see if it works on my spare device if no one else tests this on non us996 variants in the meantime.
Would be fantastic if it works! Great as it is because at least UCL versions are easier to come by than the USA version from what I see for sale online.
I have LG V20 F800L. Fastboot mode is also not available in it. You can unlock the bootlader method DirtySanta ( XDA [LS997|VS995|H910|F800L] DirtySanta Bootloader unlock and Root guide )
This is interesting. Nice find. Hopefully the door can be unlocked. Ls997 for me lol. One fully rooted, one temp root on Oreo, and other Unrooted ZVD.
A user on the V20 Subreddit got the US996 BPT unlocked via LG. So now it appears that at least all US996 models (USA, UCL, BPT) can get their bootloaders officially unlocked through LG's website.

Not all, but I wish. I have a US996 UCK model (US CELLULAR_TULSA(USA) that this doesn't work on:
"Unfortunately, your device( United States, (US CELLULAR_TULSA(USA)), LGUS996.UCK )does not support unlocking the bootloader. Your account will be locked if you enter the wrong information more than 9 times." (down to 7 now - LOL.)
My IMEI is already 15 digits (vs 14 as noted), so no need to convert/find the check digit. This is just a standby phone, but it would be nice to unlock it without using the engineering BL/DS method. Same holds true with a pair of VS995's that I have.
Perhaps I overlooked something?
EDIT: I have another US996 device coming next week that "appears" to be the real McCoy (Carrier Code: USA) according to the IMEI . Hopefully this one is legit.

Interesting to know. I haven't heard of the UCK variant before. Does it say UCK next to the barcode on the sticker behind the battery?
According to the LG firmware page, it looks like there's even a 5th region called BPS (another Brightpoint model) for the US996. So I guess we still can't go buy US996s blindly for the official bootloader unlock. No surprise about the VS995 as Verizon (along with AT&T) had locked bootloaders on their phones for ages now.

Yes, UCK on the sticker. Just for kicks I flashed the USA firmware US99610f_00_1205.kdz in hopes it made a difference, but it returns the same unlock string.
I tried it with a H990ds TWN and it did not work ("Unfortunately, your device..."). That was to be expected, but I tried it anyway just in case.
I had a US996 that I previously could not unlock.
The error said something in the lines of this model US996Z is not supported.
I tried the LG developer site again today and it gave me an unlock key.
Thanks for the heads up ?
I noticed that the LG developer site now has a pop-up message saying that it will terminate at the end of the year, so all official bootloader unlocks will no longer be possible after that. Anyone who wants to root any of the supported US996 models after this year would need to do the DirtySanta process.
