Doing hours and hours of research and fact digging, I guess either I've read the wrong things, or haven't found the right thing to read, but my question seems simple enough.
My Phone: AT&T LG V40 Thinq
Software Version: V405UA10n
Android Version: 8.1.0
Kernel Version: 4.9.65
Build Number: OPM1.171019.026
Android Security Patch: March 1st, 2019
There appears to be no known root for this device, I actually paid OneClickRoot to root my phone, and received a refund just as fast. In my looking around, I noticed that you have to have an unlocked bootloader to be able to root your phone, now with this being said, the European model: EU LMV405EBW does have the availability of an unlocked bootloader and the availability of root.
I downloaded the kdz of the EU LMV405EBW and before I go jackin everything up, I want to know if it's at all possible or "just a given" that since the phone can be unlocked, will my US AT&T sim card work in the unlocked EU version of the phone...?

AFAIK, i still not find any dll and lgup which compatible with lg v40.. it makes me sad since i still not be able to flash the phone which stuck in december 2018 security patch (HK version). So, we might have to wait until someone comes up with an idea which i doubt they will cause this phone is soo underrated.

I had a similar situation, I had a lm-405ua that I wanted to flash to a TW 405ebw firmware. I used the information from https://forum.xda-developers.com/lg-v40/how-to/guide-lgup-root-t3967858 and all went fine.

Hi. I'm having the AT&T version (LM-V405UA). Can I cross-flash firmware on this model? If so, what kind of firmware (name, type) should I need to pay attention to? Thanks.

You can read the link above I provided on info regarding cross-flashing using LGUP.
In terms of what you flash, what is the problem you are trying to solve by flashing a different firmware? In my case I wanted a regional firmware that supported voice over wifi with my telco.

Hi,
End of January I bought a P10 SIM free from a major UK retailer.
It is stuck on March 1st 2017 updates, with no updates available.
I contacted Huawei support - they say my IMEI should be on B162. But I get no update OTA, and even through the HiSuite app it says I have latest.
They said I have to send the phone back for 2 weeks and they will factory reset and upgrade. This is unbelievable to me.
They told me if I use the firmware finder app I would void warrenty. But I thought if I do not root and install the authorised firmware version (B162) then they wouldn't know or it wouldn't be a problem.
I am a little confused by the number of different firmwares in the app, many with the same version number. How do I know which to use? What is the difference between OTA-MF and FullOTA-MF (from the sizes I guess full is full and other is incremental).
Will any of them get me back on the official upgrade path, or if I do this will it be manual updates forever from now on?
Do I have to root to install the firmware from firmware finder (I think not?)
I always thought people who focussed on stock android were silly, and I quite like EMUI but I am really regretting buying Huawei now.

depending on your CUST code you'll have to claim contact to your brand... I mean if your rom is "customized" by the carrier is not only Huawei but also the carrier who has to work on the update the other option depending on your model is to Debrand and change the firm to L29C432 and get the updates of the official but be careful about bricks or Sim detection problems...read all threads talking about debranding and go ahead if you feel confident to avoid a brick

Thanks. It is retail SIM free non-branded. Ie just bought from a store nothing to do with any carrier. I don't really understand the difference between L29 and L09. Mine shows L09 at the moment. Are they different hardware versions?

Hardware is (almost) the same. L29 allows to use both sims in the sim tray.
Just to update.
I used Firmware Finder to install B186A update. Worked perfect and have January 2018 security patch level.
The more recent B185 firmwares are rollback firmwares for downgrading from Oreo. Check the release notes carefully and make sure you chose an upgrade firmware (not a rollback firmware) that is authorized for your IMEI. (For me B186 was not approved but B186A was).
None of the Oreo firmwares were authorized for my device.

Were you able to simply download the firmware from Firmware Finder and install directly? Were there any other steps you had to follow to do this correctly?
Reason i ask is that i am in same situation as you were. Purchased Sept 2017 via O2 in the UK, no updates at all (still on L90C432B113), contacted Huawei and O2 about Oreo with no possible updates and showing March 2017 Security Patch Level.
Getting sick of waiting and looking to move to Oreo as soon as possible.
Any tips would be helpful - thanks in advance.

Sorry for the delay getting back to you.
I was on B120 with a Serbia certified P10.
I installed B186A from Firmware Finder. (at the time I did it B185 was not approved). Its important to do the check with the IMEI number within the app to see if the firmware is signed for your device. I did the proxy method, where you set the proxy, pause download at 5%, unset proxy and it worked very smoothly.
I think the main thing is to make sure you chose an upgrade firmware and not a rollback firmware. They are not labelled clearly and the only difference is in the readmes so check carefully. There are a few more recent B185 firmwares which I found confusing, but they are for people who need to rollback from orea (and so reset the device).
A couple of days later I got Oreo B365 over the air (not through the app). Upgrade went very smooth.
Big improvement in battery life and overall performance better all round.
With Project Treble in place I hope updates will be quicker, and maybe even easy to install stock one day.
Hi guys. I bought an unlocked Sprint LG V40 (V405UA). I am from Argentina and it works perfect in my country with my SIM card, but the problem is that it has the Sprint firmware and it is in Android 8.1 and it won't update if i am not with Sprint contract i think. I'd like to have the stock global firmware and get OTA updates (Android pie at least). I see a page called "lg-firmwares.com" with all models firmwares and tutorials, but i am noob in this matter and i don't want to "brick" my phone or lose the unlocked condition. If i follow the "lg-firmwares.com" tutorial and flash the Android pie firmware for my model, can i brick my phone or lock it again? or it is secure and everythink will be ok?
Thanks.

Okay you have 3 ways to do this.
1st. If rooted/Unlocked Bootloader: https://forum.xda-developers.com/lg-v40/how-to/guide-crossflash-unlocked-pie-to-t3944359
2nd If rooted/Unlocked Bootloader: https://forum.xda-developers.com/lg-v40/how-to/guide-make-lg-v40-compatible-lgup-t3953120
3rd I personally haven't tried this yet: https://forum.xda-developers.com/lg-v40/development/lg-1-16-t3967559
With the 3rd one you should just simply be able to flash any KDZ but you should make sure it's compatible first.
But once you Crossflash no more OTA's you would have to download NEW KDZ and flash it over the one your on.

First at all thanks for your reply. I have some questions for you if you can answer me.
1) is imposible for me get OTA updadates since my phone is not factory unlocked?
2) can i lose my unlocked condition if i flash other firmware?
3) is required unlock my bootloader and root my phone?
4) will all my phone data be erased if i do this?

https://forum.xda-developers.com/lg-v40/how-to/guide-lgup-root-t3967858 This Guide i made should help you with your 3rd question. That we have seen no you shouldn't loose Sim unlock if it's factory unlocked or if you carrier unlocked it for you after so many months being active with them. You always loose your data when KDZ flashing. You wont get OTA updates if you Crossflash...if you stay with your current rom OTA's should be possible
If you're using a us carrier phone outside of the us, you should just forget about ota. It won't work. Do yourself a favor and learn about the various flash methods. You're gonna need one of them at least to keep it updated.
Thanks guys. It sucks that it's imposible for me to get OTA updates, but at least i can try flashing my phone to keep it updated. I will check the guide and learn more about it then. Anyways i think this is an amazing phone and a bargain for the price nowadays..

Hi i am new here and need help with updating my Samsung note 9 i still have a baseband N960USQS1ARI5 but will like to update to the latest firmware. i'm using an unlocked AT&T phone. can anyone guide me? I'm not sure if updating the firmware will lock the phone and the process to update, do I just update the firmware in stages as the updates were released till i get to the latest update or can i update straight up to the latest? I am thinking of using Odin, is that a safe way to do this? any help will be appreciated. Lastly, can I change from the AT&T firmware to lets say a none carrier based firmware so as to stop seeing the AT&T logo on boot up? Maybe switch to a firmware that supports global or international? Does anyone have links to an unlocked firmware update i can use, as well? Please help!
I must state that the phone never updates automatically as it always says the software is up to date.

to your last point, at&t phones are notoriously bad at updating
factory unlocked phones will remain forever unlocked and phones unlocked that are bespoke to a specific carrier will also remain unlocked even with Odin flashes providing that the method employed to unlock it was legitimate. Some unlock methods employ root and only trick the phone into thinking its unlocked. Well, once you remove root, and thusly the trick, the unlock is gone. I have ran across rare examples where the person swore up and down that they unlocked their phone with a legit unlock code and that it relocked to a carrier once the sim was inserted and initial programming completed, but i dunno. Sounds weird to me, but every person who said this also said that the phone locked to a carrier other than the one it came from originally. Take that for what its worth, but i still mostly stand by the first couple lines of this section of my diatribe
If you want the at&t crap gone, get the N960U1 firmware and flash it in Odin. You will need the modified version of Odin to flash it so it can ignore the 255 errors the phone throws up from flashing firmware for a carrier (or, in this case, no carrier) on to a phone that it wasnt originally designated (not designed) for
go to sammobile.com/firmwares, get the info for the firmware you want to d/l, get the Frija tool or Samfirm and download the firmware thru one of those as theyre literally 5x faster and flash it

Hi, my phone is a Note 9 ATT factory unlocked.
Below is the link for my post
I've updated my phone using the link , and still unlocked and working Ok.
I hope it can help you .

I have a Sprint V40 crossflashed with an unlocked V40 kdz, version V405UA20e. I thought OTA was supposed to work with this, but it looks like there have been several security patches since this one dated January 1, 2020. Was I mistaken in that assumption?
I think that if I flash the latest security patch release with LGUP it'll wipe the phone, so I'd like to at least wait for Android 10 before doing that unless there's a way to preserve my settings or somehow fix OTA. Thanks in advance.
You are mistaken. I have the unlocked version of the V40 Thinq and I can confirm that there has not been an update since then. I recently crossflashed with the EBW version, Open United Kingdom flavor because I was tired of waiting for Android 10.
Hi all, I'm new to modding in general so there's many things I don't quite understand, hoping somebody can help.
I bought an S10 from a site which was supposed to just send me a refurbed (italian) S10, instead they sent me the US version, (G973U) and I believe it is carrier locked since it's stuck with Android 9 and doesn't find any update.
I have tried searching to no avail what I should flash to simply unbrand it, and allow it to receive OTA updates without tripping Knox.
The build version is the following: PPR1.180610.011.G973USQU2ASGC and the CRC is XAA/XAA/ATT
Thanks in advance.
You shall call them.
Who and what for? I'm past the point of dealing with those sellers, I just want to flash the phone.
CSC (not CRC).
XAA is a multi-region USA ROM, so I don't think it will change over properly for you in Italy. There are threads here for how you reflash a different ROM. The one I used for my S10+ was this one: https://forum.xda-developers.com/t/...e-links-and-flashing-discussion-here.3905897/ but I am sure there is one like that for your S10 non-plus... find it, follow the instructions, and you should be all set.
Thanks! I'm a newbie, what does it mean it wouldn't change properly? No OTAs? Tripping KNOX?
I have found this which seems to be the equivalent of the link you posted.
So, I should flash the U1 version right? However I see only a file "SAU - 1 - ....", and my build number doesn't end in that, furthermore I don't know which bootloader version I'm at.

Oh ok. I couldn't understand first.
For that, You'll flash in EDL mode. But the problem is if your device is powered by a snapdragon chip, it'll not working seamlessly.

No problem. I'm aware of the mode I have to enter to flash, as above I'm trying to figure out which stock rom I should flash to avoid tripping knox, and to receive OTAs. What won't work seamlessly?
Well, mods can close the thread, found the way to do it. Leaving it in case somebody ever needs it.
First, found & checked the bootloader version (5th number from the right in the build version) since you can only flash older bootloader versions apparently.
Then downloaded through Frija the rom for the unlocked phone variant (SM-G973U1) and the unbranded CSC (XAA)
Then using odin 3.13.3b flashed the rom

Hello, I'm in more or less same situation. When you flashed, which files did you use? All of them or just the AP_*** file?
Never mind. Flashed it anyway, now I don't see the AT&T startup screen anymore which is promising. Firmware version is now Android 11 (SM-G973U1 and not SM-G973U) on XAA CSC. Will see if I get any firmware updates later.
