LG V40 - T-Mobile LGUP kdz update safe? - LG V40 Questions & Answers

Currently have a T-Mobile (LM405TA) that's stuck in an update. Haven't been able to figure out a workaround.
Current OS: Android 9 - T-Mobile 20h
Preferred OS: Android 10 - T-Mobile 30e
Are these T-Mobile devices safe to use LGUP on to flash their own KDZ file?

Yes that's what the kdz is for, to update the phone. But if your phone, as you say, is stuck in an OTA update, LGUP may not recognize the device, have you verified you can get to download mode?
If so, I'd say go ahead and do the update.
cheers

Please help me with Lg g4 Ls991zv6 - H81520g

I bought a new Lg g4 model h81520g as shown in setting>about phone>software info. I wanted to check for update but there's no software update option, only apps update is available. so what I decided to do is to reflash the stock software to enable update option. I downloaded the kdz file "H81520g" but when I connected it to computer and ran the LGUP it shows another variant which is LS991zv6. I tried to flash the downloaded file, but it gives an error "invalid kdz. My Lg g4 comes with marshmallow on board. the stock recovery works fine, and also the download mode is fine.
my question is: should I download and flash LS991zv6? by the way, I checked my imei in imei info .com and it shows the model as LS991 sprint

Zv6 is lolipop no mm. U need to check the motherboard. Must disasmble the device and see what it says. Bit if the device is working i would leave it be. Its almost more hassle than its worth

Thats what im telling u zv6 is a lolipop firmware for sure no debate there..
Thats why i say leave it be. This is one of those if u mess up u can hard brick it. Theres not a diffrence between mm and lolipop motherboards but zv6 is a lolipop firmware. Not mm.

Stock firmware with unlocked Sprint version

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.

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..

hello thank for answer , can you give me tutorial to do cross flashing?
ok first download and instal LGUP_Dev_Frame_Ver_1_15_0_6, after instal usb driver LGMobileDriver_WHQL_Ver_4.2.0
in disc C\program filles find lg electronics\LGUP\model here make a new folder with the name (common) and in this folder common copy dll file- https://www.mylgphones.com/lgup-dll-for-lg-v40-thinq-version1-9-39-7.html this dll(LGUP_DLL_for_V40.zip)
now put the phone in download mode with usb to the pc
open powershell from the LGUP folder and type cmd enter
now indicate the address to the kdz file folder on your PC, in my case it was (lgup_cmd.exe com3 "C:\Program Files\LG Electronics\LGUP\model\common\LGUP_Common.dll" "D:\Zona Downloads\lg v40\V405EBW20d_00_OPEN_EU_DS_OP_1106.kdz)
if you have correctly indicated the address to the kdz file, firmware update will start
wait up to 100%
my phone
I believe I tried this days ago. However, after days of trying, I reread this, and it is clear to me that there are two problems with these instructions: 1. Firstly so many other threads say use only 1.16 and above for this phone. 2. you don't offer a patched link. The standard dev requires special passwords and doesn't offer a way to register.
I haven't found a dev version above 1.14 that was patched. Someone offered a patched 1.15 that supposed to help. But non of the dlls work, which I suspect is because no lgup can work with lg v405ua, below a patched 1.16 dev. I don't think I have found that unicorn yet.

Need AT&T Pie KDZ

Hello
I cross flashed US Unlocked kdz on my AT&T LG V40. I want to go back to AT&T rom. Can anyone share the AT&T kdz please?

Unfortunately, it doesn't exist. No one has one. There is another Thread about partition backups, and qfil was used to back up one of the AT&T kdz. But to restore is more complicated than just using LG up and a kdz.
Thanks for the reply. I think US unlocked might take it’s sweet time to get Android 10.
Anyway do you know if crossflashing stops OTAs. I’m pretty sure US unlocked has January security update but I’m stuck on November. When I try to search it says no updates available

Crossflash to 10, Error: 0x6004 Open_US>VZW_US

I can't get past an error when trying to crossflash my V405UA20a to Android 10 using the Verizon KDZ. The phone I have I believe is originally Verizon but was unlocked and flashed to something else before I bought it on ebay. I want to flash it because this phone does not get any OTA updates including security updates at all. Now when I try to flash it to Android 10 this error pops up (Error: 0x6004, CrossDL, OPEN_US>VZW_US) no matter if I upgrade or refurb in LGUP. I'm following the guides here and some have mentioned this error but I have not found a solution.
LG up v1.16.03
DLL v1.9.39.7
Any suggestions would be very helpful.
