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.

Trouble updating Galaxy Note 9

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

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

LG V40 - T-Mobile LGUP kdz update safe?

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
