Hello everyone, I have an lg g4 h811 that constantly says please select a known model in LGUP. I want to return to stock firmware from AEX pie rom, and now I am stock in a boot loop. It gets into download mode though, I have tried all methods I know like using flash tool 2014, lgup, updated all the drivers, even changed the com port to 41 ( in case of flash tool ) still no luck. please I need help ASAP.
Did you find a solution for this? I am experiencing the same thing.
Hello .. I have a LG G4 811 t mobile 32GB phone, what is the appropriate flash?

I searched but could not find a solution that works for this particular issue. I have Verizon G2 flashed to the T-Mobile 30b Lollipop ROM (for Verizon G2). My phone currently shows a model number D801 (and not the original Verizon model). I am trying to revert to factory Verizon ROM and the LG flash tools gives a wrong model error when I try to flash the Verizon ROM. (I have tried two different DLLs with LG flash tools as suggested in the LG flash tools thread but neither worked. I am assuming that this is DLL issue. If anyone has successfully reverted from T-Mobile 30b Lollipop ROM to Verizon stock, could you please outline the method. Thanks.
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.
are you telling me that software info in about the phone is wrong

Same here but purchased via Amazon UK..
I'm interested in crossflashing LG V40. I did that on LG V30+ twice. Here is the XDA topic: https://forum.xda-developers.com/lg-v30/how-to/using-lgup-crossflashing-t3780969
My YouTube Tutorial:
I had LG V30+ (us998) on Sprint and all the bloatwares. I used patched LGUP & DLL file and flash ls998 witch is unlocked V30 kdz. Ot worked prefect. Then i tried to flash some another kdz file, didn't succeed, brick the phone. But then i use CHIP erase and tried to flash ls998 (unlocked) on it. And it worked but that delete serial number and other details. Bc i did chip erase. But phone worked fine at the end?
can the lg g6 h872 be flash to lg g6 h873 original firmware android 9 .. t mobile just takes millions years to update ..or can be flash to verizon variant? and if not whats the worse can happen softbrick? thank you in advance
unfortunately no, I tried to flash H870 fw to unsecured partitions such as system, boot, and persist didn't work. i'm prety sure those 3 partition aren't secured by ARB so you can try by yourself with custom flashable zip and flash using TWRP. You can't flash trough LGUP since the rest of LG G6 firmware are still ARB00, it will refuse any G6 kdz except ARB01
does android 9 on lg h873 ARB01?

i don't know, If you want to try then go for it. flashing system, boot, and persist are safe as far I know, the rest partition might be protected RSA things

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.
