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.

LG V40 (V405)

Dear all.
I have a LG v40 6GB/128GB. After a long time, I tried LineageOS, but now I have to go back to stock.
I don't have success with the tools.
After switching to the right DLL, I got a message like crossflash from 405EBW to 405 not possible.
Exactly: Error: 0x4, Not support cross model download V405EBW to V405.
I tried to flash:
V405EBW30e_00_OPEN_EU_DS_OP_0903.kdz with DLL 1.0.36.10 and LGUP1.14
Any idea?
Thanks so much.
