Hi again to everyone! I still have my very best LG g4 LS991 and few days ago I received OTA UPDATE. Now I have ZVI software and phone is relocked. Can somebody, please, tell me any solution for unlock it again? Old solution don't work.

It does suck.. that you have to pay for updates because sprint wants to be ignorant....
I understand people selling phones that are subsidized and not paid for...Ok black list them properly world wide not just from there network.. But block methods to unlock the device when if you are not a sprint customer they will not unlock it for you either. Thus making the device unusable either way.....
Kinda of a shady move in there part as sprint Lgs in the past few years have been really easy to unlock free rooted methods.
Then people are now going to such extreme I will try anything lengths to just get it unlocked They are bricking the device. Thus in third leaving the device completely unusable.

Check if your LG is not hard locked and you still have a few unlock attempts left.

It is sprint model. What you talking about? I unlocked it before with software method.

Hi again to all. I already unlocked my phone with remote unlock service, but I can't switch to mobile internet (it is E/H+ network I use). First time after service man unlocked it for me it was impossible edit APN settings. I asked him for help and he changed settings of system files, so I can edit and save APN. Please tell me any solution. I think maybe I must write some APN type or something else. It is look like I need just one little push to direction.

Yes, but LG changed Acces to Hidden menu, so you can't already use this method on latest versions of firmware.

LG V40 DLL Ver. 1.9.39.
Yes, we can run & open LGUP 1.14 with this DLL, and detect the LG V40, but we still can not upgrade/refurbish
LG says LGUP 1.16 is needed..
when I patched the DLL, LGUP says, The DLL is invalid.
so anyone wants to try the LG V40 DLL, please leave me a message.
Here is the LGUP DLL for LG V40
https://www.mylgphones.com/lgup-dll-for-lg-v40-thinq-version1-9-39-7.html

LGUP_Cmd.exe is from LG official, It is not patched.
Usage 1 : LGUP_Cmd.exe [COM Port Number] [DLL_PATH(Optional)] [SW_PATH] [EXTRA_OPTION(Optional)]
Usage 2 : LGUP_Cmd.exe LGUP_GET_INFO
The best way is put stock kdz firmware in the folder 'C:\Program Files (x86)\LG Electronics\LGUP"
Use: LGup_comd.exe as administrator
LGup_cmd.exe com3 XXX.kdz

Just for future reference SIM lock on LG SD845 is build now with strict hardware dependencies based on Chip ID and signature. The only way of removing SIM lock so far, apart from using official operator SIM unlock methods is to re-solder chip from already unlocked SD845 device and refurbish the phone - so all those well known tricks of erasing some files cross flashing different roms etc. is not working any more. Just save your time and efforts...

Aw man that's awesome! So did it work? Did u succeed or not? Please tell us more.
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?

I'm assuming he either has access to the latest LGUP (1.16) that supports the V40 along with the .msi/DLLs needed, or has access to LG Flash Tool with the hard to find V40 DLL for the flash tool.
Either way, instructions aren't going to get posted from what I can see.
That's awesome though, have fun with that!

Where are you obtaining these "strict hardware dependencies" claims for the SD845 chips? From what I've seen, the G7 and V35 phones that are crossflashed in LGUP end up being SIM unlocked just like on the old V30 phones. Those are also SD845 so the "Chip ID" lock would not make sense. I believe the old modem data is STILL stored on the modemst1 and modemst2 partitions on the V40 with the Octoplus flash method because the only way they are being crossflashed at the moment is through Octoplus box, and the G7 and V35 are being crossflashed with just LGUP. It seems LGUP's REFURBISH mode clears this old modem data when crossflashing, as I have had similar SIM lock or no signal issues on the old V30 that were only fixed after using REFURBISH or flashing appropriate modemst1/2 partitions.

LM-405EBW ( TIM firmware) LG Bridge problem

Hi everybody!
I've tried to update my LG V40 over LG bridge. Bridge recognize my phone and finds new software V405EBW20e_00_TIM_IT_DS_OP_0210, from 20th march. But after downloading it it keeps crashing after entering firmware update mode. I live in Serbia so I presume OTA updates are not available for me. Is there a way to flash it with unbranded european firmware, and will that enable OTA updates or updates over LG Bridge? Thanks!

Something must be delayed somewhere, because I just got an update this month.

Greetings to everyone!
I am writing from Hungary and I have a V405EBW TIM region coded (service provider) phone with a closed bootloader and no root. When I bought it, it was probably handed over with V20d HUN Pie ROM and I was able to upgrade to V20f using LGUP (I didn’t upgrade to V20g because I was expecting Android 10). In the Hungarian forum, which I read, they upgraded to Android 10 with LGUP also a TIM service phone. For this, a DEC region ROM has also been uploaded with LGUP without any problems. After upgrading to 10, the following error message appears when you turn it on: "Current version is not available for user. Can't find matched carrier. Check NT-code: 2201: FF". My questions are: can I somehow upgrade to 10 so that there is no error message and the serial or IMEI does not disappear (see YouTube "Install Android 10 LG V40 / Actualizar LG V40 Android 10" first post) or pass can NT code be written to an independent European model without root without any problems?

I've found that if I do a crossflash, then, don't make any changes to the device, shut it off, then do a refurbish with lgup using the same rom as the (part DL) crossflash, the 'NT Code' problem will go away.
cheers
