[LG V40 Questions & Answers] awireless:
thats what we were trying to figure out but i guess only 1 guy knows and hes not willing to share so doesn't seem like will be able to do it and it doesn't unlock it anyway plus im pretty sure it wont be able to unlock boot loader either
[LG V40 Questions & Answers] strk3r:
If you think that you smarter than others, why you still dont flashed your v40? ;)

We tried bunch of methods to unlock - crossflashing with v405QA fw, editing NV items, restoring EFS, editing modemst.bins and other.

Now sim lock is gone, but network lock still here.
[LG V40 Questions & Answers] awireless:
I dont think im smarter then other idk where that came from im just saying there is no soultion yet and im correct right?
[LG V40 Questions & Answers] fredtre:
any new? I have a v40 sprint in my hands and I can not find unlocking method.
[LG V40 Questions & Answers] tobasamuels:
It would seem someone on E-bay has found a way to unlock Sprint v40s.

This here is the link

https://www.ebay.com/itm/LG-Sprint-...891248?hash=item4b62aa8bb0:g:cfIAAOSw8fpcs497
[LG V40 Questions & Answers] awireless:
If someone buys this service you should monitor the phone very closely and tell us all the steps that go on and how long it takes so we can reverse it and try to replicate it.
[LG V40 Questions & Answers] fredtre:
I just sent a message, hopefully have the solution.
[LG V40 Questions & Answers] tobasamuels:
I hope you get a solution as well. Please update us as you go along and about any problem you encounter.

To also buttress [MENTION=9079296]awireless[/MENTION]'s point, maybe use a screen recorder to get the steps
[LG V40 Questions & Answers] Pauliecoon:
If you go through with it, you'll need to run something to sniff USB traffic throughout the process, Wireshark or something similar. You'll need to start it before you start giving him access, because after he has access you won't be able to. Also consider hiding the sniffer, or at least making it not obvious (minimize to tray, hiding the tray icon, rename the executable etc.) These people don't want anyone knowing what they're doing, once that happens their service is obsolete. We really need someone to do this with the Chinese remote bootloader unlock people as well.
[LG V40 Questions & Answers] awireless:
I agree and it will also tell us if there using a custom solution or if there using some sort of box like z3x or octopus because those will block wireshark with usbcap on most operations so if the process fails its most likely a third party tool.
[LG V40 Questions & Answers] ShiningRaven:
This website claims to support the V40. When you put in your phone information and IMEI it redirects you to their remote unlock page. The service costs like $50. I want to do it and try to capture their method if possible. But I really don't know exactly how to do it without them being able to tell.

Here's the link: https://www.cellunlocker.net/unlock-lg/
[LG V40 Questions & Answers] awireless:
Dont do it all those websites just copy paste older listings and change the model number and some info they wont actually be able to do it this is one of those websites that say they can unlock a device but then say they cant dont waste your time on these guys.

If you still want to then install wire shark and usbpcap(Can install it when you go through wire shark install) then click the usbpcap button with the line showing the data and check the box that says something like record only newly connected devices and start then connect phone you will see data on it then minimize it and give them teamviewer should work. If your confused i just google it when i first learned it its simple.
[LG V40 Questions & Answers] ShiningRaven:
Thanks, I figured it was probably bogus. But I guess I should just confirm that they will either not charge me or refund me if they can't deal with that model and then go for it. Mostly I just didn't really know what program to use to monitor the connection. Now that you gave me that it should be easy. I'll try it later and let y'all know what happens.
[LG V40 Questions & Answers] garceran:
I talked with them. Not supported.
[LG V40 Questions & Answers] ShiningRaven:
Oh well, it was worth a shot. I also talked to the people from the eBay link above. They told me that the unlock process for the V40 is under development and is not available at this time. So there goes those two ideas.
[LG V40 Questions & Answers] fredtre:
I was in contact with the guys on ebay, they mentioned that they were doing tests with that model and that at the moment they did not have the solution but they are working on it.

Another boy who makes unlocks from ebay for LG models (G7, v30, etc) mentioned that he had a theory. I guess he tries to do crossflashing and said he had to download a VZW KDZ.

I have not done it because I guess I'll get brick Phone.
[LG V40 Questions & Answers] awireless:
You wont brick your device if you try to flash Verizon nothing happens i already tried and also only cross flashing wont unlock it anymore even after cross flashing the device will still be locked to sprint
[LG V40 Questions & Answers] ShiningRaven:
Just curious, if you could manage to cross flash it could you then "repair" the IMEI to make the network think it was a VZW phone? Or is it still locked inside the modem?
[LG V40 Questions & Answers] awireless:
Well the imei is fine after cross flashing from what ive heard dont need to change imei in any way. I believe why the other lg phones get unlocked like g7 and v30 after cross flashing is either the partition that is locking the sim is being overwritten or the firmware is just completely bypassing the lock so its still there but is not checking for it so the v40 might have a different partition layout or always checking the correct sim lock items. someone already tried editing nv items and efs system they said it wont work my idea is we need someone who knows qualcomm protocols and use DM communication to force a uicc unlock just like samsungs s9,s9+ is being done.
[LG V40 Questions & Answers] barselonec:

[LG V40 Questions & Answers] TheDunkan:
Any news? Thanks a lot :)
[LG V40 Questions & Answers] patato21:
On my Verizon V30 VS996, I was having issues with LTE band 12 since the VWZ modem and fw doesn't enable it by default. I had to request someone with a V30 US998 to make a dump of their modem, modemst1, and modemst2 paritions then I flashed them. This brought me all US998 LTE bands including Band 12. I also realized that after doing KDZ "partition dl" with Nougat US998, then Oreo US998, I was not getting Band 12 again on a different phone until I used "refurbish".

Maybe here on the LG V40 we need someone with a USA Unlocked V405QA7 to make a partition dump of modem, modemst1, and modemst2 and then flash those onto a converted Sprint V405UA. There is already root for the LG G7 here: https://xdaforums.com/lg-g7-thinq/how-to/to-unlock-bootloader-root-models-t3928505 It should work on the V40 since the bootloader unlock method is based on the LG V35, and the V35, G7, and V40 all have the snapdragon 845 chip.

Also, verify that those here who have a converted Sprint V405UA that you are running V405QA7 firmware. There is V405UA firmware but some appears to be for Telcel Mexico, and Verizon.

If you want to try to bootloader unlock your LG V40, message motogvasyag, he is doing the unlock for free. He flashes the V35 engineering bootloader and you can then flash TWRP. The engineering bootloader is the "abl" partition that can only be flashed through an Octoplus box but can be done remotely. This was an obscure method found on some Chinese websites like Baidu and Taobao, but now it is clearly known and very easy! Once someone unlocks it, we can proceed to flashing the V405QA7 modem, modemst1, and modemst2 simply via any adb root shell or TWRP.

I also found some patched LGUP on the G7 forum, maybe someone can try and flash the V405QA7 KDZ via "partition dl" with one of these 3 versions:

[LG V40 Questions & Answers] awireless:
How do you get a v35 enginering bootloader and how to flash it all LGUP wont work to flash patched or not.
[LG V40 Questions & Answers] patato21:
I forgot to mention earlier that the V35 engineering bootloader is found somewhere in this thread (look through it). It came from a developer/special factory copy of a V35 most likely. It is useless because it can only be flashed with an Octoplus box, but someone with such box can do it remotely for you. Message motogvasyag for a free appointment.
[LG V40 Questions & Answers] awireless:
It says v20 on the link you provided is that correct?

How to flash with octoplus this is zip file and octoplus only can flash .KDZ .TOT and .OCT files
[LG V40 Questions & Answers] patato21:
Yes but that is the way androidfilehost indexed that file. The thread it came from is talking about V35 bl unlocking, same purposes for us G7 and V40 people.

Also I think the Octoplus box can let you flash any partition individually. Do you have one? The zip file contains the abl_a and abl_b partitions and are identical, this is just LG's new partition format for Project Treble.
[LG V40 Questions & Answers] motogvasyag:
Unlock via OCTOPLUS JTAG looks like this

https://www.youtube.com/watch?v=p8Z0KOUNw7Q&t=21s

I did it on the LG G7, on the LG V40, the same way!
[LG V40 Questions & Answers] awireless:
Yes i have it and i also message the guy doing it and he said he using octoplus jtag i havent used the jtag software so need to figure it out first. Octoplus lg cant flash individual partitions unless its in the format of a kdz tot or oct so im guessing the jtag is the only way.
[LG V40 Questions & Answers] lolwatpear:
patato, can you upload your V30 modem zip?
[LG V40 Questions & Answers] Tonykirks57:
Im folowing this thread pretty close. Im hoping you guys get it done. I have a sprint v40 im looking to use on att. You guys are my only hope! Keep up the good work.
[LG V40 Questions & Answers] patato21:
Sorry for the late reply. What do you need it for? I now only run the H933 (Canada) firmware KDZ because I was having LTE issues on my AT&T MVNO carrier on US998 firmware.
[LG V40 Questions & Answers] zeek6228:
can anyone share the link for this engineering rom srf file? I have octopus jtag box
[LG V40 Questions & Answers] lolwatpear:
I wanted to see if it would stop my lte issues (I have the same phone and att like you) issues, however I reflashed the us998 modem and I appear to be getting all bands now. I am running lineageos though, so I don't know if it's different than running stock. Why isn't the us998 modem alone working fine for you if it looks ok for me? I appear to be receiving all lte bands.
[LG V40 Questions & Answers] patato21:
Like I said earlier, my phone is a converted Verizon VS996. AT&T deliberately whitelists only AT&T branded devices for use on their LTE network. I was getting 3G all the time even though on T-Mobile I had good LTE. This issue has happened on many unlocked phones throughout the years.

Octoplus jtag pro use the .srf to flash the bootloaders letting you unlock root install other roms etc. I have done many it works
[LG V40 Questions & Answers] e46_nexus:
I found the srf, do I just put it in download mode?
[LG V40 Questions & Answers] awireless:
No, you need to be in qualcomm 9008 mode make sure drivers are installed and plug phone into computer while phone is off and imedantaly hold volume + volume - and power quickly pressing volume up button there is video on youtube on how to do it its tricky. Then on jtag software click on welcome tab click install custom firmware use the .srf select the lg and press connect then go to smart repair and repair the two partions when it says disconnected unlpug and hold power volume down until phone reboots. Sorry for poor instructions have to write quick.

---------- Post added at 04:37 PM ---------- Previous post was at 04:26 PM ----------

We need someone who makes those emmc recovery files for the Samsung phones and someone who can deconstruct .srf files then we can make a file that everyone can use no need for octoplus box but need to be in contact with people who can do those two things.
[LG V40 Questions & Answers] zeek6228:
SIM unlock

OK so if I open the device, put it in QC9008 mode with test points, flash this *.srf loader file with Octopus JTAG, then will I be able to do things like repair IMEI, SIM unlock?

I have been following this thread (SIM unlock Sprint V40) for a few months but it seems we are talking about bootloader unlock.
[LG V40 Questions & Answers] awireless:
if your able to figure out sim unlock and repair imei let me know because no one can do that right now. just frp remove and unlock bootloader and fix bricked devices thats all we can do with these .srf

also no need to do test point you can use button combo to get into 9008 mode

---------- Post added at 11:33 PM ---------- Previous post was at 11:30 PM ----------

maybe you can extract carrier partition from unlocked phone and write it to a locked phone that might work gotta figure out how to do that tho
[LG V40 Questions & Answers] zeek6228:
I've tried reading and writing different partitions with jtag tool, if modemst1/st2 doesn't match the IMEI is 0. You can't read backup from one file to another.

Testpoint easy, just use tweezer =)
[LG V40 Questions & Answers] Ainz_Ooal_Gown:
Well the problem is Sprint Never leaks their KDZ...
[LG V40 Questions & Answers] awireless:
When imei is 0000000000 is phone unlocked though? Because if it is maybe we can patch the partition with imei + unlock data
[LG V40 Questions & Answers] awireless:
If anyone wants to try they can read carrier partition info from a uicc unlocked sprint v40 then write that to a non unlocked device and see if that works thats how alot of the other sprint lg got unlocked when there is no other solution. May break your device but let us know if you try it.

i have full dump from unlocked via OTA Sprint phone. Trying do all.

flash all partitions - imei 000000

restore modemst1/2,fsg - phone locked

flash just carrier part - phone locked

I have some idea, but dont have v40 in hands
[LG V40 Questions & Answers] awireless:
You can try to isolate where the uicc information is stored so we know what we need to flash.

Use a hex editor to see if you can find any mention of uicc in the partitions you dumped

also dump partitions from a not unlocked v40 on the same firmware version and compare the hex data see any differences.

Dont edit the hex and reflash it tho that will cause corruption. Its just to see what partition has the uicc data in it.

It will take a long time going through all the data i dont have enough time to do it but i think either we can flash uicc unlock to one thats not unlocked or find the trigger for it and use that to cause the unlock to happen "Officially".

Since there is also root for this phone you can search through the partitions of the phone through adb which might be easier then searching through hex to find it and just find where uicc is stored.

Phone showing a message after each restarting like a "registering for the network". After 5-7 mins message "failed" comes up with the "ok" button. And it's working fine afterwards till next restart. Now I'am using Vodafone SIM at the other side of the planet and all fine.
