LG G4 MODEL H815 but can't unlock bootloader!!

Hi guys I have an H815 brand "tim(an'italian carrier) 2 hours ago I was trying to unlock my bootloader and when i wrote the imei it said "your device does not support unlocking the bootloader"
So the question is.. WHAT'S THE PROBLEM?
The problem is ; your device is not supported...
In other words the tools and guides on the official lg developers site aren't compatible with your version of the phone.
It is probably because you seem to have a carrier branded H815, and that carrier does not allow to unlock the bootloader.
You'll have to wait for LG to support your phone, LG has released a statement saying it will slowly add more devices for unlocking the boatloader

so basically there's no way to get rooted marshmallow at this point without unlocked bootloader

seems like you may have the G4 that cant be unlocked.. so thers no way.... you could root and install xposed but on LP only... with locked bootloader.. only a few h815 from some countries can be unlocked..

Root h815 with locked bootloader?

Hi.
I have just purchased a used h815 and when I went to unlock via the official lg website, I was informed that my phone was a US variant, and unlock was not available.
I'm currently running 20h.. is there any way at all given the locked bootloader to
A) get root access?
B) install cm13?
If the answer is no.. i think I'll be sticking this back on eBay...
Thanks!

Bootloder unlock

How can I bootloder unlock my lg g4 "TWN"
my phone does not support bootloder unlock
so what can I do?
You can wait or do some research and write a bootloader unlock tool for everyone
...we are all waiting :/
You would probably be waiting indefinitely. It does not look like there will ever be a bootloader unlock for the G4's which are locked.

you can root yours if it is dual sim model . Forget unlocked bootloader .
My H818P is rooted with Lollipop.
But to Be honest, I'd rather have an unlocked bootloader :/
No root on MM and up is a pain.

You can still root...I have h815 twn model, running 5.1 rooted...if you are on MM you need to use LGUP tool to downgrade to LP and then flash the rooted fw with flashfire...there are YouTube vids on it, just search

Thanks, @patilkalpesh for the screenshot.
F500L is written on my phone motherboard.
See attached image.
Currently, I am using F500L30b (nougat) version.
I can't boot into bootloader, the phone just restarts if I try to boot into bootloader (fastboot) mode. Please please solve this problem so that I can unlock the BL.

Then I will try this method but not today (After reading WARNING on that thread, I am little bit afraid)
@steadfasterX
Can you tell me, why all USSD codes are not working?
for example: If I type *#06# then nothing happen or if I try any other ussd code then also nothing happen.
Is there any solution for it?

Yes dude being afraid makes totally sense and is for a good reason.
The risk is high, you can loose a lot or win a lot. Up to you..

Those codes are ROM dependent and you're using a brand new version (nougat for your device is just a few weeks old)
Maybe try
*#*#06#*#*
##06##

Can you check your anti rollback please? I don't know if the f500 has it implemented but that could be the reason.

thats very good (and so not the issue)
try to use an USB 2.0 port if u currently using a 3.0 one.. sounds still strange to me but I saw that error related to the usb port somewhere.
Besides that it could be likely a wrong msm DLL issue or you're just following the wrong guide.
I think this one should work for you too:
https://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
otherwise do a search on this error like here: https://forum.xda-developers.com/search/thread/3107848?query=0x2000
I would recommend better asking in the above thread for further help is better than going on in this thread here (has nothing to do with your original question btw... )
