Issues unlocking LG G4 H815

All,
I'm having issues unlocking my H815 LG G4. I enter the proper IMEI and device information into the location on LG's developer website to unlock it but then I get an error which I have attached.
This has been discussed many times before.
You need a region specific H815 in order to unlock your bootloader. A specific EU variant is the only one that LG supports unlocking right now. My Taiwanese specific G4 is not supported. If you'd like, you can msg LG and pile on the requests to unlock all H815 variants, but I believe they said they wouldn't.
Good luck!

Any Ideas on how to root without bootloader unlocked?
Im having the same issue the only difference is that my LG G4 h815 is the EU open market variant which is the one that can only unlock bootloader im getting the message saying everything is correct but cannot unlock bootloader, i contacted lg support dev, the answer from them is that i cannot unlock my G4, this is bull**** i pay i want full control of my phone. hope someone can come up with a way to root this device without unlocking the bootloader just like with the G3 model.
Returned mine and bought another straight from a site in the UK. Went without a hitch.

Trying to unlock bootloader if phone not European?

I've bought a used G4 from someone who is "pretty sure" (but not 100% certain) that it's a European model, as it was purchased from a seller on Amazon shortly before the phone was released in the UK.
I want to root the phone, so my question is: if I try to unlock the bootloader using the official LG method, but the phone turns out NOT to be a European model, am I likely to brick the phone?
No, if it cannot be unlocked, lg simply won't give you the unlock.bin file for your phone. So just try to get this file from lg and see...
Thanks. I just tried requesting an LG unlock code and it seems I'm out of luck as I seem to have a Taiwan model :0(
I guess there's no sign of a bootloader unlock for Taiwan H815's yet?
Am kind of frustrated ? i need to unlock the bootloader and i can't, that's the reason i bought lg h815 eu and it cannot unlock bootloader please someone help

LG G4 Marshmallow Root w/ out unlocked Bootloader

So I was finding my my Device-ID and IMEI so I could unlock the bootloader, but LG'S website said Singapore models weren't supported. My model is the H815. So knowing this is there any way to root my LG G4 running Marshmallow without unlocking the boot loader? Or if there's anyway to unlock the bootloader for Singapore models.

H791 unlock

Does anyone know if all H791 model phones are factory bootloader/OEM unlocked?
I just ordered mine from a vendor here in Japan and it is H791 which works with all cariers so I'm guessing it's OK but I'm a little worried if the bootloader will screw me. Model is H791
The bootloader is LOCKED. You can unlock it by following Googl's instructions here. You should NOT re-lock your bootloader while running any custom stuff. Only re-lock your bootloader after you've flashed a factory image.
So carriers do not lock these phones permanently like Sony? Good news

Question - factory unlocked H815- will oem bootloader unock etc affect carrier unlock

Simple question but can't really find the answer online.
Bought an H815, no carrier label etc. My ATT sim works in it.
I want to unlock the bootloader (OEM process) root, add TWRP and flash custom ROMS. Will this affect the factory unlocked carrier status?
How is it carrier unlocked btw , at the hardware level or bios type process? I see the H815 comes factory carrier unlocked?

Assuming your phone was purchased sim free, then no, bootloader unlock shouldn't affect it. You can always make a backup with SALT first (bootloader can be locked when you take the backup) so if for whatever reason it does get removed then you can restore it.
Btw, LG's don't support fastboot oem unlock. You need to do it via Official LG bootloader unlock website or UsU (look here in the threads) if your device isn't supported officially - if it is an EU H815 it official should work though.
fr eBay sim free. I'll look into the SALT backup.
I did a bit of work already and signed up as an LG dev and do see the LG website process which I was going to do to start.
So then adding TWRP and a custom rom will not affected the carrier unlock as well?
thanks
