How do you know that your phone is developer edition?...
That message might means that your FW is not from the country for what the phone was released.
I have a non branded european phone, if I flash the Indian version or the brazilian almost for sure I'll have the same message.
Try to recover it with LG Update Tool and you'll have the official version for the phone.

please tell us what version of firmware u have

On the back of my phone it shows " Not for Sale ". i got this phone from ebay.com. i think they sold me the phone of Developer Version. Thats why i just want to know how to convert that phone to " Consumer Edition". i did the same thing that the "Xavier" told on his thread but my phone turn off after 4 seconds when i connect it with usb by pressing and holding the Volume Up button...

all i know is that, is a code, a part of phone os that monitors and loads the os when phone starts. Unlocked bootloader means, custom roms can be installed like cyanogen mod, that boost up performance and it is a way to get latest android like jelly bean even though lg has not made one. Many saw a video running cyanogen mod on 4x but everyone told that it was a developer device. Only developer devices have unlocked boot. But we (even i) don't have unlocked bootloader. So, i think you should contact the developer currently working on it and ask if you can help him (if you want). He may get serious help from your device. Your can be precious if you really have an unlocked bootloader. So, keep it as that. If we get bootloader unlocked, we will smash galaxy s3 on benchmark. Our phone is beast but clamed down by locked bootloader by ******* lg.

For what I know, a dev phone is a big help if the firmware is v09x... V10C is useless, we have it too. From where can we take info about bootloader once the firmware was already updated??? Maybe thats why the message " Device not Registered yet ".
Just try to flash like everybody, using the "normal" flash methode.

Forget about your phone be a developer edition....
developer edition runs under v09x firmware, once that yours is already v10c (I think...) the transformation was done already.
Just use the normal methode to flash it.

I originally had a cwt branded phone but flashed the leaked v20a and was able to unlock my bootloader
Sent from my LG-P880 using xda app-developers app

I have too this phone but I'm using euro open v20a. I unlocked normally with leaked v20a and it stays unlocked with official one. So you can flash euro open and try to unlock with official procedure. Wish you luck. :good:

Hoping you guys will help me on this matter :fingers-crossed:

Thank you #gregbradley
Actually, I wanted to Flash Custom ROM on my Device but many article says: "Unlocking the boot loader allows you to put custom ROMs on your device" It is true ?
Regards,
Clasher_RS

It depends if the custom rom needs a custom kernel, some do, some don't
But in general, if you find the custom rom in the development section you only need root and not an unlocked bootloader, but if it is in the original development section then you need an unlocked bootloader as that rom requires a custom kernel.

Confused about bootloader unlock.

Noob question here. Can anyone tell me if I can unlock the bootloader of LMV405EBW that I bought in India?? The lg website states bootloader unlock allowed only for European version which is the same variant.

Despite Indian version having the same model name/number as European, you won't be able to unlock it officially - LG Developer site will detect the version by the serial number. You can unlock the BL via unofficial channel here https://remote-unlock-service.com/en. It is paid service though.

I have a US unlocked V40, model number V405QA. If I do this, does that mean I can root? Can you post some directions on how to root this phone once I unlock the bootloader?
Thanks!

All versions, except t-mobile, can be unlocked. I think one version, the UK ebw, could officially be unlocked, but not 100% certain. If you look in the 'Guides' thread, you'll find the guide to unlock the boot loader of any version but t-mo.
cheers

I don't understand your question, do u mean "can we' unlock etc? The security patch level has nothing to do with it (unlocking), so don't know why u even mention it? Can u unlock if it has 10? yes.
