@blu3m3,
when it asks to press volume up, just press it and in a few seconds bootloader will get unlocked
But don't forget to type the command 'fastboot format userdata ' & hot enter after unlocking bootloader.
And one more thing, just don't worry about that OEM unlock option in dev settings, it does nothing

That's what i do too,
I enabled in Developer Options OEM unlocking
I done what you told me , but still not working
I pressed up and waited about 2 minutes pressed.
I think bootloader must be locked something else, but i don't know how.

check if your phone's drivers are installed correctly and whether your phones is recognised in fastboot mode or not.
you can check it by typing "fastboot devices" and enter.
If it shows something like device serial name or anything, then your device is connected in fastboot mode otherwise install correct drivers.
Hope this helps.

wait! wait!, if you wanna flash a ROM after unlocking bootloader, then you can do that without unlocking it too. Follow the steps.
1). Download flashable twrp zip by 1cefire and put it in your sdcard and also extract recovery.IMG from it.
2). Put that recovery image into the folder where you have your fastboot and adb files.
3). Reboot to fastboot and type
"fastboot boot recovery.img"
after that phone will temporarily boot into TWRP. Now just flash the flashable zip of TWRP from yr sdcard to permanently install TWRP recovery.
Hurray, now you can flash any ROM without unlocking bootloader.
Press thanks if it helps.

them you should try flashing the same recovery.img with SP FLASH TOOL. Just replace stock recovery with this one and uncheck all other options except recovery while downloading through SPFT.

Nobody has anything new to unlock the bootloader ?

Hello friends,
I'm have made a "Flashing guide" to update your Blackview BV6000's ROM to Nougat 7.0.
Please follow the link below and update ROM. You could also find a "TWRP installation + Rooting Guide" for your Blackview BV6000 in the archives.
http://dreamworks75.blogspot.in/2017/08/rom-flashing-guide-blackview-bv6000.html
Happy Flashing !!

+1 on this one.
I'm too stuck on that disabled volume up button, when confirming whether to oem unlock the phone.
I've read in a blog post (can't link yet) that one can specify a 16-digit unlock code for the fastboot oem unlock command, but I have no idea whether it would allow me to confirm unlocking - and also no clue where that code could be obtained from in the first place.
So, any further info?

Can't access full fastboot commands

Hi all, I was wondering if you know, after bootloader unlocking, why I can't access full fastboot commands as the one to remotely boot a recovery. "fastboot boot recovery.img" says "Failed: Command not allowed" and also does "fastboot oem ?" to list oem commands. OEM unlocking is permanently On , on the Dev Options and as I said before, bootloader is unlocked. But, I still can, I guess, flash boot, recovery etc. but I don't want to do it right now. I can tell it because so happened on my previous Huawei Phone and what's happening now on my P10 is the same thing. Thanks in advance.

Up, my ROM is VTR-L09C55B130 stock and I'm on Android 7.0

Unlock OEM via ADB

Hi, so my Xiaomi MI A2 is kinda not working and I think that wiping cache partition might help but I can't access the recovery so I wanted to install TWRP. The thing is I have the boatloader locked, I have the USB depuration activated but not the OEM, so how can I unlock boatload or unlock OEM via fastboot?
Thanks

Flashing Unlock
Hey, make sure that you have first unlocked the bootloader with the fastboot command: "fastboot flashing unlock". Try it. It will erase all your data and do a reset factory and then you should be able to reboot your device normally. Also, it will let you flash the boot.img for root your device.

Did you let unlock bootloader and permitted the USB debbugin on the developers option before flash the boot.img?
Make sure you are using a USB 2.0 to connect your device to the PC. See if you PC recognizes the device into the fastboot menu with "fastboot devices", if doesn't, try reboot another phone with "adb rebbot bootloader", then enter "fastboot devices", your device should be listed into de the devices attached. Then try again entering "fastboot flashing unlock".

Oh, that could be a problem. Try to use this tool. I hope you can get your phone working again. If this doesn't works, try to flash the original boot.img of your firmware version.

Relock the Bootloader?

I know asking this question at a very early point would be very foolish, I tried searching various places for the answer but didn't, can anyone from previous experience or with answer tell me how can the Bootloader be locked again?
Thanks in advance!
EDIT: Thanks to IDunnoLookatXDA The BL can be locked using
Code:
fastboot oem asus-lock

Holy SH1T that actually worked
for beginners oem is no command
To lock the bootloader (or remove the annoying prompt you get at startup)
Code:
fastboot oem asus-lock

FAILED (remote: Command not supported in default implementation)
finished. total time: 0.004s
Please help

I've sent the device back because of Display issues, and no longer own it.
But what I understood from your response and suggest you is:
Turn off the device and put it in fastboot mode, then issue the above command and it should work. Hope it helps
