I had the exact same issue as you, but in the above method TWRP would not flash properly onto my 1+2.
So if the above doesn't method doesn't work, try @Lord Boeffla modified recovery tool which will load Stock Recovery for you.

Hello.
Long story short:
I have a OnePlus2, I can boot in Fastboot mode and my PC does recignize the fastboot device.
fastboot oem device-info says that Bootloader is locked and when I try to unlock (fastboot oem unlock) it states "okay" but cannot boot into system because there is none installed. -> Bootloop
I cannot boot into recovery nor install a recovery due to the locked bootloader.
My Question:
Is there a way to unlock the bootloader in fastboot and/or install a boot.img?
I am happy for any help that I get.
Have a good day/night

No, but why you don't have system?
You have stock recovery download official signed full zip and flash it. Recovery.
Also unbrick guide using the one you need Qualcomm drivers

Hi all,
I've unlocked my A2017 Chinese bootloader,
Installed TWRP and B29 base rom.
Everything worked great until I made a mistake and relocked the bootloader.
Now the phone just showing the ZTE blue logo and turn off.
I can boot to the bootloader with holding both volume up+down but when I try to oem unlock it i get:
FAILED (remote: oem unlock is not allowed)
The system is not booting so I can't allow oem unlock from developer menu.
What can I do?
Thank you in advance.

Hi, you need to flash the bootloader accepted recovery.img first. Download the latest B13 chinese official rom and extract recover.img. Use the command to flash it:
fastboot flash recovery recovery.img
Then reboot to this official recovery, and flash the B13 official rom. Now you can restart your previous bootloader unlocking process( actually I have no idea of how you succeed on the A2017 model). Good luck!
----second thought:
I doubt if you can successfully execute the command
fastboot flash recovery recovery.img
since your bootloader is locked. Just wish you good luck!
I normally receive my phone in few minutes, for unlock bootloader, i must activate debugging and reboot bootloader and fastboot oem unlock? When twrp is available just fastboot flash recovery twrp.img?

In developer settings I believe there is a second toggle you need as well. Something like Unlock OEM bootloader. Select that and then you will be able to use the fastboot command.

yes i see it and unlock my bootloader with command line
Hi everyone,
I am the owner of an A2017G, unlocked bootloader.
I tried them all, but all of them and I can't get into fastboot / bootloader mode.
Ihave flash rom via MIFLASH and AXON7 EDL TOOL using rom Nougat and Oreo, but the result is always the same !!!
Do you have any ideas to help me, perpetuate?
Thank you.
Use miflash and flash unlock bootloader image by Turkdev, even in oreo it will give you fastboot menu.
I did this 3 days ago to relock my bootloader
Use this tutorial:
https://forum.xda-developers.com/axon-7/how-to/guide-unlock-bootloader-easily-t3704595
The reason you lose your fastboot menu because you unlock BL with another image (using Axon 7 EDL tool perhaps), but if you do unlock with turkdev image in tutorial, your fastboot menu will stay there

Maybe by using Axon 7 EDL toolkit to enable fastboot first (Unlock option), then "fastboot oem lock" in fastboot mode. Refer to https://forum.xda-developers.com/showpost.php?p=78267172&postcount=200 . Warning : you need stock ROM (no changes in boot, recovery, system/root etc...) to avoid bricking your phone.
