help unlocking bootloader!! error: oem unlock is not allowed. :(

hey guys,
i was trying to convert ZUI to CM and i messed up somewhere and i am only able to access fastboot mode now, my phones bootloader was unlocked before but some xda member told me to relock bootloader and try unlocking again to flash files but it didnt get unlocked after relocking.
so the present situation is i have a locked bootloader in fastboot mode and no recovery.
i want to flash system images through fastboot mode to bring it back to life, but it wont let me do it as bootloader is locked.
i tried unlocking the bootloader and it gives me the below error.
"FAILED. remote: oem unlock is not allowed"
how to get rid of this error and unlock the bootloader?
any help would be appreciated guys.

Go to fastboot .
Connect zuk to computer
Start adb
Use "fastboot -i 0x2b4c reboot-edl" y will reboot to dl mod and y can install right drivers for 9008 port.
If it not work than when y boot windows , press f8 chose "dont check drivers ....(something)"
Boot windows , uninstall zuk drivers , install it one more time and try to use qfil one more time .

Flashing original firmware

Hi, Can somebody tell me if its necessary to unlock the bootloader before flashing the official firmware. My device is not rooted and has a locked bootloader but as I wanted to flash the original firmware to refresh it, I was wondering if I can do it without unlocking the bootloader.
Thanks in advance.
Check this thread for EDL Mode https://forum.xda-developers.com/an.../guide-how-to-reboot-to-edl-fastboot-t3394292. Reboot to EDL Mode and flash using MI Flash Tool. This flashing not reuqires bootloader unlock.

Sorry but that is not correct, the A1 uses just fastboot, we don't use EDL.
Anyway just follow this guide

You just need to install miFlash or use fastboot commands if your more advanced, reboot to bootloader

The phone does not enter fastboot / bootloader mode

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
