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.
thanks in advance!

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 .

There is no way u can re unlock the bootloader,but there is a workaround.Flash the beta marshmallow rom for 8916,watch the youtube video and check description,its a trick how to flash the beta.then simply flash twrp.the beta rom allows to flash twrp through fastboot.I found this method by myself over a month time

FRP unlock

Is there any way to unlock frp from the fastboot if the bootloader is unlocked and the device is bricked.
Already tried : fastboot oem relock xxxxx
Returns : command not allowed
I am on stock recovery and the device is bricked right now.
Help needed!Many thanks!

you can try this, I dont know how usefull it can be
I don't think there will be FRP because the V9 doesn't come with all the Google stuff. Unless, they were added afterwards by installing them all manually.
