Can't Unlock Boot loader [Error: FAILED (remote : Not implemet.) - BLU G5

Not sure if this is the right place for this but here goes:

I've been trying to unlock a Blu G5 - I've gotten as far as patching the disk image and all that is left to do is just flash the image onto the phone.

The issue is whenever I try to flash something onto the phone I get the following error : "FAILED (remote: Flashing Lock Flag is locked. Please unlock it first!)"

When I go to unlock through Flashing unlock I get the error in the title - OEM unlock gives me cmd not found.

I have USB debugging and OEM unlocking both enabled inside the app settings. I'm not sure if its pertinent but on Magisk I see "Ramdisk : No". I've also been unable to get into recovery mode despite trying every combination possible except for once on accident (which I haven't been able to replicate).

Any help would be appreciated, Thanks!

What command are you using for unlocking? The last valid command I knew was fastboot flashing unlock.

Something to keep in mind: When you unlock the bootloader, it wipes the device. Backup anything you need to keep.
