I have a android named Symphony r30.
Android version: 7
Chipset: mtk6580

The Firmware of the mobile is Signed.
I unsign the boot image by Unsign Tool by Hovatek.
And patched by Magisk Manager.
for flashing the boot I'm trying to unlock the bootloader with Bugjaeger mobile adb and otg cable. 
Everything is ok, Just when i enter the command "fastboot oem unlock". then i got an error " Unknown Command". For unlocking bootloader of other devices the command workes well. 
how can I fix it???
Thanks in advance and sorry for my poor English.

Try unlocking bootloader using the method @ https://www.hovatek.com/forum/thread-19578.html *try all the 3 commands

Also, you can try flashing the patched boot.img using miracle box or spft without unlocking bootloader.
