Hey guys,
I have ZTE Red Magic with an unlocked bootloader. It is my first time rooting, and after unlocking the bootloader, I wanted to boot TWRP. So I booted into the bootloader, entered "fastboot boot recovery.img" and I got this message:

downloading 'boot.img'...
OKAY [ 0.579s]
booting...
FAILED (remote: unknown command)
finished. total time: 0.582s

The installation of recovery was successful as I typed the command "fastboot flash recovery recovery.img"
target reported max download size of 536870912 bytes
sending 'recovery' (26721 KB)...
OKAY [ 0.580s]
writing 'recovery'...
OKAY [ 0.001s]
finished. total time: 0.583s

I have absolutely no idea what I'm doing wrong. pls help
