HTC Explorer: Unable to flash recovery, remote: signature verify fail

[Maven Maven]

I am trying to flash a `CMW Recovery` into my HTC Explorer device so i could install a custom rom:
Upon issuing command:

>fastboot flash recovery recovery.img

I get this error:

sending 'recovery' (4728 KB)...
OKAY [ 0.877s]
writing 'recovery'...
(bootloader) signature checking...
FAILED (remote: signature verify fail)
finished. total time: 1.467s

Can anyone please explain why is this happening and how can i solve this?
Thankyou
