[ULTIMATE REQUEST ONLY FOR REAL DEVs]

I searched every single POST in this forum, and many many others.. and there is no one that has ever did this.
So i have a ultimate request for you, if you do it i guarantee that you will be the first who ever made that.
The request is simple:
Unlock the HTC Desire 310 bootloader. :)

I tried everything, from following the htcdev.com tutorial to unlock via fastboot... nothing worked..
When i follow the htcdev.com i go in fastboot and it gives me three dots: ...
The other way, when i try to flash a custom boot.img gives me security error 2017..
So in order for me to install custom rom's (i have made 1-2 ports) i need to unlock my bootloader..
How in the world do i do that? I don't have any idea. If you do - please, PM me, or write here, i will give you all the details you need, everything!

P.S I can't even boot into bootloader because.. it doesn't have any? Idk on other HTC there is a menu, here it just goes into fastboot mode.
Cheers!
