Issues with bootloader version when trying to install lollipop on HTC One S

Hi Guys I tried to install lollipop (cm-12.1-20150922-NIGHTLY-ville) on my HTC One S. I installed recovery-clockwork-6.0.4.8-ville and everything work just fine. But no matter how many times I try the same thing comes out. It says there is an error with bootloader version. It seem like this custom ROM is supported just for 2+ bootloader versions, mine is 1.4. Is there a workaround, or am I doing something wrong? I have no OS on my phone just fastboot access.

My HTC is also unlocked and rooted. And I am on ubuntu.

I am new here, really need help

Many thank you, I appreciate your assistance.
