Stuck in bootloader
This is my very first post here but I'm following a lot of topics here. I'm French so excuse me for my poor English
Okay I've got a big problem with my HTC One. I wanted to unroot the device by relocking the bootloader and turning in S-ON. Which I managed to do (even if it was written Relocked instead of Locked but anyway ...). Thing is that I'm now stuck in bootloader and I can't install any custom ROM. I can go to the recovery but I don't have ROM file in it.
I try to do the adb commands on my PC but I've got error messages like these :
error: device not found
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
Can I use ADB while in bootloader ? Fastboot seems to be ok (it recognizes my device) but I really need to install a ROM on my device if I want it to reboot.
I'm really stuck and my phone is useless now.

I hope you'll be able to help me.
Thank you very much,
