[Q] Stuck at HTC logo Can't enter bootloader topic

So I was trying to install a new row and I was using MultiRom Manager to have 2 roms , Stock and Maximum. Well after MultiRom installed what it needed in TWRP my phone rebooted and is now stuck at the HTC logo with this is red " This build is for developer purposes only Do not distribute outside of HTC without HTC's written permission. Failure to do so will lead to legal action" I've tried the volume button trick where you hold power and volume up then release and hold volume down but I can't access the bootloader no matter what.... What should I do here to fix this?
