The device isn't bricked, if it powers on at all it isn't bricked. You need to unlock your bootloader again and install the latest TWRP recovery. When flashing ROMs are you remembering to flash the boot.img via fastboot? Perhaps you should check out the Evita FAQ thread and my How-To Guide For Beginners thread, both links are in my signature.
