[HELP] stuck in fastboot..... topic

i forgot which rom im on, but it was the latest Lollipop ROM that needs the firmware update. i know the rom has a updater in the About Device.

well anyways, i have dirty flash with this rom from the updater, and it was fine. today i wanted to updated again so dirty flash again, but then after it was done it just reboot into fastboot. and i have tried all the ways i can from searches, but still end up at the fastboot. now im stuck and dont know what to do.
