If the phone is still S Off you absolutely can do it. I did it. It's possible. So I'll explain it to you.
1. boot into bootloader. Edit : Turn off fast boot first
2. see if the phone is S Off. If it is continue. If not, you're SOL.
3. Update to the custom recovery I've attached. (drop the img file onto the SD card, boot into Bootloader and accept the update)
4. reboot. Remove the img file from SD card, drop new ROM .zip on there. Boot into the recovery.
5. Flash new rom.
6. Hit thanks
