OTA should work fine for me. I'm currently 100% stock with a locked bootloader. I'm at work today, and have to pick my parents up from the airport tonight, so the earliest I could start flashing would be tomorrow. I'd like to avoid unlocking my bootloader again and wiping the device, but it's likely I'll do a factory reset soon after installation anyway, so what the hell, right?
EDIT: Also, since nobody mentioned it.
