So I got mine all assembled and everything is looking great, but flashing it is being a real pain in the ass. I've followed all the instructions, and when I go to flash it I constantly get the "did you forget to press the reset button" message. I followed all the instructions in the main post, but still nothing different. Is there something on my end I'm doing wrong that would cause this? I've tried everything a quick google search brought it (hold it down for over a minute, press it during, press it before, etc) but nothing has worked.
