Hellpoint

I managed to finally get it to work. So what I had tried was just doing the code wherever, random time. Then I tried it during Hell Hour, then during Hell Hour specifically at the Breach that you get after the very first boss, and again at the Observatory. None of these worked. I decided to try it again next time Hell Hour occurred wherever I was at the time and this time it worked. I don't know if the location actually matters or not, but I did it at the Ikari Walkways. Another thing I'm not sure that matters or not is my unsuccessful Hell Hour attempts was the one that's on the right side of the clock, this time the one that worked at Ikari Walkways it was during the Hell Hour that's on the left side of the clock. So I can't confirm what specifically it is you need since the location and time were both different at the same time, but I believe it more to be the time. I think you need to put the code in during the Hell Hour on the left side of the clock. If not then it is probably just completely random whether or not it decides to work.
