Need help in Byzantium - Everyone is hostile

[Stormtrooper]

Hi,
I'm kinda stuck in Byzantium. I did the quest where I had to kill the scientist, but decided to let her live. But to do so, I had to kill some Board goons. The problem is, that now I get attacked by the guards there as soon as I enter the planet. Which means I can't properly continue my run. I tried sleeping days with my char, but that didn't make the heat die down. Is there another way to make the hostility sink, so that I'm not attacked all the time? Or am I screwed and need to load an older save?

How many days? I think you need at least 72 hours for most faction/vendor resets.

If your rep with the Board was already kind of low, you might just be locked in on hostility. That doesn't have to break your run, though. Shooting your way through the Board is a valid option if you don't want to reload to before you saved that scientist. Could always reload and do some quests to curry favour with the Board before you help her, too.
