I am attacked on sight by the NCR. I used console commands to set my reputation to idolized, yet I am still attacked on sight. How can I fix this?
You are wearing Brotherhood power armour. After what happened at Helios One, the two factions have an intense hatred of each other, and the NCR will attack Brotherhood soldiers on sight. Unfortunately, that includes you. Try wearing normal power armour instead (i.e. power armour that does not include "brotherhood" in the name). You can buy most power armour from the vendor in the Hidden Valley Bunker, but make sure to buy the correct set.
