The other guides work perfectly fine, except for one thing that no one specifies.
Because of what the Resistor perk is, you must be moving while you're shooting the ground underneath you with a Plasma Pistol.
So, follow the other guides for what you need Loadout-wise, then:
Spawn in with the proper loadout
Look straight down
Start walking forward
Hold in RT to Overcharge your Plasma Pistol into your feet 4 times
Keep walking until your shields recharge
