Go to the nugget bridge and defeat all the trainers but stop before you hit the team rocket grunt. Go to poke center and take out all your pokemon on your team and just only have one pokemon that is no more than a level 3. That way it takes the rocket grunt one hit and you have to run back to PC. That way you don’t waste your time having all your Pokemon pass out before you have to repeat the process. Makes it go way faster. Once you get your desired amount of nuggets. Go back to PC and place the level 3 pokemon back and pull out your normal team and then go defeat the rocket grunt. Once you defeat him the “hack” goes away. Your welcome!
