You can't get any achievements/trophies if you've activated a cheat, even if you deactivate it.
You can't!
If you enable or activate cheats on saints row 2 and save achievements/trophys cannot be earned. If you dont save while you activated cheats then nothing happens.
By doing special things. NO CHEATS! If you use cheats you will not get the achievements. If you don't know what you are looking for you can go to the game on your dash board and check what achievements there are to still get.
YES, There is so much more to do and if you want to have fun, look up some cheats, but if you have cheats enabled, then you can't earn achievements or trophies.
No
Because you've got cheats enabled. Try loading a different game save without cheats and you'll get them.
