start a new game in a new savegame slot, and you don't have to undo the changes, i just did to see if they would persist.
um....did you remember to add the file back into pak2.lp ? overwriting the old one?
only other thing i can think of is that i had no save slots in use when i created the new save slot (i deleted my old game)
note: changes i have successfully made
1)unlocking the existance of the two preorder saber crystals
2)unlocking the existance of the two preorder costumes
3)changing how much xp you start with
4)changing default starting difficulty
5)unlocking all cinematics, artwork, and database
6)unlocking and having available 2 of all saber crystals
7)unlocking and having available all the costumes
8)unlocking all campaign missions and challenges (not the "DLC" missions or challenges)
9) altering the max HP and Force recharge rate
note to the guy who edited cheat/holocron unlocks, unlocking them is just telling the game that they have been used...the act of getting them/using them is what activates their effects.
PM me if you would like a fully unlocked savegame where the campaign has been played through twice (first on hard for evil ending, second on unleashed for good ending), none of the challenges completed.

[Edited by MJALowe, 11/4/2010 8:31:35 PM]edit3: the save game WILL NOT give let you use the preorder/DLC stuff or the max health/force regen changes, those require a few other files to be edited and they have to stay edited
