RESET LEVEL

RECENTLY I PRESTIGED ALL OF MY CHARACTERS AND THE RESULT IS ALL OF MY CHARACTER END UP WITH 4 PERKS. IS THERE ANYWAY I CAN RESET IT BACK FROM PRESTIGE 3 LEVEL 50 TO PRESTIGE 3 LEVEL 1( I WOULD PREFER CHEAT ENGINE)

How did you prestige? If you used cheat engine already and know how to use a bypass here you are:
Find the empty item slot addresses for the character you need and follow this tutorial https://www.mpgh.net/forum/showthread.php?t=1443920 .
When you got your Addresses with prestige and level just change the level to 1.
If you're going to get a save error you need to do the following: Go to main menu after finding the prestige+level addresses with the tutorial I linked you, change the level from 50 to 1 and go fast in a KYF lobby so you're going to get a force save ,even if you get the save error.
