Hi, I am looking to have my xbox 360 flashed again. My xbox360 was flashed around April of 2009. Unfortunately I have no idea what flash was done

The newer games with the higher waves don't work for me unless I run a waves patcher first, and just recently NFS Hot Pursuit will not run at all cuz of the AP25 protection. Do you have a flash that will fix my box up. I live in Fresno, so I would probably ship it to you and then pick it up when done. Thanks! I will see what drive I have tonight. I'm not too sure. Thanks so much!
