i have to xbox 360s both flashed when i take the hdd of 1 and put it on the other it cums up with profile corruped and the game saves r i put it back on the other 1 and its fine
that was happening to me, the way i fixed it was to delete the corrupted profile (on the console that corrupts it) (delete profile ONLY! not profile and saves) then ater i deleted JUST the profile, i just connected to live and recoverd my profile and all worked great again! give it a shot, i have done it several times with no problems...
use the batch con flag remover... its better than recovering all the time and you keep the achievements you earned
have tryed what u said b4 when it first happen it started when the kinect dash came out and that ap25 thing i just stopped useing two xboxs but they have sent out a new update i hve to use my second xbox but everything is corruped on it im going to have a mess around later might have to sit dwn and do a big rehase risign but i cant connect my other xbox to live coz it will update so dnt knw what to do thanks for your help oh and none of my xboxes r banned
funny you should mention this as my brother in law is/was having the same problem, I told him to put his profile on a usb memory stick and use that to transfer between xboxes (keeping his saves on there too) and that seemed to do the trick. Also the new update makes GOD/Arcade games profiles not work too
