well first off look on your mw2 case it will say something like BLES00683 thats the place where u put your patch when u were on the CFW or what ever.... now when you use RFOM (resistance fall of man) bypass that then changes to BLES00001 for some reason. i was going to post this much eariler so someone could see if u locate the BLES00001 and place a mw2 patch in there and see if you can host a challenge lobby on the bypass. i dont think anyone has tried this yet. if u do try and it works pm me and +rep
