I am having probs running MW3 using IOS250 d2x base 57. I am trying to get cIOS 224 installed to see if that works. The Uloader installation app won't work I can download the WAD from ModMii, so can I just install it using WAD Manager instead? What I am curious about is - how important is that IOS that you choose to install the IOS? Does it matter which you chose? For example, can i select IOS249 to use when installing, and then actually install a CIOS of a different version number? Is there a relationship between the two, or is it just that a 'valid' cracked IOS is required to enable a WAD to be installed, regardless of which cIOS it is?
