1. First of all - have you got the 3.03 OS to load onto the the card?
2. If not, where are you going to get it?
3. Finally, even if you have the OS, the Tit3 cards are probably not 6464c (and probably not 7272c either) so loading to a 6464c would never work.
I have a couple of Titanium 2, OS 2.02, and have tried to write files like TMB, WLTDo2.2 and NagraEMU. But without any success. Tried to write with CAS Studio and 2 titanium loaders, but they all give me write error. Cards are all virgin
