I presume you got the 18mm mounting bolts removed from caliper mounting brackets. Other than the one torx bit that should be it. I was going to replace my rotors but could not get the mounting bolts loose.
I've always used a torch (even just a propane or MAPP gas one) to heat the rotor between the studs. Don't have to get them really hot, just enough to get some quick thermal expansion of the rotor different from the hub. Then a few whacks with the dead blow and they pop free.
