Given that my recollection is hazy about what I did with the stb, (given that mine packed up before most!), I do have a file stored with the v1100 one. It's called AD3000VA.bin I have no idea what it is or if it is the boot strap except to say that it won't be anything to do with the Viaccess model 'specifically' in that I only kept files that I used. You are of course welcome to try it.
