I don't know where you got the part about no trim past 1.3g. It is true that the trim is inhibited past 33 deg bank in normal law, and that probably equates to 1.3g, but that doesn't mean that it will cut out at 1.3g every time. I believe the auto trim is restricted by bank, not g. Let me know if you find something that says otherwise. Additionally, the trim will NOT work in direct law, and in Alpha Prot the trim is inhibited, but only in the nose up direction.

As for the aircraft response, you are right, it will stop at 30 deg nose up per the pitch protection. As it approaches 30NU, the elevator will unload the airplane to 1 g (and the THS will, in turn, trim to streamline the elevator).

As the speed decays, the limit will gradually reduce from 30 to 25, again by using the elevator first and then using the THS to streamline it.

As the airspeed decays further, you would normally reach high AOA, but in this case, it is inop, which means you are in alternate law or worse, so High AOA protection is replaced by "low speed stability." At low speed stability you will get the "speed speed" warning a few knots above stall, and the aircraft will try to nose over further to avoid it. If you continue to pull aft on the stick, you can override it and induce a stall. Note that you will not get alpha floor because you are in less than normal law.

And now that I read what I just wrote, I would also say that the airplane will not stop at 30NU in the first place, because you were probably in alternate law the whole time (because you said High AOA protection was not active) so it will just go up to 45-85 degrees nose up, probably, depending on what kind of speed you had going into this thing, and give you a spectacular stall.
