There are many different methods that work, hence the different ideas. We're not there with you so it's impossible to give 100% accurate advice. After rereading the thread, you've been given some solid advice from some very knowledgable and successful growers. While your substrate is working on producing fruits, you work on patience. Failed attempts and months of waiting are all part of this hobby. Your tub will fruit when it is ready.
However it seems you keep changing the conditions the tub is in. This could have stalled your grow (or it just stalled on it's own, APE is very tricky). I'd put down a layer of bubble wrap/wax paper on your substrate to create a CO2 layer for 2-3 days to "awaken" the mycelium. One of my APE tubs was fully colonized for 2 and 1/2 weeks. Just like you, I was panicked and kept messing with them. Then one of the OGs described the above procedure. I did the method described above, removed the bubble wrap, and three days later it had its first pins.
