As you can see the videos below, they made explosive sound, but there are no details how exactly on DAW.
How to make it?

Err, ?. As you can hear in the first vid (btw, what's the second for???) he takes away nothing in the chorus itself, rather the opposite, but in the bridge/part right before the chorus. In the very short example he provided you can clearly and without any difficulties hear, that there are more fx, instruments and vocals in the chorus than in the part before.
No magic and mystery happening. That's just called arc of suspense or build up.

 

I followed and gave it a shot as he said, but it didn't sound like that. That's why I linked another example. The music of the beginning of the second video is also kinda explosive sound, I think..

 

There are many ways to do this. Omit elements, filtersweeps or low/high shelving cuts, orchestrating things in the higher ranges, risers, soundscape-narrowing (stereo/mono balance automation), effect return riding, etc (before the chorus/drop/whatever). It's all psychoacoustic effects of omitting and then bringing it all back on the chorus. The psychoacoustic effect on making things mono is to make it appear "farther away", as opposed to wide/spreaded and near, just as it happend in real life.
You can also do master fader (or main bus channel) volume bump when the chorus hits, to enhance it even further. Like "Here, we're back to normal!".

I'm not sure if you're mixing up some things.
In the first vid he made a short dry and mono vocal-only break and the chorus starts with full instrumentation and stereo fx.
The music in the second vid is mono and just a normal arrangement with drums bass and guitars with a short snare-only break.

Can you provide your unsuccessful attempt (maybe even in PM) so I can better understand where exactly the problem is?
