The point is people need to pay attention and understand what they are doing. he cannot have tried all possible combinations and not found one which works.
This is the best and most valuable help you have got so far:
Please learn how lighting circuits work, and what different switches do. Come to genuinely understand how the things you want to fiddle with actually work.
So he went ahead with the job even though he didn't know what he was doing, he didn't wire the new switch in the way the old switch was wired (despite thinking he had), tried to make it work by guessing, didn't hit on the right set of connections (despite believing he had tried every possible one), and ended up with no lighting.
I am not trying to rub the OPs nose in it - I do genuinely hope that this will be a salutary lesson to others of the vital importance of learning how lighting circuits work, and what different switches do, and acquiring a genuine understanding of how the things they want to fiddle with actually work.
I don't think the OP needed to understand how all lighting circuits worked to replace one switch with another.
Maybe he has learnt to pay full attention when disconnecting switches, mark wires and take photos.
Yes he tried several combinations and then realised he would be better seeking advise on a friendly forum. Unfortunately he found this forum instead.
It is indisputable that he needed to know more about how what he wanted to fiddle with actually works than he did.
If he knew how switches worked he would have had a much better idea of what each conductor was for, and would not have suffered from any confusion (if he did) between C/L1/L2/L3/1-way/2-way/etc markings on the terminals.

Thats a bit unfair on BAS, in some ways i agree with him and his internet name, ban all sheds, though thats possibly a bit extreme. as a lot of the trade also use them.
Its all to easy to see these nice shiny switches in B and Q, wickes etc, and many people truly beleive they know how to fit them, when the reality is they dont.
Luckily in most switches swapping wires and quessing is not too hazourdous, but in the event neutrals are present it could get nasty

A girlfreind brought a replacement socket once and it wernt till the screwdriver blew up she realised she should have turned the power off, although unharmed , she learnt the wrong way, not to do that again

Please do not make the mistake of thinking that it is my fault that the dense and the deranged get agitated because they have viewed a post of mine through the distorting lens of their inability or unwillingness to read perfectly straightforward English.
