How to reverse finsish all research?

[BRAOUG]

So I used dev mode to finish all research to make a cheat base. Is there a way to take it away again. So that I am going to have to research all again?

Not with the Dev tools.
You can edit the safegame and remove the researched techs.

Next time you want a cheat base, use the God mode.
Enable God mode, then you can build all things without research.
And when you just want place the blueprint without instant building, select the one you want to place, turn off god mode and you are still able to place the blueprint your pawn's can finish.
