Sms 4 cheats does not work?

I got a cheat from a friend where you can enter motherload to get more money. Schift> C. But that did not work. Also on the internet I have found several other cheats, even to get money, but no one works. He just takes screenshots…

I have a notebook from ODYS. I have Windows 10 on it.

[Ctrl] + [Shift] + [C]

Enter "testingcheats true"

then you can use all cheats
