Do i get banned if i play during the FM and HP event with an account where i used cheat but on a device with a clean install without the mod menu?
You mean, playing on the original app from play store with your "mod" account? If that's what you mean, you'd still have a risk of getting banned. I've tested this on my throwaway account, changing your apk to the original apk doesn't protect you from JC's cheater screening. Because you had
used the mod service before you changed your apk, the hack had altered your game's code. You'd immediately have been busted the moment they check your account.
