If a method to crack an app requires root, the developer of the crack (or the instructions) should say so. I wouldn’t recommend rooting just to try if you can’t already find the information yourself.
I’ve never run a crack on android, only run patchers and pre-modder apps, so I can’t give you advice on that specifically.
Lucky patcher is just a patcher and says it should run fine without root.
No, the explicit ones are for killing a cop or being an immigrant, for which he knows he will have wide support among Democrats.
