Failed to install modded aldronix on even one device after 5 attempts

I have paid for modded andronix.I am a doctor by profession.The steps in the installation process of aldronix provided in the app aldronix should be provided in a pdf format .The video help provided by Delviz technology is too fast and it is very difficult to coordinate between watching video and installing and setting up termux,vnc client player simultaenously as even one small mistake makes us to start from scratch and waste one so-called download attempt in your aldronix app.Hope I could explain my situation.I tried installing 5 times and now I have been able to install real vnc client but local host in not connecting.So I need to install again and find out what I did wrong.You said that paying for modded system brings readymade linux but it is quite far from true.
