Think about it like this. You erased the hard drive on your computer and installed a new version of Windows (or Linux/MacOS - whatever). But now it has no software installed so you can't do anything with it. That's kind of what what the RSA delete / master program is - it's like the operating system for the DME. It doesn't do much on it's own.

This sets up the computer but now it has no calibration, so the car won't start. Now you need to install the calibration, which is the rest of the data needed to run the car. The calibration is literally empty, because it gets erased when you flashed a new program (the RSA delete, or even an unmodified 0pa file).

Download the calibration (stock tune) for MI20S and flash it. It will work.
Thanks for breaking it down so that I understand the situation just roughly now, but cannot find the stock file as I wrote in other thread. Can It be found somewhere online?

I'm aware that I'm asking such silly questions and being dumb. Really appreciating your help.
