Did I just increase DS1022CD bandwidth four times?

Probably you are already familiar with the famous DS1052E hack where guys were able to double and even triple bandwidth. It happens that on my table is DS1022CD scope with 25MHz analog bandwidth. And this hack doesn’t apply to my model. We all know that the same series Rigol oscilloscope models tend to have identical hardware, whether 25MHz, 50MHz or 100MHz analog bandwidth. Of course, the sampling rate (400MHz) stays the same. So it all lies in the software. I felt that someone would figure out how to do this with this pretty old oscilloscope. And here it is – a hackaday pointed to a piece of great news – a simple way of changing the model from DS1022CD to DS1102CD, which converts analog bandwidth from 25MHz to 100MHz. This is quite a step without spending a penny. Andreas Schuler (aka Krater) shared a simple method of doing this without using any serial interfaces and firmware updates. By following his step by step guide, you can do this as follows:
