There are a few reason that I downgraded.
First first and most obvious reason is because I wanted to make a video
tutorial on how to do it that you can see on my channel by clicking in my sig.
The second reason is because I didn't want to get the update nag that I would inevitably get if I had to keep connecting to the internet to get to Gateway mode. I could just unlink the sys and emuNAND and then put in dummy wifi info under sysNAND and now I'm never worried about the update.
The third reason is because I don't wanna be dependent on network access to connect. 9.2 Gateway makes the system less portable.
The fourth reason is because it was pretty easy and I like messing with electronics!
