So for the time being I have to put modding the second 3DS XL on hold as I've stumbled into a major issue with the first 3DS XL that I thought I successfully softmodded.
After completing Step 5 and doing everything pretty much to the letter, the console ran fine. It was running on Sys 11.0.0-33E and was functioning, and all the homebrew/additional options installed were also working. I had since turned the system off (roughly a day ago), and only just turned it back on an hour ago. Well, I tried to.
For some reason my system seems to have possibly bricked itself. The console is now in a state of the power light turning on for a brief moment before going back off. Audio and screen to not initialize, and recovery mode is inaccessable.
I've tried changing out the battery as well as removing the SD card, it doesn't seem to want to boot up now despite coming out of the guide pretty much fine.
EDIT: So I tried putting the SD card back in again and it seems to have booted up now. Is it supposed to have the SD card in in order to boot up? If so what file/files are needed on the SD card that tells it to boot? I apologize for my noobishness on this. :S
