So I recently downgraded and I had originally started with: https://gbatemp.net/threads/the-easy-complete-comprehensive-cfw-guide-for-everyone.408685/. I didn't get too far in, I only backed up my 3ds, formated my micro sd to FAT32, and formatted my 3ds back to default. After that I went to TCPixel's videos to downgrade because I am more of a visual person. After I downgraded I got my old files from before I reset my 3ds to factory. I replaced replaced the dbs files from my original Nintendo 3ds folders with the ones I used for downgrading. My problem is that after I got those files, I lost my FBI and homebrew files removed from my home screen. Not only that, when I go to FBI on the homebrew and I try to install the cia's, I get an error saying that the installation failed. And on top of that, I can't link my account to my 3ds because I need to update. I need some help to get my 3ds to be properly hacked so I don't accidentally brick my 3ds.
