I recently tried to follow a guide to downgrade to 2.1. In doing so I made a back up, or at least I thought I had, and couldn't get my N3DS upgrade past 2.1. I cart updated to 4.5.0-4U but now I'm stuck and don't really know how to upgrade past this without bricking. I also reformatted my SD Card thinking it would put me back to 11.2.0-35U but it didn't do anything besides clean off the SD Card. Any help is appreciated!
