I installed CFW on my N3DSXL a few years back. Things were going smoothly until I closed the system and opened it. The screens were both black and the power LED flashed blue for a second before turning back off. I had assumed for years it was bricked and put it in the closet. Recently I discovered my unit has an IPS screen and decided I would try to save it. Long story short I was missing a file in the root of my SD card called "arms9loaderhax.bin". I was able to find it and now my 3DS works again. Unfortunately, the laptop that had my old files was reset and given away and the SD Card I used with my system was formatted and has been moved to another system. Is there anyway to uninstall the CFW on my system at this point? The only things on my SD Card at this point are the default folders the system adds and the arms9loaderhax.bin file.
