Okay, let me start from the very beginning. Yesterday I met up with a guy who offered me his 2DS. And so I bought it off him. He told me it had CFW (please forgive me I have absolutely NO CLUE whatsoever on how any of this works). When I arrived home, I decided to format the system entirely. After doing so, I thought it was cleansed of everything CFW or arm9loaderhax or whatever it was. The next day I decided to use it, and founf out that one of the apps (the one with an exclamation mark, the warning thing) was hiding this thing called FBI where it could install CIA (well that's what it said in here) and stuff like that. So being the reckless person I am, I formatted the SD card using my phone and put it back. For nearly three hours I was worried because all the 2DS would do whenever I pressed the power button is that the blue power indicator would blink once, go off, and that's it. After searching for solutions online I found how to make it turn on and that I have to download and copy this arm9loaderhax.bin into the SD card. It turned on, much to my surprise. However, it displayed these options for the hack, and I was pretty disappointed because I never wanted the 2DS to have any of this in the first place. I pressed start to exit the menu as indicated, and tried to fiddle with the SD card a bit more. I found out that for some reason my 2DS wouldn't turn on unless the SD card contained the said arm9loaderhax.bin file. I even bought a brand new 8 GB SDHC card (like the one already on the 2DS) and tested it but it didn't work. Is there anything wrong with the 2DS or something? Sorry if I don't know any of this, I'm a noob when it comes to hacking and I've never ever encountered such a problem. Is there anything I could do to make the 2DS work even when I remove its SD card? How about the 2DS being dependent on the hack? and also, how will I be able to permanently remove that FBI application that replaces the warning application?
