[SOLVED - SOLUTION] Just get the latest version of Luma3DS (6.6 as for today) and extract what is inside the hax folder and arm9loaderhax.bin in the root of the SD. At root (sd:/) > arm9loaderhax.bin > 3ds >> Luma3DS That will solve it (at least for me it did). -- Original post: Well, after installing A9HL successfuly and injecting FBI and installing homebrew launcher and luma updater, and everything worked all right (downgraded to 2.1.0 and then recovered), well as I said.. then I did this: Powered on the 3DS. Went to the injected FBI in H&S. Went out. Went to the options menu. Went out and then the 3DS freezed. I forced turned off the 3DS. After that, I turned on the 3DS and after a second or so, it turns off. If I try with the SD off, it happens the same thing. Any ideas of what it could be?
