Hi guys. Sorry to trouble you again so soon but I've got a serious problem on my hands. A few hours ago, I had to force my computer to shut down. Unfortunately, my 3DS' micro SD card (along with all its CFW contents) was not plugged out before the shut down. When I turned on my comp again, the card was corrupted, and have now been lost. I've tried to recover the data and repasted it in the SD card, but the 3DS won't recognize the old data anymore. The worst part about this was that I made a really stupid mistake: I upgraded the firmware to 11.3, AFTER I've installed the CFW properly and backed up the nand.bin and everything. I thought it was safe to upgrade. Now I can't restart the whole CFW process again. So here's the thing: I would like to know if that nand.bin and otp.bin I had backed up following the guide could help me restore my old firmware version again, or something like that, so that I could reinstall the CFW or something. I've tried booting up decrypt9 to restore the nand, but decrypt9 isn't working anymore either. That's why I'm here, asking for your assistance. I mean, that nand.bin backup I made using the 3DS CFW guide had a purpose right? In case something like this happen? There's got to be a way to restore the whole thing, right? Please tell me there's a way. Sidenote: I also have a files9 backup on my computer. Not sure if that will help in restoring the nand/cfw.
