Okay, so I haven't really been up with the hacking scene for the 3DS in a while and so I decided to update my 3DS. Now I kind of have a problem and maybe someone can help me out. I visited this page: https://3ds.guide/ I clicked [Get Started] and clicked on the 3DS since I'm using a old 3DS XL. My sysNAND firmware is 4.2 U and I clicked "Decrypt9 (MSET)" on the column 4.0.0-4.5.0. I followed STEPS 1-9 just fine and onto the next page "2.1.0 ctrtransfer." The warning of "Having a backup of your device’s NAND is REQUIRED. You will be prompted to create one as part of the steps if you do not already have one." I definitely followed that and made a backup of my sysNAND (NANDmin.bin). And it was successful. Or so I thought....? Anyway, I followed STEPS 1-8 on the "2.1.0 ctrtransfer" page (downloaded all necessary files, copied/moved them onto my SD card..etc). Afterwards, I continue onto the next page " Installing arm9loaderhax" Then downloading all the necessary files on this page and following each section step by step up until " Section IV - Restoring the System." Then came STEP 3 : Go to “SysNAND Restore (keep a9lh)” and restore from NANDmin.bin. On my 3DS, I select the restore sysNAND (keep a9lh) option (in Hourglass9 v1.40) and I get this message: Selected: [SysNAND Restore (keep a9lh)] No usable file found SysNAND Restore (keep a9lh): failed! Press B to return, START to reboot. Did I do something wrong? If the SD card isn't inserted, the blue light turns off right away and shuts the 3DS down. If the SD card is left inside, the screen stays black. And if I turn it on with the SD card inside and the screen is black and then I remove the SD card, it loads into the 3DS main screen. Please help, thank you.
