Edit: Hey folks, I realised that I was following an old guide, so I formatted my 3DS and SD card and started again. I am now following a guide from this site: https://gbatemp.net/threads/tutorial-installing-rxtools-custom-firmware-3ds-and-2ds.390867/ but I'm still struggling. I get to this part: To finally inject BigBlueMenu into SysNAND, rename the BigBlueMenu-with-banner.app file to hs.app and place it on your SD, overwriting the one that is already there. Launch Decrypt9WIP again, and navigate to SysNAND File Options. Choose the option to inject the hs.app But the hs.app doesn't appear. On the Decrypt9WIP menu, I go to "SysNand Options" > "File Inject" but no "hs.app" is there. Plenty of other files but not the one I need. Please help. For the record, as I followed the guide, the hs.app first appeared on the root of my SD card. Do I need to put it somewhere else? Thanks in advance!
