SafeNANDManager

SafeNANDManager copied to clipboard

Directions: Just boot SafeNANDManager and press A. It will dump a nand.bin with nocash footer to your dsi at DT010203040A0B0C0D/nand.bin The folder will be next to wherever you put dumpTool.nds. And obviously, your foldername will have different characters. It's console-unique. You can also restore a different but still console-unique nand.bin

General Info: This tool should create a nand.bin identical to fwTool.nds 2.0. The same holds true for its nand.bin.sha1 file as well. If this isn't the case in your neck of the woods, please make an issue :) (note that identical nands can only occur if both app's output are compared in the same hbmenu session; booting to dsi home menu in between will undoubtably change NAND contents)

Features:

• Completely open source.
• Lots of checks, including verifying the nocash footer will decrypt the outputed NAND. Low battery and insufficient SD space are also checked.
• Project has a permissive license, and more importantly, its dev is permissive. I don't care what's done with this post-release as long as credit is given.
• Simple operation. Just press A to dump, or Y to restore, and watch it go.
• You can cancel the dump in progress. The incomplete nand will be cleaned up.
• A little bit faster than fwTool. Should complete in about 7 minutes. NAND restore may take longer.
