NOTICE: These tools are currently being reworked and the instructions below may not be applicable.

Current tools for extracting XSR1 require Windows.

1. Download rfs_dumper.exe from Github
2. The input file should be stripped of everything before the first 91 5A 49 2C header. In HxD, you can do this by going to the menu and selecting Search>Find, then selecting the Hex-values tab and pasting in 91 5A 49 2C. Once you find this location, delete everything before it. Save this new file as input.bin.
3. Place onenand.bin, onenand.oob, and rfs_dumper.exe in one folder. Open a terminal in the folder with the dump (onenand + oob) and rfs_dumper.exe. Use the following command:

   .\rfs_dumper.exe input.bin output.bin

The file system can now be read and extracted with TestDisk.
