Hello, I've been following this guide on github and I'm stuck on the emuNand downgrade. When I launch sysUpdater in emuNand and press Y to start, it process files, says INSTALLED next to them but at some point (after around 1min) its stop with the error: Code: fsException: fs.cpp:117 Result:0xD8E0806A failed to write a file! Did you store the update files in '/updates'? I reflashed the emunand backup 3 times and tried the downgrade 3 times, always the same error. stre_LKnight from the IRC channel suggested to unblock the update zip before copying the files on the SD but, that sadly had not effect.
