Invalid NCA Magic - NSP Won't Install

[sandcrawler]

I made a thread a while back about troubleshooting with NSP. I have put my system on EmuMMC and I've tried installing my dumps with goldleaf, tinwoo, awoo, tinfoil, etc. and none of them work. I get the error message about "invalid NCA magic" no matter which game I'm trying to install. I'm assuming the issue is with sigpatches/syspatch? All homebrew has been able to launch with no issues.

This is the tutorial I used to set my console up + the source I got my homebrew from. I don't know what I can do.

Install latest sys-patch sysmodule and restart your console, use awooinstaller for install the NSP and let us to know

Updated to latest syspatch + atmosphere. Tried using awoo. Still didn't work.


I get the error code InstallNCA:110: Invalid NCA magic

Are you sure your dumps are valid?

 

[sandcrawler]

I tried it with a different game and I'm pretty sure it's just animal crossing. Are there known issues wih the game?

No. Probably a bad "dump".
