Hey there, I recently downgraded my n3DS (EUR) to 9.2 and set up an 9.5 emuNand. Everything seems to work fine, I injected FBI into H&S app and successfully installed some other cia tools with it (sysUpdater, NVER, BigBlue etc). Also tried to install a Yokai Watch US dump, which also worked on first try. (Thus region doesn't seem to be a problem). However, installing an english patched MHX cia fails, even the original japanese version does. An EU Xenoblade Chronicles dump fails to install as well. I tried using two rxTools versions and CakesFW, also tried installing via FBI, devMenu and BigBlue. No matter what I do, I keep getting an "invalid_signature" error. (Currently trying another install, I'll update the post with the exact error message) For everyone else, these dumps seem to work fine, so I doubt that those are faulty. Any ideas?
