I've created similar threads, but my problem hasn't been solved yet. I have an o3DS, running RxTools 3.0 Beta 2, Emunand version 10.5.0U, sysnand version 9.2. My problem is that when I try to install some cias, it goes to 100% and then all of a sudden says "this cia is invalid" on big blue menu. I've tried many different cia installers such as FBI,devmenu,nasa. can't seem to get the cia downloaded onto my 3DS. has anyone seem to have the same problem? and no it isn't a title import problem, those are properly put it in. it's why I could install big blue menu through FBI installer.
