Can I guess your system is not "New 3DS"? Because that error only appears if you are actually trying to install an CIA that are not supported in old systems.
Which I realized that already in the source code of FBI:
Code:
if(R_SUCCEEDED(APT_CheckNew3DS(&n3ds)) && !n3ds && ((titleId >> 28) & 0xF) == 2) {
ui_view* view = prompt_display("Confirmation", "Title is intended for New 3DS systems.\nContinue?", COLOR_TEXT, true, data, action_install_cias_draw_top, action_install_cias_n3ds_onresponse);
if(view != NULL) {
svcWaitSynchronization(view->active, U64_MAX);
}
if(!installData->n3dsContinue) {
return R_FBI_WRONG_SYSTEM; <-- it jumps to here.
}
}Can you confirm to me that you are trying to install on o3DS instead of n3DS?
