I was using kitkat with fbi's remote install to install pokemon omega ruby cia file on my 3ds. AFter it reached 1.2gb, the installation froze so powered off the 3ds by holding the power button. I tried using sd management to transfer the file to my 3ds but it said my space was not enough. I think the uncompleted installation has taken space on my sd card. P.S:my sd space was 2.1gb before I started the installation but after rebooting my 3ds the space became 832mb.
