Hacking Gateway 3DS Save Backup for CFW doesn't work

[MasterKillua]

Hello there. I'm trying to use my Resident Evil Revelations and Mario Kart 7 retail games saves for CFW.
I dumped the saves with Gateway, then I replaced the cia saves with the saves I dumped.
For example, Resident Evil Revelations save is "ABRE.SAV", so I go to the SD and replace the 0000001.sav with the "ABRE.SAV" one, then I start the game in my CFW and a message appears saying that the save is corrupted.
What can I do? Tried with MK7 and RE: Revelations only. I sell my MK7 game yesterdayn just have RE:Revelations
I tried to dump the saves with savedatafiler (cia) but when I start it, a black screen appears with an SD error.

I'd like to play RE:Revelations at least with my retail game save and I would like to dump AC: New Leaf and Zelda ALBW saves.
Thanks in advance and sorry for my bad english.

It'll work on the cfw.
