Homebrew Please need HELP!!!

[oWnFuL]

Hello eveyone I'm new here and i need help with my o3ds.
Yesterday I've installed luma and all went right.Today when I tried to install CIA with FBI I always got an error at the end of the install ''failed to install cia 0xd8e0806a''
I didn't succeed to fix so I think to format my SD(moving first all files from root to desktop) card and try again.
Now the situation got worse because evey time I power up the console it asks me the luma configuration and when I click start button to save i can enter the menu but after i close an application those installed on sd disappear.When i reboot i do again the same thing asking me configuration.
Please help me because i'm not good in cfw in fact is my first time i try.I'm on an o3ds sys 11.5.
Sorry for the bad english i hope u can help me with this problem.

Perhaps your SD card is locked. If there is a switch on the SD card, try moving it to where it does not say "LOCK."
Otherwise, your SD card may be corrupted. In which case, you should try using a different SD card. You can test for corruption with one of these tools:
H2testw [Windows]
F3 [Linux]
F3X [macOS]

is finishing in 30 minutes.But i also noticed a strange thing.The sd is in the pc so i tried to power up the 3ds without it and...it has powered up normally with a cfw the console cant power up.What's happening

The Luma boot.firm is in the sd card, and the console won't boot without it. If you run the "setup_ctrnand_luma3ds" gm9 script available from the guide, you'll be able to boot into the console without needing to have the sd card in it.
