Homebrew a9lh luma mirco sd corrupted, files recovered but will NDS work again?

[xWaterLily]

Hello everyone,

I'm not sure if I should be posting here but I really need help.

I have a9lh luma's on my N3DS which I was going update/change to b9s. When I put the micro sd card reader in it started acting a bit funny and suddenly the error message "you need to format the disk before you can use it" came up.
I asked some people on reedit to help me out. They suggested I recover my files. I gave that a go with what I could find (easeus data recovery wizard) this was the only one I could find that got most of the files and names correct and in order.
After doing this I am seeing that alot of folder are empty without any files e.g Luma folder

This would make me think that not everything was recovered.
Seeing as my NDS will only lightup and turn itself off again when the SD was removed and does the same when this one is put in (without being formatted)
Does this mean I have no N3DS now..?

Please can someone help me. I really dont want to lose my 3DS.
All hightlighted folders are empty

The folder "Lost Files" and "Raw Files" are new

If you updated to B9S you need a boot.firm on the root of your SD. If you still have A9LH just recopy the 7.0.5 Luma BIN to the root. The binary you currently have is probably corrupt.
