@spkuja is the goal to restore a B9S to its original state (which is ntrboot?) or to NDS? In your attached zip you've added the nds.bin not the ntrboot.bin from the zip posted by @pandavova - if the goal is to restore the B9S to it's original state shouldn't it be the ntrboot.bin (as backup.bin) in your zip?
It doesn't really matter which one you restore it to as the official flasher will then work. The primary goal here is getting the card working again. Also, I did not test the other file in the zip, hence I thought best to go in this direction. Anywho, once it is restored to being able to function as a NDS flash card you can just run the flasher from the r4i-sdhc website and it will then convert it back to the ntrboot state.
