Supercard Mini SD issue gba

Hello,

I was upgrading my GBA Supercard Mini SD to v1.8.5.

I went through all the steps, and it was going fine. It was in the middle of upgrading, and then the screen turned white.

After turning it off, the card is no longer read completely, like the Nintendo logo on the start up screen.

I have tried on two other Gameboy systems, and the card is not read at all. Other GBA carts still work on both.

If anyone has any sort of fix, that would be amazing.

Thanks.
