Flashing reverts


So. My problem is whenever I try to flash one of my cards, it’ll say it flashed, then it doesn’t work. Without the patcher, at least it would show up in device manager with the triangle. Now nothing. And so I try flashing the same bios onto it. And according to Atiflash, the bios that was on it was the same one from the beginning. In other words, it was 12 before I flashed it, then after I flashed it to 10, it still said it was 12. I hope you’re following. Sorry if it’s confusing. If you have any questions, just ask. I just want to know how to fix the problem. I know it’s flashable. The bios on it at the moment is one I flashed onto it.
