Board not entering DFU mode

My Spider v2.2 was recently entering DFU mode when putting jumper on BT0 and 3.3V. This won't work anymore. I flashed it a few times but not it's not entering the DFU mode anymore. Tried several USB cables. The 3.3V led on the board is not showing anything either. I can't flash via SD because the board has no bootloader right now.

Is there anything i can do? Any similar experiences?

I had the same issue, I was able to reflash firmware via a USB ST Link Programmer and use STM32 ST-Link Utility.
