Hi everyone,

I was programming my STM32F405RGT6 and can no longer communicate with the board. It appears as a DFU device once I jump the boot pins, but will not appear otherwise. My drivers should not have changed, I believe that the bootloader has been corrupted. 

Where can I find the original boot image and how would I go about flashing it onto the board?

The System Loader is in ROM/OTP, it really isn't something you are likely to corrupt, or be able to replace/reprogram.

You likely have *other* issues. Look for more rational reasons why things aren't working. Like reset lines, power connections, internal regulation, etc.

If you have damaged the chip, your option would be to desolder and replace it.
