Writing to flash problem

I tried one of the flash examples for the STM32f4 Discovery. First i tried to read from adress 0x80E0000, then i tried to write to that same adress. After this, when I try to debug, i got the error "No source available for "0xfffffffe" ".

So I tried strapping 3V3 to boot0 and reseting it. When I try to debug now, I get stuck at:

  b  LoopCopyDataInit

and I am unable to start the debug (Stuck at this position and unable to pause debugger). At this point I tried to do a full chip erase, which lead me back to the 0xfffffffe error as mentioned above. I've tried to debug different projects that I know is working but with the same results.

Do anyone have ideas of what i might have done to my discovery?
