What part specifically? What did you do exactly?

You want to try and connect to the part and do a Mass Erase. Try also with BOOT0 pulled high.

I was working on srm32f407 discovery board in coocox .

I was doing write protection program, after first run I want to disable the write protection  so I download code in board but  error is coming flash drive exicute error.

First thing I am not able doaload my code in board so programing wont help me . 

So I was using STM  st- utility  ,I can erase  chip or sector but  while erasing it shows me  some pages are write protected so not able erase.
