Please have a look at this chapters in the reference manual of the 
stm32F4xxx microcontrollers (RM0090):
3.6.3 Read Protection (RDP)
3.6.1 Description of user option bytes
3.8.3 Flash option key register (FLASH_OPTKEYR)

And after that you should read in the documentation of openocd/gdb about 
reading and writing memory.

I haven’t done this before. So I can't give your more advice to do this.

Greetings
Oliver
