Here is a site for this board that seems fairly active. All STM32F4 tutorials - STM32F4 Discovery
I would hazard a guess that the bootloader on your board may be corrupted. Without more information, I cannot tell. If you can get a fresh bootloader back on, that may resolve the issue.

Re: STM32F4 Discovery board & ST-Link Utility - Core Lockup

Greetings all,
After about a year I have returned to playing with STM32F4 Discovery board. Last time I have used the board and ST-Link Utility everything worked as it should.
This time however, it doesn't. I connect the board with ST-Link ( USB driver ), erase the flash, and upload a .bin program ( the demo program that MCU came flashed with at purchase ). Hex program and ST-Link worked well last time I used it.
Now when I go to Target -> MCU Core and select "System Reset", I get "Core State: Lockup". Therefore I can't Run the application ( I get "Unable to run application" ).
What could be the problem in my case ? What could change since the last time I used the board, when it all worked well ?
Thank you and kind regards,
A
