K60 locked

Hi!

 

Unfortunately I locked my K60-Tower because I forgot to choose the K60X_Flash.icf file in the linker options (IAR workbench).

 

Then I tried to unlock it with the J-Link Commander ("unlock kinetis"), but without success:

What can I do to make the tower work again? The reset LED and the red LED of the J-Link-lite-Interface light.
