OpenSDA on K22F bricked

Quite a problem.

It appears I bricked the bootloader on one of my K22F boards.

How do I recover it? I tried flashing OpenSDA with an external CMSIS-DAP adapter using OpenOCD.

Even though it said it had successfully managed to write the data the bootloader isn't working.

 

Could someone please give me a hint or two as of what to do in this situation?

Thank you
