Custom board bricked

Any suggestions for handling a bricked custom board?

I'm pretty sure I know where the problem is in my code, but now I can't reprogram the board. I did have this happen once quite a while ago & the nRFgo Studio Recover feature worked fine. Unfortunately, not this time.

Using the command line options gives the same basic errors as the Studio:

nrfjprog --recover:

Applying pin reset if debugger is not active. System off disabled until pin reset or power on reset is done. Halting device. ERROR: Cannot connect to the nRF51 device.

nrfjprog -p

Applying pin reset. ERROR: Cannot connect to the nRF51 device.

I'm using nRFgo Studio version 1.15.1.2691.

Help?
