How do I un-brick my nordic nrf mbed board? :(
Ok, so trying various above advice to work around the Yosemite USB issue, writing a compiled binary into the BOOTLOADER volume instead of the JLINK volume has bricked my nrf board - no flashing LD5, no USB volumes, whether I power on with or without the reset button held down.
Can anyone point to instructions about how I can re-flash the board or otherwise bring it back to life?

Step1) Determine if you have nRF51822-mkit, or nRF-DK, and get the appropriate mbed initialization file (bin, not hex).
- For mkit bin see: https://developer.mbed.org/platforms/Nordic-nRF51822/
- DK bin for mbed or jlink: http://www.nordicsemi.com/eng/Products/nRF51-DK/(language)/eng-GB
Step2) Have a look at: http://developer.mbed.org/questions/5222/nRF51822-mkit-Hex-vs-Bin/
