Hi Roger

Try to erase your program from the chip and the whole flash memory by opening nrfjprog.exe , which is a command line tool, and write the following:

nrfjprog --eraseall --family NRF51

If that does not work, try to recover your device with the following command:

nrfjprog --recover --family NRF51

You can get the latest nrfjprog.exe tool here for Windows. the nrfjprog.exe is part of the nrf command line tools install. This install is good for both 32-bit and 64-bit windows, even though the title currently says win-32
