Hi Andy,

Have you tried recovering using nrfjprog? Open a cmd-window and input: nrfjprog --recover

If you have more than one JLink device connected, you will be prompted with a pop-up window to select the device.

Best regards Håkon

hi,Håkon,where is the nrfjprog located? tks!

After you install the nRF51 SDK you should be able to find nrfjprog at C:\Program Files (x86)\Nordic Semiconductor\nrf51\bin, this path is also added to the system's path so you can call nrfjprog from anywhere in the command prompt.
