How to Lock a Device after load file successfully.

Instead of using the loadbin command use loadfile.

loadfile s110_nrf51822_7.0.0_softdevice.hex loadfile app_mac.hex

Notice that you don't include any address when loading a hex file. This comes to the problem you were seeing: a .hex file has more info than just binary data to be loaded into memory. Info like the addresses where data should be loaded etc.. So you don't need to specify an address offset for hex files when programming them because this info. is included in the hex file.

In case 1 you were reading back memory from the device so you would read back a binary file (just pure data). And thats why this worked. (even though you then saved it as a .hex file extension).

In case 2 and 3 you actually had a hex file (Intel hex) which has more info and this probably screwed up JLink's loadbin as it was expecting binary data and got something else. (I guess Jlink didnt check that this was actually a .bin file)
