Could you verify if you can recover the chip ? In the second image it seem you managed to get to recover the chip and can program the firmware.

The error on the second image show that you are programming into protected area. This usually happens when you flash an older version of the softdevice. Make sure you have latest version of the material:

• nRFGo Studio v1.15.1
• Softdevice version 5.2.0
• SDK version 4.3

If you still couldn't recover, you can try to use the nrfjprog.exe tool. You can open commandline and type:

nrfjprog --recover

You should be able to recover the chip. If error occurs, please take a screenshot.

I would suggest you to follow the quick start guide in the nRF51822 Evaluation Kit Userguide to make sure everything work fine.
