[nRF52832]After I erased it ceased to connect

Daisuke____

I use SMK BTS-04 using nrf 52832.
After doing "Flash Tab -> Erase" of Keil's development environment, it became impossible to connect at all.
I tried using nRF 5x Command Line Tools (nrfjprog.exe), but the following log will appear and an error will result.
Can you tell me the possible causes?
Also, please listen to any necessary information.

Default setting contents of "nrfjprog.ini"
  Family = NRF 52
  Clockspeed = 200

    -102 means that you are executing nrfjprog in a directory where it does not have write permissions to create a log. 
    -1 error should not have happened. But I see that you are using very old version of nrfjprog. The current version is 9.7.2 with a lot of fixes. Can you please update this and retry. You can find the latest here.

    If this does not work, then most probably your device is bricked. But just doing an erase from the Keil will not brick the device. There must be something that might have happened like the device loosing power in the middle of erase or something like that.

    thank you for your answer.

    I tried using nrfjprog 9.7.2 and Jlink 6.30h, but a similar error occurred.
    I wrote the settings and log contents at that time as below.
