PCA10028 completely bricked, jlink unrecognized

[Tom Liu]

Hi everyone,

                   sadly my nRF51-DK boards seems to be terribly bricked.

During firmware update nRFgo Studio (on Windows) stopped responding.

I can't enter bootloader mode on the atmel chip that contains the J-Link interface.

I tried to hold down the "IF BOOT/RESET" button on the DK while switching it on,

and it don't show up as an external disk named "BOOTLOADER".

Regards
