Power Profile Kit2 reflash the firmware

[chapman]

Hi

My PPK2 was accidentally flashed by the nRFConnect's "Bluetooth Low Energy" app and then it bricked. 

PPK2 then could not be detected by "Power Profiler", even  "Programmer" could not detect it. 

I have also tried to  use JTAG on the PPK2 connected via the DEBUG OUT of a NRF52840-DK, but it seems it could not be flashed through it and get the following error:

08:56:09.301

Recovering Application core

08:56:09.302

Recovering Application core 0%

08:56:29.443

Failed to recovering application core core. Error: [object Object], message: Batch task recover failed, [jlink] RECOVER_FAILED

08:56:29.685

Error: Failed with exit code 1. One or more batch tasks failed: - [jlink] RECOVER_FAILED, code: Nrfjlink. Message: Batch task recover failed, [jlink] RECOVER_FAILED.

What could you advise to recover the PPK2?

Thank you.

Try the following should still work:  RE: PPK2 not turning on

Disconnect all other nordic devices from the computer, turn off the kit and remove it from the plastic by removing the four screws. Insert USB to J2 (USB DATA/POWER). Short a connection between GND (e.g on the four pin power output header) to TP34 on the PPK2. While holding the jumper cable, turn the kit on and remove the jumper. Now the PPK2 should be in bootloader again.

Open the PPK app, and select the device which is now just a serial number.
