Title: PPK2 Not Recognized After Accidentally Programming BLE Firmware

[Usha]

Hello,

I accidentally programmed BLE firmware onto my Power Profiler Kit 2 (PPK2), and now the device is not recognized. Here's what happened:

1. I first opened the NRF BLE software and connected to the PPK2.
2. I mistakenly selected the PPK2 device in the NRF BLE software.
3. A pop-up appeared asking to program the device, and I clicked "Program."
4. After this, I opened NRF Connect for Desktop, but the PPK2 port was no longer recognized.

• Symptoms:

  • The PPK2 does not show up as a USB device or port.
  • It is not detected in the Power Profiler software.

I believe the BLE firmware overwrote the original PPK2 firmware. Is there a way to re-flash the PPK2 with its original firmware to restore its functionality?

Thank you for your support!

Hi,

 

It should be possible to manually enter bootloader mode on the ppk2 device. Could you try to follow the guide here given by my colleague Øyvind?
