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.</p> <p>Open the PPK app, and select the device which is now just a serial number.<span></span></p> <p>When selecting it, the user will be prompted to program the application and it should now be working again.</p> <p>Best Regards,</p> <p>Swathy</p><div style="clear:both;"></div>
