I inadvertently flashed my PPKII while trying to flash a 52840 Dongle. Now my computer doesn't recognize the PPKII when I plug it into the USB (PPK does not light up). I've tried several different USB cables to no avail. On another thread I saw someone mention a ppk_v1_0_0.hex file--where can I get a copy and how do I flash to the PPK if it's not recognized by Windows
