Got to the Rainbow Bridge. But prior to that we were having intermittent problems with connecting to Wifi (other devices were connecting fine so it was a Piper problem). After update, Piper worked enough for us to get to the Rainbow Bridge then the screen went black. We have followed past posts troubleshooting for blue to black screen; SD card reset; fully charged battery. No luck. Now the red and green lights on the Pi doesn't even turn on. Also in the battery pack, the small black plastic piece on the 1VA side seems loose (it moves around). Please advise. Thank you.
