My Pan-cam contains version 184.108.40.206. A pop-up now announces that a new firmware version is available. After tapping UPGRADE, the usual upgrading screen appears with a progress bar. The new firmware (220.127.116.11) appears to download and install successfully. However, upon completion, the “Update Firmware” screen appears indicating that 18.104.22.168 is still installed, and that 22.214.171.124 is available for download.
Restarting the camera has no effect - the download 126.96.36.199 firmware has vanished into the bit bucket somewhere.
