My WPA4220 was working perfectly and I decided to update the firmware. Since then the wifi has stopped working and the unit is unresponsive to the buttons on the device.

I can pair the device using the app, but it doesn't show wifi on the app and it is acting like my PA4010. No option to upgrade firmware, or toggle wifi.

The device is working with LAN cable. 

I did the same upgrade to my other wpa4220 and that is working perfectly. 

Any ideas, can I redo the firmware? Thanks
