So here is what I did. I downloaded the zip file. It contained only 1 .fir file which I assume is the firmware. I turned off my Air and then pulled out the WLAN usb and put in the USB stick that is formatted 2 gb FAT and had the .fir file on it. I connected it by ethernet cable and powered it on. I did not hear any start up chimes but I saw the green on indicator light. I left it alone all night. This morning I tried to connect to it using my AxiomAir app on my iphone and could not. I turned off the Air and turned it back on after waiting 5 seconds. I left it alone for an hour. I did not hear any startup chimes and I cannot connect to it using my iphone app.
It looks like my Air is dead
What do I do now?
