I'm possibly into a rare situation. I have a Nexus 7 LTE 2013 that suddenly stopped showing anything on the screen. It looks like turned off all the time, even the LED light does not turn on. I tried charging it in various ways and it did not help.
I contacted Asus and they asked me for the serial number, which I don't have. They said I can find this on the box, which I don't have either.
Using ADB, while N7 is connected to my Macbook Air, I did
adb devices and it shows up a device that is "offline". When issuing the command
adb get-serialno, it says unknown. It looks like the device is not dead but probably the screen is.
Is there any tool that can get me the serial number through command line?
I had an alarm set on the device. Today the alarm was fired and I heard the alarm ring from the device. I could only turn off the alarm by holding the power button.
