Help "fastboot -l devices" returns nothing

Hello

I'm a newbie trying to learn about what alternative firmware I could use to upgrade my Nexus Galaxy from Android 4.2.1.

After connecting the phone to my Windows PC with a USB cable, I followed this video on YouTube to start the Nexus in Fastboot mode, clicked on the right button to proceed, and once Android was up and running, ran this from Windows...

Code: 
[c:\Android-adb]fastboot.exe -l devices

... which returns nothing.

Any idea why, and what to do?

FWIW, the phone is also running an ADB server since it's used by the MyPhoneExplorer application to sync Outlook with Android.

Thank you.

I'd suggest posting this in the root section of the forum. Perhaps a mod will move this thread for you....
 
It looks like faulty drivers: Windows complains with "Device driver software was not successfully installed".

Apparently, we need two drivers: One for ADB, and the other for Fastboot.

Does someone know where the official Samsung drivers can be found?

Thank you.
 
Just curious? Have you installed the Java SDK package? You need this to enable proper communication together with the correct drivers, or you could use this free tool from mskip, a developer over at XDA. I have used this without issue myself and it is really straight forward and easy to use. You'll find it here http://forum.xda-developers.com/showthread.php?t=1392310.

Beside your command is incorrect anyway; when you have a cmd in windows the command should be '>fastboot devices'.
