Hello,
 
for those of you who are struggling to license EB on an Android device using the "file" option (Option 1 as described here Enterprise Browser Licensing - Zebra Technologies TechDocs )
I found the small "glitch" that might help.
 
The documentation states - insert company name on the first line and license key on the second line.
But it's missing one key point - EOL has to be "LF" only.
This one (created in standard Notepad) does not work (obviously the license HEX key is random, not a valid one :-)

This one does  work - I have used Notepad++ to create this one

 
Hope that helps...
 
Also it might be usefull to include it in the standard documentation.
