Motorola DROID4 (XT894) running Android 4.1.2

 Problem:
  - DROID4 originally configured for Verizon clients.
  - Verizon originally wanted USB tethering to be restricted to clients
    who had specific subscriptions.

  - for those who purchased the DROID4 on eBay and who are not Verizon
    clients, this means USB tethering is not available.


 Solution:
    1) "root" the DROID4.
    2) disable the "entitlement" check.

 Preparation on phone:

  - turn on "System Settings > Developer options"
	- set check-box for "USB debugging".


 Preparation on Mac OSX:

  - download and unpack "razr_blade_mac.zip"

  - [optional] download "razr_blade-x.sh"
	"razr_blade-x.sh" is a copy of "razr_blade.sh" but tweaked
	to display the commands as they are being executed, as well
	as showing the comments/messages.

  - connect phone to Mac with USB cable.

  - open a Terminal window and "cd" to where "razr_blade_mac.zip"
    was unpacked.


 See the *log.txt files for the commands and the results.
