3.1.4 ADB Mode Detection (Only for Phones that Can Properly Start) 
Connect the phone to the computer using the USB cable. Run the NFF detection tool compartner.exe. The 
automatic detection starts. The phone carries out the MMI test (you can skip this test by 
following the on-screen instructions) before the root test. The method for displaying test 
results is the same as that for displaying test results in fastboot mode.
