--- FAILED ---
The file authentication module continues to
authenticate any new signature files
downloaded with the OS files.
When the signature file authentication routine
starts, the status display informs you of the
progress of the authentication process.
If file authentication succeeds for a specific
signature file, the “
AUTHENTIC
” message is
displayed directly below the filename of the
signature file. If file authentication fails for a
specific signature file, the “
FAILED
” message
is displayed for five seconds below the
filename and the device beeps three times,
allowing you to note which signature file failed
to authenticate. The authentication process
proceeds to the next signature file until all
signature files are validated.
When all new signature files are
authenticated, the device restarts, and the
application specified in the *GO variable or the
default application in Group 1 executes and
starts running on the device.

If the downloaded application successfully
authenticates, the corresponding application
prompt or logo is displayed upon restart.
The device can now process transactions.
Note:
The message
DOWNLOAD NEEDED
appears if:
•
The *GO variable is not set.
•
*GO does not specify that an application is
present.
•
The application did not authenticate (invalid
or missing *.p7s file).
•
The application uses shared libraries that
are missing or were not authenticated
(invalid or missing *.p7s files).
If one or more executables in the application
fail to successfully authenticate, the
application may not run. If the application
attempts to access an unauthenticated
executable or library, it may crash. Repeat the
Direct Operating System Download Procedure
using the correct certificates and signature
files.
