must use the online upgrade way to burn, the concrete steps:
1 HDCP KEY cutting: will contain a number of KEY file cut into containing a single KEY
file to write.
(1)the first contains a number of KEY file ( file name is 421605-423143 ) copy to the burn tool
directory, run directory in HDCP_Key_20080114.exe file, select a KEY file ( 421605423143 ), the following chart:
( 2 ) By Key KEY Offset to set the cutting start position (i.e., from the first few KEY began
cutting ), Output # is to cut out a single KEY number ( recommended when cutting the
number of < 1000 ). If you select" Output Single File" will output a single KEY file ( this option
applies to a large KEY files ( such as 10000) cut into a smaller number of ( such as 1000)
KEY file ). If you want to cut into the containing a single KEY file, then uncheck the option.

( 1) To edit the configuration file, right click the burn tool folder in the hdcptool.bat, select
"Edit", using a text editor to open the file, set ser following numerical into serial debugging
tools port number ( in the operating system of the" device manager" -" port" view, different
computer port number may not be the same as the other ), keeping the default can be

( 4) writing is completed, unplug the burn line, change a machine inserted serial line, run
the hdcptool command to burn ( do not need to type hdcptool, requires only the cursor
prompt state by direction key" on" to make a type hdcptool command ). Write successful
KEY will be automatically deleted, to ensure that the same KEY won't be repeated
burning.
