You can do a firmware update by using this utility program, which transfers a firmware from the computer to the digital receiver through the serial connection (RS-232).
You can use this program immediately without an installation process.
This program is available on IRDETO-embedded models as follows:
* TF4000IR
* TF6400IR
* TF6400IRc
* TF7720HSIR
Hi, please can you explain to me how I can use this software for my Topfield 4000 Fi?! Thank you...
