Important note before you start:
All this stuff is for people with experience on electronics you can use it at your own risk.
1) The Jtag cable should not be longer than 12". Best to keep it as short as possible.
2) Before you decide to upgrade your receiver firmware, please do a backup of your original firmware
3) Your receiver flash rom can be erase and program again and again.
4) Loading the wrong file into your receiver will not damage your flash rom but only render your
receiver non-functioning. So if you happen to load the wrong file to your receiver, you can use
Jtag to reprogram it.
5) If Jtag can read your flash rom, then the flash rom is fine. If not, then is corrupted.
6) It is always safer to use Jtag to upgrade your receiver than to use Null modem cable.
7) When you use Null Modem cable to load firmware into your receiver, even a slight error on the
serial port or cable will affect the transfer of file from your computer to the receiver.
