I recently obtained two 301-010 receivers with a legacy twin from a previous owner. I hooked up the dish, ran a check switch and I am receiving a good signal. I followed the instructions for upgrading the system software but it does not seem to work. The receivers have been disconnected for some time and have version p128 software. Any suggestions. Also, will Dish Network allow me to activate a previously activated receiver? Also, one receiver does not have the smart card. Does this mean it is useless, or can I purchase a new card for a receiver that was activated under someone else? Thank you.
