Try this-
1) turn off reciever
2) setup your computer to flash the Pansat with the latest factory .bin file
3) start the flash, and then quickly turn the pansat on.
4) do not interupt the process until the Pansat reboots fully
If this does not work you may need to JTAG your reciever to reload the factory boot files.
Good Luck!
BTW this is why I dont recommend flashing recievers unless the new files fix a known bug, or you are trying to remove hackware. Any interuptions of the flash process, or any corruption of the data being sent from the computer to the reciever, and you are looking at jtaging your reciever.
