This is the complete setup for extreme.
It's fairly easy but there is a sequence of event that must be used.
First you need Loader program in your computer.
Next get the latest Bin.
What is best is to set-up a folder so You can have the loader and any related files at the same place. No searching.
If you have the latest
BIN it needs to be Unzip and extract the file named PMG to your folder.
Next it's recommend that you turn off the receiver from the back and bring to your computer if you can, to avoid confusion at the beginning.
Next Make SURE power is OFF from the back switch, then connect the Null cable at the back of receiver and then into the USB adaptor or directly into the Serial port of computer.
NOTE: If you use the USB adaptor you must have first installed the software for the adaptor.
Now start the Loader program,click on Open Files, this should open a Window and it's a matter of finding the folder where you put your program and files, chose the file named PMG and click on it. It will appear in Main software with the path where it is located.
Now at this time click on PC/
STB and turn power on to your receiver from the BACK switch.
It should start downloading, it will take a few minutes and do NOT TOUCH ANYTHING, WAIT RIGHT TO THE END.
On some set-up it will show download complete on the computer and when you click on OK it does send a few more things to the receiver. Watch the window of the receiver and every time you hit OK (as it may come back a few times)
You better do it a few times and ensuring that you are completely done than locking-up your receiver.
Once completely done. SHUT OFF receiver at BACK, unplug from computer at USB and remove null cable.
Re-install receiver always making sure it's OFF before connecting anything to it.
Turn on your receiver and wait a few minutes for it to auto roll.
Hope this helps you.
