"download not requested" is a cable or com port issue.
You need a "null modem" cable the "RS232 serial" is identical
to look at but won't work.
But lets assume you have got the right one
First, if you need to use your USB converter lead, find a driver the "prolific" driver usually work
Welcome to Prolific (sorry forgot how to post a link)
Then find the com port number you are using on your computer.
Go into device manager on your computer look up properties on the com port you are using and change
the baud rate (bits per sec) to
115200
then wire up the box and computer and use loader
to load firmware.
note the USB convertor lead don't normally give a very good connection
I had to give mine a couple of wiggles where it connects to the null modem cable to get it to work. It is better if you can plug the null modem straight between box and computer but on newer computers you will need the USB convertor lead.
The scrolling is because it is flashed with old firmware reflash with 24/04/2011
its in the download section on this site, make sure you are flashing with A780 firmware
and not A750 as they both have the same date and it will be fine.
Let us know how you get on
