There is a way you can type it in manually on the box using dreamexplorer. But as above it has to be done after flashing the build otherwise it'll overwrite it.
You can't sell items in this thread.I have a good working Dreambox 500c with lots of accessories.
The interested party must pay the onward postage only.
