You need a bootloader and an nfi file to flash. Here are the links for the DM800HD with the A8P sim

https://openpli.org/download/dreambox/DM800+SE+HD.Turn on your receiver with the power cord and at the same time hold down the power button on the receiver until you get the ip address.Type ip with lcd screen in your browser best chrome if it doesn't work try another web browser. First insert bootloader and then step back and insert nfi from openpli. When the flash loads up to 100, press the reboot. If it doesn't work with any browser, you will need a dream up and service cable as well as drivers for the com port. You will have to do all this with windows 7 because the drivers are adapted for that operating system. I wish you good luck :)Link dont work
