Please be sure for your bootloader version ( you can get it from browser , in this expemple bootloader is #57) Dm800 hd and dm800 hd se don’t have the same image Image for original dreambox is not the same for clone one ( you can broke your box ) *You need the image file you want to flash. Image files have the extension *.nfi. You can’t flash other images like *.img files. Don’t try it – it won’t work. *You need either a DHCP server, a configured bootloader or a serial cable and a terminal program like HyperTerm. *You need a browser, and a network cable. If you connect the Dreambox directly to the PC, you need a cross cable, if you connect trough a switch/hub/router you need a normal (non-cross) cable. To flash a new image, you can use the second stage loader. It must be present and not broken. The following steps assume you have a DHCP server. If you don’t have one, you have to setup an IP address in the bootloader’s serial setup: (same like DM8000) - Power down the Dreambox, either using “shutdown” and by removing the power connector. Standby is not enough! - (1.) Press and hold the power button. Replug the power connector into the Dreambox. - (3.) A text “*** STOP ***” should appear. Now you can release the button. The bootloader entered the “waiting” mode. - (4.) Above the “*** STOP ***” text, there should appear an IP-address (four decimal values with a dot in between). If there appears the string “dhcp” instead, the box still searches for a DHCP server. Wait a bit. If it doesn’t change, something doesn’t work with the DHCP server. Check wether network cable is plugged in etc. If it just doesn’t work, set an IP using the serial terminal - Now, open a browser on your PC. (1.) enter in the address line “http://ip/” (where ip must be replaced with the value in the LCD). - (2.) on the bottom of the page, there’s a link called “firmware upgrade”. Click it. - On the next page, you can select the flash image you want to flash. be sure that it has the “.nfi” extension. You can’t flash other images (like .img)! - Click on “FLASH!” and wait. It might take some time to upload and flash the image. - Switch the box off again, and on again. The new image should be flashed and working.
