Flashing with SD Card

Create a partition with an ext or FAT file system labeled as "DREAMFLASH" on the USB device. Then copy the imagefile to the device and rename it, if necessary, to dreambox-image-dm520.tar.xz (for DM520HD, and choose the right image for the box naturally), then plugin the device and reboot the dreambox.

Hi
First of all thanks for the precious help you offered me
I already solved the problem.
It was difficult because I couldn't connect the box through the internet port to be able to put an image.
But I will explain how I did it.
I had tried everything to be able to start with it by the recovery system, but the box did not obey it was always with the front button, in red and the LEDs of the internet port flashing.
So I did this: I left her out of energy overnight.
The next day, I turned it on by pressing the red button and turning it on to power to start recovery.
To my amazement it took off and was in a way to insert a new image.
It's working with a Gemini 4 image.
Thank you for your assistance.

Great news, well done !
