topic into English using translate.google.com, probably you would find it easier to translate it directly into German:

Select your. Corresponding dl. Then select the firmware file in the firmware components (you can use any firmware, but I recommend that you use the package). Do not worry about the other fields.
6.agora we have run with the button burning system. Note that two lines appeared quickly (it's probably not possible to read) and then two more.
The first line relates program preparation
The second refers to the memory of Dingoo cleaning (yes, it will be blank in this step)
The third line refers to writing the new configuration of the Dingoo, if all goes well the screen will light up showing the damned being updated.
The fourth line is to tell us that everything went well.
Unplug the Dingoo and enjoy
