I changed the screen with a new one. The new screen shows the apple logo, then the plugin a cable for restore perfectly fine. Then the update seemed to work and then when the firmware upgrade starts, the following error appears "The iPhone “iPhone” could not be restored. An unknown error occurred (9). 1304.FFFF". Is there anything I can do, thanks for any help!
See here for error 9→If you see error 9, 4005, 4013, or 4014 when you restore your iPhone, iPad, or iPod touch - Apple Support
Note that error 9 particularly is usually a hardware error, so if you replaced the screen yourself you might have broken something in the phone.
