I had contact D-link and they give good help with the special software that's needed to put new firmware into a bricked camera and a link to latest firmware.
I didn't had time to test, of it will work out, i will give the results here.

for now i'm happy

The sollution that D-link me gave, doesn't work but i have it works again.
the camera works with a bootloader! how it works?
when the camera is bricked the ssid will change from DCS-935L-161C THE 161C are the last 4 digits of the MAC-ID of the device, so this is different on all camera's so when you see 161C you have to converted into the last 4 digits of your device.
In case of bricked camera: the SSID will change into rescue-161C (without encryption) because of the rescue in the ssid you will know that the camera is bricked so without a firmware.
So you have to start with the built-in bootloader, when you connected wifi with the camera (dhcp), the website of the bootloader wil be 192.168.1.30
so in the browser you can browse to the firmware file and start the process, the update wil take at least 140 sec when the leds are out, the firmware is ready, unplug the power and replug it, after a wile you see the SSID (With encryption) the same as written on the device, and you can follow the config as a new device. login naam "admin" and leave password blank. So i hope that can help this other people.
Thanks to for helping me out,
