Update: Found an old Phison USB stick, flashed the PID/VID in a Windows XP VM and restored the original img. My DS booted finally from the USB stick, and once I've got terminal access I restored the img to the DOM directy on the Synology. Everything works again now, thanks for the hints : ) Admittedly the flash tools are indeed a bit shady but got the job done.

Thank you for the usb pinout! I have a ds415+ on which I once overwrote the synoboot flash over serial (was a bad idea) and would like to restore the original image. Luckily I've dumped an image with dd before breaking it. I assume the connector is the same as the ds412, and I'm trying to connect the 4 pins as shown in your pinout to my computers usb2 header, but it keeps failing to recognize the device. Does the AVSS +5V need to be connected to something? dmesg keep telling the device is not responding.

Are there other known models to have the phison or other configurable chip in it? Thanks
