Hello i have a NVR4208 - some month ago i upgraded to v4, but the Motion Detecting didn't work, therefore i tried today to downgrade - downloaded the firmware and update it in the web browser.
After this nothing worked, if the NVR boots up, i can try to login in, and the NVR blocks, after some time it reboots, i tried to press the reset Button inside at booting.
But nothing changed.
At the moment the NVR boots up, i see the 9 rectangle with the cameras and the Montior shuts off, after some time the NVR reboots.
I tried it with and without the HDD - is there a possibility to flash the firmware somehow?
