I have the DS-7604 NVR with 3.0.9 firmware. I tried to upgrade to fw 3.0.15 from the web interface of the NVR, from a local USB stick on the NVR, from the iVMS4200 and always get the message "Upgrade failed. Not enough memory."
Then I tried the TFTP utility. When the NVR starts it responds for 3 pings to 192.0.0.64 but the TFTP server at 192.0.0.128 does not start any update transfer.
I do not get even the two beeps during boot up and the NVR screen is black.
Any help is appreciated.
