Hi,
I have downloaded omv_3.0.51_rpi2_rpi3 image (and also tried with omv_3.0.41_rpi2_rpi3) from Sourceforge.
I run these commands on my Ubuntu box:
gunzip omv_3.0.41_rpi2_rpi3.img.gz
sudo dd bs=4M if=omv_3.0.41_rpi2_rpi3.img of=/dev/sdb
Then I insert SD card to my RPi and run it. The problem is, it seems it does start to boot, but there is no signal on the screen. I can see an IP assigned to RPi on my Mikrotik router, but cannot ping it and nmap shows all ports are closed.
What am I doing wrong? Probably there is some stupid error, but I cannot find a solution. BTW, I tried to install original Raspbian Jessie, and it is working nice.
