Got the device (orange pi one) a couple weeks ago and have had to wait a while getting all these extra parts.

I got my new sandisk 16gb sdcard today and tried flashing h3droid onto it with etcher. Completed fine.

I plugged it into a usb port with the cable provided (not using a mains one but I should at least get some output right?)

I needed a converter for my monitor 24 + 5 dvi because it didn't have hdmi connector.

So I plug it into the pi.

I press the on button. The red light comes on for a while then flashes, then a green and red then just green then off. Don't know the combination exactly.

But I turn the monitor on and off and nothing.

Is the screen not compatible or something else? hard to tell wtf is going on...please advise.

I will try with an arch image later to see if that changes. The flashing lights were promising though so I am thinking maybe it isn't a faulty board in that case?

I know that it isn't advised to use the usb cable but that wouldnt stop it from showing any kind of screen output would it since the screen has its own power? I thought it was just power issues so maybe it would be unstable but would work to a certain extent. Ie why would they ship it with that cable if it didnt work at least somewhat?

I know with Armbian Linux I had to use an HDTV first to get the display so I could log in and run h3disp.  There is an -d option with that utility that specifies a DVI converter.  I'm guessing this turns off the HDMI handshaking most HDMI TVs use and forces the OPI to use the specified resolution whether the display likes it or not.

So what resolution your monitor is? Usually Orange pi suppose to support 720p resolution, maybe you could first have a check and modify it.
Good luck!

I've been debating whether to buy a small hdmi monitor although they cost more than I paid for the device. I think I will persevere and try my other routes first and only do that once I have exhaused my other lines of inquiry. I hadn't worked on it since making the post as I had alot of work setting up a remote server (unrelated) but got that going now so can start looking into this again.

Edit: I checked with 'adb devices' command as well as nmap and the device didn't show so I guess something is wrong but no idea to know without visuals what it is.
