Well, personally, I would have used a different usb to install one of these pre alpha builds, & not touched the 8.2.2.3 build.
I think you need to start again, download the img.gz file & correct dtb, although it might be in the build. Also you need to bear in mind, that the remote control works in a completely different way. So, you might do best to use a keyboard for the initial configuration.
I’ll have a look, to see if I can find the relevant pages. But I do not have this device.
It looks like the device tree you need is in the image gxm_q201_1g.
If it boots up, you will then need to try to get the remote work, read, the links in this
