I didn't mention earlier but after I ran the update/upgrade commands I also manually updated the locale file. During the original setup I accidentally selected the wrong locale, I went into armbian config, deselected the wrong one and selected the correct one but the incorrect locale was still being referenced constantly. So I manually removed it from etc/default/locale. I thought this may have been a reason for it no longer booting and not the update/upgrade commands.
I'm just explaining that so you understand why I also tried update/upgrade with the x98h image. Turns out it wasn't me messing with the locale that stopped it booting as this image also will not boot now after apt-get update, apt-get upgrade.
This image originally booted ok and it seems the ethernet works better. Downloading from the commands listed above took about 20 seconds vs 30 minutes on the vontar image. But wifi/bluetooth still will not work. One other difference is when I select the bluetooth manager app it actually loaded whereas the vontar image would state something about a service not running. The app loaded but had no devices listed.
I'll see how I go with termux. The play store doesn't work on it but I was able to sideload a couple of apps.
