and a couple from Armbian 5.44_S812...... both debian and Ubuntu
plus LibreELEC-S802.MXIII-1G.arm-7.0.2-2-devel.img.gz,
since it seemed to be proper box
most go to the google.tv screen go black for a bit then get stuck in pixelated screen (for lack of a better term), some just seem to go to the google.tv splash screen then wait longer than usual before booting back to MBox and android
Libreelec actually gets to a text screen
... press anykey or wait 120 sec to abort ...
wait the 2 mins and then get something about READ ONLY file system blah blah blah this box is permanently ... something in the order of bricked, can't recall exact verbage, but if I reboot boots back into mbox with no issue
