Help with a xbmc venz 3 that I've messed up

  • New to android boxes in general and was messing around with this old xbmc venz 3 android box to try and perhaps flash a different os (like linux or something). I was messing around in the settings and changed the runtime from something to art i think? Now when it starts, it is unable to get off from the start up screen and there is pretty much 0 documentation regarding this android box. Thought my best chances would be to ask reddit

    P.S. if theres a way to flash a os (idk maybe linux or something) even while stuck in this state, plz lmk since that is essentially the end goal i wanted for this device as I wanted to turn it into a plex server or something similar
