I had a USB thumbdrive set up and formatted for the Mi box. I removed for a few minutes to try something, and now that I've plugged it back in, I can't install anything onto it. It recognizes is as storage from what I can tell, and I can open all the app that I previously installed. I can't however, install anything new. It just states that I don't have enough storage space. It's trying to install internally i'm assuming, the usb still has 49 gig left. Is there a way I can specify where to store new files?
IIRC, max size of USB drive for Amlogic S905X-H devices is 32GB.
Try to repartition drive into 2 with acceptable sizes. Perform backup first, naturally.
Good luck
