Hi there,
I've got a promblem with my Tinker Board S. It has a TinkerOS on it, but I don't know where exactly it is installed (whether it is eMMC or external SD card). The problem is that I can't install a new OS on it. When I connect the SBC to my computer with the SD card plugged in, it is seen as Linux UMS device with the size of ~16 Gb. But my SD card is 64 Gb. If I flash it w/etcher or Win32 Disk Imager, it doesn't help. The TinkerOS' previous version and all its data is still there. If I connect it without SD card, it is seen as Unknown Device. Trying to turn it on in this way gives practically the same result: the red LED is shining, but there is no signal on HDMI. Jumper changes don't help. What can I do to solve this problem?
It might be of your interest to read this and its relevant discussion.

It advisable to use something that is able to read the extfs. First is linux OS or a program like ext2fsd. So you may understand what is written on the TBS.
