Looks like the jffs2 overlay is corrupt, which factory reset should be able to fix.
Try viewing and capturing a log while holding the reset button down and keeping it held until it says something about factory reset or redoing the jffs2 overlay.
Right now, the greatest likelihood is that such a factory reset hasn’t been successfully triggered, rather than that it failed to solve the problem. There are probably more drastic things that could be done, but first make sure the factory reset process has actually tried to run.
Sorry, had missed in that log that the squashfs is also corrupt, the TFTP procedure linked below is what you want to do
