Logged in fine for me using my pl2303 based ttl level adapter. Definitely try another serial adapter chip. ch341 = garbage! Get a pl2303 or FTDI. (Try to buy real and not China-fakes) Also double check the obvious stuff like connection, cables, etc.

I got into uboot too after rebooting. Interesting stuff. I guess I can recover this way if I fk up my device now.
I am in the process of dd copying my sdcard so that I have a backup. I can also then inspect the filesystem.
