Previously I had to reset my password. I found an article on how to edit cmdline.txt and followed the directions and it worked. Later, I tried to install KODI on RP3 running Raspian Jessie. It stopped and froze the machine. All I could do was power down and then up. It then demanded a password. I entered it, the screen flashed black and then returned to the same password prompt. Thinking I had the wrong password I tried several others. It behaved differently. After checking some records I believed I had the correct password. I re-tried the reset process. It gave me the same result and did not allow me to set-up the "pi" user as the article said it would. I think I may be out of space on the card. Another thing - when I place the card in my Windows 10 PC it shows me multiple drives - not just the one extra one. They seem to have different things on them. I believe I changed all occurrences of cmdline.txt in each of the roots of those drives. A newbie to Linux... thoughts?
