I am a novice. I flashed a SNAOSHOT version by mistake. Now I cannot access Luci and when I connect via SSH, it asked the password which is not what I set before. Can anybody help? Thank you so much in advance.

(mount root and set new passwd, or do any of full resets)
Password is empty, just hit Enter.
