- for me the serial consoles are disabled by default so I am blind half on the bootup.
- recovered passwords
ONTUSER: SUGAR2A041andadmin: 1234 - with SSH have limited access to console and shell need a dynamic password which I don't know
- Extracted a UBI partition from firmware use to config the router
