Not able to update to v6.11

Not able to update to v6.11. Application, responds that current v5.26 is the latest version no need to update?

update = 5.25 to 5.26

upgrade= 5.26 to 6.x

Th routerboard only auto-update, the last update for 5.x are 5.26
For upgrade to 6.x you must put “manually” new software on files folder and reboot

Thank you for the instructions it worked
