ssh to it, and run firstboot, it'll reset the device.
you could also try to uninstall the theme/package, using opkg.

Meaning that the command " first boot" will reset everything on the router? Rite?

yes it will reset it, just as i said.

root@OpenWrt0:~# opkg
opkg must have one sub-command argument
usage: opkg [options...] sub-command [arguments...]
where sub-command is one of:

Package Manipulation:
        update                  Update list of available packages
        upgrade <pkgs>          Upgrade packages
        install <pkgs>          Install package(s)
        configure <pkgs>        Configure unpacked package(s)
        remove <pkgs|regexp>    Remove package(s)
        flag <flag> <pkgs>      Flag package(s)
        <flag>=hold|noprune|user|ok|installed|unpacked (one per invocation)

opkg remove package name

Example -

opkg remove kmod-nf-ipt6

If you don't remember the package name...

opkg list-installed
