LEDs snippet on WBMR-HP-G300H not working for .v19.07.3

Installing and Using OpenWrt
1

I have installed v19.07.3 on my WBMR-HP-G300H (in 3 steps: from Buffalo stock firmware, then DD-WRT, then OpenWRT).
It seems to be working all right for now, but the LEDs are off all of them but the power one.

This is the snippet I put on "/etc/config/system", extracted from WiKi OpenWRT LEDs snippet :

config led
    option default '0'
    option name 'power'
    option sysfs 'soc:green:power'
    option trigger 'default-on'

config led
    option default '0'
    option name 'power2'
    option sysfs 'soc:red:power'
    option trigger 'none'

config led
    option default '0'
    option name 'wifi'
    option sysfs 'soc:green:wlan'
    option trigger 'phy0tpt'

config led
    option default '0'
    option name 'security'
    option sysfs 'soc:red:security'
    option trigger 'phy0tpt'

config led
    option default '0'
    option name 'dsl'
    option sysfs 'soc:green:adsl'
    option trigger 'netdev'
    option dev 'nas0'
    option mode 'link tx rx'

config led
    option default '0'
    option name 'online'
    option sysfs 'soc:green:internet'
    option trigger 'none'

config led
    option default '0'
    option name 'online2'
    option sysfs 'soc:red:internet'
    option trigger 'netdev'
    option dev 'nas0'
    option mode 'tx rx'

config led
    option default '0'
    option name 'usb'
    option sysfs 'soc:green:usb'
    option trigger 'default-on'

config led
    option default '0'
    option name 'movie'
    option sysfs 'soc:blue:movie'
    option trigger 'timer'
    option delayon '1000'
    option delayoff '1000'

Any ideas?

I was walked through this in this thread:

If you have LuCi, there is a config tab for the leds and from it you can control the LEDs. This includes simply turning them on and off or making them respond to different triggers..

Another suggestion is to look at devices using the same chipset - the gpio's are etched in silicon.
