Laptop wireless hard blocked - hardware key does not toggle state

Question

hello,
this is my 3d arch install. i kept notes, and followed them exactly and this time i've ran into an issue i just cannot seem to debug myself.
this laptop is the hp envy 4 1130us. i also have the hp envy 6t-1000 with arch installed and this is not a problem at all for that version of the computer (one is my personal the other is my work machine).
after installing the base system i installed the wifi related packages:
pacman -S wpa_supplicant iw wireless_tools networkmanager network_manager_applet gnome_keyring
i enabled the network manager
systemctl enable NetworkManager.service
disabled dhcp (enabled from install)
systemctl stop dhcpcd.service
systemctl disable dhcpcd.service
enabled the wpa toolkit
systemctl enable wpa_supplication
add my user to the network group
gpasswd -a xero network
turn off the network interface controllers
ip link set down eno1
ip link set down wlo1
start the supplicant
systemctl start wpa_supplicant
start the network manager
systemctl start NetworkManager.service
reboot
after that the wired internet work perfect fine. the network manager applet detects the network and does it's thing. i configured and tested vpn as well, and it is also working as expected.
but then i pressed the hardware wifi switch (F12 key) and nothing happened. i pressed it a few more times, rebooted, tried again, tried during the bios/post test, etc. i simply cannot disable the hardware lock on the wireless.
so i went hunting on the wiki and here in the forums. nothing has worked. since, this was a fresh install last night i actually wiped the drive and tried the install again hoping i did something wrong, but with no avail. here's the debug messages:

Hard blocked: yes
so based on some of the output it looks like RFKILL is blocking it during the boot process. i tried to unblock it via the unblock all command, but that's only soft blocks. i'm really not sure what to try next, so i'm asking for help (before i throw my laptop out the window).
thank you in advance for any advice

Answer 1

yeah,
i was thinking that recompiling each kernel would be a huge hassle as well.
so i just booted 2 live usb disks.
the 1st, the arch installer - the wifi was still hard blocked.
the 2nd, debian / crunchbang. what's odd, is that in debian the wifi key light is while (enabled) but it's still blocked. if the press the button it turns amber (disabled), if i press it again it turns white again and is actually enabled.
it almost seems like arch is not "catching" the action keypress. the keyboard backlight key works out of the box, and so does the screen brightness keys. but i run xfce4-volumed to control the volume related keys. is there anyway to emulate the hardware keypress to even see if that's the issue?
-----------------[update]-----------------
so i decided to try and enable the rfkill unblock all service:
systemctl enable [email protected]
that alone didn't work, but...  i booted into another os, enabled wifi, then hard powered off the laptop. when i rebooted into arch it seems to work now. it's a really hacky work-around. but i'll take it. i'd really like a proper solution, but it works for now i guess.
