[Request] ASUS N46VZ bios unlock

[kimyu92]

Asus N46VZ has the same specs and belongs to N56VZ and N76VZ variants

So,
Im facing a serious problem of upgrading my wifi card and I figured out it requires me to tape pin 20 of my wireless card
in order to allow my laptop to detect the wireless card and even with that, it's not an easy process and the wireless signal sucks for some reasons.

Since no one gave any response over my thread [link]
Can any pro from this forum help me please..

Thank you!
