Fix wifi drep and reboot issue
Overwork wifi country code (1/2)

manipulating the country code value or wifi driver directly causes weird behaviours or even hard system crashes. Caused by bad
implementation from AOSP

using now a help value for users country code choice and using it like aosp then.
