WiFi Country Code

An Xposed module to modify the Wi-Fi country code on Android devices, allowing you to bypass regional restrictions on Wi-Fi channels.

Features

• Override the Wi-Fi country code with any ISO 3166-1 alpha-2 code
• Enable/disable the hook at any time without rebooting the framework
• Quick select common country codes (US, CN, JP, GB, DE)
• Material Design 3 UI built with Jetpack Compose

Requirements

• Android 10 (API 29) or above
• Rooted device with an Xposed framework installed (e.g., LSPosed)
• Xposed API version 93+

Installation

1. Download the latest APK from Releases
2. Install the APK on your device
3. Enable the module in your Xposed framework manager
4. Select System Framework as the scope (the module will prompt this automatically)
5. Reboot your device

Usage

1. Open the app and navigate to the Configuration tab
2. Toggle Enable Hook to activate the module
3. Enter a two-letter country code (e.g., US, CN, JP, GB) or use the quick select buttons
4. Tap Save to apply the configuration
5. Reboot for the changes to take effect

How It Works

The module hooks into com.android.server.wifi.WifiCountryCode within system_server and overrides the following methods:

• setTelephonyCountryCode — intercepts the telephony country code and replaces it with the configured value
• pickCountryCode — returns the configured country code
• getCountryCode — returns the configured country code
• getCurrentDriverCountryCode — returns the configured country code

This effectively forces the Wi-Fi subsystem to operate under the specified country regulatory domain, unlocking Wi-Fi channels that may be restricted in your region.
