How to Install the WR777 APK

Open the completed package from Chrome Downloads, review Android’s source prompt and grant only the permission required for this installation.

Download WR777 APK

Installation steps

Install from Chrome Downloads

Finish the package download

Wait until Chrome shows the download as complete. Do not try to open a partial file.

Open Chrome Downloads

Use Chrome’s menu and choose Downloads, then select the package you intentionally requested.

Review the unknown-app prompt

Android may ask whether Chrome can install apps from this source. The permission is specific to the browser.

Allow this installation

Enable the source permission only for the current task, then return to the package prompt.

Open the installed app

When Android finishes, open WR777 and follow the current on-screen flow inside the app.

After installation

Keep Play Protect and other device protections enabled. Installing an APK should not require turning off wider Android security. If the device reports a package conflict, signature mismatch or blocked installation, stop repeating the same step and use the troubleshooting guide.

Source permission on different Android phones

Menu wording varies by Android version and phone maker. Look for an option such as “Install unknown apps” for Chrome rather than a broad device-wide setting. You can turn that Chrome permission off again after the installation finishes.
