Downloaded a MOD APK but it’s in .apks format and won’t install like a regular APK?

Don’t worry. You just need SAI (Split APKs Installer) — a free tool that lets you install .apks, .apkm, and split APK bundles easily.

In this guide, we’ll show you step-by-step how to install any .apks file safely using SAI on any Android device in 2025.

What Is a .apks File?

A .apks file is not a single APK — it’s a bundle of multiple APKs (called split APKs). These are used by Google Play and modern Android apps to save space and target specific devices.

You can’t install .apks just by tapping them — you need a bundle installer, like SAI.

Step-by-Step: How to Use SAI (Split APKs Installer)

Step 1: Download & Install SAI

Avoid shady websites — download from official sources for safety.

Step 2: Give Required Permissions

  • Open SAI
  • Tap Settings
  • Enable “Sign APK before installing” (optional but recommended)
  • Grant “Install Unknown Apps” permission

Step 3: Load the .apks File

  1. Tap “Install APKs”
  2. Select “File Picker”
  3. Navigate to your .apks or .apkm file
  4. Tap “Select”

Step 4: Install the Bundle

  • SAI will load all split APK components
  • Tap Install
  • Allow installation when prompted
  • Done! Your app is ready to use 🎉

If You See Errors (Fixes)

Error: “App Not Installed”

  • Uninstall existing version of the app first
  • Make sure Android version is compatible
  • Re-download .apks from namoapk.com

Error: “Permission Denied”

  • Go to Settings > Apps > SAI > Install Unknown Apps > Allow
  • Or use the “Legacy Installer” option in SAI settings

Tips for Installing MOD .APKS Safely

  • Always uninstall the Play Store version first
  • Avoid renaming file extensions
  • Use a trusted file explorer (like ZArchiver) to manage files
  • Scan files with VirusTotal before installing
  • Only download from trusted sources like namoapk.com

Conclusion

With SAI, you can easily install .apks or .apkm MOD APKs in just a few taps.
It’s the safest way to install split APK bundles without root access.
