How to Install MOD APK, XAPK & OBB on Android
Installing a MOD APK is easy once you know the 4 steps. This guide works for all Android versions (7.0 to 15) and covers APK, XAPK and OBB files.
1. Download the file
Tap Download on any mod page and wait for the countdown. You will be sent to MediaFire, MEGA, Google Drive or Pixeldrain — MODGRIND never asks for a password.
2. Allow unknown apps
On Android 8+, go to Settings → Apps → Special access → Install unknown apps and allow your browser or file manager. On older Android, enable Unknown sources in Security.
3. Install the APK (or XAPK)
- APK: Just tap the file and hit Install.
- XAPK / APKS: Use a split installer like SAI or XAPK Installer.
- OBB: Extract the ZIP and copy the folder to
Android/obb/<package>/(e.g.com.dvloper.granny).
4. Fix "App not installed"
This means the original Play Store version is still installed. Uninstall it first — mods use a different signature. Your save data will be lost, so back up if the game allows.
Common mistakes
- Not allowing unknown apps for the correct app (browser vs file manager).
- Installing OBB to wrong path — must be
Android/obb, notDownload. - Not enough storage — keep 1GB free.
FAQ
Do I need root?
No, 99% of mods work without root. Only a few marked "Root required" need Magisk.
Will I get banned?
Online games may detect mods. Use a second account for online features.
