How to Install APK + OBB Files on Android (2026 Guide)
If you've downloaded a mod game from UcheTechs — Dream League Soccer, First Touch Soccer, PES, GTA, or any other title — you've probably noticed it comes in two parts: an APK file and an OBB (data) file. Both are required for the game to run. Installing just the APK without the OBB is the #1 reason games crash on launch or get stuck on a loading screen.
This guide walks through the full process once, so you can bookmark it and refer back to it for every download instead of reading install steps repeated in every post.
What's the Difference Between APK and OBB?
- APK (Android Package) — the actual app installer. This is what puts the game icon on your phone.
- OBB (Opaque Binary Blob) — the game's data file: textures, audio, levels, player faces, stadium graphics, and so on. Games with high-quality graphics (like DLS or FTS) are too large to fit everything inside the APK alone, so the extra data ships separately as an OBB file.
Both files need to be in the right place before the game will open properly.
Before You Start
- Enable "Install from Unknown Sources." Since mod APKs don't come from the Google Play Store, Android blocks them by default.
- Go to Settings > Apps > Special Access > Install Unknown Apps
- Select the app you'll use to install (usually your File Manager or Browser)
- Toggle Allow from this source on
- Check your storage space. Most mod games need 300MB-2GB free, depending on the title. Check the download post for the exact size.
- Use a file manager app if your phone doesn't have one built in. Files by Google is a free, reliable option.
How to Install APK + OBB Files on Android (Step-by-Step, 2026)
Step 1: Download and Extract the Files
Download the APK and OBB from the game's UcheTechs post. They usually arrive as a single ZIP file.
- Open your file manager and locate the ZIP file, usually in your Downloads folder
- Tap the ZIP file and select Extract (or Unzip)
- You should now see two items: an
.apkfile and an.obbfile (sometimes inside a folder already named with the game's package ID)
Step 2: Install the APK
- Tap the
.apkfile - Tap Install when prompted
- Do not open the game yet once installation finishes — you still need to place the OBB file first, or it will crash or show a "downloading" error
Step 3: Move the OBB File to the Correct Folder
This is the step most people get wrong.
- Open your file manager and go to:
Android/obb/- Full path:
Internal Storage/Android/obb/
- Full path:
- Create a new folder here named exactly after the game's package name (this is usually given in the download post, e.g.
com.firsttouchgames.fts26)- If a folder with that name already exists from a previous install, use it — don't create a duplicate
- Move (don't copy) the
.obbfile into that folder - Confirm the file name inside matches what the game expects (check the download post — renaming it incorrectly is a common cause of failure)
Can't see the Android folder? Some phones hide it by default. Enable Show hidden files in your file manager's settings menu, usually under the three-dot menu in the top corner.
Step 4: Launch the Game
Open the game from your app drawer. It should load its data directly from the OBB file with no further downloading. First launch may take slightly longer while it verifies files — this is normal.
Troubleshooting Common Errors
| Problem | Likely Cause | Fix |
|---|---|---|
| "App not installed" | Old version of the same app already installed | Uninstall the old version first, then reinstall |
| Game stuck on loading screen | OBB file is missing or in the wrong folder | Re-check Step 3 — folder name must match the package name exactly |
| "There was a problem parsing the package" | Incomplete or corrupted download | Delete and re-download the ZIP file |
| Install blocked entirely | Unknown Sources not enabled | Revisit the "Before You Start" section above |
| Game asks to "verify" or download extra data on first launch | OBB file renamed incorrectly | Confirm the exact filename listed in the download post |
FAQ
Do I need to root my phone to install APK + OBB files? No. Rooting is not required for standard mod APK + OBB installs. It's only needed for advanced modifications like editing system files directly.
Why does my antivirus flag the APK? Mod APKs are unsigned by Google, so antivirus apps often flag them as "unknown" by default — this is a standard warning for any app outside the Play Store, not necessarily a sign of malware. Only download from sources you trust.
Can I move the OBB file with any file manager?
Yes, as long as it lets you navigate to and create folders inside Android/obb/. If your default file manager doesn't show this path, install Files by Google.
