Installation process:
OBB files contain additional game data that some apps require to function properly. Not all mods include OBB files, but when they do, follow these steps:
What you need:
The OBB file(s)
The MOD APK file
A file manager app
Steps to follow:
Download the OBB file(s) and MOD APK.
If OBB is in a ZIP file, extract it.
Using your file manager, go to: Android/obb/[package code]
Example: For CSR Racing 2, go to Android/obb/com.naturalmotion.customstreetracer2
Move the OBB file(s) to this folder.
Install the MOD APK
Launch the app and enjoy!
Note: If you get an error saying the OBB file cannot be copied, try a different file manager app or transfer the file using a PC or Mac.
Starting with Android 11, Google restricted access to the Android/obb and Android/data folders. The easiest workaround is to use a file manager app, but some work better than others, so you may need to try a few.
If your device is rooted, you can access these folders without restrictions.
You can also connect your phone to a PC or Mac with a USB cable and access the obb and data folders through the computer's file explorer.

Unsigned APKs require rooted devices with signature verification patches. Most of the time these are not provided since they are only available on specific setups.
Requirements:
Rooted device
Signature verification disabled (using tools like Lucky Patcher or Xposed)
Installation:
Download the unsigned MOD APK
Install directly over the original app (no uninstall needed)
Launch and enjoy
Note: If installation fails, your signature patch isn't working correctly.
Unlike signed mods, unsigned versions allow:
Google login without issues
Facebook login with the app installed
In-app purchases that function normally
