To change the app's appearance, such as name, icon, theme, etc.
To change the app's behavior, such as settings, graphics, sounds, etc.
To add custom features, such as scripts, models, assets, etc.
To bypass some restrictions or limitations imposed by roblox or your device.
To have more fun and enjoyment with your games.
However, before you start modifying roblox APK file with apktool, you should be aware of the risks and limitations involved. We will discuss them later in this article. For now, let's see how to decompile and recompile roblox APK file with apktool.
How to decompile and recompile roblox APK file with apktool
The first step to modify roblox APK file with apktool is to decompile it into a folder that contains its resources, manifest, and smali code. To do this, you need to follow these steps:
Download the latest version of apktool from [here] and extract it into a folder of your choice.
Download the latest version of roblox APK file from any source of your choice (see above).
Rename the roblox APK file as "roblox.apk" and place it in the same folder where you extracted apktool .jar file.
Open a command prompt window (cmd) and navigate to the folder where you placed the apktool.jar and roblox.apk files.
Type the following command and press enter:
java -jar apktool.jar d roblox.apk
Wait for the process to finish. You should see a message that says "I: Building apk file..."
Check the folder where you placed the apktool.jar and roblox.apk files. You should see a new folder named "roblox" that contains the decompiled files of roblox APK file.
Congratulations! You have successfully decompiled roblox APK file with apktool. Now you can modify it as you wish. To recompile it into a new APK file, you need to follow these steps:
Make sure you have saved and closed all the files that you have modified in the "roblox" folder.
Open a command prompt window (cmd) and navigate to the folder where you placed the apktool.jar and roblox.apk files.
Type the following command and press enter:
java -jar apktool.jar b roblox
Wait for the process to finish. You should see a message that says "I: Copying unknown files/dir..."
Check the folder where you placed the apktool.jar and roblox.apk files. You should see a new file named "roblox/dist/roblox.apk" that is the recompiled version of roblox APK file.
Well done! You have successfully recompiled roblox APK file with apktool. Now you can sign and install it on your device. We will show you how to do that in the next section.
How to sign and install modified APK files
Before you can install your modified roblox APK file on your device, you need to sign it with a digital signature. This is a security measure that ensures that only authorized parties can modify and distribute APK files. If you try to install an unsigned APK file, you will get an error message that says "App not installed".
To sign your modified roblox APK file, you need to use another tool called apksigner. Apksigner is a tool for signing and verifying APK files. You can download apksigner from [here]. Extract the downloaded zip file and place the apksigner.jar file in the same folder where you placed the apktool.jar and roblox.apk files.
To use apksigner, you need to open a command prompt window (cmd) and navigate to the folder where you placed the apksigner.jar and roblox/dist/roblox.apk files. You can do this by typing "cd" followed by the folder path in the cmd window. For example:
cd C:\Users\YourName\Downloads\apktool
Once you are in the right folder, you can use the following command to sign your modified roblox APK file:
java -jar apksigner.jar sign --ks keystore.jks --out signed_roblox.apk roblox/dist/roblox.apk
This command will sign your modified roblox APK file with a keystore file named keystore.jks and output a new signed APK file named signed_roblox.apk. You can rename these files as you wish.
If you don't have a keystore file, you can create one by using this command:
keytool -genkey -v -keystore keystore.jks -alias alias_name -keyalg RSA -keysize 2048 -validity 10000
This command will create a new keystore file named keystore.jks with an alias name of your choice. You will be asked to enter some information and a password for your keystore file. Remember this password as you will need it later.
After signing your modified roblox APK file, you can install it on your device by using another tool called adb. Adb is a tool for communicating with Android devices. You can download adb from [here]. Extract the downloaded zip file and place the adb.exe file in the same folder where you placed the apksigner.jar and signed_roblox.apk files.
To use adb, you need to enable USB debugging on your device. This is a mode that allows your device to communicate with your computer via USB cable. To enable USB debugging, follow these steps:
Go to Settings > About phone > Tap on Build number seven times until you see a message that says "You are now a developer". Go back to Settings > Developer options > Enable USB debugging.
Connect your device to your computer via USB cable. You may need to allow USB debugging permission on your device.
After enabling USB debugging, you can install your modified roblox APK file on your device by using this command:
adb install signed_roblox.apk
This command will install your modified roblox APK file on your device. You should see a message that says "Success" if the installation is successful.
Congrats! You have successfully signed and installed your modified roblox APK file on your device. Now you can launch the roblox app and enjoy your modifications. But what kind of modifications can you do with apktool? Let's find out in the next section.
How to modify APK files with apktool
As we mentioned earlier, apktool allows you to decompile, modify, and recompile APK files with ease. You can use apktool to change various aspects of an app, such as its appearance, behavior, features, etc. In this section, we will show you some examples of common and advanced modifications that you can do with apktool on roblox APK file.
How to change roblox settings, graphics, sounds, etc. with apktool
One of the simplest modifications that you can do with apktool is to change the app's settings, graphics, sounds, etc. These are usually stored in the app's resources folder, which contains various files such as XML, PNG, MP3, etc. You can edit these files with any text or image editor of your choice.
For example, if you want to change the app's name from "roblox" to "myroblox", you can do this by editing the strings.xml file in the res/values folder. This file contains the text strings that are used in the app's interface. You can find the line that says:
roblox
And change it to:
myroblox
Similarly, if you want to change the app's icon from the default roblox logo to something else, you can do this by replacing the ic_launcher.png file in the res/mipmap folders with your own image file. Make sure that your image file has the same name and size as the original one.
Another example is changing the app's graphics settings, such as resolution, frame rate, quality, etc. These are usually stored in the game_settings.json file in the assets folder. This file contains the game's configuration parameters in JSON format. You can edit this file with any text editor of your choice.
For example, if you want to increase the resolution from 800x600 to 1280x720, you can do this by changing the line that says:
"resolution": [800, 600],
To:
"resolution": [1280, 720],
Similarly, if you want to increase the frame rate from 30 to 60, you can do this by changing the line that says:
"framerate": 30,
To:
"framerate": 60,
You can also change other graphics settings such as quality, anti-aliasing, shadows, etc. by editing the corresponding values in the game_settings.json file.
One more example is changing the app's sounds effects and music. These are usually stored in the sounds folder in the assets folder. This folder contains various audio files in MP3 or OGG format. You can replace these files with your own audio files or delete them if you don't want them.
For example, if you want to change the sound effect that plays when you jump from "jump.mp3" to "boing.mp3", you can do this by renaming or replacing the jump.mp3 file in the sounds folder with your own boing.mp3 file. Make sure that your audio file has the same name and format as the original one.
Similarly, if you want to change the background music that plays in the game from "music.mp3" to "rock.mp3", you can do this by renaming or replacing the music.mp3 file in the sounds folder with your own rock.mp3 file. Make sure that your audio file has the same name and format as the original one.
These are some of the common modifications that you can do with apktool on roblox APK file. You can experiment with different files and values to see what changes you can make. However, if you want to do more advanced modifications, such as adding custom scripts, models, assets, etc. to roblox, you need to use another tool called AssetStudio. We will show you how to do that in the next section.
How to add custom scripts, models, assets, etc. to roblox with apktool
Another type of modification that you can do with apktool is to add custom scripts, models, assets, etc. to roblox. These are usually stored in the content folder in the assets folder. This folder contains various subfolders that contain the game's scripts, models, assets, etc. You can add your own files or replace the existing ones with your own files.
However, to do this, you need to use another tool called AssetStudio. AssetStudio is a tool for extracting and importing assets from Unity games. Roblox is a game that uses the Unity engine, so you can use AssetStudio to manipulate its assets. You can download AssetStudio from [here]. Extract the downloaded zip file and place the AssetStudio.exe file in a folder of your choice.
To use AssetStudio, you need to open it and load the roblox APK file. To do this, follow these steps:
Launch the AssetStudio.exe file and click on File > Load Folder.
Navigate to the folder where you placed the roblox APK file and select it.
Wait for AssetStudio to load the roblox APK file. You should see a list of assets on the left panel and a preview of the selected asset on the right panel.
Once you have loaded the roblox APK file with AssetStudio, you can extract or import assets from it. To extract an asset, follow these steps:
Select the asset that you want to extract from the left panel.
Click on Export > Export selected assets.
Choose a folder where you want to save the extracted asset and click OK.
To import an asset, follow these steps:
Select the asset that you want to replace from the left panel.
Click on Import > Import selected assets.
Choose a file that you want to import as the new asset and click OK.
These are some of the basic operations that you can do with AssetStudio on roblox APK file. You can use AssetStudio to add custom scripts, models, assets, etc. to roblox by importing your own files or replacing the existing ones with your own files.
For example, if you want to add a custom script that gives you unlimited money in roblox, you can do this by importing a Lua script file that contains the code for this feature. You can find such scripts online or create your own. You need to import this script file as a TextAsset in AssetStudio and replace an existing script file in roblox with it.
Similarly, if you want to add a custom model that changes your character's appearance in roblox, you can do this by importing a FBX or OBJ file that contains the model for this feature. You can find such models online or create your own. You need to import this model file as a Mesh in AssetStudio and replace an existing model file in roblox with it.
You can also add custom assets such as textures, sounds, animations, etc. to roblox by importing them as Texture2D, AudioClip, AnimationClip, etc. in AssetStudio and replacing the existing ones with them.
These are some of the advanced modifications that you can do with apktool and AssetStudio on roblox APK file. You can experiment with different files and values to see what changes you can make. However, you should be careful and aware of the risks and limitations of using apktool and AssetStudio with roblox. We will discuss them in the next section.
