Android Package Fix

Errors​

  • 1: "App not installed as package appears to be invalid"
  • 2: "App not installed as package conflicts with an existing package"
  • 3: "App not installed as app is not compatible with your phone"
  • 4: "There was a problem parsing the package"
  • 5: "App not installed"

Before you continue...​

  • 1/2/5: Do you already have Roblox or Delta installed? Try deleting them first, then reinstall.
  • 1/2/4/5: Are you using the latest version of Android? If not, update it and then reinstall. You should have Android 11 or higher at a minimum.
  • 1/2/4/5: Are you downloading it from https://deltaexploits.gg? If not, download and install it from there.
  • 1/4/5: Did the APK download fully/correctly? Try downloading it using another browser or a VPN.
  • 1/2/5: Have you enabled “Allow from unknown sources” for your browser? If not, enable it and try reinstalling.

Settings > Apps > Special App Access > Install Unknown Apps, select your browser (e.g., Chrome), and toggle Allow from this source.

  • 1/2/5: Is Play Protect enabled in the Play Store? Try disabling it, then reinstall.

Open the Google Play Store app, tap your profile icon, select Play Protect, then Settings (gear icon), and toggle off Scan apps with Play Protect.

  • 1/2/5: Do you have multiple profiles or a Secure Folder on your device? Check if Roblox or Delta was installed there.
  • 1/4/5: Have you tried to restart your device? Do so, then try to re-install.
  • 1/3/4/5: What is your phone’s CPU architecture? (You can use CPU-Z to find out.) If it is ARM32, that might be the issue, since Delta sometimes doesn’t support ARM32.

As of now, Delta only supports "arm64-v8a" and "armeabi-v7a".

  • 1/2/4/5: Have you checked if the Roblox folder exists? If not, delete it.

Install ZArchiver, go to 0/storage/emulated/Android/data then delete the com.roblox.client folder (if it is there).

  • 5: Do you have enough storage? Delete some files you do not need, then try to re-install.
  • 1/4/5: Have you tried clearing the cache/data for your package installer?
  • 1/4/5: Have you tried using a different package installer (perhaps a file manager instead of a browser)?

If none of the solutions worked, you may still have Roblox installed, even if it seems uninstalled. Here is the solution:

Instructions (NO PC)​

  1. Enable Developer Mode

    • Settings → About Phone → tap Build Number 7 times

  2. Enable USB Debugging

    • Developer Options → USB Debugging → ON

  3. Install Termux

    • Go to F-Droid and click Download F-Droid. Install the APK.
    • Go back to F-Droid and scroll down to Find Apps.
    • Search for Termux, scroll down until you see that exact result, and install it.

  4. Prepare Termux

    • Open Termux

    • Update packages:

      pkg upgrade

    • Install ADB tools:

      pkg install android-tools

  5. Enable Wireless Debugging

    • Developer Options → Wireless Debugging → ON + Allow the connection
    • Tap Pair device with pairing code
    • You need to make sure Termux or Settings is in split view or in a floating window for the next step.

  6. Pair Termux/ADB with Your Device

    • In Termux, run:

      adb pair IP:PAIRING_PORT
      • Enter the pairing code shown on the phone

    • Connect to the main port:

      adb connect IP:MAIN_PORT

  7. Uninstall the Conflicting App

    adb uninstall com.roblox.client

Try running adb shell pm uninstall --user 0 com.roblox.client instead if the error still appears.

Run adb shell pm list users to see all the profiles on your phone, in case you have others you do not know about. Change 0 to the profile number, and the command for each profile.

Other commands:
adb shell cmd package uninstall --user 0 com.roblox.client AND adb shell cmd package clear com.roblox.client
adb shell pm install-existing com.roblox.client AND adb uninstall com.roblox.client

Instructions (With PC)​

If you do not want to use Termux, you can run the adb commands on a computer instead.

  1. Download ADB (Platform Tools)

  2. Enable Developer Mode

    • Settings → About Phone → tap Build Number 7 times

  3. Enable USB Debugging

    • Developer Options → USB Debugging → ON

  4. Connect Your Phone

    • Plug your phone into your computer using a USB cable
    • Allow the USB debugging prompt

  5. Open a Terminal in Platform Tools

    • Open Command Prompt / PowerShell / Terminal inside the extracted folder

For the following commands on MacOS/Linux, you will need to add ./ before adb.

  1. Check Connection

    adb devices
    • Accept the prompt on your phone if it appears

  2. Uninstall the Conflicting App

    adb uninstall com.roblox.client

    If that does not work:

    adb shell pm uninstall --user 0 com.roblox.client

  3. (Optional) Check Other Users

    adb shell pm list users
    • Replace 0 with the correct user ID if needed

Other commands:
adb shell cmd package uninstall --user 0 com.roblox.client AND adb shell cmd package clear com.roblox.client
adb shell pm install-existing com.roblox.client AND adb uninstall com.roblox.client
