Got it
You’re on Android 5.1.1 (Lollipop) and when trying to log into WhatsApp you see the error:
This usually happens because:
Here’s how to fix it:

“You need official WhatsApp to login”
This usually happens because:
- The version of WhatsApp you installed is outdated or not supported.
- You downloaded WhatsApp from a non-official source (like a modded APK: GBWhatsApp, FMWhatsApp, etc.), which WhatsApp now blocks.
- Play Store doesn’t give you the latest version because Android 5.1.1 is too old.
Here’s how to fix it:
Fix Steps
- Uninstall any unofficial/modded WhatsApp
- Go to Settings → Apps → WhatsApp → Uninstall.
- Remove GBWhatsApp, FMWhatsApp, YoWhatsApp, etc. if installed.
- Download the official WhatsApp
Since Google Play may not give updates for Android 5.1.1, you need the last version supported.
- Open WhatsApp official download page.
- Or use a safe APK source like APKMirror and download:
WhatsApp Messenger (v2.23.xx or latest that supports Android 5.0+)
- Install the APK
- Enable Unknown Sources:
Settings → Security → Unknown sources → Allow. - Open the downloaded APK and install.
- Enable Unknown Sources:
- Verify your number
- Open WhatsApp, enter your phone number, and complete SMS/Call verification.
- Restore chats (optional)
- If you had backups in Google Drive, you can restore them.
- On Android 5.1.1, some newer backup features may not work — you might only restore local backups from /WhatsApp/Databases/.
Important Notes
- WhatsApp dropped support for Android 4.4 and below, but Android 5.1.1 is still supported (as of 2025).
- If you’re using a custom ROM or very old device, Play Services might also need updating. Get the latest Google Play Services APK for Android 5.
- If you’re on a modded WhatsApp, you must switch to the official app — otherwise you’ll keep getting blocked.
