If you’ve forgotten your password, pattern, or PIN on your OPPO A3x 4G, don’t worry—you can still regain access to your device with a hard reset. A hard reset, also known as a factory reset, will erase all data on the phone and restore it to its original factory settings. This is the most effective method for bypassing a locked screen and resolving persistent software issues.
In this comprehensive guide, we’ll walk you through the step-by-step process to hard reset your OPPO A3x 4G using the hardware buttons. We’ll also cover what to do before performing a reset, what to expect afterward, and how to protect your data going forward.

Why You Might Need a Hard Reset
There are several scenarios where a hard reset is the best solution:
- You’ve forgotten your screen lock password, PIN, or pattern.
- The phone is stuck in a boot loop or frozen screen.
- You want to erase all data before selling or giving away the phone.
- Software glitches or malware have affected the system performance.
A hard reset will remove all apps, data, contacts, and settings. It’s essentially a “clean slate” for your device.
Important Pre-Reset Warnings
Before you begin, please be aware of the following:
- All data will be erased – This includes photos, apps, contacts, messages, and accounts. If possible, back up important data beforehand.
- Google Account verification – After the reset, you may need to log in with the Google account previously synced to the device. This is part of Google’s Factory Reset Protection (FRP).
- Ensure your battery is at least 50% charged to prevent shutdown during the reset process.

5. Confirm the Reset

What to Expect After the Reset
Once your OPPO A3x 4G has rebooted, you’ll need to:
- Go through the initial setup process.
- Connect to Wi-Fi.
- Enter the previously used Google account credentials (due to FRP).
- Set a new PIN, pattern, or password.
- Reinstall apps and restore your data if you backed it up previously.
Tips to Avoid Getting Locked Out Again
To prevent future lockouts or data loss, consider the following:
1. Use Smart Lock
Enable Smart Lock to keep your device unlocked in trusted locations or when it detects a trusted device nearby.
2. Set Up a Recovery Email
Ensure your Google account has a backup email or phone number to aid in password recovery.
3. Regular Backups
Use Google Drive or OPPO’s cloud services to regularly back up your contacts, messages, photos, and app data.
4. Write Down Your Password
If you’re prone to forgetting passwords, store them in a secure place or use a trusted password manager app.
Alternative: Factory Reset from Settings (If Unlocked)
If you still have access to your phone and simply want to reset it:
- Go to Settings.
- Tap on Additional Settings.
- Select Backup & Reset.
- Tap on Erase All Data (Factory Reset).
- Confirm by entering your password, then tap Erase Data.
This method is easier and safer if your device is functioning normally.
Troubleshooting Common Issues
Recovery Mode Not Working?
- Make sure you’re pressing Volume Down + Power at the same time.
- If nothing happens, try Volume Up + Power instead.
- Hold the buttons for at least 10 seconds before releasing.
Forgot Google Account After Reset?
