Oppo Find X9: How to Fix 'PIN Not Accepted' Error

Understanding the 'PIN Not Accepted' Issue

• 💡 The "PIN not accepted" error on an OPPO Find X9 can occur if you've forgotten your PIN or if it's simply not being recognized.
• ⚠️ The primary methods to resolve this issue involve either visiting an authorized service center or performing a factory reset.

Data Retention Options

• 🤝 If you wish to retain your data, the recommended approach is to visit a certified or authorized OPPO service center with proof of purchase.
• 👆 If you had previously registered your fingerprint unlock, you can use it to access your phone and potentially change the PIN or reset settings via the device unlock or backup and reset menus.

Factory Reset Procedure (Data Loss)

• 🔌 To perform a reset when the PIN is not accepted and fingerprint is unavailable, the phone must be completely powered off.
• ⚠️ Warning: This method will result in data loss.
• 🚀 To enter recovery mode, hold the Volume Down and Power buttons simultaneously until the OPPO logo appears, then continue holding Volume Down until a foreign language menu displays.
• ⚙️ Navigate using Volume Down to select "Format data" and confirm the action by pressing the Power button.
• 🔢 You will be prompted to enter a verification code (e.g., 2917) to proceed with the format.

Post-Reset Considerations: Google FRP

• 🔒 After a factory reset, be aware of Google Factory Reset Protection (FRP).
• 🔑 You will need to log in with the Google account credentials that were previously associated with the phone to regain full access.
