Oppo Hard Reset Not Working

Is your Oppo phone behaving obnoxiously? Do you want to hard reset it? Oh! But Oppo hard reset is not working? No worries. In the following sections, you will learn three easy ways to fix the issue.

Hard resetting your Oppo phone, or any other smartphone for that matter, allows you to use it as a new device where you first need to set it up from scratch, and then customize it according to your preferences. However, if you are unable to hard reset your smart device, this could be due to some security barriers that you must pass before the phone permits you to do that.

How to Fix “Oppo Hard Reset Not Working”

If you tried to fix the errors with your Oppo phone but the hard reset is not working, the following solutions may help you eliminate the error, including the one related to hard reset so that you can use your device normally.

Solution 1: Hard Reset Oppo Phone from the Settings App

The simplest way to hard reset an Oppo phone is from the ‘Settings’ app. However, for this method to work, you must have access to your smartphone. If the device is protected with the lock screen password and you forgot it, you must first reset it, and then proceed towards hard resetting.

To reset the lock screen password, you must ensure that your Oppo phone is more than 25% charged. Once this is done, you can do the following:

  • On the lock screen, tap the Emergency call option from the bottom-left.
  • On the Emergency calls only screen, dial *#08564789#. Note: This code may change when the company releases new security patches or version updates.
  • Tap the Call button.
  • Tap OK on the Call failed box.
  • Call the same number and hit OK at least four more times. (At least five calls in total. You can even do this six to seven times, but it should not be less than five times.)
  • Once done, delete the number and dial *#899# instead.
  • On the EngineerMode screen, tap manual test.
  • When the next window appears, swipe the screen to the left to get to the Others page.
  • Check and confirm that the Main Board version is at least V1.1. Note: This method may not work if the Main Board version is lower than V1.1.
  • While still on the Others page, tap Reading reset complete indicator.
  • Ensure that PASS appears on the top of the next screen.
  • Swipe the screen to the left again.
  • Back on the Others page, tap Key Status.
  • On the Key Status window, note and confirm that the statuses of all the security measures are set to PASS.
  • Next, swipe your screen up to access your Oppo phone’s home screen.

Additional Tip

If you didn’t set a lock screen password but the phone still prompts you for it, try entering 0000 or 000000 and see if it works.

Once the smartphone is unlocked, you can follow the instructions given below to hard reset it:

  • Tap Settings.
  • Tap Additional settings.
  • Tap Back up and reset.
