There are various reasons you may want to apply a hard reset to the Oppo A55s. Some of the most common reasons include installing custom firmware, wanting to wipe the data before handing the smartphone to someone else, and troubleshooting software issues.

Formatting the Oppo A55s smartphone is handy for many things. If you are hard resetting to solve software issues, you should check for software updates from the Settings app, which will update the firmware. Once you are off the old firmware build, you should notice the bugs are gone. If software problems persist, you should send it to Oppo for a service.

This tutorial demonstrates how to hard reset the Oppo A55s 5G A102OP smartphone.

How to Hard Reset Oppo A55s 5G A102OP

You can hard reset the Oppo A55s 5G A102OP smartphone from the Settings app and Recovery Mode. We recommend performing the hard reset from the Settings app unless you are installing custom firmware. If you are installing a custom ROM you may find it easier to hard reset/format data from Recovery Mode. So here is how to hard reset via the Settings app first:

1. With the Oppo A55s 5G turned on, tap Settings > Additional settings.

2. Tap Backup & Reset > Erase all data (factory reset).

3. Tap Erase all data > Erase data.

The Android operating system will eventually restart once the hard reset is applied and you need to set up the smartphone again. You also need to sign in to your Google account. You can visit Google.com on any computer to reset your password if you need.

If you are installing custom firmware, you can hard reset via Recovery Mode instead. Here is how:

1. With the Oppo A55s 5G turned off, press and hold the Power + Volume Down buttons simultaneously until ColorOS Recovery is on the screen.

2. Select your language.

3. Tap Wipe data > Format data > Format.

4. Tap Reboot.

The Oppo A55s 5G smartphone will reboot out of ColorOS Recovery and the Android operating system will boot up. You need to set up your Android smartphone again which includes signing in to your Google account. This Google account is the same one you already have, so enter your existing email and password. You can reset the Google account password from any computer by visiting the sign-in page on Google.com.

In conclusion, that is how to hard reset the Oppo A55s 5G A102OP smartphone.
