You should always clean flash new custom firmware on a smartphone which means if you plan on installing custom firmware on the Oppo Reno 5 smartphone, you should hard reset/factory reset it first.

You may also want to hard reset the Oppo Reno 5 to wipe all its data at once and reset the factory settings. Wiping the data from the Settings app or stock recovery environment is common before selling a smartphone. And restoring the factory settings is common among those looking to troubleshoot software-related problems. If you are troubleshooting and still have problems, you should check for software updates after setting up Android again. A new software update will update the firmware and remove bugs. If that does not work, you should send it to Oppo for a service.

This tutorial demonstrates how to hard reset the Oppo Reno 5 4G CPH2159 smartphone and reset it to its factory settings.
