If your Oppo Reno 12 has become sluggish, keeps freezing, is stuck on the boot logo, or you are about to sell or trade it in, an Oppo Reno 12 hard reset wipes the device back to its factory state. The Reno 12 runs ColorOS 15 (upgradable from the ColorOS 14 it may have shipped with), so the menus below follow Oppo’s own software layout. Read the warning about Google’s FRP lock before you wipe anything, because resetting the wrong way can lock you out of your own phone.
When you need a hard reset
A hard reset (also called a factory reset) is the right move when softer fixes have failed. Consider it if:
- The phone is frozen, crashing, or constantly restarting and a normal reboot does not help.
- Apps misbehave system-wide after an update and clearing individual app caches changes nothing.
- You forgot your lock screen PIN or pattern and need to start over.
- You are selling, gifting, or returning the device and want your data gone.
- Performance has degraded over months of use and you want a clean slate.
If you only suspect one bad app or setting, try that fix first. The steps here apply to most Android phones too, so our general guide on how to hard reset any Android mobile is worth a look if you own several devices.
Before you start
A factory reset is permanent. Once it runs, photos, messages, downloaded files, accounts, and app data are erased and cannot be recovered from the phone itself. Take two precautions:
- Charge the battery to at least 50%. A reset that loses power partway through can leave the phone in a broken state.
- Back everything up. Sync your photos to Google Photos, contacts to your Google account, and use Oppo’s built-in cloud or local backup. Our walkthrough on how to back up and restore Android devices covers both Google and manufacturer tools so nothing important is lost.
Critically, know your Google account email and password. After a reset, the Reno 12 will ask for the Google account that was previously signed in. This is the FRP (Factory Reset Protection) check, explained near the end of this article.
Method 1 – factory reset from Settings (recommended)
If the phone still boots and you can unlock it, do the reset from inside the system. This is the cleanest way to perform an Oppo Reno 12 hard reset because it signs you out of your accounts properly first.
- Open Settings.
- Scroll down and tap About device (on some builds, look under Additional settings).
- Tap the button for Reset phone (sometimes shown as Back up and reset or Reset options).
- Choose Erase all data (factory reset). Avoid the lighter “reset system settings” option if your goal is a full wipe.
- Confirm, enter your lock screen password if prompted, and let the phone reboot and erase itself.
To remove the FRP lock cleanly, you can also go to Settings > Accounts and remove your Google account manually before resetting. This avoids the post-reset account prompt entirely.
Method 2 – hard reset from Recovery mode
Use this method when the phone will not boot, is stuck on the Oppo logo, or you cannot get past the lock screen. It uses the hardware buttons and the recovery menu, so no working system is needed.
- Power the phone off completely. Hold the Power button and choose Power off, or hold Power for around 10 seconds to force it off.
- Enter recovery: press and hold the Power button + Volume Down button together until the screen lights up, then release. The Reno 12 boots into the recovery screen.
- Recovery is usually touch-enabled on ColorOS. Select your language if asked.
- Tap or navigate to Wipe data (Wipe data and cache).
- Choose Format data or Wipe data and confirm. You may need to enter a verification code shown on screen.
- When the wipe finishes, select Reboot to restart the phone.
If the button combo does not land you in recovery, power the phone fully off and try again, holding both buttons firmly. For a deeper explanation of every option in this menu, see our guide on how to use Recovery mode to fix your Android phone.
A note on the Google FRP lock
Factory Reset Protection is an anti-theft feature built into Android. After any hard reset, the Reno 12 demands the Google account and password that were last signed in on the device. If you do not have those credentials, the phone stays locked at setup even though it is wiped, which is exactly what stops thieves from reusing a stolen handset.
Always remove your Google account from Settings > Accounts before resetting, especially before selling. If you are locked out of a phone you legitimately own, you can sometimes erase and reset it remotely through Google’s tool, explained in our guide to reset with Find My Device. If you ever need to connect the phone to a computer for flashing or driver work, our page on how to download Android USB drivers will help.
Frequently asked questions
Will a hard reset remove the Google FRP lock on my Oppo Reno 12?
No. A reset wipes your data but the phone will still ask for the last Google account that was signed in. Remove your Google account in Settings before resetting, and keep your account email and password handy so you can sign back in afterward.
What buttons put the Oppo Reno 12 into recovery mode?
Turn the phone off completely, then press and hold the Power button and Volume Down button at the same time until the recovery screen appears. From there choose Wipe data to perform the hard reset.
Can I recover my files after factory resetting the phone?
Not from the phone itself, because the data is erased. The only way to get your files back is from a backup made beforehand, such as Google Photos, your Google account sync, or an Oppo cloud or local backup. Always back up before you reset.
