Quick Summary (Start Here):
*#813# code likely still works.If you are holding a locked OPPO phone, you might be confused by the conflicting advice online. One video tells you to dial a secret code, another tells you to draw an “L” on the screen, and a third tells you to take the phone apart.
Why is it so messy? Because OPPO changes its security architecture with every major ColorOS update. A method that works on an OPPO A15 will fail instantly on a Reno 10.
This Page is your roadmap. We have organized every working bypass method by Android version and chipset. Instead of guessing, use the diagnostic trick below to find your exact Android version, then click the guide that matches your device.
Before you start trying random methods, let’s find out exactly what is running on your phone.
*#899# or *#800#.Target Devices: Older models like OPPO A5s, A12, F9, Reno 2.
If you have an older device that hasn’t been updated since 2021, you are in luck. This is the “Golden Era” of FRP bypassing. You do not need Wi-Fi, a PC, or any apps.
The Magic Code:
*#813# or *#812#.Detailed Guide:
Is the code not working, or do you need to downgrade your firmware to make it work?

Target Devices: OPPO A54, A74, Reno 5/6 running ColorOS 12/13.
When ColorOS 12 arrived, OPPO patched the engineer codes. The community shifted to using “Accessibility Shortcuts” to trick the Google Assistant into opening a browser.
The Strategy:

This method requires precise timing with gestures. If you are stuck on Android 12 or 13:

Alternatively, check our general Android 13 FRP Bypass guide.
Target Devices: OPPO A78 5G, A58, Reno 8/10/11 running ColorOS 14.
This is where most users get stuck in 2026. On these versions, the “Reset Phone” button inside Settings is grayed out, and TalkBack is often blocked.
The Fix: Clone Phone Injection
You cannot reset the phone directly. Instead, you must use OPPO’s official “Clone Phone” app to transfer a specific launcher app from a second phone.

This is the most complex method but the only one working for new devices.

Sometimes, checking your Android version is impossible because the phone is locked. In these cases, it is smarter to choose a method based on your phone’s hardware (Chipset).
Some older budget phones have specific vulnerabilities that make them very easy to unlock using a PC, avoiding all the manual work.
Specific Guide:
If you own an OPPO A15 or similar MediaTek device, don’t waste time with Clone Phone.

If you are a technician or have a PC handy, using a professional tool is often faster than tapping on screens for 20 minutes.
A: It depends entirely on your software version. If your OPPO is running Android 11 or older (ColorOS 11), yes, it works instantly. However, on Android 12, 13, and 14, this vulnerability has been patched by OPPO. Dialing it will do nothing. For newer phones, you must use the [Clone Phone Method].
A: This is a security feature introduced in late 2024 security patches (Android 14/15). OPPO now prevents users from resetting the phone while in the “temporary” setup state.
A: We strongly advise against it. When using the “Clone Phone” method, transferring the Activity Launcher app from a non-OPPO phone (like Samsung) often causes the app to crash immediately upon opening. For a smooth unlock, use another device from the BBK family (OPPO, Realme, or OnePlus).
A: For 90% of cases (Android 12-15), No. You can do it entirely on the phone using TalkBack or Clone Phone. However, for certain older MediaTek models (like the OPPO A15) or if you are stuck in a boot loop, using a PC FRP Tool like UnlockTool or DroidKit is often faster and cleaner.
A: Yes. The FRP bypass process usually concludes with a full factory reset to permanently remove the previous Google account association. All photos, contacts, and messages on the device will be wiped.
