Locate TP_KCOL0 and TP_KROW0 near the MT6765 chip. Short them with tweezers.
Use tools like MTK Client (open-source) that exploit known bypasses, or UnlockTool with paid credits.

(short for BootROM Mode ) is a low-level, pre-boot state built into MediaTek processors—which power many OPPO models, including the A-series, F-series, and some Reno devices.
Despite the method, you might find on your device. Here’s why: oppo brom mode work
When software-based commands cannot break through the Preloader port block, technicians use a physical connection to force a hardware-level BROM execution:
Removing the "Google Account Verification" lock after a hard reset.
If successful, the progress bar will move to 100%, and your OPPO phone will reboot with a clean system.
If your computer refuses to interact with your OPPO device in BROM mode, verify these configuration points: Locate TP_KCOL0 and TP_KROW0 near the MT6765 chip
: On some firmware versions, the phone might jump straight to charging or "Preloader" mode instead of staying in BROM.
This article explores what OPPO BROM mode is, how it works, why it is critical for unbricking and bypassing security, and how to access it on your device. What is OPPO BROM Mode?
If the BROM finds everything intact, it hands control over to the Preloader, which is stored in the device's eMMC or UFS flash storage. The Preloader initializes volatile memory (RAM) and prepares basic hardware components.
It allows flashing tools (like SP Flash Tool or MTKClient) to read/write flash memory, bypassing bootloader locks and FRP (Factory Reset Protection). When to Use BROM Mode on Oppo | Condition | Requirement | |-----------|-------------| | |
→ Reconnect battery → Power on.
The kernel boots up, loading the user interface and security protocols.
Keep holding for about 3–5 seconds. The screen should stay black. Open "Device Manager" on your PC to confirm it appears under Ports as "MediaTek USB Port." Method 2: The Test Point Method (For Hard-Bricked Devices)
