With USB Debugging active, connect the OPPO A5 2020 to a computer (Windows or Linux) via a USB cable. On the computer, you need the ADB and Fastboot platform tools installed. Open a command prompt or terminal window in the folder containing these tools and type the command:

First and foremost, it is crucial to acknowledge the primary obstacle: OPPO deliberately disables traditional Fastboot access on most of its devices running ColorOS 6 and later, including the OPPO A5 2020. Pressing common combinations like Volume Down + Power or Volume Up + Power during startup will only lead to the device’s standard Recovery Mode or a simple reboot. Therefore, the conventional "hold buttons while turning on" method is ineffective. Accepting this reality is the first step; attempting fruitless button presses will only lead to frustration.

In the realm of Android troubleshooting and customization, few tools are as powerful yet as elusive as Fastboot Mode. Often referred to as the "bootloader," this low-level interface allows users to flash custom recoveries, unlock the bootloader, or restore critical system partitions. For owners of the OPPO A5 2020, a reliable mid-range device, accessing Fastboot is not as straightforward as it is on a Google Pixel or a OnePlus phone. OPPO’s proprietary ColorOS imposes a unique layer of security that often blocks traditional key combinations. Consequently, opening Fastboot on this device requires a specific understanding of its software limitations and a deliberate, technical approach.

adb reboot bootloader At this moment, the phone’s screen will go black and then… typically stay black. This is the most confusing part of the process. On the OPPO A5 2020, Fastboot Mode does display a visible menu or text on the screen. The screen remains off, but the device is actually in a functional, albeit headless, Fastboot mode. You can verify this by typing the command fastboot devices on your PC. If the computer returns a serial number, the phone is successfully in Fastboot, despite the blank display. To exit this blank state, you must hold the power button for 10–15 seconds to force a normal reboot.

Given the complexity and the "blank screen" behavior, many advanced users prefer an alternative route: or using OPPO’s official flashing tool (like MSM Download Tool) for deep-level repairs. However, for the specific purpose of opening Fastboot, the ADB method remains the only viable path.
