Here’s a clear, step-by-step content draft on how to open Fastboot Mode on an Oppo A37.

Method 2: ADB Command (Requires USB Debugging)

Prerequisites:

  • USB Debugging enabled in Developer Options.
  • ADB installed on your PC.
  • Oppo USB drivers installed.

Steps:

  1. Connect phone to PC via USB.
  2. Open Command Prompt / Terminal in the ADB folder.
  3. Type: 
    adb devices
    (Verify your device is listed – authorization required on phone)
  4. Then type: 
    adb reboot bootloader
  5. The phone will reboot into Fastboot mode.

Exiting Fastboot mode

  • Use the phone’s Power button to restart: press & hold Power until it reboots.
  • Or from a connected PC run:
fastboot reboot

What You'll Need:

  • A PC with USB drivers installed (Oppo USB Drivers recommended)
  • The original or a high-quality USB cable
  • Oppo A37 fully charged or at least 50% battery

Step 1: Enable Developer Options and USB Debugging on Oppo A37

  1. On your Oppo A37, go to Settings → About Phone.
  2. Scroll down to Version (or “Build Number”). Tap it 7 times continuously. You will see a toast message: “You are now a developer.”
  3. Go back to Settings → Developer Options (usually under “Additional Settings” or near the bottom).
  4. Turn on Developer Options (toggle at the top).
  5. Scroll down and enable USB Debugging. Confirm any warning prompt.

How to Confirm You Are in Fastboot Mode

If successful, you will see a screen that looks distinct from your normal operating system. It usually displays:

  • A large Bunny logo (in older Android versions) or the word "Fastboot" in large text.
  • Text at the bottom usually reading: "Fastboot Mode..." or "Press Power key to reboot."

Step 3: Connect Your Phone and Test ADB

  1. Open a command prompt in your ADB folder. (Navigate to C:\adb, then hold Shift + right-click and select “Open PowerShell window here” or “Command Prompt”).
  2. Connect your Oppo A37 to the PC via USB.
  3. On your phone, a popup will ask “Allow USB debugging?” – Check “Always allow from this computer” and tap OK.
  4. In the command window, type: 
    adb devices
    You should see your device listed as device (not unauthorized). If you see unauthorized, check the popup on your phone.

4. Hardware Key Combination for Recovery (Not Fastboot)

For reference, if you need Recovery Mode (not Fastboot), the Oppo A37 uses:

  • Power off the phone.
  • Press and hold Volume Down + Power together.
  • Release when the Oppo logo appears, then quickly press Volume Up once. This enters ColorOS Recovery.

Do not confuse Recovery Mode with Fastboot Mode—they serve different purposes.
