3. What If `adb reboot bootloader` Just Reboots Normally?

If your phone simply restarts normally instead of going into Fastboot:

Your USB drivers are incorrectly installed. Reinstall Oppo drivers.
Your phone’s bootloader does not support standard Fastboot. Some Oppo A37 variants (carrier-locked) have the Fastboot interface removed. In this case, you cannot open Fastboot at all via software.

Problem: `adb reboot bootloader` reboots into a black screen and then turns off

Connect to PC: Plug your USB cable into your computer (not a wall charger).
Power Off: Turn off the OPPO A37 completely.
The Sequence: Press and hold the Volume Down button.
Insert Cable: While keeping the Volume Down button held down, plug the USB cable into the phone.

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

Method 1: Hardware Key Combination (Most Reliable)

Power off the device completely.
- Wait for vibration to confirm shutdown.
Press and hold Volume Up button.
While holding Volume Up, press and hold Power button.
Keep both buttons pressed until the screen turns on.
When you see the Oppo logo, release the Power button but keep holding Volume Up.
After 2–3 seconds, you should see "Fastboot" in small text at the top left or center of the screen.

If this does not work, try Volume Down + Power instead (some A37 variants use this).
