  1. Enable Developer Options:
    • Go to Settings > About Phone > Tap Version > Tap Build Number 7 times until you see "You are now in Developer Mode".
  2. Enable OEM Unlocking:
    • Go to Settings > Additional Settings > Developer Options.
    • Turn on OEM Unlocking.
  3. Apply for Unlocking (In-App Method):
    • On ColorOS, there is usually an "Oppo Unlock Tool" or you must find the "Unlock Bootloader" setting inside Developer Options.
    • Tap "Test connection" and then "Apply for unlocking".
    • You will be prompted to log in with an Oppo account.
    • The Waiting Game: Oppo typically enforces a waiting period (often 7 days or up to a month). You must wait for this timer to count down within the app. Do not skip this, or the unlock will fail.
  4. Deep Testing Mode:
    • Once the timer is up, go back to the Developer Options > Unlock Bootloader menu.
    • Tap "Start the deep test". The phone will reboot into a "Fastboot Test" mode.
  5. Connect to PC:
    • Connect the phone to your PC via USB.
    • Open a Command Prompt/PowerShell window in your ADB folder.
    • Type fastboot devices to ensure it is detected.
    • Type fastboot flashing unlock.
    • On the phone screen, use the volume keys to select Unlock and press the Power button to confirm.
    • The device will wipe data and reboot.
