Before you start
- Make sure the firmware matches the exact model (CPH1911). Flashing the wrong firmware can brick the device.
- Backup any important data if the device is still accessible. Flashing will erase user data.
- Use a reliable USB cable and a stable power source. Prefer a fully charged battery or keep the phone connected to power while flashing.
- Install required USB drivers for OPPO/MediaTek on your PC before connecting the device.
Tools you may need
Common tools for flashing this type of firmware include SP Flash Tool and other vendor-specific flash tools. Use the tool that matches the firmware format inside the package.
Flashing instructions (general guide)
- Extract the downloaded firmware package to a folder on your PC.
- Install the proper USB drivers for your phone on the PC.
- Open the flashing tool that matches the firmware format (for example, SP Flash Tool for MediaTek scatter files).
- Load the firmware files into the flashing tool according to the tool instructions.
- Power off the phone. If the phone is dead, follow the tool-specific method to enter download mode (often: connect while pressing volume keys).
- Connect the phone to the PC using a good USB cable. The tool should detect the device.
- Start the flashing process and wait until it completes. Do not disconnect the phone during flashing.
- When flashing finishes, disconnect and try to power on the phone. Allow the first boot several minutes to complete system setup.
Troubleshooting tips
- If the tool does not detect the phone, confirm drivers are installed and try different USB ports or a different cable.
- If the phone still fails to boot after flashing, try a factory reset from Recovery mode.
- For charging errors, try replacing the charging port or the cable if software fixes do not work.
