1. To ensure that the phone has sufficient power.
2. Back up personal data in your phone (contacts, text messages, applications, etc.).
3. Download the firmware package.
Step 1. first copy the firmware package to the root directory of the mobile phone memory card, and press the power key for a long time to shut down. After confirming that the phone is turned off, press and hold the power button and the volume button at the same time, and after about ten seconds, a yellow text on the black background will appear on the screen, indicating that the phone has entered Recovery mode. Use the volume up and down buttons to move the cursor to the "manually select installation package" location and click the power button to confirm. Next, use the volume up and down buttons to select the firmware package, and click the power button to confirm.
Step 2. Then there are no complex operation steps, users just need to wait for the brush machine to complete by itself. During the brushing project, the phone always keeps the screen lit, and in addition to the constantly scrolling yellow text, there is a blue progress bar displayed at the bottom of the green robot. Finally, the word "installation is complete" will be displayed at the bottom of the screen. At this point, OPPO Finder brushing is over. Choose to restart the system immediately according to the prompt. The rebooted phone is already the latest system.
Each upgrade changes big or small, but the interface still retains the original style of OPPO Finder. In addition, users can select about the phone in the settings options, and you can check the version number of the current system in the "version number", so you can determine whether it is the latest system or not. OPPO Finder manual flashing is not complicated. In addition to the official firmware, this method can also be used for third-party firmware packages in some forums.
