Since the phone has UFS memory, please go to "Fire Configuration" in the "Configuration" tab of "QFIL" and change the device type to UFS. Step 2: Connect the mobile phone to the computer through usb, and hold down the three buttons at the same time. After the phone is turned off (when the computer gives a disconnect prompt), press the volume up continuously, while the volume is down, and the power button should not be released.
