How to Flash Huawei P20 Pro with Flash Tool, Firmware or Stock ROM

Huawei P20 Pro Firmware

Precautions



  • When mapping is done, a port can be used directly and does not need to be mapped again.
  • The path of the software to be loaded cannot be too deep. Otherwise, the software cannot be properly loaded.
  • Avoid touching the USB cable during the loading process.
  • Loading will erase the radio frequency (RF) NV information from a phone. Use with caution. When the loading is done, RF calibration and comprehensive tests need to be performed on the Huawei P20 Pro.
  • In some PCs running Windows 7, the software loading may fail at 40% of the progress because the ADB port is occupied. If this is the case, then, use the appended tool to release the ADB port, and load the software again.
