Methods/steps
Before we officially brush Meizu mobile phone, we need to perform operations such as "clearing user data and applications" and "formatting storage disks" on the mobile phone. After completing the backup operation of mobile phone data, you only need to perform the corresponding operation in the Settings-About Mobile Phone-Store interface.
Next, download the ROM package matching the mobile phone type from Meizu official website. The following points should be noted here: For users who want to upgrade to Flyme5 system:
Flyme 3 users can only upgrade Flyme 5 after "Clear User Data+Format Storage Disk" is upgraded to Flyme 4. Please make a good data backup first. Flyme 4 users can directly upgrade to Flyme 5 without clearing data.
Before we officially choose the ROM version, we need to check the current Flyme version number of the mobile phone: it can be found in the "Settings"-"About the mobile phone" interface.
According to the version number of the current mobile phone Flyme, if you want to upgrade from Flyme3 to Flyme4, you need to choose a new version rom one level higher than the version number of the current mobile phone Flyme system to complete the upgrade operation from Flyme3 to Flyme4. As shown in the figure:
Sometimes, for convenience, we can copy multiple related ROM brush packages to the root directory of mobile phone memory. At this time, we need to understand that only the ROM package named "update.bin" can be upgraded. However, other brush packages with ROM attribute but not "update.bin" cannot operate normally. Remember! ! !
Finally, it is suggested that "clear data at the same time" should be checked before the formal brushing to ensure the success of brushing.
Finally, I would like to share with you the method of Meizu mobile phone obtaining ROOT permission and the method of restoring the backup data of mobile phone. The latest version of Flyme system comes with ROOT permission, just open it. Of course, it can also be implemented with the help of third-party ROOT tools.
For Meizu's mobile phone data recovery operation, when the mobile phone backup operation has not been carried out, the operation of brushing the machine or restoring the factory settings has been carried out. We need to use related mobile phone data recovery tools to complete Meizu's mobile phone data recovery operation.
