First, put the card brush package in zip format into the internal storage of the mobile phone or the external sd card directory, preferably the root directory, for easy searching.

Press the key combination to enter the recovery mode, the volume moves up and down, and the power key confirms the selection. First of all, you need to perform a double erase operation, that is, you need to select the erase operation (data and cache) at the beginning of the erase twice, and select the yes option for all sub-options. After implementation, SMS contacts and all installed third-party software are cleared.

Then choose to install zip from sdcard, find the downloaded zip brush package, and after confirming the power supply, a progress bar will be displayed during the brush process. After brushing, you will generally return to the rec interface automatically.

Then choose to restart the system for the first time now. The new system is slow to enter for the first time, and many files and data need to be initialized. It is normal to wait for a few minutes.
