Technical characteristics and features of the platform

The smartphone is based on a 12-nanometer MediaTek Helio G35 processor, an eight-core chipset that focuses on energy efficiency and basic performance, and is not designed for heavy gaming at high settings, but it does a great job with social media, navigation and multimedia content.

Instructions: how to reset the settings to the factory

Hard Reset is a radical method of solving software problems or preparing the phone for sale.Be sure to back up important data before starting the procedure, as all information will be irretrievably deleted. Make sure that the battery is at least 50%.

There are two main ways to reset: the first is through the settings menu if the phone is switched on and running steadily; the second is through Recovery mode, which is used if the system is not loaded or the pattern lock is forgotten (although a Google account is often required to reset the key).

To reset through the menu, follow the Settings path → About Phone → Reset → Erase all data. The system will ask you to enter the unlock password and validate the action. After that, the device will restart and begin the cleaning process, which can take several minutes.

Recovery and Fastboot: System Management

Recovery mode is a special diagnostic interface built into the device's memory regardless of the main operating system, which is logged in when the phone is turned off by clamping a combination of power buttons and increasing volume, where you can reset, remove problematic updates or start installing firmware from an external storage.

Fastboot mode is designed to work more deeply with the device, usually using a computer. It is used to unlock the bootloader, flash through the Mi Flash Tool or restore the system after critical failures.

Using these modes requires caution. Unnecessarily removing system partitions in Recovery can cause the phone to stop loading. Always be clear about which feature you are activating, especially if the menu is displayed in English or Chinese.
