3. Flashing the phone using Fastboot
A universal tool for flashing Android smartphones using a PC is the Fastboot utility. It is part of the SDK Platform Tools, which means it is suitable for a large number of devices.
Before starting the firmware, you need to get access to the system kernel. Very often, many manufacturers block this system parameter, not wanting users to change the system files of their firmware images with their own hands. To do this, you need to unblock Bootloader. To do this, you need to study the detailed instructions for configuring and managing the command line. Before starting the firmware using a computer, do not forget to enable USB debugging of the device in the engineering settings of the device.
- First, copy the .zip archive with the image, and place it in the folder with 'ADB'.
- Put your smartphone in fastboot mode and write the prompt in the command line: fastbooflash zip filename.zip, where filename.zip is the name of your firmware.
- Wait until the end of the installation and reboot the device.
