Engaging in firmware modification usually involves several prerequisite steps:
Ensuring the computer can communicate with the device in Preloader or VCOM mode.
MediaTek (MTK) devices often require specific software utilities for firmware management, unbricking, or system updates. Many of these devices utilize a Secure Boot or Authentication (Auth) system designed to ensure that only authorized software is loaded onto the hardware.
Creating a full backup of the existing system and NVRAM data to prevent permanent data loss.
