In the drop-down menu of SP Flash Tool, you will see three main modes.
: The initial boot code that allows the device to communicate with a computer even when the main operating system is missing. System Image
: After unlocking, the process involves extracting the boot.img file from your device's stock firmware, copying it to the device, and using the Magisk app to patch it. The app then creates a patched_boot.img file.
Flashing the correct stock firmware can resolve a variety of persistent software problems, such as: mt6739 firmware
For enthusiasts, the MT6739 chipset has received community-developed custom ROMs. Notably, there is support for , one of the most popular custom Android distributions. A GitHub repository, android_device_mediatek , provides device configurations for building LineageOS 21.0 for the MT6739 and other MediaTek chipsets. This allows developers to create a modern Android experience on older MT6739 hardware. For example, an unofficial port of LineageOS 17.0 (Android 10) exists for the K-touch i9 (Anica i9) mini-phone that runs on the MT6739.
The firmware scatter file does not match the physical chip inside the device.
Removes custom ROMs and root access to reclaim your warranty. Prerequisites Before Flashing In the drop-down menu of SP Flash Tool,
MT6739 firmware—often referred to as a Stock ROM—is the official operating system provided by your device manufacturer. It contains the complete Android OS system files, user interface, pre-installed applications, and the hardware drivers required for your specific phone model to operate. Core Components of a MediaTek Firmware Package
The MediaTek MT6739 is a low‑to‑midrange 64‑bit ARM SoC used in budget smartphones and IoT devices. Firmware for MT6739 devices typically includes bootloader (preloader), TrustZone/secure OS, LK (Little Kernel) or u-boot, the Android kernel, device tree blobs, vendor partitions, modem/baseband firmware, and Android system images. Key considerations are secure boot chain, partition layout, compatibility with scatter files, vendor blobs (proprietary drivers), and over‑the‑air update mechanisms.
Completely eradicates deeply embedded viruses or adware. The app then creates a patched_boot
If your device is stuck on the brand logo or an "Orange State" warning bootloop, replacing the system partition resolves it.
The actual Android OS, apps, and user interface.
