Extract the downloaded ZIP file. To avoid path length issues, extract it directly to your C: drive (e.g., C:\mtkclient ).
Extracts the secure core binary from the device's BootROM for analysis or backup.
: Used for newer chipsets (V6 protocol) where the bootrom may be patched, requiring a specialized loader file instead of hardware button triggers. Technical Setup Requirements
Unlocking the bootloader is a prerequisite for installing custom recoveries (like TWRP), rooting your device with Magisk, or flashing custom ROMs (such as LineageOS). MTK Client v5.5 simplifies this process by allowing users to unlock or relock the bootloader via a few simple commands or GUI clicks.
Disables High-Security (SLA/DAA) authentication on modern MTK chips.
You can download the MTK Client Tool V5.5 from the following reputable sources:
If BROM mode fails, v5.5 intelligently falls back to Preloader mode, providing a second channel for communication without requiring hardware modifications (like test points).
Do you need a or specific system requirements added?
For devices using newer V6 protocol chipsets—such as MT6781, MT6789, MT6855, MT6886, MT6895, MT6983, and MT8985—you will need to supply a valid Download Agent (DA) via the --loader option, as the bootrom is patched on these devices.
