Here is a step by step tutorial to generate checksum.ini file for MediaTek devices. In this guide we are sharing latest MTK checksum generator tool which you can use on Windows pc to create new checksum.ini for MTK firmware.

Basically MTK checksum file contains some firmware verification files. So that, at the time of firmware flashing or frp bypass process tool uses this file to verify the integrity (hasn’t been tampered with) of the firmware.

In case, tool is showing checksum.ini doesn’t exist error that means you need to add checksum file with your stock firmware. Otherwise, tool will not start flashing process. Most of the time, this error accrues because of missing checksum file in firmware.

It is must to know that MTK sp flash tool can flash official firmware on MTK without checksum files but some tools such as SP multiportdownload tool and SWD after sales tool require one in order to begin flashing.

Another most important this is that “checksum.ini doesn’t exist error” or “image preloader checksum failed error” are different from each other. MTK checksum.ini doesn’t exist error can be fix by generating new checksum file with the help of MTK checksum.ini gen tool.
