How to Create a Checksum File for MediaTek (MTK) Scatter Firmware/Stock ROM? To use this tool, you have to paste it in the firmware folder and run its setup file, which The program/tool starts the process of creating a checksum file. This tool is portable, and there is no installation setup to use this program. There are no restrictions of any kind in this tool.
This tool is licensed freeware, and any user can use this tool at any time or create an unlimited checksum file from it. This program uses cmd.exe (command-line interpreter) to create the Checksum.INI file from the scatters firmware/stock ROM file. The Checksum Generator Tool is a small GSM-based Windows operating system program developed by a third party. When the firmware is flashed on the mobile device, the checksum file then verifies the integrity of each file to ensure that the firmware files are correct or that someone has tampered with them.īelow is an example of a checksum file data generated by the Checksum Generator v7.1536.00 tool. ini extension and contains information about all the firmware partitions. The checksum file is a way to verify the integrity of the firmware/stock ROM files, and the checksum file is in the. What Is a Checksum File, and How Does It Work?
What Is a Checksum File, and How Does It Work?.Notice that one bit is changed, if we use checksum, we can detect this sort of thing. Let's say we have this data (represented in binary) :Īnd then we send the data over the network, after that the recipient receive: ExampleĬhecking can be used for some applications such as data transmission Though, this way not hacker-proof since, the hacker (or man in the middle) can also change the CRC hash to be the same as the CRC of message modified.ĬRC often called a checksum, but it is not a sum, because it is represented as long binary number instead of the sum. If the CRC hash is different, then there's a possibility of data change on the message. Upon receiving the message, the recipient try to calculate the CRC of the message and compare it to the CRC sent which included on the message. Lets say we want to send our message to someone else, to make sure the data didn't go through unintended changes (small changes, maybe because it goes through unreliable connection/wire), we can put CRC hash in the message. In the real world, usually CRC used when sending data.
Cyclic Redundancy Check 32 bit (CRC-32) Hash Checksum GeneratorĬyclic Redundancy Check (CRC) is an error detection code used to detect changes and verify the data, usually on data transmission.
