[Tutorial] How to Generate checksum.ini for an MTK scatter file Rom
28-06-2018, 10:05 PM
This is a step by step guide on how to generate Checksum.ini for a Mediatek (MTK) based stock rom / firmware. Checksum.ini is contained in some firmware and serves to verify the integrity (hasn't been tampered with) of the firmware.
Why would I need a checksum.ini file?
Depending on how you got the rom you intend to flash and the tool you intend to use, the ROM may not contain a checksum file and some tools such as SP multidownload tool require one in order to begin flashing.
Requirements
- CheckSum_Gen.zip @ https://www.hovatek.com/forum/thread-32635.html
- Windows PC

(14-01-2019, 06:02 PM)Al Adamson how long does it take? been going for over an hour now and still not finished
due to the size of system.img , a fairly long time. if you can't wait you should consider using a different tool that doesn't require checksum to flash e.g SP flash tool
