Why it happens: You are trying to write to a protected region (like seccfg or proinfo) without the proper authentication or with a locked bootloader.
Fix: Unlock the bootloader via fastboot oem unlock first. Or use Format all + download (but this wipes IMEI).
Here’s a snippet from a working MT6833 scatter file: mt6833 scatter file work

See that 0x20000000 for super? That’s 512 MB. Try to write a smaller super image and the tool will error out with size mismatch. Why it happens: You are trying to write
To resize userdata:
Save the file with Unix line endings (LF, not CRLF). SP Flash Tool chokes on Windows line endings.
A scatter file contains information about the layout of the firmware on a device's internal storage. It tells the SP Flash Tool where to place different parts of the firmware (like boot.img, system.img, userdata.img, etc.) during a flash operation. Essentially, it guides the tool on how to properly distribute and write the various images to their correct locations on the device's storage. See that 0x20000000 for super
It was a typical Monday morning for Alex, a software engineer with a passion for mobile technology. His day started like any other, but little did he know, it was about to take an interesting turn. He received an email from his team lead, mentioning a new project involving the porting of a custom ROM to a device powered by the MediaTek MT6833 chipset. The challenge? The team needed someone to crack the code of the scatter file, a crucial component in flashing and modifying firmware on MTK devices.
