First volume of the M325F scatter firmware at binary U4, a model code matching the Samsung Galaxy M32. This 1.95 GB RAR must be combined with part2 before extracting. Scatter packages are meant for MediaTek chipsets and are written with SP Flash Tool or a compatible service box that reads the scatter map. Technicians use them for dead-boot repair or full partition restoration. Check that the binary version on the device matches U4, and back up NVRAM and IMEI data before flashing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @mrepairo. Enginerys does not host this file.
