i think your tool doesn't calculate the correct cks dfox uses a fix for this kind of problem, i don't know what tool you used

i used always kess on mm8 gmf, always worked…the checkum is right for what the tool write (only the last part of file)…for this type of job on the first part on file i think need bench mode or jtag mode (or one tool that write obd from address zero)…kess read full data via obd but write only the mod file, not full from address zero
