I imported a JTAG file into v8 today and then went straight to 7.5 with the file and saved the file then reopened the file to flash it and it was a different OS than what I imported. So imported it again and saved the file with V8 and it saved it correctly. Now I know to save the file with V8 but don't understand why or how 7.5 could save the file as different OS all segments had different numbers and if you tried the flash the file I got incorrect OS error and it was the file I read from the ecm. Is this normal?
