Looks like me7sum cannot be used on this file, unfortunately.

You should have posted the output of me7sum when used on the ORI.

If you have the ability to pull the eeprom too we can technically turn off CS checks all together.. But not if your not comfortable doing bootmode back and forth for testing.
