I read the stock file out and it had all checksums disabled. I ran the checksum fix and reflashed. The car runs fine but does not appear to be accepting any changes like idle speed etc... I read the file out again and noticed that the OS checksum still says it's disabled. The rest of the checksums are ok after the first calibration reflash.

I'm assuming I need to do a full reflash with the updated checksum to fix this? I've never ran into this before and I just want to make sure I'm not going to brick this E67 with a full reflash. It still runs fine as of right now with a calibration only flash. I got no errors during the flash.
