Always SIGN_ERR01 on USB insert on Sync 3.2

I know that someone was changing it to support EU frequencies - its imported from the US originally. I swapped back the ACM 727-04-01 to North America (0) and the Country Code to 5553 (US) when it didn’t want to update, but I had no luck. Is it possible that some other options are forbidding me from updating?
