Are you using the latest XDF from Steveo’s website in TunerPro? If so you shouldn’t get that error.

That said, it’s nothing to be overly concerned about—the recovery patch is just a safeguard against a failed flash, we’re such a thing to occur. Without it your vehicle will run just fine, you just need to make sure the flash sequence completes successfully.

The error stems from Flashhack being unable to guarantee that the Recovery ROM won’t overwrite one of the patches you applied in the XDF. If you’re using the latest XDF from Fbodytech, this problem shouldn’t occur.
