The TSB states that the reflash fix is for the Si. Here's a copy of it at TOV:

Are you sure that the reflash works for the EX/LX too?
If it does, then what if the service advisor gives you grief about it? What should you say? After all, it doesn't say in the TSB that the reflash is for the EX/LX as well. It only says it's for the Si. He would have a point there.
