I never had to do this before so my knowledge is limited, but if you look at post #4 from that link it says all you need is the stock ruu to rewrite everything.
So what I would try is installing the rooted ruu and flashing the radios (you can find those from the same page). After that do the ##RTN# with your MSL #.
You can get the MSL# by going to the market and typing MSL. You will get the app to read it.
Again I'm limited with the but this is what I would try first.
