I've just flashed my stock EPF21B/EPF30 with this package.
All languages are included and it flyes.
The only strange thing, is that Build number doesn't show FRF91 but the system version..
So, i guess, this build won't receive official US update..i've tryied to downgrade but i always get "Main version is older".
At least, for now, it's perfect. Will see in the future what to do.
