Can't find true stock Sprint ROM

[bassballboy]

All, I'm having WAY too hard of a time finding the straight Ruu_signed.nbh file for Sprint. All I can find is ex and exe files.... any help?

I'm trying to set my gf's mogul back to stock, and after using Windows mobil device center to sync it runt the relocker, it gets through til it goes to verifying phone info then errors out, not sure if this relates to not having the stock ROM or what but I'm stuck either way and getting frustrated...
