Need some help for update the bios of Powercolor 5850 pcs+!!

[blade2150]

I'd sent my first card to RMA by updated the newest bios from the Video BIOS Collection.(I forgot to make a backup for it )
I am using ATIFlash 3.79
and the default version is VER012.019.000.002.000000

I dont know why I failed.
What should I do if I want to update the bios for unlock?
Where I can get the right version for it?
Or show me the other way that I could OC GPU to 950MHz without update the bios.
