it's the latest ruu it'll update your hboot, stock recovery, rom, and radios, to latest stock. Just download, rename the zip file to PH98IMG (don't include .zip it is a zip file it'll add it on its own in hboot) put it on your sd card, not in a folder just on. Put it back in your phone and boot to bootloader and runn the update, when it powers off. Run it again. (As it has to update the hboot to 2.27 first)Then you'll be on the stock latest. Then root and Rom from there. Of you need help pm me for my gtalk and I could walk you thru it..
