Just place it in the root of SD card and reboot to your boot loader
Sent from my Rezound
OK, I did RUU in the past but forgot process.
So no need to relock bootloader since I am S-Off?
Given the RUU is 4.03.605.2 do I still need to use the second PH89IMG from REV3NT3CH's thread, or is this RUU all I need?
Thanks for fast response
