However, if battery life, heat buildups, signal drops, Skype video call "green" issue, lockups, data stalls or lag are issues for you... since you will be doing a factory reset, consider flashing the 4.3.605.2 leaked RUU firmware, it is very stable and fixes all these issues for most people. Personally I think it is the best stock ROM for the Rezound ever! It also seems to increase battery life significantly.

Just verify the MD5 then rename the file to PH98IMG.zip an copy it to the root of your SD card (the drive that is NOT called HTC STORAGE when you connect in disk drive mode via USB), perform a factory reset on your Rezound, then reboot holding POWER + VOL DOWN, then reboot into setup but don't setup the phone, then reboot holding POWER+VOL DOWN and flash again, then the phone will reboot into setup, setup the phone, restore data, then reinstall your apps and actually run each one to finish the setup, then remove the PH98IMG.zip file from the SD card.
