Please, download the files, only if you need them.
A phone with S-OFF is better to be flashed with the Universal Firmware-3.33 from the main page that has 4Ext Recovery included.
Be warned, that in these files below, there are included "boot_signed.img" and "recovery_signed.img" that are hTC Stock!
