This stock rom is only for the Boost Mobile version of the phone. You will get a version is too old error if you are on the Sprint version!
Don't have or want CWM? Well I finally got a method of rooting this phone that does NOT require CWM at all! Only downside to it is that this method will wipe your data and app settings. You will need to reinstall apps and your settings once you are done.
First you must unlock your bootloader as that remains the requirement before you can root or flash anything to this phone. If your boot loader is already unlocked, then your good to go and ready to root the phone.
You can find instructions on how to unlock your phone here: Welcome to HTCdev
Once you got your boot loader unlocked you should be able to flash a custom rom to the phone now. If hboot says "Unlocked" highlighted in Pink at the top left corner of the screen, then your boot loader is unlocked and you can flash this update.
To install this stock root rom (comes with Titanium Backup preinstalled as wall) download and copy the PH44IMG.zip file posted below to the root of your SD card and simply power off the phone by pulling the battery, then after putting the battery back in, hold Power On + Volume Down buttons to boot the phone into hboot.
If you see a mostly white screen with 3 little androids at the bottom, then you were successful. hboot will start searching for the file in a few seconds and will load it. It will take awhile. This is normal.
Once it says it's ready to flash it, hit Volume Up to accept the update and it will start flashing it to your phone. Make sure your battery is charged past 35% before you start this and don't power it off before it finishes.

This will flash stock root with OTA June update and Titanium Backup preinstalled! Aside from that it is untouched stock and should still accept OTA updates provided that you have made sure to resintall any bloatware that you might have removed with Titanium Backup afterwords.
If you run into problems or need to flash the official rom back to the phone, you can use this: (please note this will also flash stock kernel and stock recovery back to your phone. Be aware of that if you have CWM installed)
fullstock_PH44IMG.zip
(rename file so that it reads only as "PH44IMG.zip" or hboot will not recognize it)
Now you can flash direct to root with no CWM required!
