Unrooting The HTC Rezound
1. Assuming your bootloader is unlocked since you are rooted.
Fastboot Tool Download (Credit to slacker101 for the tool):
The easiest way I've found to re-lock your rezound is to download the attached "tools.zip" and extract to your desktop.
Boot your rezound into fastboot by removing your battery, putting the battery back in, holding down on the volume rocker and power. Then plug your rezound into your computer. Assuming you used your computer to unlock the rezound then you should already have the required drivers.
Open command prompt and enter the following:
cd C:\Users\[Your Name Here]\desktop\tools
Then run the command
fastboot oem lock
Your bootloader is now locked and ready to begin restoring stock recovery and rom from Stock RUU.
2. Downloading the stock RUU
*Will Update As New RUU's Are Released*
2.02.605.11 STOCK RUU EXE
1.02.605.6 STOCK RUU EXE
(will add PH98IMG.zip download for 2nd method soon)
You can do this one of two ways. You can use the exe ruu which i like to use, its simple straight forward and guides you through the process
Extract the RUU zip from the exe or download from XDA its all over.
Rename the zip PH98IMG.ZIP put on root of SD card and boot into HBOOT hit
yes with appropriate volume key and let it do its thing.
I personaly perfer running the exe. Makes life easy. But whatever floats your boat.
SIDE NOTE: IF YOU WISH TO ROOT AGAIN
the one click root tool might not work properly and will not have proper permision to install SU, If this happens flash amon through fastboot. And under development section install su / superuser, you are now rooted again
