This is a custom recovery for the HTC Rezound, [original thread from xda-developers here
]. This is an alternate recovery choice to the popular ClockworkMod Recovery by Koush.
To install Amon Ra Recovery:
[You must first be unlocked, see here for more info
-Place the downloaded .img file into the same directory as fastboot.
-Connect the phone to computer, and boot phone into fastboot mode ["adb reboot bootloader" is quick so you don't have to pull your battery, make sure USB Debugging mode is enabled].
-Run the command (without the quotes) "fastboot flash recovery [nameoffile].img" where [nameoffile] is the actual file name of the image file and don't forget the ".img" extension.
This custom recovery will also allow you to root your device once the recovery is installed. From recovery, select the "Developer menu" and the choose "Install su & superuser." Do NOT install the "unguarded" su.
