Easiest Root Method
– The easiest root method for the HTC Desire Android phone
[STEP1]- Check Hboot version. Poweroff, and hold Volume Down & Power (it’s the number after “HBOOT”. Examples are 0.75xxxxx, 0.83xxxxx, 0.93xxxxx, 1.02xxxxx)
[REVOLUTIONARY]- If your HBOOT version is 0.93 or above (NOTE: Version 1.03 is NOT supported) then continue, if it is below then use the Alpharev method.
[REVOLUTIONARY][STEP1]- Go to revolutionary.io and go to the “Downloads” section, Pick your operating system, choose device as HTC Desire, and choose your HBOOT version (you should already know this from STEP1). Then enter your serial number, it can be found in “about phone” or behind the battery.
[REVOLUTIONARY][STEP2]- Read the documentation page and download these fastboot drivers.
[REVOLUTIONARY][STEP3]- Make sure HTC Sync is disabled, if you have it installed on your PC. Plug your phone in via USB and make sure USB debugging is turned ON (settings> applications)
[REVOLUTIONARY][STEP4]- Extract all of the tools from the revolutionary.zip file and run revolutionary.exe. A CMD window should pop up and show you the progress (See  for how it should look like).
[REVOLUTIONARY][STEP5]- When the process is almost finished, it will prompt you to flash a custom recovery, type YES or Y. Follow tutorial number  if you would like to flash a different recovery – This is optional and not required if you decide to flash recovery during the revolutionary process.
[REVOLUTIONARY][STEP6]- Download superuser.zip, put it anywhere on your sd-card (preferably in a path you can remember). Boot into recovery by holding Volume Down & Power (You will see lines of green text flash, this is normal), then using the volume keys to navigate to RECOVERY, and use POWER to select. The phone will now boot into recovery.
[REVOLUTIONARY][STEP7]- Once you are in recovery, use the trackball (if it’s broken then use volume keys) to navigate to “install zip from sd-card > choose zip from sd-card > #directory where you put superuser.zip# > superuser.zip > yes”
[REVOLUTIONARY][STEP8]- After the process is finished, reboot, and your phone will now be rooted.
