Gotta go to work so I'm going to assume you have access to a windows machine. I'm basing these instructs off a Google search which gave me the version of cwm and su.zip that I THINK will work for your current setup. So here's the hopefully working plan:
Download this file, leave fully zipped, and place onto your phone's sdcard:
https://dl.dropbox.com/u/7460142/su-2.3.6.1-ef-signed.zip
Download this version of the mini sdk and unzip to the root of your computer's C drive:
https://dl.dropbox.com/u/7460142/android-sdk-windows.zip
You should now have a main folder on the root of the C called android-sdk-windows and a subfolder inside that called platform-tools. Now place the superuser zip (the 2.3.6.1 file) onto the root of your phone's sd card.
Now download this version of clockwork recovery:
https://dl.dropbox.com/u/7460142/recovery-clockwork-2.5.0.1-buzz.zip
Unzip that file to reveal a single image file titled "recovery". Place only the recovery.img file by itself into the platform-tools folder on your computer. (as a reminder it's at location c:/android-sdk-windows/platform-tools)
Now download the
Revolutionary Drivers to your computer. It's an exe program so plug in your phone via usb cable, launch the driver tool and follow any instructs. After that, I might recommend a reboot of the pc with the phone still hooked into the USB.
Ok so once the computer is back up and running and settled down, turn off the phone. Then go into hboot by pressing and holding volume down and then also holding the power button. Once in hboot, use volume keys to highlight fastboot, then press power. I believe you'll see "usb fastboot plug" or similar verbage.
Now open a command prompt on the pc. Then type in the following 2 commands:
cd c:\android-sdk-windows\platform-tools
fastboot devices
Hopefully, it will register your phone's serial number. If not, we'll need to talk further because it means you're still having driver/phone recognition issues. Assuming it worked ok, proceed...
Type another command:
fastboot flash recovery recovery.img
(should show file size and time it took to flash)
Now type
exit
Ok, unplug the phone and restart it. Then go back into hboot and this time select recovery. Should be clockwork recovery now. In clockwork, choose install zip from sdcard, choose zip from sd card, locate the superuser 2.3.6.1 zip file and flash it. Then reboot. Should be rooted with custom recovery.
I'm late for work and didn't get a chance to proof this yet so I'll check it over when I get to work. Should get you close tho I hope.
