Warning thanks to hacktrix2006:
Also before anyone continues make sure you run cat /proc/kmsg | grep 'mmc0:0001' If you have a M4G2DE EMMC stop do no use clockworkmod recovery or even try to root as you will fry your EMMC.
If you have SEM04G EMMC then your safe to continue.
If your using the PD98IMG.zip from the retired AAHK just remember its no longer support.
Personally i would use the firmware.zip file from the tutorial which is included in the http://tau.shadowchild.nl/files/ace-tools.zip its safer that way just remember to backup your boot.img as its important if you want to boot back into sense 3.0.
Download this and unzip it somewhere (reccommend C:\ root folder): http://www.multiupload.nl/MXW371YT87

3.3 copy the ROM zip file to your SD card.
4.Install recovery image:
Open cmd and type:
•cd (eg cd C:\ace-tools)
Ensure your phone is connected to your PC and then boot into bootloader, then navigate to fastboot.
•fastboot flash recovery recovery1.img
5.boot into recovery through bootloader and Install the ROM you placed on the SD card, (via install zip fileselect the rom zip)
6.Reboot the phone, ensure the rom is working fine and you have root access you can test this by turning on usb debugging then:
You should see the $ turn into a #. If this happens, congrats you have root access.
Then type this:
•Adb push boot.img /data/local/tmp
dd if=/dev/block/mmcblk0p22 of=/data/local/tmp/boot.img
•adb pull /data/local/tmp/boot.img
•adb push goldcard /data/local/tmp
chmod 775 /data/local/tmp/goldcard
take note of the string of numbers and letters that appear.
•adb shell /data/local/tmp/goldcard -c -o /data/local/tmp/goldcard.img
dd if=/data/local/tmp/goldcard.img of=/dev/block/mmcblk1
•adb push misc_version /data/local/tmp
•adb shell chmod 775 /data/local/tmp/misc_version
•adb shell /data/local/tmp/misc_version -s 126.96.36.199
7.If this is all fine boot into bootloader again.
From bootloader go to fastboot.
Go back to the cmd window on your PC from earlier, type in:
•Fastboot oem lock
•fastboot oem rebootRUU
•fastboot flash zip firmware.zip
unlock the bootloader again using the Unlock_code.bin you got from HTC:
•fastboot flash unlocktoken Unlock_code.bin
then flash boot.img in ace-tools folder:
•fastboot flash boot boot.img
•fastboot flash recovery recovery.img
8.boot to recovery again then:
•adb push gfree /tmp/
•adb shell chmod 775 /tmp/gfree
•adb shell /tmp/gfree -f
reboot to bootloader and you should see it says S-OFF at the top of the screen, if It does congrats your done.
