CynaogenMod 7 RC4 Gingerbread 2.3.3 for Desire HD complete tutorial(fixed broken link

For those who have not rooted thier phone yet follow all these steps.
(this can also unlock your phone if it is locked to any network)

Step 1 Radio S-Off
System requirements:

* Windows XP SP2 or higher
* .NET Framework 4.0
* HTC Sync (or ADB drivers)
* Desire HD with stock kernel (or Apache14's 1.0.7 / 1.1.4 Sense)
* It will not work on 1.72.405.3 or higher build, or new radio (12.28b.60.140e_26.03.02.26_M is ok)

So, in detail, the Root & S-OFF process goes like this:

* Install Visionary
* Open Visionary and tap temproot, then attempt permroot now. Your device will reboot.
* Connect your phone to a computer (make sure you have USB Debugging enabled. Connect charge only!)
* Open "Desire HD easy radio tool.exe" (Windows 7, right click & run as administrator), choose the first option, click "Do it"! There may be a SuperUser request on your phone, allow it.
* Done.



Step 2 Eng S-Off
* Open my "Desire HD easy s-off.exe", click "S-OFF it"! Allow possible SuperUser request on your phone.
* There could be force closes after the process, just reboot and everything will be fine.
* Done. (Remember to click the thanks button)
* Now that your device is S-OFF, Get Rom manager from the market, which will install a ClockWorkMod recovery for you. Just open it up and tap "Flash ClockworkMod recovery"
* Download a custom ROM, put it to your SD, and flash it using Rom manager or ClockworkMod itself. You can access ClockworkMod through Rom manager. It is recommended to do "wipe data / factory reset" in ClockworkMod before installing ROM from SD card.

Step 3 Install CM7
First time flashing CM 7 to your Desire HD (or coming from another ROM)?
1. Root your device and install ClockworkMod 3 Recovery.
2. Do a Nandroid backup!
3. WIPE (wipe data/factory reset + wipe cache partition)
4. Install the ROM
5. Optionally install the Google Addon
