A developers from xda-developers still working to make Android 4.0 running in HTC Desire HD, and CM9 from CyanogenMod Team also still on development. For those who can’t wait to update their Desire HD with custom ICS ROMs today we will show you how to update or install Ice Cream Sandwich Custom ROMs. You can prepare your android phone from now by getting root access and S-OFF (you can find more information about it on this post), so when CM9 or other custom ICS is roll out you can test it as soon as possible. You must notice that by rooting, S-OFF and flashing could void your warranty, we will not be responsible if anything goes wrong.

Step by Step Update HTC Desire HD to Ice Cream Sandwich Custom ROM

Root privileges and S-OFF status is required before flashing any ROMs, and also if you have been update your HTC Desire HD with 1.72.405.3 OTA Update that’s mean you need to downgrade since this update make your phone couldn’t be rooted. You can read more about downgrade method on xda-thread. If you haven’t done that’s OTA official update now you can try to gaining root, S-OFF (by installing engineering version of Hboot ) and then installing custom recovery (utility to flashing a custom android ROMs). You must read carefully from this thread to make it done.
After fulfilling the previous requirements now you’re ready to update your DHD to ICS with Clockworkmod recovery. You need to download the ICS custom ROM first (now still in progress, we will let you know once the custom firmware is available), the file is in zip format and you have to transfer it to your phone SD card.

  2. After entering CWM main menu perform Nandroid backup first, just in case you get trouble.
  3. Wipe everything from previous firmware, choose “wipe data/factory reset” option and then “wipe cache partition” option.
