Downgrading & Rooting your HTC Desire HD (Inspire 4G)

by djsharpe on April 26, 2011

Messing with the firmware of your phone can easily end in a “bricked” handset which is only of use as a paperweight. Proceed at your own risk. I am not responsible for any damages or loss which results from following the instructions below.

The problems started when HTC released their 1.72.405.3 OTA update. That update could not be rooted, and many people got stuck in stock roms. Now a downgrade method has arrived! After this process, you can use any root (+ S-OFF) method you want. Basically your device will be just like any other Desire HD with older build version.

System requirements:

  • HTC Sync (or ADB drivers)
  • Desire HD with build number 1.72 or higher
  • [Warning] Telus DHDs may lose sound because the 1.32.405.6 is not fully compatible with the sound chip. Just start using a custom ROM, and it will work fine.

How to downgrade:

  • IF you have a branded device, you have to make a GoldCard. Use “mmc2” instead of “mmc1”!!
  • Download the attached file and extract it
  • Get stock 1.32 ROM, mirror
  • Connect Desire HD to a computer. Charge only, USB Debugging enabled!
  • Open up a cmd and go to Downgrade folder, execute:

adb push psneuter /data/local/tmp
adb push misc_version /data/local/tmp
adb shell chmod 777 /data/local/tmp/psneuter
adb shell chmod 777 /data/local/tmp/misc_version
adb shell /data/local/tmp/psneuter
adb shell

If you got “#” in the result, you have temporary root! Proceed:

cd /data/local/tmp
./misc_version -s 1.31.405.6


  • Put to your SD card. You can close the cmd and set connection to disk drive. Do not put the file into a folder.
  • Reboot while holding volume down, it will go to the bootloader
  • Follow the instructions (start the update)
  • Done. You can now proceed with old S-OFF methods, and remove the from your SD. I recommend Radio S-OFF for new users.
