How to downgrade to 1.32.405.6 WWE

About:
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
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 PD98IMG.zip 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 PD98IMG.zip to your SD card. You can close the cmd and set connection to disk drive.
Reboot while holding volume down, it will go to the bootloader
Follow the instructions
Done. You can now proceed with old S-OFF methods, and remove the PD98IMG.zip from your SD. I recommend Radio S-OFF for new users.
