This guide has been made considering your device is factory unlocked.

Now that legalities are out of the way lets begin!

PART 1 : Downgrade

First and foremost check the version of your bootloader.

Do this by going to the about phone panel in the settings folder.

If its 1.72 and above then follow part 1 – else move to part 2

Lets begin

What you need :

• HTC Sync (or ADB drivers)
• Desire HD with build number 1.72 or higher
• Make sure the battery is fully charged

What needs to be done:

Step one

• Download the attached file from here (right click to save file as)
• extract the file to reveal a downgrade folder and copy it onto your C drive

Step Two

• Download this file stock 1.32 PD98IMG.zip
• keep it safe

Step Three

• Connect Desire HD to a computer. Charge only, USB Debugging enabled!

Step Four

• Open Command prompt and navigate to the downgrade folder
• If you placed the downgrade folder in your c: drive type in cd/Downgrade
• It should show C:\Downgrade>

Step Five

Carefully type in the following commands one by one

• 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

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

Now type the following one by one

• Let it complete and then boot the phone

Once you phone boots up – you have successfully downgraded to 1.32 bootloader, all your data has been erased and you will start with a fresh device.
